1.Sample a break.
2.Loop, truncate and normalize. When doing these processes you'll find that the X makes a new file, most times you don't want that old file. To delete, hit the pad, hold down the (Sound) button in the Pad Section and hit (No/Exit). Answer the question.
3.Once looped and truncated it's 00 00 99 right? So just divide 100 by whatever you want to split it to. If it's 4 bars and you want a bar on every pad, do a Copy params only (Pad/Process) to four pads and set the Sample start/ends to 00 00 25, 26 00 50............. tweak to perfection.
4.If you want to pull kicks and snares out. Do the same thing "Copy params only" to a bunch of pads, set playback to ONCE FORWARD instead of LOOP, find starts and ends to isolate the single instruments.
5.Go to ENV3 and set all the pads to FINISH. This will make pad play through without having to hold it down.
6.Make even more copies and edit them, some simple ones to try are:

a) Panned versions
b) filtered versions
c) Effected and dry versions
d) reversed versions
e) detuned versions
