The ‘Pip Filter’ is a compact 4HP voltage-controlled 2-pole low-pass filter with resonance, a ‘pingable’ trigger input, and built-in VCA.

Filter cutoff is controlled via both knob control and dual CV inputs with a built-in attenuverter. Resonance is manually controlled and will reach self oscillation with rough V/Oct tracking. A trigger input allows the filter to be pinged for percussive plucked type sounds. Finally, a built-in VCA (normalled open) allows for additional independent amplitude control of the filtered signal.
