Solar Gravity

Vactrol Response VCA

The Solar Gravity from SetonixSynth and Tidbit Audio 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 it’s primarily designed for use with audio signals, the Solar Gravity can also be used to control the level of CV such as envelopes or stepped voltages with a unique vactrol response through its DC-coupled input.
