Pittsburgh Modular Filter Used/Demo - These 2 units were part of demo systems. Work perfectly and no screw rash. Both include all original packaging. Save on practically new modules! Classic Multi-Mode Filter 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. 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 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. Filter Responses Multiple filter responses are available simultaneously including lowpass, highpass, and bandpass. The fourth filter response is a variable response that shifts between lowpass, notch, and highpass.
