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? SR2511 series are 11.43? Maybe more?
