This is probably an old topic, but now I'm interested. I want to funnel all of my midi files through my PSR2000, but sometimes I get that darn Yamaha drum track (and others) problem. Things aren't where they belong and everything sounds like a piano. How can I fix this permanently? I want to abandon my SC88 as my midi source and go exclusively with the 2k. And, does downloading the 2k instr. file from Cakewalk help?
