I've been trying to figure out how to play with myself.... uh.... I mean... I want to play the drums and record it, and then play back my own drumming somehow like they do on guitar with loopers, and then play the guitar along with my own drumming. I'm guessing that I' have to record the drums into an MP3 format, then play that back from a laptop into a PA system, and then play the guitar with real amps. I've also thought about buying multiple loopers and connecting them to different amps so that I could walk around the room, play each part one at a time and setting each looper in motion. By the time I got all the way around the room, all the loopers would (in theory) be playing along with each other.
