google can explain better than i can… but, granular synthesis isn’t delay…. it chops your sound into tiny fragments and then let’s you re-arrange the playback of those fragments with, generally, control of the shape and pitch of each grain. it’s rooted in sampling more than echo because you can re-arrange fragments in time, not just repeat one particular moment of time.

there have been piles of granular plug ins over the years (google comes in handy here) and with the H9000’s DSP power it seems like real time sampling and granularization may be attainable.
