I have a Sound Blaster 16, CT1740 which when I insert it into the computer, changes the instrument mapping for the wave-table of the RAP-10. No drivers loaded or anything, just taking the card out fixes the problem, but it only seems to affect DOS. MIDI-songs played in Windows seems to be routed correctly, so I was wondering, what's going on? The CT1740 MIDI-port is set to 300, while the RAP-10 gets to keep its original 330.
