The Gainbrain is a flexible module that can be used as a video-rate VCA, two-input crossfader, or an analog voltage multiplier optimised for LZX signal levels. It has controls for both bipolar manual offset and bipolar scaling of the CV control voltage for maximum control.

The Gainbrain can also be used to produce waveshaping effects and ringmod-like effects by multiplying two different waveforms together.
