One of my fav tricks on my Cocolase was to do something similar. I would ‘flip’ at audio rate, and have the gain all the way up. While doing this you manually control the speed knob, and you have, in effect, is a crazy wavetable synth where the audio-rate ‘flipping’ is the ‘pitch’ and the speed knob controls the timbre by deciding what the waveshape would be.
This track is primarily that “synth” sound, feeding one channel of the cocolase into the other one for delay/looping.
