Description

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 a signal 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 well to +5V triggers to give 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 low pass gate.

 

The Kit includes all the parts to build the module. You will need a soldering iron and multimeter to build the module.
