Alpha pots: barely enough to attach knob 01bb4964a6 Add CV in complex ways. - CV version maybe possible, but a much bigger circuit. Haven't found a simple manual EG ~$7 in parts, depending mainly on whether 8+6 pins + hardware fits on shaek board or similar size perf. MiniADSR derived from Schmitz's FEitW maybe simpler?
