possible workaround:
- add multiple samples on the same track
- adjust start/end of the samples
- set high playback speed with some random playback order
- adjust reverb to your taste
- you can even make some variations to change the sound’s character on the fly later
- profit
cons:
- it uses the whole track
- everything is made by hand and cannot be automated
all in all, I wouldn’t expect much more than what we have now.
