  • Regular price $215.00

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
