Pittsburgh Modular Lopass Gate (LPG) - Filter, VCA, Low-Pass Gate - Eurorack Module

The Lopass Gate (LPG) from Pittsburgh Modular is a triple-mode module that combines three functions into a single module, including a VCA, low-pass filter, and low-pass gate. The voltage-controlled amplifier (VCA) controls the volume of a sound, while the low-pass filter utilizes a Sallen-Key design, which is a classic 2-pole, 12 dB per octave filter that is used in the Korg MS-20 and MS-10 synthesizers to produce a warm and buttery sound. Resonance has been added to further push the filter into sonic mayhem and snarls when approaching self oscillation.
