i wouldn't quote me on this but i beleive GM midi and roland mt-32 are two diffrent midi standards. i don't think a mt-32 can do general midi well (or at all) and you would need something like a Roland SC-55 to do general midi, though i'm pretty sure the sc-55 can emulate mt-32
here, i found this thread about this very topic here when i was trying to figure all this out. http://www.gamehourz.com/Roland-soun...ict232728.html
neat link. i still like the sound from the MT-32 best
