Details

This is a voltage controlled filter module which utilizes analog switches to adjust the frequency of the filter. The module features two state-variable filter sections which share a common frequency control, these can be used in series for heavier filtering or in parallel to work with stereo sound sources.  It has the following controls and I/O:

Knobs

  • Frequency – Controls the frequency of both filters.
  • Frequency Modulation – Attenuates a modulating cv input for the frequency control.
  • Resonance 1 – Controls the amount of emphasis on the selected frequency of the filter for channel 1.
  • Resonance 2 – Same, but for channel 2.

Inputs

  • Clock – An oscillator should be input here, it will be used as the clock for the analog switches in the circuit. Pulse waveforms should not be used.
  • CV – This is the input for the frequency modulation CV.
  • Input 1 – Signal input for channel 1
  • Input 2 – Signal input for channel 2

Outputs

  • Low pass 1
  • Band pass 1
  • High pass 1
  • Low pass 2
  • Band pass 2
  • High pass 2

The board features PC mounted pots for less wiring, and mounting holes for flexibility in panel layout. There are Eurorack and MOTM power connectors.
