Small tips is to think what are you chopping?
If you were a dj you would either be; scratching a riff
live looping a phrase
chopping up a hit or riff
live looping a beat
As a dj you would be thinking in musical time as a measure, whole note, half note, quarter note for phrases, and quarter notes, 1/8 on down for the drum hits.
As a dj you would want to align the beats of your records, phrases, hits on time so you would think of the kicks lining up and for some snares of everything you mix together so that is blends well.
As a dj you would listen to your records first to see how the rhythm was played and what instruments were used. Then when you go to mix two beats they would blend well.
Basically when you chop on a sampler you are essentially doing some of the techniques and mixing that pro djs use when doing a live remix. I hope is helps.
