Passive Vactrol LPG / LPF Low Pass Filter, Modular Synth Eurorack

This compact module combines a Low Pass Filter (LPF) and Low Pass Gate (LPG) in a simple passive design using a vactrol response for smooth, organic filtering and natural decay characteristics. Ideal for adding warm, percussive tones and classic “woody” LPG behaviour to modular patches.

Selectable operating modes allow use as:
* Low Pass Filter (LPF)
* Low Pass Gate (LPG)
* Bypass

The vactrol-based circuit gives a soft, musical response that works especially well with plucks, percussion, drones, and experimental patches.

Specifications:
* Passive (vactrol-based) design
* CV / Gate input
* Audio input
* Audio output
* Cutoff control
* Mode switch: LPF / LPG / Bypass
* 3.5mm jacks (Eurorack compatible)
* 6HP Eurorack Plate (available separately)

Measurements:
* 46mm x 74mm x 23mm
* 4 x 2mm mount holes

About Vactrols
A vactrol is an optoelectronic component combining an LED and a light-dependent resistor (LDR) in a sealed housing. As the LED brightness changes, the resistance changes smoothly, creating the characteristic warm, natural, and slightly slow response highly valued in many classic LPG designs.
