2 Ch Low Pass Gate / Mixer

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.

-DAMP parameter programs how low pass gate responds to falling control transient, continuously variable from long, slow and ringing to short, fast and muted

-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)

-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

Revision 2 adds audio side-chain compression and expands CV generation and processing capabilities.
