Each of the five modes pairs two algorithms with separate feedback paths, set by the Feedback and Regen knobs. Repeats pass back through both effects, so the texture keeps changing rather than looping. Modes run from reverse delay into reverse reverb, through octave-up and octave-down reverbs, to a dual-reverb mode and two opposing pitch delays.

The X knob changes role per mode, covering how reversed the delay trails are, reverb decay, or the interval order of the pitch delays. A Tweak button gives one knob five jobs: stereo width, modulation rate and shape, and the target and glide time of Dive / Rise. Holding the tap switch triggers Dive / Rise, which slows or speeds the pedal's clock while held.

Three presets sit on the pedal alongside a live mode, with 127 more over MIDI. Every knob responds to MIDI CC, and any knob can be mapped to the expression input. Trails or No Trails bypass is selected at power-up. A black finish is offered alongside the green one.
