Added alternative mode how the per-fragment pitch envelopes work, which also now finally allows reverse playback of the material. (Without using the offline reverse preprocessing step.)
Think of it as something like scrubbing the audio material playing within the fragment. (Or grain, but I really prefer the word fragment myself.)
The sound is a bit too glitchy at some moments in the demonstration video, but I will work on making it work a bit better.
Another demo with another type of source sound
