Yeah the Kp3 would definitely do that, I used to use it for the same thing but then did way to much with it, as a simple looper it'll have 4 banks and you can then layer things on top.. Could be good for opening up your creativeness. Have you seen the RC-505? I know Dub FX uses a looper set up and I'm pretty sure he operates outside of normal bpm constraints, i.e it doesn't detect/use bpm to create bars you manually loop in/out. I just did a google and found him doing an introduction to a new piece of kit, I don't think it's what he uses though.. DubFX playing live
