So you're patching your synthesizer, deep into a groove, and you run into a wall: not enough VCAs. We've all been there. Whether adding a voice, bringing in a modulation source, modulating the modulators, or panning signals around in stereo or quadraphonic sound, every new patch idea seems like it calls for just one more voltage-controlled amplifier.
This module gives you four. Four clean general-purpose VCA channels based on the Alfa AS3360 chip, with normalling between the channels to make stereo patching convenient. It's easy to build cross-fade and panning patches with the separate inverting and non-inverting control voltages on each channel. The global mix output works for combining voices, and there are two sets of two-channel sum and difference outputs, allowing the Quad VCA to serve as a mid-side encoder and decoder. The normally two-quadrant VCA channels can even be used in pairs for two four-quadrant ("ring mod") multipliers. With so many ways to use it, the Quad VCA could be the only VCA module needed in a small portable rack, or the heart of a complex patch in a large installation.
North Coast's Quad VCA is available as a pre-built 20HP Eurorack module or a DIY kit. Remove the limits.
