This is all interesting to me, as well. I've got an M-AUDIO 88 controller, the BTBuilder game that I'm developing art for now has OGG support and I'm the only "musician" (and I use that term lightly) available. I was considering using Med SS to do the music, as I don't have any soft synths, nor any mixing software. I haven't done *ANY* sort of music since the early/mid 90's.
Any help would be appreciated, as well.
