Severed Space starts with a large feedback-delay reverb, then gives the dry signal two different ways to control it: a continuous envelope follower ducks the wet signal around the source as it plays, while a separate onset detector opens a hard time gate the instant a new transient arrives, cutting the tail off on command rather than letting it decay naturally.

TAIL controls what is ringing inside the space; DECAY TIME controls how long the door stays open before the gate shuts it. Push it toward the classic explosive gated-room sound, or use gentler ducking and a longer gate window for a large space that stays clear around drums and other transients — then shape what's left with CHARACTER, OVERTONES and ANALOG.
