Amazing plugin!!! My go too for granular stuff. One feature I would like is to have feedback on the pitch so grains can endlessly be repitched creating a complex sound. Think "Crystallizer" by Soundtoys. Gating would be nice too as well as some ADSR features on the grains so you can shape them grains
Pitched grain feedback would be interesting! I don't have any short-term plans to do this, but it might happen in the future
ADSR is probably the most often requested feature so I think it would be a very welcome addition.
I already did some work on the granular processing that allows ADSR envelopes (and pitch modulation) on grains. Needs some more work (optimization, UI, etc.) before I can release it but this is very likely to be added in a future update!
