SVFILTER (STATE VARIABLE)

View Product Page

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)
