BASTL INSTRUMENTS / DARK MATTER

This module is made by Bastl Instruments, a brand of ""handmade electronic instruments."" It freely manipulates feedback to create unprecedented feel and sound.

A processor/signal generator that manipulates feedback to create unprecedented operability and sound.

Developed jointly by BASTL INSTRUMENTS and CASPER ELECTRONICS, ""Dark Matter"" is a high-energy sound processor and signal generator. It unleashes the ferocious power of audio feedback into your Eurorack system.

Inspired by the ""no-input"" mixer feedback technique, Dark Matter allows you to naturally guide your sound beyond the limits of amplifier circuits to complex tones. It's a new type of Eurorack modular synth that utilizes voltage-controlled feedback, making it extremely easy to play and offering a wide range of patching options.

Developed in collaboration with the BASTL development team by Peter Edwards, who moved from New York, USA to Bruno, Czech Republic, and has created numerous masterpieces within the BASTL commune, this product boasts unprecedented features.
