That is something I’d love to see as well, some people have requested it in the past. The thing is that we are a very limited public.
But mind you, I see more Eventide pedals in synth setups than guitars! So both worlds would be more than pleased to have something like that.
Looper algorithm can do some granular-like sounds if you mess with the start/end points, length and varispeed, but you have to rely a lot in the expression pedal or MIDI CCs, not to mention is way too awkward and is easier to end up with a total uncontrolled chaos, which is the desired result of course, but a dedicated interface, similar to MI Clouds would be more appropiate!
