ADSR Envelope

The SetonixSynth DOUG is a simple-yet-powerful single ADSR module, made to deliver a wide variety of useful envelope styles in a small package. A true WYSIWYG design, the user can patch Gates, Triggers, or Square-Wave LFO’s into Doug’s Gate and Trigger inputs and quickly dial in the perfect envelope for percussion, rave stabs, ambient swells, you name it! Perfect for obsessive twiddlers.
