Independent attributes for each soundpack and keyboard #17
Description
Proposal
Since CalcuPiano will support multiple keyboard, see #15, users may apply different soundpacks or attributes to different keyboards.
Meanwhile, Soundpacks might vary in volume, pitch or play rate. Users may want to adjust them to a comfortable level.
Basic Support
- Allow adjustment of volume, pitch, play rate for each soundpack. #18
- Users can multiplicatively adjust them again for each keyboard.
