This filter module is a classic state variable filter. Two signal inputs for different signal levels control the "drive" of the module. Compared to the wasp filter this filter has a significant self resonance and also a very quick response to cutofffrequency changes. Module power consumption: 2 mA Inputs IN H - main audio signal IN L - optional additional audio signal which will be mixed together with the main signal at a lower level before going through the filter CV 1 - control voltage for cutoff frequency, this will affect all three filter curves CV 2 - control voltage for cutoff frequency, this will also affect all three filter curves Outputs LP - low pass filter output BP - band pass filter output HP - high pass filter output BUS CV - this sits below the input jacks on the left side and will output CV pitch from a connected MIDI device BUS CTRL - this sits below the input jacks on the left side and will output the MIDI control message from a connected MIDI device (CH1 - CC20) Controls FREQ Knob - cuttoff frequency CV 1 Knob - control voltage attenuator RESONANCE Knob Patch Suggestions Here's a patch for a low pass gate: Any signal -> SVFILTER (IN L) SVFILTER (LP) -> VCA (IN1) ENV (OUT) -> SVFILTER (CV1) ENV (OUT) -> VCA (CV1)
