Optomix is a dual-channel low-pass gate module. The Optomix gives you simultaneous voltage-control over the amplitude and frequency content of a signal. With a natural and organic response to control signals, this module's circuitry is a classic West Coast synthesis circuit with the ability to provide audio side-chain compression, expanded CV generation, and a collection of of various processing capabilities. The Optomix is also equipped with Strike inputs for each channel, allowing you to use a Gate signal to trigger the low-pass gate circuit, resulting in a striking or plucking of the vactrol. The Optomix features direct-coupled inputs, able to process both audio or control signals. This module is a flexible unit perfect for your Make Noise modular system.
