Classic multi-mode filter module for Eurorack systems.

The Filter is a voltage controlled, analog, state variable filter. The state variable topology was chosen because it produces a very smooth and natural sounding filter, in addition to offering several other modes of operation, each with a unique sound and energy all their own.

There Is No Sweet Spot
The Filter defines the Jekyll and Hyde sound of Pittsburgh Modular. On the one hand, it offers a warm, organic sweep through the full frequency range. The low-pass filter is gummy and relaxed while the high-pass is clean and defined.  On the other hand, switching into oscillator mode turns the Filter into a howling beast capable of chunky walls of distortion and noise. The goal was to produce a filter that does not have a single sweet spot. Every turn of a knob or flip of a switch offers something new and musically engaging.
Filter Responses
Multiple filter responses are available simultaneously including low-pass, high-pass, and bandpass. The fourth filter response is a variable response that shifts between low-pass, notch, and high-pass.
Switch It Up
Two switches, Gain and Mode, further expand the capabilities of the Filter. The Gain switch modifies the functionality of the Q while the Mode switch toggles between filter and oscillator modes.

  • Q Pot: Adjusts the resonance (Q) of the filter
  • FREQ Pot: Adjusts the Frequency of the filter
  • L-H Pot: Sweeps between lowpass, notch, and high-pass filters
  • QCV Pot and Jack: Resonance (Q) control voltage input and attenuator
  • FCV Pot and Jack: Frequency control voltage input and attenuator
  • 1-Q Switch: Switch between Gain to 1 (VCA Mode) and Gain of Q (Standard Mode)
  • F-O Switch: Switch between Filter and Oscillator Modes
  • LOW Jack: Lowpass Output
  • L-H Jack: Output based off of the L-H Pot
  • HI Jack: Highpass Output
