Bubblesound VCA4P Quad VCA Eurorack Module 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.
