Here's a sneak preview of Buffer Shuffler, a premium audio effect that comes with Cycling '74's Max for Live.
This audio effect "shuffles" incoming audio by buffering the audio, then replaying it in whatever order you've specified. Each channel of the stereo signal can be shuffled with different patterns (unlike Beat Repeat) and there is also a "dice" mode that randomizes the shuffle pattern at each bar crossing. Finally, a smoothing setting limits the amount of clicking at each transition point. Use sensibly to add subtle variations or go full-on to see where it takes you.
Max for Live is a tool kit that can be used to make new devices for Live.
