## What is SL Passage?

SL Passage is an algorithmic reverb with five room characters: Corridor, Stairwell, Recital Hall, Glasshouse and Brick Cellar. Start with one of 20 factory presets, then shape decay, wet/dry mix, predelay and diffusion. Compatible hosts can automate tone, width, motion and return level.

The optional AI stage adds local neural colour to the signal exciting the reverb. Preset level matching helps reduce loudness changes while browsing. Neural processing runs on your device; it does not generate or download acoustic rooms.

Try a short stairwell on dry drums, a dark cellar on sustained synths or a long hall behind sparse notes. The filmstrip selects room character, and the liquid-glass display reacts to the processed signal. Save your own presets or use the die to choose a factory setting.

Includes an AUv3 effect and a standalone audition container. Insert the AUv3 effect in a compatible audio host to process your own track. The standalone container auditions an included original phrase and does not monitor external microphone input. No account is required in this iPhone and iPad edition.
