Optimizing MIDI Scores for Limited-Key Instruments

[uoodin]

• Context of Use

  • I mainly play the game "Sky," which features a 15-key piano.

• Issue Encountered

  • In using it, I've noticed that many MIDI-imported scores don't perform well on a 15-key range because there are only two octaves plus a C6. Many MIDI notes get dropped.

• Request for Advice

  • Could the author advise if there's any room for optimization for playing with 15 keys?

I am aware of this problem at very early stage of the project.
However, I can't find much information about optimizing a score for a range-limited situation on the web.
The current algorithm "moves the entire score up and down" and finds the best pitch offset so the dropped notes is minimal.

I have come up ways to optimize but not implemented simply because I'm currently too busy to maintain this project:

• Run this algorithm on each track, but make sure the order of tracks' average pitch stay same (the bass track should not higher than rythm track)
• Run this algorithm on sections/segments of the score, not the entire score. this probably works for score that have low pitch sects and high pitch sects.

Also I don't know this project even have English users, maybe someday I could add l10n support...
