ALM Busy Circuits Pip Filter Compact Low Pass Filter and VCA

The ALM ’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 into 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.
