The Beepboop Passive LPG is a simple analog LOW-PASS GATE circuit based around a VTL5C vactrol with a fader to adjust the CV applied to the Vactrol.
Feed an audio source or CV into the IN jack and then control the amplitude of this signal applied to the OUT jack with the CV jack.
The module will respond to triggers, giving that classic LPG ping and ring sound or can be used like a VCA with envelope control signals.
The I/O switch changes the depth of the Lopass gate.
Lovingly designed and hand soldered here at Beepboop Electronics Workshop in Bristol.
