Wild PWM using an external LFO. Use any CV LFO source you have, this was recorded using the LFO OUT from a MOOG WERKSTATT-01. Feeling a bit moody as the show Debris has been canceled. Even if it's a genre you don't like, the soundtrack and sound design is worth the hours.
First 15 seconds of this patch are dry, and it's already wild, but Hybrid Reverb in Ableton 11 (Textures + Tides algorithm) pushes it a few light years.
