Moog Werkstatt → Ekdahl Moisturizer → compressor
The Left expression pedal → cutoff frequency of Moisturizer's filter.
The Right expression (blue) → amount (amp) of Werkstatt's LFO out going to Moisturizer's LFO input.
Moisturizer's LFO out → Werkstatt's LFO input (cross-modulated LFOs for patterns).
The compressor pedal is very custom one with 1 input and 2 outs (L and R channels correspondingly): both with EQ but the second one (R) is more aggressive, with distortion and diode clipping.
OP-1 was overdubbed later.
