I hope this is all in order, this is my first post to this forum. Let me know if I should do anything differently.

Here's a patch which chops a loop into slices and plays them in a random order. The slice sizes are musically useful divisions also chosen at random. The speed of playback can be scaled as well with the speed slider. Turning off "vary scaler" locks the division size, but not the note length. Turning off "vary note length" locks the current note length, resulting in playback at different speeds for each division. The "jump to slice function" jumps directly to the new sample slice start when active. When deactivated, the playback counter slides towards the sample end. This results in reverse playback and sample speed changes.

You can see it in action here:

The hardest part of the patch was getting the "jump to slice start" functionality to work. The "trigger bang bang" object ensures the jump to start happens before the sample starts playing.

Download the patch here:

Load a sample by clicking the bang towards the top of the patch, then click the "start playback" toggle box. The speed slider must be moved from 0 and the check boxes beside it should be activated.
