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 Pairs well with modDemix modDemix and MATHS
