In a previous chapter (microtonal
adjustment) we saw it is possible to change pitch for a given note
to make it match another frequency than the 12 steps equally tempered
Please refer to this chapter to know how microtonal adjustment values can be calculated in order to match the required frequencies.
By combining this feature with rules set, it becomes possible to build a staff that plays automatically in another tuning system than 12ET.
Using a predefined template in alternate tuning
Some document templates in alternate tuning are provided in the software.
When starting a new document through File>New, open the Alternate tuning template folder and select a template.
Notes inserted in score will play in the alternate tuning system you selected.
Using a predefined rule set for alternate tuning
If you wish to apply an alternate tuning system to an already written
staff, you can load the rule set that defines this tuning. To do this,
select "Edit rules" from the staff menu then the staff you want the alternate
tuning to be applied to.
Note : If you want several staves in a same document to be alternate tuned, you will have to repeat this procedure for each of these staves.
Then, click "Load set" and open the "Alternate tunings" folder located in the Melody/Harmony folder on your hard disk.
Select the rule set file (.lex) you want to apply and OK.
From now, all notes in this staff will be played according to the new
Building a custom rule set for alternate tuning
Imagine you want all thirds in a staff to be pitch-shifted by 16 hundredth
of semitone from the 12ET scale.
Here is what you need to do :
Playing an alternate tuned staff
The same restrictions we saw in microtonal adjustment
also apply to alternate tuning : in Midi output, only write alternate tuned
"solo" staves (no chords) and be careful no other staff uses the same Midi
