I can hear this reverb algorithm to my mind’s ear. It’s definitely akin to Shimmer, but more like the pitch algo “Crystals” embedded in a reverb effect. Not quite as pronounced as the Crystals sound, though – more subtle and random in character. Again, something similiar to Shimmer but with the shimmer voices replaced by a subtle version of Crystals with random delays and random selection of octaves and maybe also fifths.
