haven a hard time samplein'

im haven a hard time samplein straight to the mpc.its like when sample sumthin, its doesnt loop perfect .it doesnt fit in a 2 bar sequence or when i do it with 4 bars its short,what should i do???

There are a couple of different things you can do, time stretch, tuning. The first thing is make sure the sample is chopped to loop properly in the first place. Once you're sure you have a decent loop go into the TRIM screen and hit EDIT> scroll to TIME STRETCH and hit BPM> select the right amount of beats for the loop and it should tell you what bpm your loop is at in the Source tempo field> go down to New tempo and change it to whatever tempo you want the sequence to be(drastic time stretching will result in the sample sounding like garbage)

BPM Is the tempo right?

yes sir it is

just remember when you tune, you may change the key of your composition, when you time stretch, it keeps the sound intact, in other words, it doesnt raise or lower any notes.
