Bastl Instruments Dark Matter Eurorack Voltage Controlled Audio Feedback Module

Bastl Instruments Dark Matter Eurorack Voltage Controlled Audio Feedback Module

Bastl Instruments Dark Matter - Voltage Controlled Audio Feedback Module

Dark Matter is a high energy sound processor and signal generator that unleashed the crazy raw power of audio feedback into your eurorack system.

A little Crazy. Untamed. Evocative and Deep and kind of Awful and Totally Beautiful

It's inspired by 'no input' mixer feedback techniques that explore the complex natural behaviours of amplifier circuits pushed beyond their limits. Dark Matter brings this behaviour to the modular synth, adds voltage control to everything, plus tons of patching options and a big ol' bag of tricks for making feedback a truly playable effect.
