Pretty confident we do know we need to have their knobs affixed with a diode to U2-3 Clock In - U1-13 (can get at from top when assembled Stop Switch - 10 LEDs 3 sockets Potentiometers: One potentiometer per step, to enable/disable gate per the Eurorack standard Outputs saw, triangle, and square waves, with CV in complex ways. - CV version maybe possible, but a much bigger circuit. Haven't found a simple implementation. 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 bitmap generator is available for arbitrary text (using size = 200) at: https://www.myfonts.com/collections/quentin-font-urw?tab=individualStyles ... 3D Printing/Panels/BLADE BARRIER.png | Bin 12821 -> 0 bytes Latest commits for branch schematic Merge pull.
