I bought a rack a few months ago..... mine hasn't been turned on in a looong time.. I havent started learning it yet- first thing I plan on doing when I get home from school next week for summer is to organize all my drum sounds and map some kits. I'm not planning on using its sequencer, some people like it, others say it sucks.. but I plan on sequencing on the computer (if I can find a good user friendly sequencing program).
