Looking at the Live 4 features page marked "On the spot Sound Design" they say ..."Warp Markers in conjunction with the sample offset envelope can produce entirely new and exotic loops".
How the hell do they get that "buzz/roll" sound?? I've tried everything with no luck. The audio file in question is sdloop warp scramble.mp3
I'm sure you can't do it by drawing little pink rectangles. Can anyone give me a hint?
