VCA4p Four-Channel VCA

Bubblesound VCA4p

The Bubblesound Instruments VCA4p is an adapted version of the VCA found in the Polyfusion modular and is perfect for polyphonic amplification and mixing of control voltage or audio signals. The four channels feature gain adjustment knob, CV input, and switch to select between linear and logarithmic CV response. It can be used as four separate VCAs and also features a dedicated mix output for voltage controlled mixing. Jumpers on the back of the module select which of the four channels are sent to the mixer for custom mixing configurations. While not a perfect VCA by today’s standards, the VCA4p is a characterful and fun VCA and mixer.
