chopping samples/sampling question

hi how do you go about choppin samples so they can be played evenly on the pads one after another like pete rock does here: http://youtube.com/watch?v=jQWxrWSsI2k. I hope i'm explaining this okay but is this a matter of time stretching the sample so the bpms match up?
I'm real new at this and also when I record a sample it only lets me sample 11 or so seconds of the track. is that how its gonna be on the 2kxl always?

dont got xl, but you gotta chop it into zones. you should be able to specify how many zones you want. then adjust start and end points of each zone. so they dont pop or got chopped in wrong parts.

make sure whatever you sampled loops smoothly tho before you divide into zones
