The Zoxnoxious project uses a Raspberry Pi to interface between analog voice cards and a VCV Rack frontend. The user of the synthesizer can add up to six Zoxnoxious hardware voice to the synth which will be controlled from VCV Rack software. The voice cards focus on old school 1980s analog IC chips with functions such as oscillators, filters, amplifiers. With VCV Rack as the frontend, these analog chips can be manipulated in many ways.
