Play Flexi loops clip style, trigger them with keys. The loops will switch immediately to the triggered loop, still playing in time.
Select 8 clips/loops that run in time with the sequencer with C2 through G2.
Use Loop length (an LFO running to sync) to adjust each clips length.
To extend with more Flexi clips, uncompact and add more layers (duplicate) and adjust the shapers and CV sequencers as needed.
