A Scene button selects one of three voicings. Intergalactic combines POG octaves, reverb, modulated delay and compression with the strings engine. Off-World is smoother, with more delay modulation and vintage synth textures. Etherdust is a glitch shimmer that breaks the delay into stuttering echoes.
The Voice knob moves from plate reverb at minimum, through shimmer at noon, to strings at maximum. Blend sets the effect level, Time sets the decay up to infinite, and Tone shapes the top end. Holding the Scene button opens secondary controls for reverb mix, delay time up to 950 ms, and modulation depth and rate. These are stored for each scene.
Holding the footswitch gives momentary infinite reverb. There are three bypass modes: Digital, Analog (buffered) and Hybrid, the default. Infinite hold works in Digital and Hybrid modes, and the pedal must be powered to pass signal.
