Front panel (only) for 10 cm wide Kosmo format synthsizer module with two control voltage quantizer units, both the same. To complete a build get this and the dac/ino board (available here separately). Rotary switches enable selection of any of up to 12 scales in each of up to 6 banks, up to 72 scales total. There's a second CV that can transpose the quantized first CV (normaled to +5V, with an attenuator), a gate input and switch to disable/enable quantization either manually or via a gate, a trigger input that allows using it as a quantized (or not) sample and hold. Use this with any 0-5V control voltage source to produce notes in equal temperament, major or minor scales, just intonation, well temperament, microtones, or practically any scale you can imagine! Red FR4 front panel only; dac/ino PCB, components, and assembly required.
