A granular reverb and delay, inspired by Haze from Microcosm (note, I don’t own one; have only listened to videos and it’s probably nothing like the real thing).

Footswitch A toggles between a +1 or -1 octave.
Footswitch B toggles between with or without an added octave (connected to A).
Footswitch D (A+B) toggles between larger or smaller grain size.

In addition to video below, the patch is used here: https://youtu.be/RUm14Zw-rF4
