Can be done, but requires a lot of wiring and increases risk of noise on power rails. Things best left to external modules: - CV-controlled CV offset module - add a voltage to another voltage. Useful here for pitching up from a base. Update readme Potentiometers: One potentiometer per step, to set number of pins: 14; pin pitch: 5.00mm; Vertical; threaded flange; footprint includes mount.
