Make Noise Optomix - Dual Low Pass Gate

The Optomix music synthesizer is a two channel Low Pass Gate, providing simultaneous voltage control over amplitude and frequency content of a signal. It is in essence, a Voltage Controlled Filter Amplifier (VCFA) that has an extremely organic response to control signals. The Low Pass Gate is a classic West Coast synthesis circuit.

This latest revision adds audio side-chain compression and expands CV generation and processing capabilities


•           Damp circuit updated to accept audio as well as CV allows for patching side-chain compression

•           STRIKE INput allows use of Gate signal to trigger Low Pass Gate circuit, 'plucking' or 'striking' the vactrol

•           DAMP and STRIKE parameters combine to allow for easy programming of percussive sounds (sharp Attack w / Voltage Controlled Decay)

•           Normalisation of a positive offset to the Channel inputs allows for level-shifting of CV, Envelope Generator and even subtle non-symmetrical clipping of signals

•           Summing stage with an AUXiliary IN allows for chaining of multiple units creating larger mixes

•           Direct coupled, process audio or control signals

•           Utilises 4 vactrols

•           Pairs well with modDemix and MATHS
