Checking out Servo, a unique new module from ADDAC Systems. It can turn knobs or trim pots on a modular, synth, pedal, mixer, or anything else that’s small and cylindrical and that lacks a cv input! Perfect for when your hands are busy doing other things, or when you want slow LFO-style modulation, or super-precise stepped adjustments.
I'm using it here to control the envelope decay of a Moog Subharmonicon. I'd be interested to hear what others might use it for.
