PROBLEM WITH LOOPING & SEQUENCING

Hi i own the MPC200XL and have been having difficulty at times with looping and sequencing.

Say you sample a break, you trim and loop it. when you play it back it sounds perfect BUT when you go to the main screen and put it into sequence the loop apears to be to short or long and it doesnt loop seamlessly

What am i doing wrong ? do i need to adjust the parameters

time sig is set at 4/4
bars 2

you might need to bpm match it...
.
.
you know where you go to time stretch... select bpm.... where it says new bpm... put in the value you want...

Bro i appreciate your help im new here so ill be asking tech tips from time to time

oh yeah... go into loop mode first... highlight the loop.... and make sure the loop is on before you go into that section i explained above... if you do it this way... you'll see the bpm...

Thanks bro things are running well
