Albedo is a granular cloud reverb plugin for KORG prologue, minilogue xd and NTS-1. It continuously records audio into a buffer, and at the same time plays multiple looping snippets from it – with each such snippet or “grain” having its own randomized size and position. Together with feedback and additional stereo widening, this creates a lush “cloud of sound” reverb effect. The algorithm also features a “freeze” mode: it can stop overwriting the buffer and play the granular cloud indefinitely, making it possible to layer any other sounds on top of it. This plugin comes in two versions: 16 grains with forward playback (+) and 10 grains with reverse playback (-).
