More info
Quad is a fully analog four channel crossfader, scanner and four channel VCA. At audio rates it works as a wave shaper, while combining audio rate signals and control voltage signals creates additive synth tones. With DC coupled inputs, it is capable of crossfading between control voltages. All of the functions work in stereo or mono for unique crossfading effects and complex stereo crossmodulations.
