We could generate CV some other way for now, such as: * https://www.mouser.com/ProductDetail/Bourns/PTL30-15O0-105A2?qs=fV9UsjselOEqdQiKFAm%2Fog%3D%3D (A1M, orange LED, 30mm travel, 15mm shaft * https://www.mouser.com/ProductDetail/Bourns/PTL30-15R0-103B1?qs=X8nz4ozed5glbMOCRmYKzw%3D%3D (B10K, red LED, 30mm travel, 15mm shaft ** https://www.digikey.com/en/products/detail/bourns-inc/PTL30-15R0-103B1/3781301 (red B10K) and https://www.digikey.com/en/products/detail/bourns-inc/PTL30-15O0-105A2/7314942 (orange A1M) The first two groups should be possible, too * Manual trigger See manual step (featuring debouncing!), sequencer cascading, basic glide (for portamento), attack decay sustain release envelope generator synth module.
