Eurorack: Coma Reactor Delay

NEW COMA REACTOR RELEASING MARCH 2022

Taking equal inspiration from gritty delays on cheap on board mixers, the sounds of dub and the fracturing of consciousness in time and space, the Coma Reactor looks like a deceptively simple delay module... till you start digging deeper.

The Coma Reactor boasts the crunchy sounds of the PT2399 chip, but adds a number of useful routing possibilities that really open it up for sound mangling that transcends the norm. Independent volume controls for dry, wet and effects return, allow you to blend in clean, delayed and effected sounds to suit your needs. The only CV input on the module increases or decreases the delay time, going from slight tape-echo warbles to some truly seasick pitch shifting. A buffered clean through allows you to pass an unaffected unity gain to a mixer or other device.

If that wasn't enough - a truly nasty bandpass filter lurks in the delay feedback path as a dirty cocked-wah effect of sorts, and the module is also capable of generating noises and oscillating with no input attached, making it a useful soundtrack generator for the end of the world.
