Get A Classic Piece Of West Coast Synthesis With The Make Noise Optomix 2-Channel Low Pass Gate Module

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.


  • 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 modDemix and MATHS


Panel Controls

  • CHannel 1 Signal INput: Direct-coupled signal input capable of accepting audio or control signals. Range of up to 10Vpp
  • CHannel 1 DAMP CV INput: CV input for the CHannel's DAMPing parameter, now capable of accepting audio or control signals. Normalized to +8V so that with nothing patched, the CHannel 1 DAMP Combo Pot operates as a manual control for the parameter. Range 0V-8V
  • CHannel 1 CONTROL INput: Direct coupled, highly-sensitive CV input for the CHannel's vactrol VCA. Normalized to +8V so that with nothing patched, the CHannel 1 CONTROL Combo Pot operates as a level control for the Offset. Range 0V-8V
  • CHannel 1 DAMPCombo Pot: Unipolar attenuator for DAMP CV INput. With nothing patched to the DAMP CV INput, operates as a manual control for the DAMP parameter
  • CHannel 1 Combo Pot: Unipolar attenuator for CONTROL Signal INput. With nothing patched to the CHannel 1 Control
  • CHannel 1 Signal OUT: Output of the signal applied to the CHannel 2 input, as processed by the LPG. 10Vpp (depending upon settings and source material)
  • CHannel 1 STRIKE INput: Gate INput for striking or plucking the vactrol. Expects 8V Gate
  • CHannel 2 Signal INput: Direct-coupled signal input capable of accepting audio or control signals. Range of up to 10Vpp
  • CHannel 2 Control Signal INput: Direct-coupled, highly-sensitive CV input for CHannel 2's vactrol VCA. Normalized to +8V so that with nothing patched, the Channel 2 Combo pot operates as a manual control for the Offset. Range 0V-8V
  • CHannel 2 DAMP CV INput: INput for CHannel 2's DAMP parameter, now capable of receiving audio or control signals. Normalized to +8V so that with nothing patched, the CHannel 2 DAMP Combo Pot operates as a manual control for the parameter. Range 0V-8V
  • CHAnnel 2 DAMPCombo Pot: Unipolar attenuator for CHannel 2 DAMP CV INput. With nothing patched to the CHannel 2 DAMP CV INput, operates as a manual control for the parameter
  • CHannel 2 CONTROL Combo Pot: Unipolar attenuator for CHannel 2 CONTROL Signal INput. With nothing patched to the CHannel 2 Control Signal INput, operates as a manual level control for the Offset
  • CHannel 2 Signal OUTput: Direct-coupled OUTput of the Signal applied to the CHannel 2 INput, as processed by the LPG. 10Vpp (depending upon gate settings and source material)
  • CHannel 2 STRIKE INput: Gate INput for striking or plucking the CHannel 2 CONTROL vactrol. Expects 8V Gate
  • AUXiliary INput: Direct-coupled signal input to the SUM circuit, allowing for the chaining of multiple Optomix and modDemix units to create larger mixes. Capable of accepting audio or control signals up to 10Vpp
  • SUM OUT: The SUM or mix of all signals processed by the OPTOMIX is output at this jack. 10Vpp (depending upon settings and source material)
