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.
Features
- Compact filter and VCA in 4HP.
- Dual pole 12dB/Oct Low pass filter with resonance.
- Two frequency CV inputs, one with attenuversion and other with rough V/Oct tracking.
- Manual resonance control going into self oscillation.
- Trigger input for ’pinging’ filter.
- Normalled VCA input for optional amplitude control.
- Skiff friendly with reverse power protection.
