Kim, Thanks for the reminder on this (below - undo function). I'm now regularly using the EDP during weekly gigs and am very pleased with even my basic use to solo over chord changes. Btw, I'm having trouble learning to record different loops on the fly, then switch them during performance (Ex. Take Five - chorus then a bridge). I'll look the switch-quant function discussion up again and get back in touch if I still can't figure it out. Thanks again...
