I use midi files for the same purpose and would also love to see this feature in Mobile Sheets. However, I can appreciate Mike's response in that it definitely isn't a trivial undertaking. The only thing I would add is that I think Mike could consider using fluidsynth as the standard cross-platform synthesizer piece. But I think that's actually the easiest piece of the whole puzzle. Trying to create a player that layers on top of the midi file and fluidsynth - definitely not trivial.
