I am a sucker for subtractive (being old) ok with additive and FM but grain not much... A bit with mimic but not impressed.
Then I saw this video:
Not a fan of grain patches, I never played too much with the synth itself. Oh boy how wrong I was!
Feeding a loop inside the spectral grain is maybe the funniest thing I have done since playing with a 12db LP filter, 25 years ago. Oh my, this formant! The fft ! The expressivity is just beyond awesome.
I am certainly the last person in this forum who hasn't spent ours playing with this grain marvel but if I am not, I could not encourage you enough to do so!
