Got BASSMIDI installed, finally figured out how to add more than one soundfont to it.

I've been trying to use it with SCummVM. I've editted some of the games to use that driver, but as soon as I fire up a game (say, MI2), it immediately takes me to a debug screen. Hitting ESC promptly closes the game out.

Any ideas on what I'm doing wrong? Surely there's *some way* of getting this to work.
