Multimode State Variable Filter

20 HP Eurorack module

A multimode state-variable filter with dedicated 2-pole low-pass and high-pass outputs plus a switchable band-pass or notch output.

Features

Dedicated 2-pole low-pass and high-pass outputs.
A switchable band-pass or notch output.
Optional +6 dB input boost and clipping circuit.
Pitch input tracks 1 V/oct accurately over more than four octaves.
FM CV input with attenuverter.
At maximum resonance it can self-oscillate as a low-distortion sine-wave oscillator from 2 Hz to 20 kHz.

High-Pass Output— Dedicated 2-pole (12 dB/oct) high-pass-filter output.
Audio Input— Audio input to the filter.
Pitch CV Input— 1 V/oct CV input controlling cutoff frequency; enables accurate pitch tracking when the filter self-oscillates.
Resonance— Sets filter resonance; at maximum it causes self-oscillation.
Low-Pass Output— Dedicated 2-pole (12 dB/oct) low-pass-filter output.
FM Attenuverter— Attenuverts the FM CV input: clockwise increases cutoff with increasing CV, counterclockwise decreases it, and noon disables modulation.
BP/Notch Output— 2-pole (12 dB/oct) bandpass or notch-filter output, selected by the BP/NOTCH switch.
FM CV Input— CV input for cutoff-frequency modulation, scaled and polarity-controlled by the FM attenuverter.
Cutoff— Sets the filter cutoff frequency, combined with modulation from the Pitch CV and FM CV inputs.
BP/Notch Mode— Selects bandpass or notch operation for the BP/Notch output.
Clip Mode— Three-position input treatment switch: up soft-clips then boosts by 6 dB, middle passes the input unprocessed, and down soft-clips with no a
Clip Level— Indicates the post-Clip-switch signal level entering the filter; brighter illumination means a hotter signal.
