BackDominant hand plays Low. Could also be made "round", using the current 12-position rotary switches with 4 unused pins if supplying power, but not some kind of odd LFO. * 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 the two clockwise-most pins, looking from below. Clock rate goes down when resistance goes up, opposite to expectation.
