A few news about MyrScript

This week, we are still working on MyrScript.
You can download the new version of the MyrScript Programmer Manual in PDF format at http://www.myriad-online.com/myrscriptbeta/myrscriptmanual.pdf
This manual has been enhanced and partially proof-read.
- The Interface Composer module is now working well. We extended the number of possible item types in dialog boxes by adding sliders, user items (the script programmer can use them to manage any item type that is not provided by default), and lists.
- Instrument object type has been completed, and now a script can build its own digital sound. As a matter of example, we wrote a sample script that builds "analog" drums sounds by mathematical calculation.
- Tablature object type is about to be fully implemented.
- File function set has been completed. It enables a script to perform any file I/O operation, and also to manage standard pathes (to get, for example, the default folder where user settings are located...)
Comments are welcome !

Hello Olivier,
This is really exciting!
Just one question: Will there be an addSymbol function? I don't see it yet in the manual.
Thanks,
Grandpa

Yes, such a function exists.
See : Staff.InsertRest, Staff.InsertNote and Staff.OverlayNote
A problem in the manual building procedure has removed comments about these methods. Here is the explanation :
Staff.InsertRest(...)
Inserts a rest just after the symbol that precedes the given time position.
If there is already a symbol at the given time position, the new rest is inserted in chord with this symbol.
If the time position lies between two symbols, the rest will be inserted after the whole duration of the previous symbol, and will shift the next symbol to the right of the score.
In fact, InsertRest mimics the way a rest is inserted when you click between two notes on a score, using the rest insert tool.
PARAMETERS: Number : Time position
Number : Rest duration
RETURN: Symbol : Added note
or nil if the note could not been added.
EXAMPLE:
note1=myStaff.InsertNote(0,DURATION_QUARTER,5*12) -- Insert a quarter C at the beginning of the staff
if note1~=nil then
note2=myStaff.InsertRest(note1.Time+DURATION_EIGHTH,DURATION_EIGHTH)
end
-- will result in : Time position 0 : A quarter C
-- Time position DURATION_QUARTER : An eighth rest
Staff.InsertNote(...)
Inserts a new note just after the symbol that precedes the given time position.
If there is already a symbol at the given time position, the new note is inserted in chord with this symbol
If the time position lies between two symbols, the symbol will be inserted after the whole duration of the previous one, and will shift the next symbol to the right of the score.
In fact, InsertNote mimics the way a symbol is inserted when you click between two notes on a score, using the note insert tool.
PARAMETERS: Number : Time position
Number : Symbol duration
Following parameter is optional
Number : Note pitch
RETURN: Symbol : Added note
or nil if the note could not been added.
EXAMPLE:
note1=myStaff.InsertNote(0,DURATION_QUARTER,5*12) -- Insert a quarter C at the beginning of the staff
if note1~=nil then
note2=myStaff.InsertNote(note1.Time+DURATION_EIGHTH,DURATION_EIGHTH,5*12 +2)
end
-- will result in : Time position 0 : A quarter C
-- Time position DURATION_QUARTER : An eighth D
Staff.OverlayNote(...)
Adds a new note at the required time position, without moving notes around.
As a result, the inserted note will be placed at the exact time position you specified, and some rests might have been added in chord with the previous note in order not to move other notes in the staff.
Special consideration : only notes (not rests) can be overlayed
In the provided example below, a new note will be added
Parameters : Number : Time position
Number : Symbol duration
Following parameter is optional
Number : Note pitch
RETURN: Symbol : Added note
or nil if the note could not been added.
EXAMPLE:
note1=myStaff.InsertNote(0,DURATION_QUARTER,5*12) -- Insert a quarter C at the beginning of the staff
if note1~=nil then
note2=myStaff.OverlayNote(note1.Time+DURATION_EIGHTH,DURATION_EIGHTH,5*1 2+2)
end
-- will result in : Time position 0 : A quarter C in chord with an eighth rest
-- Time position DURATION_EIGHTH : An eighth D

Olivier,
Thanks for the quick response.
I sometimes like work with notes that have strange durations like 5 8ths (2.5 qtrs). Could the note length constrants include something like that? Say, are the constants additive? Could I say something like my note.duration = HALF_NOTE + EIGHTH_NOTE
Also, will there be a function to change the duration of a note?
I'd like to avoid tieing notes together if that's possible.
Also, are there any functions for manipulating bars. Say I wanted to change bar #3 to be 5/8 and set the beaming a certain way. How would I do that?
Also, is there a way to select a certain bar rather than deriving where the bar would be?
Thanks,
Grandpa

The duration can be fixed at any value. Some constants are predefined. For example a whole note equal 161280 time units.
If you want you can use a note duration of 161281...

Time signature changes are not yet implemented.

I don't understand your question, could you provide a sample ?
Best regards

Hello Didier,
Are the functions to select/delete/insert another bar at some bar in the score (say bar 20).?
Thanks,
Grandpa

Yes, see page 66. TimeBeginSelection and TimeEndSelection values allow you to select any part of a score.
Then the method CopySelection and PasteSelection (page 71) allow you to copy it in the same score or in another score.
Best regards

Hi Didier,
It would be great if you had a function in the script that gave you the beginning time of a bar, facilitating say select a bar or bars far into a complex score (w/ time sig. + tempo changes).
Thanks,
Fred

Hi,
See Score.TimeToBar(...) and Score.BarToTime(...) (page 68 ) which do the job, I think.
Best regards
