I'm pretty new to using the Elektron Octatrack's MIDI sequencer but I did a bit of an experiment here, sending an arpeggio and clock to my rig.
The main voice is a Mutable Instruments Tides, with envelopes trigged by both the OT and Zularic Repetitor.
The voice was run through Magneto, and then sampled back into the Octatrack on a Pickup machine, looping it. Loops of loops, and loops of those loops therein.
