  • Regular price $ 225.00

Based on the VCA from the storied Polyfusion Modular, the VCA4p is an up-to-date VCA with a vintage approach. Like most VCAs in classic analogue synths from the 1970’s this module uses OTA chips in lieu of a contemporary alternative. This is a choice in support of sonic character, as opposed to realising a “perfect” circuit.


This module can be used as 4 separate VCAs, in either exponential or linear modes, or as a voltage controlled mixer, via the MIX output at the bottom of the VCA4p. A jumper on the rear board allows for combinations of straight VCA duties and/or VC mixing duties, depending on the musician’s needs.
