The idea is to diffuse *without* comb filtering.
Don't know why you're saying "not at all",
I'm just repeating reverb 101 there.

:-) I think I can guess that analog is a different implementation

Two sets of allpass? They're all linear processes so order is not
important. Or is there some other element involved?
Actually, listening to the demos more it doesn't sound so good on
complex chords, and it's rather more metallic on some notes than others.
Wouldn't be at all surprised if there's some techniques taken from
the EH pedals that *do* use granular techniques, used in order to
get the sound seamless. Doesn't the Hog have a freeze mode which
Anyway, I prefer the sound from the Vortex ;-)
