The Optomix music synthesizer module
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.
Max Depth: 24mm
25mA @ -12V
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
Direct coupled, process audio or control signals
Utilizes 4 vactrols
Pairs well with modDemix and MATHS
