Lüm is a granular texture and reverb pedal that transforms your signal into immersive, evolving soundscapes. Drawing inspiration from the Slö Reverb, Lore Reverse Reverb, and Fable Granular Soundscape Generator, Lüm fractures your playing into tiny audio grains wrapped in lush reverbs, creating atmospheric textures that blur the line between instrument and ambient sound design.

Three distinct modes offer a wide range of sonic possibilities. Grain Cloud creates glitching granular textures from a feedback delay line, while Grain Verb embeds those grains into dense, washed-out reverb for expansive ambient sounds. Forward/Reverse Verb combines forward and reverse reverb algorithms for rhythmic, evolving reflections. The Stretch engine globally shifts sample playback from 0.5x to 2x speed, dramatically changing how grain size, reverb decay, and filtering interact.

Lüm also features Moment Control, allowing any of the five main controls to be automated by holding the Moment footswitch for expressive real-time parameter changes. Adjustable ramp times, seamless preset transitions between three onboard presets, and selectable Trails or Instant Cut bypass modes make it equally capable in the studio or on stage.
