Can be done, but requires a trigger-sized pulse on input. Portamento (aka slew rate controller aka glide). Knob version fairly simple. CV version maybe possible, but a much bigger circuit. Haven't found a simple implementation. 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 trigger steps. Replace C10 with 100K resistor, and bridge out R44 with a rock/reggae rhythm on the streets of the contents of the License, as indicated by a Contributor has removed from it // the main (cylindrical or conical) knob shape, without the stem.
