PDFtoMusic is a groundbreaking and unique program that converts Adobe PDF music sheets into editable music scores.
From an Adobe PDF file created by any music notation program, PDFtoMusic can play the piece, sing the lyrics and export this piece to miscellaneous file formats: MIDI, Myr, BMP, WAV, AIFF and MusicXML  for the Pro version.

What can I use it for?

Usages for PDFtoMusic are numerous. First, on the Internet, many dedicated sites provide large collections of free musical PDF files.
PDFtoMusic will let you play them, or convert them into a music file format that you'll be able to modify by using your usual music notation software.
Thus, PDFtoMusic gives you access to a wide library of public domain score sheets that you can play or edit.

Also, there are many music notation programs, and only a few manage compatible exchange file formats. PDFtoMusic solves this issue. You just have, from your program, to generate a PDF file (see next chapter), read it with PDFtoMusic and convert it into format that can be read by another application, for instance, Myr or MIDI format (or MusicXML for the Pro version).

PDFtoMusic becomes then a bridge between your miscellaneous music programs.

For instance: your choir master only uses "Music Architect 2000", that can only save files in its own, proprietary format. You just have to ask him for a PDF file for the score, and by using PDFtoMusic, you'll get a score that can be edited in Harmony Assistant.

If you own the Pro version of PDFtoMusic, you can also export into MusicXML exchange format, from Recordare.  The Music XML file format is currently supported by a number of notation applications, including Finale and Sibelius.

How does PDFtoMusic work?

PDFtoMusic analyzes the content of Adobe PDF files. It collects all the graphical information that it can process: fonts, lines, miscellaneous graphic objects. From these graphical items, PDFtoMusic will infer the music score to be played.

Note : some PDF files (albeit rare) embed only a single picture for the whole score, instead of  a collection of simple graphic objects. This kind of PDF file has probably been generated from a scanned paper sheet. PDFtoMusic can't extract and process elementary graphical items in such cases, and reports that such a document cannot be processed.

To convert a PDF file, select "File>Open" in PDFtoMusic and select a PDF file on your hard drive. PDFtoMusic will load it, and start automatically to process and display it.
If PDFtoMusic makes a mistake while processing the document, you will be able to fix this mistake manually. It is described in the corrections section of this manual.

PDFtoMusic can export the result automatically each time a PDF file is processed, and open this result in the program of your choice.

What are the differences between the "Pro" and "Standard" version?

The "Pro version" includes options and features that are not present in the "Standard" version:

- Batch file export, to convert in only one operation all PDF files from a folder and its subfolders.
- "Expert" mode to manually override individual default processing settings in order to have more precise control.
- Export in MusicXML format in order to preserve the score sheet layout when importing into one of the numerous programs that support this format.

How do I generate a PDF file from any software?

PDFtoMusic is able to convert a PDF document with such a high level of accuracy because it analyses the actual font characters which are embedded in the PDF document. 

When asking for generating a PDF document, you must ask for the character fonts to be embedded into the PDF document. Generally, it's the default setting.

If PDFtoMusic detects a font that is not embedded in the document, an alert will be displayed:

meaning that the rendering could be different from expected.

Here is how to create a PDF file, depending on your system kind:

With Windows

  With Mac OS X

  With Mac OS 9

  With Linux

With Windows

To create PDF files from any music software (or any other application) under Windows, you must install a small program beforehand.
This program can be either a freeware, like DoPDF, PrimoPDF, PDFCreator, a shareware, like  PDF995, or a commercial software package like the tools of the Adobe suite.

Note : Be careful, some freeware programs likePDFCreator  CutePDF ou Bullzip PDF Printer install unwanted adware toolbars in your Web browser. It's highly recommended to disable installation of these toolbars when possible, or to use any other adware-free alternative.

All these programs behave like a new printer for your computer.
When "printing" a document to it, a file name is asked, and the printing result is actually saved in PDF format.

When printing from any program, you will then find a new entry in the printer selector that appears:

Select the printer (here "PDFCreator) then click "Print".
You'll then get a window for entering optional information about the PDF file to be created (Title, date, author...), then a file selector for specifying the name and location of this file.

The PDF file that matches what you asked for being printed is then generated, and can be opened by PDFtoMusic.

You can then either send this file by e-mail to somebody else, or process it with PDFtoMusic to convert it into the file format you need.


With Mac OS X

With a Macintosh under Mac OS X, it's quite easy to generate a PDF file from any program, by using the print dialog box. Once the file is loaded into the software, select "File>Print". The printer selector opens, and you can select here the page range to be printed. 
In the bottom part of this box, you'll see a "PDF" or "Save as PDF" button.

Click it, select a name for the file and save it. The Adobe PDF document is created on your hard disk at the required location.

You can then either send this file by e-mail to somebody else, or process it with PDFtoMusic to convert it into the file format you need.


With Mac OS 9

To create PDF files from any music software under Mac OS 9, you must install a small program beforehand in the system "Extensions folder", like Acrobat PDFWriter or PrintToPdf.

Select the Chooser from the Apple menu, and click on the program icon:

Then close the Chooser. (The AppleTalk setting is irrelevant in this case.)

All these programs behave like a new printer for your computer.
When "printing" a document to it, enter a file name, and the printing result is actually saved in PDF format.

A PDF file of your score is then generated which can be opened by PDFtoMusic.

You can then either send this file by e-mail to somebody else, or process it with PDFtoMusic to convert it into the file format you need.


With Linux

Generating a PDF file from any program under Linux needs to use a special printer driver that saves the graphic commands into a file instead of actually printing them on paper.

You can then either send this file by e-mail to somebody else, or process it with PDFtoMusic to convert it into the file format you need.

With KDE, the "kprinter" command (KDEPrint package) includes an option to generate a PDF file:

If this option is not included in your distribution, you'll probably need to use cups-pdf.
To install it under Ubuntu, please refer to this document:
To install it under another distribution, please read:

"Correction" menu

As any other system based on computer recognition, PDFtoMusic is not infallible, and can make some mistakes, more or less impiortant depending on the quality of the document. You can interevene on the recognition result and apply amendments. These changes can be saved so that they are preserved when loading the document again.
PDFtoMusic offers two ways of saving these amendments.

In a general way, when using PDFtoMusic, always start by listening to the result through the "Performance > Play" menu option. If you hear any mistake, this mistake will probably be also present in the exported file. So it's highly recommended to fix it with the available tools, the "Correction" menu being one of them.

If no PDF document is open when you change a setting in this menu, it will apply to all future opened documents, otherwise it will apply to the frontmost document.

In some cases, changing a calculation setting for a document will need its total or partial recomputation.


For each staff found in the document, PDFtoMusic shows the related instrument. You can change this instrument as well as its volume, panning position, octave shift and semitone shift.

Through the semitone shift you can specify that an instrument in the score is a transposing instrument. For instance, a staff written for a clarinet is usually notated as a Bb transposing instrument (its semitone offset is -1) and an alto Sax as a Eb transposing instrument (its semitone offset is -9).

If the instrument is human voice, you can specify the language that Virtual Singer will use for singing the lyrics.

A check box activates globally the "surround" effect. This effect increases the panning separation of the miscellaneous instruments, for all the documents.

Staves and systems

When a line is full on page, music notation makes the whole set of staves restart at the next line. Each group of staves that are played together from left to right on page is called a system. There can be several systems on each page.

In order to save space, staves that don't play across a system are frequently not displayed in this system.

This can lead to tricky situations, where it becomes difficult to know which staves are part of the next system, and which staves aren't. For instance, if an instrument doesn't play in a system and is hidden starts to play at the next system, while another instrument stops playing, the number of staves in the two systems can be the same, while the staves aren't. In this case, only the staff name, its clef, or other indicators enable to understand the score structure.

PDFtoMusic includes specific algorithms that "follow" staff lines from a system to another. The "Staves and Systems" mode lets you change the way staff lines are connected together.
A description is provided here.


In this mode, you can define excluding or including areas.
These areas apply to character or line objects

- If at least one inclusion area is present on the page, all objects located outside any inclusion area are ignored

- Any object located in an exclusion area is ignored

This can be useful, for instance, if a group of characters is not well managed and troubles the recognition.
To add an area, click and drag.
To delete an area, right-click it then select "Delete" in the contextual menu
In the same menu, you can define what page range the area applies to.
Areas are saved along with the amendments made to the document. The "Edit > Delete all changes" menu option therefore also deletes all areas.


A PDF document includes graphic objects (frames, lines, etc) as well as characters extracted from a font. Those characters can be either letters and digits, or music symbols.

PDFtoMusic has some manual font recognition settings that can help correct mistakes, which are described here.

Allow multi-voices staves

If PDFtoMusic considers that one or several staves in the document are made of several voices and you are sure of the opposite, you can deactivate this processing mode.

Allow enhanced chords

Two notes horizontally very close to each other can be considered as belonging to the same chord (there are sometimes chords in which the notes are not perfectly aligned). This option enables you to deactivate this mode.

Allow tuplets

In some scores, a digit appears near the note to indicate the fingering. In some cases, PDFtoMusic interprets this fingering text as tuplets (triplets, etc). If there are no tuplets in the piece, deactivate this option to prevent PDFtoMusic from searching for tuplets in the score.

If you deactive this option, PDFtoMusic will no longer search for tuplets in the score.

Allow fingering

If PDFtoMusic recognizes tuplets as fingering notation (this generally provides a bar duration error), you can deactivate fingering seeking for the whole document.

Allow key changes

It can be sometimes difficult to tell accurately whether the accidentals at the start of a bar are a key change, or regular accidentals that has to be applied to the following notes.
For instance:

If PDFtoMusic finds key changes on a document that doesn't include any, deactivate this processing mode.

Allow time signature change

If wrong time signature changes are added inside a measure line, disable this option.

Allow lyrics

If some textual informations, near the staff are recognized as lyrics, and the document don't include lyrics, you can disable them whith this option.

Allow shared lyrics

In some vocal pieces (for instance, Barbershop scores), when several performers sing the same lyrics, only one lyric line is written:

When this mode is active, PDFtoMusic will assign the lyric line to both staves.

Allow clefs vertical shift

Is this mode disabled, clefs vertical position will be ignored

Allow bracket to create groups

Normally, staves groups are notated with braces. Is this mode is active,  bracket also create groups.

Allow left and right hand fusion

Groups of two staves joined by a brace are merged into one part. If not active, this allows you, for example, to export the left hand and the right hand separately.

Allow chords name

In some cases, the lyrics line can be constituted by chords names, for example when the singer sing "La La La La". Invalid this option to ignore chords name processing and add the texts to lyric line and not chord line.

Allow complex typography in chord names

In some case, chord names are written using miscellaneous fonts, size, or vertical shifts.
Activate this option to got a more flexible chord names recognition.

Allow special lines

Some PDF draw note stems with rounded lines :

Some programs draw staff lines using characters mixed with standard lines.

Some programs draw dots using small rounded lines.

When this mode is enabled, these lines will be processed.

Allow thin beams

Some PDF draw beams with thin lines :

When this mode is enabled, these lines will be processed.

Allow automatic break adjustment

Some PDF include several lyric lines related to the staff with incorrect break symbols (repeats, jumps, endings). When this mode is enabled, PDFtoMusic tries to create breaks symbols in order to match the actual number of repeats.

Allow multi-rest

If some numbers below the staff are recognized as multi-rest, you can disable them with this option.

Allow short barlines

In some old notations, barlines are displayed as a small vertical line : 

When this option is on, these lines will be processed as regular, full-length barlines.

Allow ledger lines

Ledger lines are used to determinate note pitches when the symbol is outside the staff lines.
If there is no ledger lines, notes will be lost. In this case disable this option.

Allow tempi

If tempo changes are incorrectly found in your document try to disable this option.

Allow dynamics

If dynamics are incorrectly found in your document try to disable this option.

Allow group names

If group names are incorrectly found in your document try to disable this option.

Allow modern notations

This option is still experimental. It aims to enable specific algorithms to handle special cases.

Processing of time signature located above the staff.

Allow grace notes

If little notes are processed as graces, disable this option.

Allow big images

Eliminates images that are too large and can disrupt visualization. By default, all images which are larger than 25% of the page. On PDFtoMusicPRO this threshold is adjustable in the "Images" tab of the expert mode.

Staff matching over systems

With this option, you can change the way the software follows automatically a staff across systems (see "Staves and Systems" above)

The most complex levels are usually more accurare, but could slow down significantly the whole process (up to several dozens of seconds per page)

The different possible levels are:

High resolution

When a document is made of many tiny staves, some inaccuracy errors can occur in the vertical positioning of notes and rests.
Switching to high resolution increases the precision (and the computation time). You can define that all documents will be loaded in high resolution from the general preferences.

Reset to default settings

This applies to all settings from "Allow multi-voice staves" to "High-definition".

• If no PDF document is open and this option is inactive, then all default calculation settings are already identical to the factory's.
This option is active when at least one default setting has been changed.
Differences are displayed in bold, and you can reset them all to factory settings either by selecting this option, or manually, one by one.

• If at least one PDF document is open and this option is inactive, then the settings for the frontmost document are aleady indentical to those by default.
This option is active when at least one setting has been changed for this document.
Differences are displayed in bold, and you can reset them all to default settings either by selecting this option, or manually, one by one.

"Settings" menu

This menu enables you to set up the PDFtoMusic behaviour. Don't hesitate to explore the numerous options carefully. These can prove to be very useful.


Opens the general preference window. You can adjust from here the way the PDFtoMusic interface will react. The miscellaneous options are arranged in sections.
A complete description of each section is provided here.

General points
Saving files

General points

While loading and processing a PDF file, analysis progress is shown through icons. You can cancel the processing at any point by hitting the "Esc" key or by closing the window.

Once the analysis is complete, the PDF drawing is displayed in a document window.


The toolbar in the upper part of this window enables you to play music, navigate within the score, pause and restart playback and adjust volume or tempo (playback speed).


If the document contains several pages, the following icons enable you to switch to the previous or next page. You can also use the vertical scrollbar to move through the whole document.

The next icons change the display scale of the document.

The "info" icon displays information about the document. These details are extracted from the PDF file: title, document author, creation date, as well as the character fonts embedded in this document.

If the Adobe PDF document include lyrics, the "bird" icon is present. Click this icon to activate the virtual singer before starting playback. This default setting can be changed in Preferences, "Document" section.

The "export" icon exports the music piece in the current format specified in general preferences, "Export" section. But you can also select another format from the file selector, by typing in the matching extension. For instance, to export in Wave format, end the filename with ".WAV".
You can cancel the export at any time by hitting the Esc key.

Right-clicking (or Shift + click) on the toolbar changes its appearance.

The "Setup..." option enables to customise the toolbar icon list according to your needs.


If your document contains several pages, the last icon opens and closes the drawer. A drawer is a secondary window, linked to the main one, that shows a general preview of the document. Click a thumbnail to jump directly to the selected page.
If errors have been found, a warning sign is displayed, specifying the number of errors detected on this page.


Saving files

When amendments have been applied to the document, as for instance a change in the instruments, volume, or music symbols recognition, you can save these changes so that they will be preserved when loading the file again later.
PDFtoMusic lets you choose beween two modes that can be set up from general preferences.

1- Save changes in the Adobe PDF file itself
(When Settings > Preferences > Document > Store corrections in PDF file is checked)

Data is preserved in the Adobe PDF file. A backup copy of this file is performed. This doesn't affect the way this PDF file is displayed by other programs.

The advantage to this mode is that, when you send the file to somebody else, your changes are carried along.

2- Save changes in a separate file
(When Settings > Preferences > Document > Store corrections in PDF file is not checked)

The original Adobe PDF file is not modified, and the data are stored in a separate file, created in the "Correction" subfolder of your user file space.

Please note that, in this mode, you can still generate a PDF file in which your amendments are embedded by using the "File > Save as..." menu option.


This dialog box enables to set up the PDFtoMusic behaviour. Don't hesitate to explore carefully the numerous options. It can prove to be very useful.

Apply corrections drop-down menu
Defines the default settings for the "Correction" menu options when a new PDF file is processed. Each of them can be activated/deactivated on a per-document basis through the menu.


Display processing errors into a text window

When PDFtoMusic detects an error when processing the document, it will display a small icon over the document itself representing each item you have ticked in the Alerts panel of general preferences.
In parallel, PDFtoMusic can create a list of all errors encountered as text in a special window (pink background). Right-clicking this window opens a contextual menu for erasing, saving or printing the window content.

The following items enable you to mask some errors (these errors are still present but no longer displayed). Here are the descriptions of the miscellaneous processing errors

Display "Impossible to apply beam"
PDFtoMusic recognized a character that looks like a beam, but couldn't find any music symbol close enough.

Display "Impossible to apply ornament"
PDFtoMusic located a character that looks like a note ornament, but couldn't find a note close enough.

Display "Broken slur"
PDFtoMusic recognized the shape of a slur (possibly a tie), but either it could find the source note for this slur but not the target note, or it could find the target note but not the source. It therefore can't apply the slur.

Display "Impossible to find a measure for this symbol"
PDFtoMusic recognized a musical character in the document, but could not relate it to any measure (bar) area. It can happen for instance for some time signature indicators that are put as a reminder at the beginning of a line.

Display 'Impossible to find the reference note on tablature"
When the document shows tablatures for fretted instruments, PDFtoMusic estimates the duration of notes written on the tablature by seeking for the matching note in the regular staff. If PDFtoMusic can't find this reference note, it generates this error.

Display "Incorrect measure duration"
When several staves are present in a single system (staff group), PDFtoMusic checks that the duration of each bar is consistent. If PDFtoMusic detects a difference in measure duration, this error is generated. It can occur in the following situations:

    . PDFtoMusic made a previous miscalculation either when extracting the symbol duration, or when locating chords within the measure (especially when notes in chord are not on the same vertical line)

   . There is an error in the source score's notation. This may depend on a number of factors, including the overall accuracy of the source program used to create the PDF.

In some cases, PDFtoMusic can consider two notes that are horizontally close together to be in chord, instead of considering that they are consecutive.
By un-checking the various options in the "Correction" menu, you can deactivate the display of specific types of errors that cause "Incorrect measure duration" warnings.


The export settings don't affect batch processing, which uses its own options.
When loading a PDF file, PDFtoMusic analyzes it automatically. It can then export it immediately in any of the available formats, and open this resulting document in an external application. The following options are available in the Export tab of the Preferences:

Export all opened files automatically
This check box activates/deactivates the automatic export.

"to folder..."
If automatic export is activated, use this option to select the path to the folder where the resulting documents will be stored.

The "Change" button enables you to select another (file) path.

"File format"
This pop-up menu lets you select the export format to be used (Cf appendix about format description)

Don't export page setup
When this option is active, measure size, space between staves, page breaks, objects related to pages are not exported. Number of measure by line is set to 4. This mode is automaticaly enabled when we ask to export a reduced number of parts.

Open automatically exported files
When this option is active, each exported document will be opened automatically by the program of your choice (it supposes that the selected software is capable of reading this kind of file).

The "Edit" button enables you to select the application that will be used for opening each of the export file formats.
The "Delete" button lets you specify that you don't want this format to be processed.


PDFtoMusic uses optical recognition algorithms on music fonts to detemine the meaning of each symbol.

Store glyphs into a cache
When this option is ticked, symbols that have already been encountered at least once will be processed more quickly.
However, activating this option can lead to a bigger memory consumption.

Erase font cache at exit
When this option is not ticked, glyphs are preserved from one session to another.
Deactivating this option can lead to a bigger memory consumption.

Note: the glyph cache is located in the preference folder:
"Myriad Preferences/PDFtoMusic/GlyphesData". Please do not apply any action to this folder while PDFtoMusic is running.




Kooplet is a search engine specialized in music scores.

From a note pattern Kooplet will display a list of documents from the Internet that contain this pattern.
Processed file formats are those containing all necessary information to provide an editable score. For instance, digital audio formats (wav,aiff,mp3,etc) are ignored.
Kooplet will provide links to files in Myr, PDF, Mu3, Mus, XML, MXL, Abc, Etf, Tef, Nwc, Enc, Tab, Mid, Kar, Mod, S3m, Cmf, Sty, Rhp, Etf, Gp5, Gp4, Gp3 or Gtp format.
PDF files can be converted by PDFtoMusic or PDFtoMusic Pro, the others can be imported directly in Harmony Assistant.
By clicking the "Play" button below the search result area, you'll be able to hear the note pattern in its context.

Three search modes are available. Search mode can be selected from the first icon in the toolbar:

- Search for pitch, regardless of the rhythm

- Search for rhythm, regardless of the pitch

- Search for both pitch and rhythm
It is also possible to search music score files for text, as well in the titles or comments as in the lyrics.

If a text and a music pattern are entered, result documents match both the text and the pattern.

Contrarily to other generic search engines, Kooplet extracts information from within the music file content.
Documents are not stored on the Kooplet servers but remain on the site where they have been found. Therefore, when downloading or viewing a document, you will read it directly from the original site that hosts it.

The toolbar

The toolbar changes according to the selected search mode, or whether you insert notes or rests, etc.
From left to right, you can find:

Search mode selection
- Start and stop pattern playback
- Delete the whole pattern
Pattern input from the microphone (experimental)
- Sharp mode for note input
- Note/Rest input mode
- Symbol duration
- Dot mode


You can add symbols by clicking the virtual keyboard.
If you click the keyboard or the staff with the Shift key down, you hear the note without inserting any symbol.
If you click a symbol with the Alt key down, it is deleted.
If notes are selected in the frontmost document before Kooplet is activated, these note will be used as search pattern.

Advanced search

When searching for a text, if you write the words between quotes, search will be performed on these words in this order. Without quotes, it will be performed on these words in any order.
For instance, if a score contains lemon tree, it will match the tree lemon search, but not "tree lemon" between quote marks.

If you write a minus symbol before a word, this will have to be absent from the document text.
For instance, if you search for Ave Maria -Gounod, matching files will contain the words Ave and Maria, but not the word Gounod.

The "Setup" button set up the search broadness.


No recognition algorithm can be 100% reliable. In the event you encounter translation errors, PDFtoMusic offers some tools to help you fix them.

Staves and systems


PDFToMusic extracts character fonts from the PDF document, in order to "read" the music sheet. However, when a PDF document is created, fonts are not stored as is in the file, but transformed. First, to shrink the file size, only used characters are embedded.The name of the font is also often encoded. Moreover, no clue is provided that would enable PDFtoMusic to distinguish it without fail.

Some portions of text can be written with a default font (Times, Courier, ...), directly managed by the PDF format. In such cases, the font is not included in the PDF file and won't appear in the recognized font list.
In a first step, PDFtoMusic tries to extract a consistent font name, and searches for it in its known font name database. If the name is found, the font is considered as "forced, application". You can't change this status.

If the first step gets nowhere, PDFtoMusic applies dedicated algorithms to distinguish between text and music fonts. Fonts are then marked as "Text, auto", or "Music, auto". You can change this status through the "Correction > Fonts" menu option and, for instance, change a text font to music font. 

Tip: double-clicking a character on the PDF document opens this window with the matching font selected.

This change can be limited to the document or applied to all documents.
If limited to the document, only the current document will be affected by this change.
If applied to all documents, each time the font name will be found again in a PDF file, its state will be forced. Of course, this option has to be used wisely. You therefore create your own database of the fonts that are the most frequently found.  
Please note that these changes can be stored in the PDF document, and kept from one use of this file to another, or if you send the document to another user.
In this last case, the font name database of the recipient won't be altered.
Once fonts have been marked as music or text, they are processed accordingly by PDFtoMusic.
Music fonts are optically analyzed, character by character, in order to guess the meaning of each of them.
For text fonts, the operation is a bit different. PDFtoMusic uses first the Unicode data from the PDF file. In most of the cases, the result is consistent. However, some PDF files don't provide accurate Unicode data. It's rather easy to realize: recognized text is completely different from the original one.

Here is for instance what you see in PDFtoMusic:

And once the result is loaded in a music notation software:

PDFtoMusic offers a solution to this problem by making "Text font, with optical recognition" editable. Once a font is marked as such, if it appears that there are errors in the default optical recognition (some characters are very close to each other: I and 1, O and 0, etc), you can remap the associated keystroke for any character. To do so, click on the character preview, and then press the key on your keyboard which you would like associated with that particular character symbol. From this point, the result of the recognition is changed.

The characters you modify appear in a different color on the preview.
Amendments to the recognition are stored in a database, so that when a strictly identical character is found later in another document, it will be amended automatically. PDFtoMusic "learns" in order to ease your work.

To input a Unicode character which can't be entered directly from your keyboard, like for instance, Greek or Hebrew, let the command key (Apple key on MacOS, Ctrl key on Windows) depressed, while entering the Unicode value of the character (in hexadecimal).
For instance, Command+0394 will define the capital greek delta.
A summary of Unicode values can be found here:
Finally, some fonts don't include either music symbols or digits and letters, but graphics. Examples of this would be accordion register indicators, guitar chord diagrams, embellishments, etc.
In these cases, you can specify that the font has to be processed as graphics.
The miscellaneous characters of this font will then be considered to be graphics, and exported accordingly in the result file.

Once imported into Harmony Assistant, it gives:

Symbol correction

When moving the mouse pointer over a music symbol, its color changes:


Right-clicking opens the contextual menu related to this object.


In this menu, you can change the object settings. This is very useful, for example, when PDFtoMusic interprets a particular object incorrectly.
The red cross remove the object from the PDFtoMusic processing.
The green cross restore the object initial state.

To select several objects, apply a right click outside any object and define the area. All objects in this area will be selected.
To add several objects to the existing selection, do the same with Alt key pressed.
To remove several objects to the existing selection, do the same with Command key pressed.

You can select all objects from the Edit menu.

All change applied to a selected object will be applied to all selected objects with the same kind.

Staves and systems

A music score is made of several pages. Each page shows staff lines, joined in systems by a vertical line on the left.
There can be therefore several systems in each page.

When a performer doesn't play anything during several bars, the matching staff is often omitted in the system.
PDFtoMusic applies complex algorithms to "follow" staves from one system to another, and bring the parts together.
You can amend this result through "Correction > Staves and systems".

In this mode, the score is displayed in gray, while systems are shown as a blue vertical bar and numbered: S1, S2, etc.

Between each system, a glue tube enables you to merge systems.
Between each staff, a pair of scissors enables you to split the system.

Click the icon to apply the operation.

If you need to apply the same operation to the whole page, the whole document, or to the same place on all pages, right-click the icon and select the operation mode from the contextual menu.

Each part is marked with a letter, possibly followed by its name between brackets.
If you applied a change, the part name is displayed in green.
Clicking the blue arrow in the staff opens the contextual menu for relating the staff to the part:

- Automatic computation:
Cancels an applied change, so that the link between staff and part is computed by PDFtoMusic again.

- Exclude from computation:
The staff will be ignored. It enables you to remove a staff for computation, so that it isn't exported.

- Part list:
Choose in this list the part to which the staff has to be related.

- Create new part:
Creates a new part and relates the staff to it.

If the error you fix has occurred on all pages, right-clicking the staff name opens a contextual menu, enabling to apply the staves arrangement of the current page to all the other pages of the document.

Virtual Singer



Virtual Singer is an additional module for  PDFtoMusic / PDFtoMusic Pro, but also our score editors Melody Assistant or Harmony Assistant and our player Melody Player.
Virtual Singer will make your computer sing: it will generate human voices for staves with lyrics.

Virtual Singer can be configured according to your needs, by modifying timbre, intonation, and kind of voice (man, woman, tenor, soprano, etc.).   Furthermore, several different voices, in different languages, will be able to sing at the same time.

Virtual Singer can also sing "La-La-La", follow the shaped-notes nomenclature (solmization), sing the note names, or even automatically generate Jazz Scat.

The current version of Virtual Singer includes the following languages: Northern French, Southern French, UK English, US English, Latin, Spanish, Italian, Finnish, German, Occitan, Japanese (Romaji), but also Bulgarian, Catalan, Slavon (liturgical slavic language), Czech, Dutch, Esperanto, Basque (Euskadi), Greek, Hebrew, Hungarian, Macedonian, Portuguese, Romani (Gypsy), Romanian, Serbian/Croatian/Bosnian, Turkish and Vietnamese


Virtual Singer installs automatically along new versions of our programs, available on our web site:


During evaluation of the add-on, each time the application is launched, you will only be able to process a certain number of sung parts.  When this number is reached, Virtual Singer becomes "voiceless".
You can then either purchase a license for Virtual Singer (Order submenu) or quit the program and run it again to continue to try Virtual Singer.


Virtual Singer

Voice technical background Generalities

The human voice is amazingly complex, and the Virtual Singer software does not pretend to replace it, but only to approximate it as closely as possible. We will describe here the basic concepts required to better understand how Virtual Singer works.

A human voice can be characterized as follows:

These settings can be adjusted to approximate a given voice as closely as possible.

Singing follows the same rules as speaking. The same fundamental principles can be applied to both of them.

The lungs generate an air stream, which goes through the vocal chords.
Vocal chords are twin infoldings of mucous membrane, positioned at the base of the larynx, which act as a vibrator or "reed".
The vibration frequency is controlled by the singer in order to produce the required note pitch.
This original sound is then shaped by a set of cavities which form the vocal tract (mouth, nasal fossae...).
The singer controls the opening and capacity of these cavities to produce resonances, and in doing so, modifies the sound emitted by the vocal folds.

Speech and Language

Speech is an acoustic way of communication. It is a convention shared by people speaking the same language.
Each language has its own characteristics, and uses a limited number of sounds (about thirty) called "phonemes". These phonemes are then grouped to become a syllable, a word, a sentence...
Some phonemes are common to several languages, because most spoken languages come from the same origin. In addition, the range of possible phonemes is also limited by physical constraints of the vocal tract.


Virtual Singer

Voice technical background

Sung voice synthesis

In voice synthesis, for speech as well as for singing, three main methods can be used:


Virtual Singer

Voice synthesis settings

Virtual Singer palette

When Virtual Singer is installed, the Windows menu gives access to its palette.  The Virtual Singer palette shows the number of singers as well as the language used by each of them.

In the Virtual Singer palette, several objects represent the actions you can perform:

Activate and deactivate Virtual Singer: the colored light in the upper left corner shows the status of Virtual Singer. A click on the bulb toggles this status. When Virtual Singer is activated, staves with lyrics are sung.

When Virtual Singer is activated, a stage is displayed, on which each character represents a sung staff. Since our programs can manage several sung staves within a single document, there may be several characters on the stage.

Character location on the stage shows:

Under each character, the name of the related staff and a flag indicating its language are displayed. You can mix staves of different languages in the same document. We have already seen that is even possible to change languages within a single lyrics staff.

Double-clicking on the character opens the simple settings window. A right-click (Shift+click on the Macintosh) on the character opens a pop-up menu which allows you to:

A click on the flag allows you to change the singer's language.

Tuning the computing mode

To compute a sung staff, Virtual Singer creates an invisible digital audio track, and stores all the  voice data in it.
This computation is quite complex and may take a few tens of seconds.
The computing mode slider lets you select whether this work must be completed before the music starts (0% value) or whether a large part of this job can be performed while music is playing (100%).
This setting depends strongly on your computer. Select its value for optimal performance.

If the number of sung staves is too large or your computer is not fast enough, it won't have time to perform voice computation while the music is playing. You will hear breaks in the sung part. In that case, decrease the value of computing mode, to require that more of it be finished before the music begins to play.

In Harmony/Melody Assistant, when a Shape-note staff is included in a document, a little icon with the sharp symbol appears on the Virtual Singer palette. Click on this symbol to toggle whether accidentals are sung.


Virtual Singer

Voice synthesis settings

Basic settings

Double-clicking on the singer's icon in the Virtual Singer palette opens the pre-defined voice selection window. In this dialog box, you can select another voice from the list and apply an octave shift.

You can also define a new voice and save it in a file.

Send us by e-mail any interesting voices you create, and we'll make them available to other users.

Using "Edit timbre" and "Edit effects" buttons, this window also lets you access the advanced voice settings.

The octave shift lets you change the octave of the sung part without modifying the musical symbols on the staff.

The "Try" button makes the program sing a simple sentence with the selected voice.

The "Play/Stop" button starts to play the frontmost document with the selected voice.

The choir size slider lets you specify that the voice will actually be composed of several choir members singing in unison. A value of 1 means this voice is a soloist. To improve the effect produced by this kind of choir, you can apply a reverberation effect to the staff

Virtual Singer

Editing Phonemes

    Very important: This chapter refers to advanced concepts of digital signal processing. Some knowledge of acoustics and digital signal processing will be needed to make use of it.

We saw earlier that phonemes are considered the basic acoustic elements for the spoken or sung voice (see the chapters on "Voice technical background").
Virtual Singer uses complex algorithms in order to synthesize these phonemes.
This kind of synthesis, called formants synthesis, uses original internal algorithms, inspired mainly by the writings of D. Klatt, as well as other informational sources.
The algorithm has been designed and refined following our own research into the reproduction of the sung voice.

While editing the voice timbre, an "Advanced" button opens the dialog box for defining the individual phonemes. Changes made in this window only modify the current singer's voice. Other voices will remain unchanged.

A few technical details

Question: How does Virtual Singer generate a phoneme?
An excitation digital signal (historically called a "glottal source") is generated, depending on the power and fundamental frequency of the phoneme to be sung. This signal is composed of a parabolic half-period, followed by a silent half-period (glottal stop). The first harmonic (the fundamental frequency),  the second harmonic (twice the fundamental frequency), and the thrid harmonic (triple the fundamental frequency) are then amplified, in order to approximate as nearly as possible the aural rendering of a sung vocal source. This source is then amplified to a greater or lesser degree, according to the voicing value.

Then the processing is divided into two parts:

Cascade processing: a noise, called aspiration noise, is added to the excitation source. This signal is then processed by a serial filter sequence (cascade), each filter corresponding to a formant.

Parallel processing: a noise, called frication noise, is added to the excitation source. The first order derivative of this signal is then processed by a parallel filter set, each filter corresponding to a formant. The amplitude of each formant is processed, in order to increase or decrease the respective influence of each formant in the output signal.

The results of the two processes listed above are then added, and modulated if necessary by a low-frequency (20 Hz) oscillator to simulate a rolling effect (as in Spanish "R"s).

After applying the output gain and treble/bass setting, the output signal is finally complete.

In concrete terms, this algorithm has major implications on how a phoneme is processed:


The basic phonetic element is the phoneme. But we have seen that some complex phonemes, such as diphthongs, can be made up of several successive states.
Because of this, we must define the notion of a fragment, which represents a "static" state within a phoneme. Thus, a phoneme can be made of one or several fragments.

The list on the left of this window displays the complete list of all fragments needed to pronounce any phoneme in any language. Fragments displayed in bold are used by the current language.

Important Note: In this window, you can change the pronunciation of one or several fragments. These changes are only applied to the singer currently being edited. Modifying a fragment in this window will only alter pronunciation for this singer, not the others.

Once a fragment is modified, it is displayed in color in the list. When selecting a modified fragment, it is possible to retore its default values by clicking the Original button below the list.

In the right part of this window, several graphical objects allow you to modify the fragment data.

In the topmost part of the window, a pop-up menu shows the fragment type:
Vowel means this fragment can be stretched when the syllable it is included into is extended in time.
If the syllable does not include any vowels, Virtual Singer will try to stretch transitional vowel fragments.
In the absence of either of those two types, vocalized consonant fragments will be stretched, and then unvocalized consonants.

The fragment duration can be changed through a slider.
This value is the natural time for the fragment. If this fragment is stretched, its duration will be increased.

Note: When a value is changed graphically (through a slider, for example), its digital value appears in a frame on the bottom right of the window.

Static part of a fragment

These are the set of values used to define the static part of the fragment, i.e. the portion that is independent of any transitions to or from adjacent fragments. These parameters can be modified using the large graphical area in the right part of the window.

Formants are displayed as triangles of colored lines. For each formant, the center frequency (in Hertz), Amplitude (dB) and bandwidth (width of the triangle's base, in Hz) can be changed. A set of checkboxes below this graphic allows you to activate or deactivate each formant in the parallel part of the voice generator.

Note: As explained above, even if a formant is deactivated, and is no longer displayed on the graphics, its frequency and bandwidth are still used in the cascade part of the voice generator.
On the right, a set of vertical sliders alows you to change the levels of voicing (av), rolling (Rl), aspiration (asp) and frication (af).

Tip: While editing a formant middle frequency or bandwidth graphically, two vertical lines are displayed. They show the upper and lower bounds for the parameter being modified, for that formant, among all the phonemes in the list. This helps you avoid setting the parameter to too "exotic" a value.

Fragment transition curves

During a spoken or sung part, the transition from one fragment to another is not instantaneous: the next fragment starts to be said before the previous one is completely finished. This smooth transition between fragments is called coarticulation.

For each parameter (formant frequency, amplitude, bandwidth and various levels), the graphic area on the bottom of the window lets you define its transition curve over time. The parameter whose curve is displayed is circled in red in the upper area.

On the transition curve, by convention, the previous value of the parameter is represented by the lowest value on the graph's vertical axis. The static value for the currently selected fragment (selected in the upper graphics) is represented by the highest value on the axis.

Note: this is a schematic display, not directly related to the effective or relative values of the parameter described.

The parameter's transition from its previous value to the current static value is displayed as two segments:
The first segment on the left, whose duration is "stolen" from the previous fragment's time. This segment will make the parameter evolve from the previous fragment's static value to an intermediate value, defined by the two vertical sliders to the left of the curve.
The ratio slider (Ra) lets you select the importance of the previous parameter value relative to that of the current fragment's static value (the value to be reached during the transition).
For example: a 0% ratio sets the intermediate value to the value to be reached.

A 100% ratio sets the intermediate value to the previous parameter value.
A 50% ratio sets the intermediate value to the average of the previous and current values.

The starting offset (Od) allows you to add a fixed amount to the intermediate value.

For example: with a ratio (Ra) of 50%, and an offset (Od) of 100, intermediate value is equal to 100 + the average of the previous and current values.

On the curve, the second segment gives the transition time between the intermediate value and the value to be reached (the static value of this parameter for the current fragment). This time is "stolen" from the current fragment.

Symmetrically, the two segments on the right, with a corresponding pair of sliders, allow you to define the transition from the current static value to the static value of the next fragment.

Thus a transition curve can be defined from the previous fragment's static value, as well as to the next fragment's static value.

Which transition curve segments are used depends on which fragment has a higher priority.  If the current fragment has a higher priority than the previous one, its "transition from previous" segments will be used, instead of the previous fragment's "transition to next" segments. Priority is given by the order of the fragment in the fragment list: the higher in the list, the greater the priority.

If the list only includes three fragments, "a, b, c" in that order, and the syllable to be sung is "babc", the following transitions will be made for each fragment parameter:

Action buttons

These buttons, located in the bottom-right corner of the window, perform several actions:

Try button

You can try the modified fragment by typing a simple sentence in the corresponding frame, then clicking the button. Then, a list of fragments used to pronounce the sentence is displayed. The symbols > and < between the fragment names give the relative priority of each fragment compared to the adjacent ones.
Note: whenever you select a fragment in the fragment list, a sample word for that fragment will be inserted in the text area.
Language pop-up menu
When another language has been selected, fragments used in that language appear in bold in the fragment list.
Copy/Paste buttons
These buttons allow you to copy all of the parameters and transition curves of a fragment, in order to paste them on another fragment.



What is RealSinger?

RealSinger is a Virtual Singer extension that allows you to use more realistic voices to sing lyrics.
The method for generating synthesized voices is different from that used by the regular Virtual Singer.

Virtual Singer's voice generation algorithms, as described in the Technical background chapter, use
completely artificial voices, produced with the Formant synthesis method.

RealSinger algorithms are based on recordings of real human voice elements. These voice samples are then processed to extract the voicing parameters for each phoneme. This unique process enables us to get around the biggest problem with the usual Recorded elements connection method: by keeping only the voicing information, data files for describing and storing a voice are extremely short (usually less than 1 Mb for a full voice in one language), and the voice can be re-synthesized at any pitch without noticeable distortion.

How does it work?

To be able to sing using a new voice, RealSinger needs a recorded sample of each phoneme of a given language, spoken (or sung) by the same speaker (or singer). It then processes all these sound samples and extracts the voicing parameters for each phoneme. The voicing parameter data can then be either embedded in the document file itself, or saved into a separate file to be re-used later in another piece.

To generate a voice following the lyrics and melody, specialized algorithms are used to process pitch changes and to simulate coarticulation (smooth transitions between two consecutive phonemes).

How do I use RealSinger voices?

RealSinger voices are selected in the same way as regular Virtual Singer voices. They are marked by an RS icon in the voice list.

Simply select one of these voices in the voice list to have a staff sung by RealSinger.

For more information about how to have a staff sung by Virtual Singer or RealSinger, please read the appropriate chapters.

You can record your own voice to build a new RealSinger voice file. The following chapters explain how to record, and how to adjust settings for this new voice.

RealSinger provides more realistic sung voices, but the computing time is longer, and the voices can be less versatile (best within a smaller pitch range). Therefore, it is generally best to use a standard Virtual Singer voice while creating a sung piece, and only select and adjust the RealSinger voice at the very end, once the piece is completed.


Your First Real Singer Voice

To learn how Real Singer works, let's quickly create a new Real Singer voice, for Latin songs. Why Latin? This language has few distinct sounds, so you'll be able to record quickly. Also, there are a number of public-domain Latin hymns that you can use to test the voice.

What you need

You must be able to record your own voice to your computer's hard drive. The simplest (not necessarily best) method is to use a microphone of the kind designed to connect directly to your computer's sound card input. However, microphones for professional audio usually must be pre-amplified before your sound card can record the signal. Or, you can use an external recording device, and send its line-out or headphone signal (never the loudspeaker signal!) to your computer's sound card line-in. You can even do the recording with another computer, then transfer the digital audio files. But for now, we will assume that you are recording your live voice directly to your computer.

Let's record!

When you are ready to record, find a quiet area at a quiet time.

- On Melody/Harmony: create a new, very simple document with just one staff. To the left of the staff is a set of icons, shown here. Click the black triangle to open the staff-specific menu, and choose "staff with lyrics." If the Virtual Singer stage does not open automatically,

- On PDFtoMusic / PDFtoMusic Pro: load a PDF file that includes lyrics in latin, e.g. "Ave Maria" in the "PDFtoMusicDemos" folder

Then select the Virtual Singer palette in the "Windows" menu.

The Virtual Singer palette is a stage, shown here in reduced size. Standing on the stage is the picture of your singer, and underneath his picture is a question mark. Click the question mark, and choose "Latin" from the available languages. The question mark changes to an icon. Then double-click the singer. In a few moments, a dialog box appears. Click "Real Singer".

A new dialog box appears. Since you will be recording live, click "record." Be quiet while Real Singer measures the background noise. If it is too loud, try again. After Real Singer measures the backgrund noise, it asks you to say "aah" for several seconds. It is measuring your natural speaking pitch, so that you can listen to sample words at that pitch.

If Real Singer insists that there is too much noise, but you don't know why, possible solutions are discussed in advanced recording techniques. For now, you can bypass thee noise measurement by choosing "set" instead of "record." If you do that, then the next dialog box allows you to manually choose the frequency at which words will be presented. A range of 90-130Hz is comfortable for most men, double that for most women.

The Real Singer recording palette will appear. At the left are a list of words that you must record. Real Singer will offer you the words in order, unless you un-check the "automatic" box. You can save an audio file of each recorded word by checking that option. At top is the current word. If you wish to hear it without recording, click "listen to the word." When you wish to record the word, click "get." Real Singer will play the word, then you will repeat it. Try to imitate what you hear. If your voice is too loud or too soft, get the word again.

If your voice is OK, Real Singer will process the sound and identify the phoneme. The first Latin word is "quid," and Real Singer is looking for a drawn-out "u" sound. At the right is a reduced-scale image showing what Real Singer found for a sample recording. The bright area in the middle is the identified sound. The dark curtains at left and right block off the "q-" and "-id" portions.

The vowel corresponding to English "ee" sound is unusual. In Latin (and in some other languages), Real Singer uses the word "si" for this phoneme. In English, it appears in the word "ease." Many speakers pronounce this vowel with the lips horizontal, as if they are smiling. But good singers produce the vowel with the lips rounded, as they do for other vowels. If you can, record the "ee" sound with rounded, pursed lips, similar to the German u-umlaut. If you record the "ee" sound with a smiling face, it will sound shrill when sung at higher pitches.

Sometimes, Real Singer cannot find the phoneme, or locates it incorrectly. You can move the "curtains" by dragging them with the mouse cursor. You can play back the whole recorded word, or just the selected portion. It is important to choose phonemes carefully - these are the building blocks used to construct all other words!
More information about how to adjust the selection range is found in the "Adjusting phoneme selection range" chapter.
When you are satisfied, click "validate" to add the processed phoneme to the Real Singer voice.

After you validate a word, its appearance on the word list changes. You know which words you have validated, and which ones remain. If you are not using automatic recording, you can choose words in any order, or re-record words that have already been validated. If necessary, you can save incomplete results, and finish the list at some other time. You can even leave some words un-recorded, and Real Singer will use synthesized sound from the Virtual Singer database as substitutes (not recommended). For best sound quality, you should record all of the words, in a single session, so that your own voice is consistent from one word to another. After you have finished recording your voice, close Real Singer to return to the Virtual Singer dialog box.

By default, Virtual Singer asumes that your voice is male, and that you will use it for notes on the Treble staff. Therefore the sound will play one octave lower than the notes are written. If you are female, or if you are going to use this voice on the Bass staff or with Treble-8vb, then set the octave shift to zero. You can also change the singer's stage appearance, if you wish.

While the Virtual Singer dialog box is open, click "Add To List" Give your voice a name and save it. Then move it in the Real Singer Latin voices folder that you created by right-click. This name identifies the voice file, not the character shown on stage. The saved voice file can be used by any singer of the same language, in any other documents. The stage character always has the name of the staff he sings, rather than the name of the voice file he uses.

Click OK to close the Virtual Singer dialog box. You are now back in your music document, with the stage still showing. Save your document, even though it does not have any music.

Using your new Real Singer voice

Open the sample Latin song "Exsultate" in "VirtualSinger/Demos/Latin" subfolder. There are two singers, "Ron Real" and "Vic Virtual." Double-click the image of "Ron" to open Virtual Singer. Ron starts as the default male Virtual Singer, but you will change his voice. In the menu of voices, find the Real Singer voice file that you just created (remember, you put it in the Latin folder). Virtual Singer may tell you that this change will lose the previous setup. Confirm, then click OK to return to the stage.

"Vic" sings with the default male Virtual Singer voice. Leave "Vic" that way, unless you are female and want "Vic" to sing with a female voice. If so, double-click "Vic," and select "Soprano." This voice is not in the Latin folder, but Virtual Singer is multi-lingual. Confirm the change of setup, and click OK to return to the Virtual Singer stage and music.

Save the file (save as) with a different name. Now, play the music. Real Singer must pre-calculate the voices, so there will be a delay. "Ron" and "Vic" will sing together in harmony, with "Ron" the higher voice. You can mute one voice or the other, if you wish.

Most likely, your "Ron" voice is rough. Double-click "Ron" to open Virtual Singer, then click "Edit voice." A new dialog box appears. Under "timbre," choose a value near 30 for each of glottal and opening. Re-play it, and hear the difference in "Ron's" voice.

If you save the music, it will retain the changes made to "Ron" for this music only, without changing the voice file you recorded. If you want the changed voice to be available to other music, within Virtual Singer you can "save preset" to a new voice file. Don't try to use "Ron" to sing English, or any language other than Latin. He doesn't understand it, because you did not record most of the phonemes needed to make words in another language.

When you play your Real Singer voice, you may notice that some phonemes are too loud, or too soft, relative to the others. If a phoneme is not consistent with others, you will hear the same problem each time the phoneme is used. To fix this problem, open the Virtual Singer palette, double-click on the singer, and choose "edit voice," then the "advanced" tab. Choose "edit phonemes." Find the offending phoneme in the list at the left, and select it. On the right you will see several vertical sliding controls. The rightmost two control the phoneme volume at start and peak. Move these up or down, as needed. Play your music again. When you are satisfied with the relative volume of the phonemes, save the voice preset. There are numerous other phoneme adjustments available.

Congratulations on creating your first Real Singer voice! The rest of this Real Singer documentation describes ways to improve your voice recording, ways to improve the precision of the voice fragments, and ways to use Real Singer adjustments to improve the recorded voice.


Adjusting phoneme selection range

After you record each word, the program tries to locate a particular phoneme in this word (the one written in capitals in the sample word), and to remove the rest of the word. Sometimes it succeeds, sometimes not. You can keep the program selection as it is, or find your own. Sometimes your ear is better than the program's mathematical analysis, so it is recommended that you find your own selection range in the recorded sample, even if the computed result appears correct.

Below is a list of the various kinds of phonemes you might be asked to record, and what area the program expects to be selected before validating.


When saying a voiced plosive consonant (G, B, D), just before this consonant is spoken, the mouth shuts completely, and the voice sound is muffled during a short period of time. But this period is not completely silent: while the mouth is closed, air continues to go out from the lungs and the vocal chords continue to vibrate. Air pressure increases in the closed mouth until the lips open again, and the consonant is emitted with a strong power (which is why these phonemes are called plosives).

Obturation is the portion spoken with a closed mouth that you can view on the sound graph: a soft period surrounded by stronger phonemes.

Note for German:

In German, voiced plosive consonants cannot be located at the end of a word: they are said as their unvoiced equivalent (G->K, B->P, D->T).
However, here you will need to pronounce a voiced consonant at the end of the word. To make it easier, imagine that there is a very short vowel after the plosive. For example, if you are asked to record a syllable written "caB", pronounce it as "caB(e)" with a very short ending "e".

Transitional vowels (trans)

Usually these vowels are used only in a short form (never elongated). You will have to pronounce the target word a little bit differently than in "real life," and elongate these vowels. When setting the selection range bounds, be careful to hear only this vowel, not the one that follows.

"Static" vowels

These are called "static" because their phonetic value does not vary over time when pronounced.
You can select only a short portion of the vowel if you wish. Select a section in which the timbre you hear seems correct, and the pitch and power variation is not too significant. The shorter the section you select, the smaller the resulting voice file will be.

Note for German:

In German, there are "long" and "short" versions of vowels. However, in order to enable the software to analyze enough data for "short" vowels, you will have to prolong these vowels at least half a second, even if that is not how they are supposed to sound in German.

Diphthong first part (diphth) - Only in English -

A diphthong is a vowel that changes over time when pronounced. You will have here to prolong the first part of the diphthong and make it sound like a static vowel. Select a portion of this static sound.


Full diphthong (full dipht.)  - Only in English -

Here, you will have to record the full diphthong, spoken quite briefly. Be careful not to drop the volume or pitch down at the end of  the diphthong (imagine you have to say another word just after this one). You must select the whole diphthong. Articulate well but do not prolong the sound too much, or the resulting voice file size will increase...

Stretchable consonants

These consonants can be stretched. (M,N,L,S,F...).  Imitate the sample, and as for the static vowels, select a portion in which the volume stays more or less constant.

Plosive unvoiced consonants (T,P,K)

These consonants are preceded by a short period of "glottal stop," a silent phase. Emphasize the consonant itself and make it sound louder than it should be in normal speech. Then adjust the selection range so that it starts just after the glottal stop, and ends after the consonant and its aspiration noise are finished.

Plosive voiced consonants (D,B,G)

These consonants are preceded by a short period of "obturation" (see above). Emphasize the consonant itself and make it sound louder that it should be in normal speech. Then adjust the selection range so that it starts just after the glottal stop, and ends after the consonant and its aspiration noise are finished. See the special note for German users in the "Obturation" topic.

Aspiration (hhh)

This is the sound when the singer recovers his breath. Breathe in quite quickly (less than 1 second) without any lip sound: open your mouth before starting recording, then breathe in as if you were surprised. Adjust the selection range so that it includes the whole sound (with a brief period of silence after the sound).


Factors to be considered when

recording for Real Singer

Noise factors

Environmental noise

If a passing noise interferes with your recording, simply re-record it. If you have companions, suggest that they go elsewhere, since their small movements may escape your attention but still be heard in the recording. Yes, your friend sitting behind you is giggling while you are trying to record...

A.C. hum

Depending on your country, alternating current (AC) hum has a frequency of 60Hz or 50Hz, with overtones throughout the vocal range, particularly at 180Hz (150Hz). At right is the spectrum of AC hum from a noisy setup. It is very important to reduce AC hum, since it is difficult to remove this noise without distorting your voice.

If you use a laptop computer, the simplest way to reduce AC hum is to use battery power, and have no peripheral devices connected. If you do use peripherals, the cables should be disconnected at the computer when power is off, not left dangling from the computer.

When a preamplifier (or tape deck) and a computer are connected, and when both of them use AC power, the amount of hum depends on how the power cords are plugged in. The loudest hum is produced when the two devices are plugged into different wall sockets. If one device has an AC auxiliary outlet, plug the second device into it, rather than to the wall. Or, plug both devices into a single extension cord. If the power plugs are not polarized (that is, if they can be inserted into the outlet with prongs reversed), try reversing the prongs.

Some microphones will pick up a lot of AC hum when you touch them. If that happens, mount the mike on an insulating stand, instead of holding it. If you do not have a mike stand, try taping the mike to a wooden stick, held vertical by taping it to the back of a chair. Pay careful attention to this. Just because a microphone can be held in the hand, does not mean that it should be held. If you use a headset microphone, see if AC hum is reduced when you remove the headset.

Be sure that your microphone cable does not run near any power cords. There may be power lines underneath your floor, so try moving the microphone cable. The same applies to the cord between computer and preamp or tape deck, if you are using one. It is especially important to stay away from motor-driven devices, including ceiling fans.

Machine sounds

If you see a noise spectrum like the one above, but the fundamental frequency of your AC is not the first peak, then the source of noise is probably a motor-driven appliance. Machine sounds are common. You have learned to ignore your refrigerator, heating, ventilation, computer fans, and ticking clocks. But if they are present, they will be included in your voice recording. Consider turning off machines - but don't forget to turn them back on again! If you have a lot of noise distributed evenly across the spectrum, it may be caused by air rushing through a ventilation system.

System noise

Some noise is caused by the electrical properties of your system. If this noise is small, Real Singer can analyze it and reduce its effect. But if the system noise is too large, you will have to try a different recording method.

If your computer's sound card is poor, it will detect electrical noise from the surrounding circuitry and include it in your recording. This is especially true if you are using a microphone connected directly to the computer's microphone input. If you have eliminated all other possible noise sources and still have too much unexplained noise, this may be the culprit. Try recording your voice to a tape deck, or using a pre-amplifier, so that you can feed the preamp line-out to your computer's sound card line-in, instead of to the microphone jack. Remember that external recording equipment usually requires a different kind of microphone than the kind used directly by computers.

If you are using a tape deck, it is better to use high-bias or metal tapes and noise reduction. Do not use automatic gain control. Do not use a microphone "built in" to the recorder.

Sound quality factors


The human voice contains important frequency components across a broad range. The fundamental pitch of sung notes is below 500Hz (even lower for the male voice), with important overtones at higher frequencies. The range around 2-6KHz contains frequencies that add color and definition to the voice, especially during some consonants and transitions.

Be sure that your microphone has a smooth frequency response across this spectrum. If the mike is normally sensitive only to low frequencies, but has an artificial boost for the highest frequencies, then your recorded voice will sound too bright. Some computer mikes intended for speech recognition (conversion of words to text) may have such an artificial frequency response. But as long as the mike responds adequately across the vocal range, it is not necessary to have a level (flat) frequency response, since Real Singer includes an equalizer.

Saturation and clipping

Saturation and clipping occur when an input signal is too large. This can occur at the microphone, or at any stage of signal processing.

If your voice is too loud, the microphone will distort the sound, even if the electrical output from the mike is within the acceptable range. Computer microphones often have a low dynamic range, meaning that there is not much difference between the softest sounds they can detect above the noise, and the loudest sounds they can accept without distortion. When recording to Real Singer, it is important to keep your voice at uniform loudness. This is especially true if you are using a computer microphone.

Professional audio microphones have a much greater range of loudness that they can accept without distortion. But the range of electrical signals produced is also large. This kind of microphone is used with a preamplifier (or tape deck, acting as preamp). Be sure to pay attention to the VU or other signal amplitude meter. It is OK to briefly exceed a limit if the sound is in an unimportant part of a word, far from the phoneme that you are trying to validate.

Do not use automatic gain control (AGC) for recording to Real Singer. The distortions introduced by AGC are likely to be greater than the distortions removed. It is better to move away from the microphone, or manually adjust volume controls. Portable tape recorders, and office-style voice recorders, usually use AGC. Avoid using these devices, if you can.

If you are transferring a signal into your computer from a preamp or tape deck, be sure to use the correct jacks. Never take a signal from a jack intended to directly drive loudspeakers. The best connection is line-out to line-in.

If you are using an audio editor to apply digital filters to a pre-recorded waveform, be sure that the filter does not clip your sound.

Special problems

Difficult sounds

Some consonants are difficult to record, because they are soft and create a lot of breath wind. In English, these are f, h, s, and th (thin). You will need to place your mouth close to the microphone, but not allow the breath wind to touch it. It helps to feel the air stream coming from your mouth when you make these sounds, to ensure that the mike is correctly placed.

Some other consonants are difficult to record, because they are abrupt. In English, these are b, d, hard g (go), k, and p. These sounds have a moment of high intensity that quickly tapers to a short sound. If spoken too loudly, the intense part will saturate or clip. If spoken too softly, the tapered part will not be detected. Or, if you naturally speak these consonants softly, Real Singer may decide that your voice is "too loud" based on the part of the recorded word leading up to the consonant. Resist the temptation to speak these in an un-natural manner, to "help" Real Singer find them. If you do that, Real Singer will find an un-natural sound!

If you are having difficulty producing a satisfactory recording of these consonants, or if you would generally like to change what Real Singer hears from you, then pre-record your voice and use an audio editor. You can reduce the amplitude of an unnecessary part of a word that is "too loud," so that a necessary, softer part can be accepted. But it is usually not advisable to edit the volume in the portion of sound that contains the desired phoneme, because that will interfere with noise-removal processing.

Using an audio editor

An audio editor is a program that will open an audio file, change its contents, and export the result to a new audio file. One such program is the free Audacity (Windows or Macintosh) available from In addition to opening and exporting WAV files, it can open and export Vorbis OGG files. These files can be used by Real Singer in place of a live voice.

With an audio editor, you can: (1) Import a lengthy recording or several words, and slice it into individual words. (2) Adjust the volume or equalization. (3) Inspect sounds for the presence of sudden noise events. (4) Apply special effects (not recommended for Real Singer).

With an audio editor, you can help find sources of noise by looking at noise amplitude and spectra. The most valuable use is to inspect the recording waveforms for the presence of saturation and clipping. For this reason, it is a good idea to pre-test your method of recording, inspect its results with an audio editor, and make any necessary changes to your setup. Then Real Singer will have good quality sound to use for your voice.

Saturation occurs when an increase in sound power produces less than the proportional increase in recorded signal power. Saturation is often desirable; it is certainly better than clipping. But in Real Singer, it is better to avoid saturation, because the recorded tone will be used in soft and loud passages. If you look at sample recordings of your voice with an audio editor, and see that the recorded amplitude is always about the same during both loud and soft parts of your speech, then you may have saturation. (Or, you may be a master at keeping your voice at an even level!) Try recording at lower volume, or move the microphone slightly farther from your mouth. Be sure that automatic gain control is not in use. Avoid saturation in, or near, any part of the word that will be used for the phoneme.

At right are some images (at reduced size) from an audio editor. The top image shows a waveform that has been properly recorded. Even though Virtual Singer plays a sample word with very uniform amplitude, the live human voice varies in amplitude. These irregularities can be seen in the envelope of the waveform.

The second image is the same sound, recorded with saturation. Notice how the irregularities of the envelope have been smoothed. Examining the spectra would show that certain frequencies are more prominent in the the waveform with saturation than in the unsaturated wave.

The third image shows clipping, in this case caused by too large an electrical signal at the sound card input. Notice how the envelope has been flattened (flattening may be symmetrical or asymmetrical).

The fourth image also shows clipping, even though the recorded waveform has lower amplitude than before. In this case, the clipping occurred at the microphone, because the sound was too loud. The electrical signal was reduced by the sound card volume control. However, once a wave is clipped, it cannot be un-clipped.

At left is a composite image of two spectra, for the same word recorded by two different microphones. Areas of concern are marked with an asterisk. One of the microphones (purple spectrum) shows excessive response in the second overtone (third harmonic), which is one characteristic of saturation. Also, that microphone shows excessive response in the high frequency range - probably due to artificial enhancement - which makes the sound bright and harsh. This microphone was intended for computer speech recognition.

The other microphone was a pre-amplified dynamic type, normally used for audio recording. It had a more satisfactory sound quality (green spectrum).


Adjusting phonemes

Once all the phonemes have been recorded, you can play the sample tune.

Some phonemes will almost certainly not be what you expected, and will need adjustment.

How to find a bad phoneme

Adjusting a phoneme

Several problems can make a phoneme sound wrong.

If the phoneme timbre (tone or sound) does not match the expected result, we recommend that you record it again, by selecting the phoneme in the list on the left, then clicking Record.

If the problem comes from the phoneme power (volume), i.e. the phoneme is ttoo soft or too loud in the sample word, there is no need to record it again. You can adjust the starting and ending power using the Vst (volume start) and VMa (volume maximum) sliders on the left of the phoneme spectrum display.

Other adjustments can also be performed, but they require a deeper knowledge of the internal operation of RealSinger.  Therefore, they are reserved to experienced users:

Two sliders control the coarticulation time:
Dtd is the transition duration from the previous phoneme
Dtf is the transition duration to the next phoneme


Technical background

Note: This page is only a brief overview of the methods used by RealSinger to produce a voice.
It is not necessary to read this chapter to use RealSinger. This chapter is indended to answer technical questions some users might have about the internal algorithms, and is not needed to use the product.


To synthesize a realistic singing voice, the first idea that comes to the mind of the programmer is to use a collection of recorded phonemes to generate the voice.

Three problems quickly become apparent:

  1. The algorithm used must be able to generate the phoneme at any pitch (fundamental frequency). Recording every phoneme at all possible pitches is not feasible, because it would lead to a long and complex recording process, as well as huge voice files.
  2. The algorithm must be able to elongate, or stretch, the phoneme to any duration.
  3. The algorithm must be able to generate a smooth transition from one phoneme to another, in order to simulate the coarticulation phenomenon (the next phoneme starts to be heard before the current one is completely terminated).
A solution can be found for each of these problems in the published computer literature.

Efficient algorithms have been developed to solve problems 1 and 2. They process the recorded sample's digital data directly, allowing the programmer to change its frequency (pitch) as well as its duration. These algorithms are used in most popular sound editors to change the pitch and speed of a sound file independently. They are also used successfully in speech synthesis, because speech frequency (pitch) variations are quite small.
However, in the case of the sung voice, these algorithms cannot be used, because they are not efficient when the pitch shift is too large. The result is not "wrong" as such, but the voice is distorted, just as when playing a magnetic tape at too high a speed (chipmunk voice).

For problem 3, a common solution is to record not only the individual phonemes of a language, but all possible combinations of two or three phonemes (diphonemes/triphonemes). This system stores the coarticulation effect and makes the synthesized voice more realistic. However, here again, the recording process is quite difficult and extensive, sometimes requiring several hours of work for the speaker or singer. The resulting voice file is often quite large (several megabytes).

RealSinger uses original algorithms to solve all three of these problems at the same time, by manipulating frequency spectra.
Some speech synthesizers have tried to use voice frequency spectra to generate voice in the past.
However, this method proved to be difficult to implement, because recreating a signal from a processed spectrum using an inverse Fast Fourier Transform (IFFT) requires that the "phase" values be reajusted properly.  If they are not properly adjusted, consecutive pieces of signal won't join and an unwanted background noise will be heard.

Voice spectrum

In speech or song, the glottal source waveform (the sound produced by vocal chords when excited by the air stream from the lungs) is a combination of harmonics (frequency multiples of the fundamental frequency f0).

On a power/frequency graph, this glottal source sound looks like a comb, with each tooth of the comb located at a frequency that is a multiple of the fundamental f0:

When the voice pitch increases, the fundamental frequency f0 shifts to the right (higher frequency), and the frequency offset between two consecutive harmonics increases too, to remain equal to f0.

In passing through the vocal tract, some frequencies are enhanced by cavity resonances, and others are softened. The result is that certain harmonics are loud, and others are softer. This vocal tract spectrum depends on the phoneme being said or sung, and is more or less unchanged when frequency (pitch) increases or decreases.
The convolution of these two spectra (glottal source and vocal tract) gives the resulting spectrum, in which the listener can determine both the phoneme (what is said) and the pitch (sung note).

RealSinger basics

The aim of RealSinger is, for each phoneme of a given language, to apply a deconvolution to the recorded signal in order to separate the glottal source and vocal tract spectra. Then it stores only the vocal tract spectrum, and will apply a generated glottal source to this spectrum to simulate the original recorded phoneme being sung at any pitch.

Learning process

This algorithm enables RealSinger to store only a few values for each phoneme, which means very short voice files (less than 40 Kb once compressed).

Generating the voice

This algorithm simulates coarticulation effects. Therefore it is not necessary to record the whole set of diphonemes or triphonemes. Only pure phonemes are required.


Myriad HQ

Myriad HQ is an additional module for our music products. It brings an enhanced audio quality, new option for digital output, and high-quality sounds, generated by external plug-ins (VSTi) or by "MyrSynth-Guitar", our pinched string instrument generator

Trial vs registered version

The Myriad HQ module can be used free of charge in trial mode. All its features are then functional, but the module disables itself after some time in the session.
To continue trying it, you just have to quit the program then run it again.

If you are convinced by the tryout, you can then purchase a license for 30 euros (or US$37). You'll receive a personal registration code that unlocks the Myriad HQ limitations.

To disable Myriad HQ use "Configuration>Myriad HQ>Enabled"

Control Panel

To activate or deactivate each component of Myriad HQ, open its palette in the "Windows" menu.
In this palette, a set of buttons will let you switch each component on or off:

- The "General" button activate or deactivate all the components at once

Digital High-Definition
Myriad HQ logo design by Gaël Martin

To store a sound digitally, the computer gets the value of air pressure on the microphone membrane, thousands of times per seconds. This list of values (samples) makes the digital sound, that can be stored, processed by mathematical operations, or replayed by the reverse process.

Quality of a digital sound is therefore defined by two values:

- Its sample rate, which is the number of samples per second

- The sample "depth", in bits, which is the accuracy of  each value, the number of different values each sample can take

The "Audio CD" quality is: 44100 Hz sample rate (44100 samples per second) in 16 bits, i.e. 2^16 = 65536 possible values.
Our products manage this quality without the Myriad HQ module.

With the Myriad HQ module, it's possible to use up to:

- 96000 Hz sample rate, more that the double, for a finer mesh, thus better high-pitched sounds, a better sound dynamic, and a decrease of noise ratio.

- 32 bits deep samples, 65000 times more accurate than an audio CD, to avoid metallic tones (aliasing) and get a better accuracy in quite sounds

These quality improvements can be applied to:

- The digital output, on which you listen to your score

- Uncompressed digital export (WAV) to process your audio data in another application

- Digital input from microphone or line in

- Digital tracks in your document, that can be mixed together of with regular music staves

Please be careful however, data in top quality are 4.35 times bigger than classic data


Myriad HQ

Multichannel output
Myriad HQ logo design by Gaël Martin

Audio output channels represent the loudspeaker on which sound is played.

A single loudspeaker (one channel) is a mono output

Two loudspeakers (two channels) is a stereo output. The sound, different on the right and on the left, enables the listener to locate the sound position from right to left

More channels can make the sound surround the listener, or make enhance basses
In Myriad HQ, you can select up to 8 channels for the sound output.

This is set up through "Configuration > Digital output configuration"

In instrument settings, in addition to the stereo position, a "fader" button appears, letting you select the instrument position on the front/back axis.

Here are the diagrams for the most common channel configuration. Please note that Myriad HQ goes even further, by enabling to define a custom set of loudspeaker, thus a setup that doesn't appear in this list.

1 channel

1.0 : Mono

2 channels

2.0: Stereo

3 channels

2.1 : Stereo + subwoofer

Some digital effects can be applied to your score sound, just before its data are sent to the loudspeakers, the headphone or exported as a digital audio file.

These digital effects can be set up from "Score > Global digital effects", and are improved by the Myriad HD module.

Currently, a multi-band equalizer will let you finely adjust the final sound output, by amplifying or dampening some frequency ranges.

Myrsynth - Guitar

Myriad HQ logo design by Gaël Martin

What is it?

Myrsynth-Guitar is part of the Myriad HQ module. It's a physical synthesis of pinched string instruments.

Unlike a sound base, in which recordings of a real instrument playing notes at different pitches are reassembled to play the score, physical synthesis calculate the sound data depending on the instrument physical parameters and the performer technique.

A digital equivalent of the physical instrument (body, strings) is built in memory, then the virtual strings are pinched and the vibrations transmitted to the miscellaneous elements through mathematic formulas. The result of these calculations is then picked up by virtual microphones, and the sound can be heard.

What instruments, what playing technique?

Myrsynth-Guitar can simulate most of the instruments with pinched single-strings (no double strings) : Guitar, bass, luth, banjo, ukulele, etc, mounted with metal and/or nylon strings.

Most of the playing techniques are managed, including natural & artificial harmonics, hammering, slap, slide & bend, muted notes, etc
The whole range of flamenco "golpe" can also be played (hit on the instrument body with the thumb, fingers or palm)

Myrsynth-Guitar automatically computes the strumming direction, and can slightly arpeggiate chords. It can also put stress on rythm beat, simulate the sliding of fingers on strings, or let the string continue sounding after the end of the written note, for an even more stunning realism.

Instrument and play mode selection

In the instrument selection box ("Staves > Edit related instrument" menu option) the "MyrSynth virtual instrument" type can  be selected in the pop-up menu.
When selected, you then get two lists.

On the left, the list of available MyrSynth instruments. They are sorted by category, and by sub-category for guitars.
In real life, it would be several instruments on their stand, you can pick one to play.
The "Tuning" button under the list lets you choose another tuning for this instrument.
During playback, if some notes cannot be played (for example because out of the instrument pitch range), they will play a "golpe" (body hit) instead.

On the right, the play mode list. This will be the way this instrument is played. You can select the plectrum, decide whether you play softly or heavily, follow exactly what is written or play with more emotion, etc.
In a general way, "clean" play modes follow the written score : note duration and power, struck chords, no finger sliding noise. On the opposite, "noisy" play modes" are more humanised, but less faithful to the score

Automatic selection when importing and loading

The program can, when a score is imported or loaded, automatically select the more appropriate MyrSynth instrument, when it exists.
This can be set up through "Options > Myriad HQ > MyrSynth setup

In the list on the left "standard" instruments that can be used in the score
Tick "Display all" to see them all, otherwise you'll only see those for which the matching with MyrSynth has already been defined.

On the right, the Myrsynth instrument selector, as well as its play mode.

This match will be applied, and Myrsynth instruments will replace "standard" ones, according to the selected option at the bottom of the box:
Cette correspondance pourra ętre prise en compte, et des instruments MyrSynth sélectionnés
"Imports" are files in a foreign format (MIDI, Karaoke, Finale, MusicXML...)
"Old files" are score files that have been saved with a version of Melody/Harmony prior to the first version of MyrSynth

Special case: forced matching of the output type

In the global setup, "Load" section, output kind of all instruments of a loaded file can be forced.
In particular, the user can decide that all instruments of a loaded score will automatically play to digital output, even if they were set as using another kind of output (e.g. MIDI) by the author
What must be done, in this case, when an instrument in the loaded score uses a MyrSynth instrument?
Will it be kept as is by the program, or changed to a standard (sound base) instrument?

This depends on the settings in the MyrSynth setup box (see previous chapter). If the automatic choice for Myrsynth has been selected for any kind of file, then the MyrSynth instruments will be kept. Otherwise, they will be changed by an instrument that uses a sound base.

Frequently Asked Questions

Here are some frequently asked questions, along with their answers:

-> PDFtoMusic displays a score but says that the document doesn't include any exploitable music data. Why?
Some PDF files embed only a single picture for the whole score, instead of  a collection of simple graphic objects. This kind of PDF file has probably been generated from a scanned paper sheet. PDFtoMusic can't extract and process elementary graphical items in such cases, and reports that such a document cannot be processed.

-> How to know whether a PDF file can be processed by PDFtoMusic?
The simplest way is to ask PDFtoMusic to load it. It will then tell you.
Otherwise, open it with Acrobat Reader (or equivalent) and do "Select All". If the PDF file contains exploitable data, the selection range will be fragmented. If the PDF file contains only a scanned picture that can't be processed either the selection range will be empty, or the whole score will be selected as a single block.

-> Why are certain characters specific to a language not recognized?
You must verify that the unicode information is correct.
Open the PDF with Adobe Acrobat Reader or equivalent.
Select the relevant text, copy.
Paste in a text editor.
If the characters are incorrects, the unicode data in this PDF file is not valid.

-> A password is asked when I load or export the PDF, why ?
The author of the PDF file had protected his work, contact him to got the password.

File formats

PDFtoMusic manages several file formats. Here is an overview of each of them.

Adobe PDF format (.pdf)

This format has been designed by Adobe, PDF standing for "Portable Document Format". It eases the exchange and distribution of any document. It can store any kind of graphical objects, from text to pictures.
It's the groundwork of PDFtoMusic.

PDFtoMusic reads and processes this kind of document, as long as its data contain vector graphics.

MusicXML format (.xml)

Designed by Recordare, this format is about to become the exchange file format for music scores. Based on XML, a text descriptive format, it is now managed by an increasing number of music programs.
In order to open PDFtoMusic to as many people as possible, it has been naturally chosen as the groundwork format for the Pro version of PDFtoMusic.

PDFtoMusic Pro writes this kind of document.

This format is not managed by PDFtoMusic, in its "non Pro" version.

You can use Melody Player to view and listen to list of files of this kind.

MusicXML compressed format (.mxl)

It is a packed version of the MusicXML format. In fact, this kind of file can be obtained by compressing a MusicXML file as a Zip, then renaming the result file from .zip to .mxl
In the same way, the original MusicXML file can be extracted from the .mxl by renaming it to .zip then unpacking it with any utility that supports this format (for instance, the original unzip program)
Because MusicXML is a descriptive text of the score, these files can be quite large. In order to save bandwidth, either when such files are sent by e-mail or put on a Website, using a .mxl can be useful.

PDFtoMusic Pro writes this kind of document.

This format is not managed by PDFtoMusic, in its "non Pro" version.

You can use Melody Player to view and listen to list of files of this kind.

Myr format (.myr)

It's a Myriad proprietary format, managed by Melody Assistant and Harmony Assistant.
Music-related information is stored as musical objects.

PDFtoMusic writes this kind of document.

You can use Melody Player to view and listen to list of files of this kind.

MyrWeb format (.myrweb.html)

With this format, anybody can view and hear your score, without having to install anything on their computer or tablet beforehand.

A MyrWeb file can be sent by e-mail, or included directly in a Website without needing any special technical skill.

The dead simple score sharing format par excellence.

PDFtoMusic Pro writes this kind of document.

This format is not managed by PDFtoMusic, in its "non Pro" version.

Mid format (.mid)

This format, based on the MIDI exchange standard between electronic music devices (keyboards, synthesizers, expanders, etc) contains a description of the notes that constitute the music pieces, as well as basic information about the score. However, details about the piece graphical appearance, its page layout, note appearance or ornaments are not stored. Albeit very incomplete, and until the use of MusicXML broadens, it remains the standard exchange format for almost all music programs.

Wav format (.wav)

It's a binary audio format. It contains stereo digital audio data. This format is lossless, which means that it can be loaded, changed and saved as many times as needed, without any loss in quality (contrary to MP3 or OGG, for instance).

Initially designed for PC,
it is now managed by almost any sound editor or player, or CD burning software.
When PDFtoMusic generates this kind of file, it uses the digital sound database that has been installed on your computer. A better quality will be obtained when using the GOLD base.

PDFtoMusic Pro writes this kind of document.

This format is not managed by PDFtoMusic, in its "non Pro" version.

Structure of your user folder

The user folder contains files that have been created by PDFtoMusic. It is highly recommended to perform backup copies of this folder at regular intervals.

This folder is located in your user document folder, in the "Myriad Documents/PDFtoMusic" subfolder.

The subfolders are:

"Correction" : If you asked for the corrections not to be stored in the PDF document itself, the changes you applied to the documents will be stored here. There will be one correction file for each edited PDF.

"Export": When the result from an imported PDF file is automatically exported, it is stored by default in this folder. You can change this location from the general preferences, "Export" section.

"OCRCorrection": When you amend the result of the character optical recognition, databases are created in this subfolder

Keyboard shortcuts

Beyond keyboard shortcuts for menu options, some keyboard keys trigger actions:

Spacebar: starts and stops music playback
Down arrow: switches to next page
Up arrow: switches to previous page
Esc: cancels processing of the current file
