Live Software Loopers with multiple independent phrases

[karlbarton@comcast.net]

Hi All,

I am looking for a software solution for a PowerBook G4 running OSX 
10.4.11 in live performance that can have three (or more) separate phrases 
(i.e., chorus, verse, refrain) and be able to switch back and forth 
between the phrases after recording and overdubbing along with an undo 
feature for each phrase. 

I do have access to Intel Macs and Windows desktops, but really wanted a 
laptop solution, and the PowerBook G4 Mac is what I have. I am familiar 
with the comparison chart of Software Looping Programs by Krispen Hartung, 
but am having trouble determining the possibility of separate, independent 
phrases using the chart.

Thanks for your help!

Karl
