Optional 2x Toggle Switches, 2pin: - reset in - CV in to pause the sequence. Seven-segment display. 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 bottom; these are some setup variables... You probably won't need to test spell names on narrower widths. The first two groups should be possible, too * See manual step (featuring debouncing!), sequencer cascading, basic glide (for portamento), attack decay sustain release envelope generator synth module. Layout and panel are Kosmo format. * [Schematic](Docs/precadsr.pdf) * PCB layout: [front](Docs/precadsr_layout_front.pdf), [back](Docs/precadsr_layout_back.pdf) * [BOM](Docs/precadsr_bom.md) * [Build notes](Docs/build.md) How to use 7.5mm holes, not 6mm - alpha pots - 9.8mm, +2mm rotary - 11.5mm, +3.5mm -- biggest by far, maybe 12.6mm?
