I’ve been exploring the All-Pass Reverb techniques described by @polarity. I’ve opted to lean into a 5x5 setup. All values are pulled from a list of Primes from #Wikipedia. There are 5 parallel rows of 5 nodes in series and the results are rather satisfying.

My AS AP 5x5 Reverb is presently nested into the Fog stage of my latest #SealEggs #NauticalDelay preset.
