BackOTA, an expensive and rare chip these days ($3/ea on amazon, maybe fakes) VCA MK's VCA Probably a straightforward build: one op-amp, four transistors and some example modules main 5a4e89eea6 Add position for resistor between coarse and +12V, value unknown .. Fireball VCO saw wave core.circuitjs.txt Latest commits for branch feature/seq_chaining Add CV (and knob) controlled glide to schematic 16c50fa0a8 Add pulldown resistors for reset debounce cap; formatting checkpoint before trying to add picture 9f9f6acf76 Add notes about UX component wiring 2x Sockets, all three pins need wires: glide in (j16/j17 // cv switch // steps: slider, led, switch (sw1-sw10, rv1-rv10 // mounting holes 47.1mm, distance of mounting holes distance 25mm 9-pin D-Sub connector horizontal angled 90deg THT male pitch 2.77x2.84mm pin-PCB-offset 7.699999999999999mm mounting-holes-distance 33.3mm mounting-hole-offset 33.3mm 15-pin D-Sub connector horizontal angled 90deg THT female pitch 2.29x1.98mm mounting holes to PCB edge 9.12mm, see https://disti-assets.s3.amazonaws.com/tonar/files/datasheets/16730.pdf 25-pin D-Sub connector, horizontal/angled (90 deg), THT-mount, male, pitch 2.77x2.84mm, pin-PCB-offset 14.56mm, distance of mounting holes 63.5mm, distance of mounting holes 25mm, distance of mounting holes to 5mm + unplated, and revises jack footprint a3181ad06b Add correct footprints to fireball Add correct footprints to fireball 3c7abf2196 Move LED resistors next to transistors to wide
