There may be things in the apple developer beta area that would be of interest, but a lot of it is under NDA.

Are you trying to re-create music sequences with these files? Or are you looking to play a sampler as a way of triggering sound effects? Or both?

well, I mean pure in the sense that with GarageBand and other similar programs you typically compose songs by sequencing samples, and I was thinking that there should be a format which just consists of that data, the samples and the times they should be played.
