My wife gave me this for Christmas. I know it's early, but we are going to visit to relatives and car spave is at a premium so we exchanged gifts. I have no idea how to use it. So far, I've been having fun just playing keyboard through the PC. It has eight knobs, a slider, and some wheel things that can be programmed as well. I think I actually need to read instrucions for once! This is thing is very fun so far though.
