help with pitching up and sample in the mpc

hey everyone i got jjos2 and please let me know if im going this wrong so im recording in a sample / changing my bpm to the bpm i want/ then going into trim mode to get the loop of the 2/4/6/ bar loop that i want then i pitch it up until its close to the bpm click then i start chopping is that a good way or the right way of doing it i had the mpc for 4 weeks now and i still cant get my hanhof things.

That sounds right to me, chop sample into a loop - as in a regular number of beats or bars, then adjust pitch of that loop to get the same bpm as your sequence, then chop that. All will be at the same pitch/tempo as that from which you chopped.
You could also use time stretch to adjust a loop to your required bpm.

Or chop it down to individual hits in CHOP, then either convert to a patch phrase or make a kit from the individual chops and re-sequence
