Kick drum schematic Add pulldown resistors for reset debounce cap; formatting 2c2abd8837 checkpoint before getting really weird with WireIt A couple more GND-stitch vias Undo converting GND to GND_JMP and fix everything that broke 3583986e89 Finished PCB, passes all passable DRCs Footprint selection, some PCB layout choices 4d8e233e93 Add CV in to pause the sequence. Seven-segment display. 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 much bigger circuit. Haven't found a simple implementation. Can be passed in as parameter to eurorackPanel threeUHeight = 133.35; //overall 3u height panelOuterHeight =128.5; panelInnerHeight = 110; //rail clearance = ~11.675mm, top and bottom boards.
