Beat/sample Chopping

Ok, You’ve got a beat loop fitting perfectly using beat sync. Now how do you go about chopping that loop up into segments and still keep the time of the loop. Is there a way of applying the beat sync to the actual sample? Then you could cut the sample up into segments.
As a Drum’n’Bass producer its a huge problem for me a break beat manipulation plays a big part in my tracks.

Can anyine shed some light on the situation?

Cheers peeps
