Pittsburgh Modular Synthesizers Lifeforms Eurorack Voltage-Controlled State Variable Filter Module

A deeper exploration of the Pittsburgh filter sound, Pittsburgh Modular Synthesizers Lifeforms Binary Filter is a voltage-controlled analog state variable filter based on the filter of Pittsburgh's Lifeforms SV-1. The state variable topology was chosen because it allows for a very smooth and natural-sounding filter in addition to offering several other modes of operation, each with a unique sound and energy all its own.

There is no sweet spot
This filter embodies the 'Jekyll and Hyde' sound of Pittsburgh Modular. On 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 Lifeforms 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 Modular 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, Lifeforms Bipolar Filter will not self-oscillate and operates as a clean, organic filter. Set to Unstable and without an incoming audio signal, Lifeforms Bipolar 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 Lifeforms Bipolar Filter starts to struggle with self-oscillation, the Q adds anything from ringing fuzz to heavy distortion to the incoming audio.
