I need a 1 rack space unit which can do the echo loop ON THE FLY just like the Denon X1500 mixer like in this video:

I am wondering if the Lexicon Jamman can do it but I don't think so, I think the Jamman has to record a sample first so that won't work if that is the case. Anyone know of any unit which can do this please?
