I want to use the Tyros 2 as midi sound module for Biab, it works but when I play back a midi file from my computer, the Tyros 2 plays all the parts correctly excepts the drums, that it plays back always with a piano sound. I think that the T2 automatically resets the drum parts to sound '00' or something like that. The same thing happen when I use Biab and the T2.

I have tried all the 'MIDI preset setups' on the T2, but there's no change, the drum parts don't play back correctly. Anyone messed with a similar setup? Maybe it's some of that Sysex stuff that I have never understood or cared about
