SolarGravity / Analog Vactrol-Based VCA - Eurorack Module - 4hpThe Solar Gravity is an analog vactrol based VCA designed to bring the lovely response of optocouplers into the realm of clean, performance based Eurorack VCAs. Starting with this simple concept, the Solar Gravity utilizes some neat active circuitry to significantly reduce the bleed inherent in vactrol based VCAs and to provide the user with lots of control over the level, direction, and response of incoming control voltage. Though its primarily
