Diode Operator Station VCF Filter - 18HP


The Diode Operator Station VCF is an analog filter based on the Steiner Diode array. You patch a 'sound' module like a VCO or Noise Generator into one of the input jacks. You then use the big knob to filter out frequencies and become a star.

There is an on board VCA internally connected to the final output. The vca is turned fully counter clockwise for normal operation. This will allow sound to pass 100%. When you would like to use the module for regular mono synth action you turn the vca knob until the sound is 'closed' or gated. Simply patch an envelope generator to the 'cv' input and turn up the knob. The envelope generator will open the vca. There is also an ouput line level rca jack that you can use to record straight to your daw in mono.
