Optomix
The Optomix music synthesizer module 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.
Revision 2 adds audio side-chain compression and expands CV generation and processing capabilities.

features
-
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)
-
Normalization 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
-
Part of a decentralized mix console integrated throughout the system along with X-PAN, modDemix, Dynamix, and RxMx
-
Direct coupled, process audio or control signals
-
Utilizes 4 vactrols
- Pairs well with modDemix and MATHS
