From the project

Eurorack polyphonic controller

Quango is a combined MIDI interface, VCA and envelope for controlling four voice polyphonic Eurorack Modular Oscillators. Polyphonic signal interconnections are made via RJ-45 cables (ie Ethernet cables).

Quango can control two VCOs simultaneously, supplying 1V/Octave pitch information and then shaping the returned audio using 8 ADSR envelopes controlling VCAs for each voice.
