    • With external CV control such as sequencers and keyboards


    Corner frequency of filter. summed with CV F input and expression input. Frequency range without external control 8HZ - 6kHZ


    Quality factor or resonance control . Before noon for softer equalisation. Aggressive past noon. self oscillates past 3 0'clock. summed with CV Q input.


    Negative and positive gain of bandpass filter section allows for notch or boost of selected frequency (FREQ) .


    Frequency response can be tilted around the center frequency. At one extreme, a low-pass response; at the other, high-pass. At noon, the response is flat. In between these points , various degrees of flat. In between these points, various degrees of shelving.


    unity gain is around 2 0'clock for a flat frequency response.
