drag a jack (or a knAck's center hole) to another jack to patch · drag a header to move a module · drag empty canvas to pan

A knAck is a knob and a jack sharing one spot — turn the ring for its base value, plug a cable into the center hole for CV, flip the little +/− to invert how hard the CV pushes it. Cable color follows the destination's job, not the source module: audio-in half, modulation-in half, gate-in half — the same oscillator cable turns from violet to cyan the moment you move its far end from the Filter's IN jack to the VCA's LEVEL knAck.
