So I'm getting ready to make the plunge (thinking Boss RC-20), but I wonder if there's one function that I'd *love* that it won't do: multiple loops on top of one another that you can switch on and off. . . . . like a DJ. I know Ableton Live does this on a laptop, but it seems like it would be too tough to actually use live. We'd have to prerecord the loops, which makes the performance less exciting. Anybody doing this successfully, and if so, what are you doing? Thanks --JES PS --I'm not a solo bassist, but in a duo.
