I am not a specialist on sound libraries etc so I'll try to explain my problem in the simplest way I can. I have managed to import the microtonal tuning I wanted to use (from scala) and it sounds fine in Aria player. However, because of the additional number of notes required, half of the notes now appear to be outside the instrument's range and thus do not produce any sound.
Is there any solution to that? I have tried to edit the .sfz files with not great success:
In the "region" area, I replaced the lowest valued "key=..." with a "lokey=... hikey=...". It did work, but the sounds produced for the additional notes are somewhat not good (although they would normally be inside the original instrument's range).
I'd like to know if there is anything else I can do or indeed if you have any suggestions on editing the .sfz files.
