I was having problems getting the MT32 to work with Spellcasting 101, and found others with the same problem here. I didn't find a solution here (or on the web,) but in desperation (ok frustrated anger,) did some experimentation. I finally got it working, but the old threads were to old. So, for anyone interested here is the very easy fix.

Edit the Legend.bat file (or your config file if you are like me and bypass the bat file.) Remove the "2 330" part of the command line so that it reads (in my case,) "S101 SVGA XMOUSE BLASTER 7 220 MT32" and after a MT32 notice screen the game loads and plays MT32 just fine.
