Thank you so much for this - it's such a wonderful little creative tool. In future versions, if there was some way to play back or preview each of the 5 subsamples, each on its own, in isolation, that would be great - just so you can adjust the length and effects on each subsample to taste (it's quite hard sometimes to do this when the whole sample is playing away).
But that might actually be going against the whole spirit of randomness and experimentation and probability that makes Granular such a lovely surprising thing. So feel free to totally ignore!
