I have the Casio CTK-2000, and it does like 5 drum kits. I can do everything on the video (This is rock and roll... too funny!!!!!!!!!!!!!!!!!!!),
but 2 things... if you play too fast, like simulating a drum roll, the keys will start missing. I'm not sure where, but somewhere there's a point where it's just
too fast, if you know what I mean. The other thing is, unless he's an amazing key player to begin with, I don't see how he did it so cleanly. The keys don't correspond to a scale like a piano, and it's weird to leard it. It's MUCH easier laying down each individual drum track and mixing it later in Acid.
Personally, I think it's faked, but I agree... who cares, that was classic!!!
