I'm finding Notation Composer a fascinating tool to experiment with. My interest is downloading piano rolls captured on MIDI and printing sheet music to play on piano. These MIDI captures are unaligned relative to beat with complicated rhythms, making it impossible for Composer to correctly interpret. I'm OK with that. However, the printed sheet has lost alignment between right and left hand note placement that strike simultaneously in the performance, and at times ordering between LH and RH notes. They are aligned to the new as-noted interpreted rhythm which is incorrect. I know it's incorrect because when I snap to attack as-notated, playback stutters and jumps. What is needed under the piano roll menu is "Snap as-noted to performed attack." The performance is correct. What I'm asking is the ability to snap the note positions to the performed attack positions. Keep the note rhythm values, just line them up to the performed attack. It's what I expect to see on the music because I've heard the song, and I want to play it that way. The as-noted rhythms are quite complicated for humans to read (so it's OK that they are imperfect), but we pianists heavily depend on simultaneous note alignment, and ordering when we play, and those need to be right. This one feature would greatly improve piano playing usability of the generated sheets.
