Interconnects between middle and bottom boards. Final work on PCB 7f9b624c8e tweaks layout with input from sam # drumkit All-in-one module with lots of analog drum voices; based heavily on Moritz Klein's work, but with buffering between (some) stages. Needs a _big_ knob, these are actually 2p6t, which means only six different step counts are available until the replacement arrives - Wiring SW15 (once/stop) and cascade out is easier done via skywiring; only one side //calculated x value of exact middle of panel after deducting left/right sub-panels slider_center = (width_mm - left_panel_width - right_panel_width)/2 + left_panel_width; panel(width); // lower h-rib reinforcer ## Photos ### Photos ## Documentation: ### Documentation: * [Schematic](Docs/precadsr.pdf) * PCB layout: front, back How to use 7.5mm holes, not 6mm alpha pots - 9.8mm, +2mm - rotary - 11.5mm, +3.5mm -- biggest by far, maybe 12.6mm?
