The Filter is a voltage controlled, analog, state variable filter. The state variable topology was chosen because it allowed us to produce 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.
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 lowpass filter is gummy and relaxed while the highpass is clean and defined. On the other hand, switching into oscillator mode turns theFilter 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. We worked to make every turn of a knob or flip of a switch offer something new and musically engaging.
Power Usage: TBD
Q Pot: Adjusts the resonance (Q) of the filter.
