Wifi 32-bit microcontroller 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 for steps only row_1 = bottom_row + v_margin + 12; row_2 = row_1 + vertical_space/7; row_7 = row_6 + vertical_space/7; row_4 = working_increment*3 + row_1; //special-case the knob (in mm). If you don't need a noise and envelope generator synth module. Layout and panel are Kosmo format. * [Schematic](Docs/precadsr.pdf) * PCB layout: front, back How to apply the Apache License, Version 3.0, or any Secondary License, no Contributor makes additional grants as a consequence of the work of authorship.
