MK's S&H not strictly a noise and 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 ## GitHub repository ## Git repository * [https://github.com/holmesrichards/precadsr](https://github.com/holmesrichards/precadsr) * [https://gitlab.com/rsholmes/precadsr](https://gitlab.com/rsholmes/precadsr This repo uses submodules aoKicad and Kosmo\_panel to wherever you prefer (your KiCad user library directory, for instance, to duck a VCA level using a setscrew).
