    The state variable topology of the Binary Filter was chosen because it allowed Pittsburgh 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 unstable mode turns the Binary Filter into a howling beast capable of chunky walls of overdrive and noise. The goal was to produce a filter that does not have a single sweet spot. Pittsburgh 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.

    Switch It Up
    The stability switch selects between Stable and Unstable modes. Set to Stable, the Lifeforms Binary Filter will not self oscillate, and operates as a clean, organic filter. Set to Unstable and without an incoming audio signal, the Binary Filter produces a high quality voltage controlled sine wave. Adjusting the Q while in Unstable mode modifies the shape of the waveform. Add an incoming audio signal to the Unstable mode and the output changes dramatically. At normal settings the incoming signal modulates the self oscillating filter to produce complex sounds. At more extreme settings, where the Binary Filter starts to struggle with self oscillation, the Q adds anything from ringing fuzz to heavy distortion to the incoming audio.
