Pittsburgh Modular Synthesizers Lopass Gate Module

Descripción

Lopass Gate Module. The Pittsburgh Modular Lopass Gate module is a new take on a classic. The intention was not to clone but to reengineer and expand on the original idea. The LPG module includes an amazing self-oscillating resonance circuit and a quieter vactrol based VCA circuit with true unity gain. Voltage control of the module is handled using an invertible, attenuated input and ping input. The ping input takes any gate or square wave and converts it into a very tight trigger used to ping the vactrol. In low-pass filter mode, frequency sweeps are warm and buttery and resonance is smooth and controlled until it gets near self oscillation. At this point the Pittsburgh Modular LPG module turns into a shouting beast. High resonance creates an edgier, shattered, more direct sound. It never loses control but is always teetering on the edge. Having both the smooth and snarling responses available creates a filter that is perfect for almost any situation.
