Vintage-classic ADSR Envelope Generator

An authentic reproduction of the original ADSR unit from a legendary modular synthesizer system, the Behringer 911 Envelope Generator Eurorack module is a powerful sound-sculpting tool. Laid out in a standard ADSR configuration, the 911 Envelope Generator provides wide-ranging time intervals from 2ms up to 10 seconds, for tight snares and bursts, snappy pitched percussion sounds, epic stabs, and long, liquid drones. When building a Eurorack synthesizer, having an excellent envelope generator is essential. And, whether you’re using it with other Behringer System 55 modules or third-part modules, the 911 Envelope Generator is a stellar choice to add to your Eurorack arsenal.

The Behringer 911 Envelope Generator, part of their series of vintage Moog-inspired Eurorack modules, is a four-stage envelope generator, perfect for controlling VCAs and filters. The four-stage envelope features controls for attack, decay, and release time, plus sustain level, creating your standard ADSR envelope. The range of times per stage is wide and goes from 2ms all the way up to 10 seconds. This allows for everything from super snappy envelopes to longer envelopes that develop and shape parameters over time.
