I use an Electrix repeater [for live looping]. It works...it's unstable and the MIDI implementation was written by a sped. I think it's Canadian but that may be a coincidence. I've been through all sorts, the original jam man was great but clicked on the loop if you didn't get it just right, something I am familiar with. As I said in another answer I have an RC50 but haven't fired it up yet. On paper it looks great.
