The VCA4p based on the VCA from the classic Polyfusion modular synth. Unlike many modern VCAs this one centers around an OTA chip, like most VCAs from the 1970’s. While this VCA may not be perfect by today’s standards, it’s those imperfections that give the VCA4p it’s character and warmth. This VCA is meant to be used as 4 separate VCAs, a voltage controlled mixer or a combination of both. By using the jumpers on the back the user is able to configure this VCA to meet their specific needs.

Rev2 Changes:

A classic returns better than ever. The Gain pot has its own CV path now
so its curve is consistent regardless of the CV setting. The switch
choosing between Linear and Exponential response has been replaced with
a pot. This allows much more flexibility in how each channel of the
VCA4p sounds. And finally it is now very skiff friendly and ready for
the thinnest of cases.
