Quick Question?

aight i got my mpc shit sorted now i got all my meg and zip so ima ready to go. i been playing abouts with it and read a little bit of the manual but i was wondering when u bussin out your drum patterns in different sections like u buss a lil out on track 1 track 2 etc.. when u buss it out can u buss it out and some bits might be a lil off how do u trim down or whatever, the bits u laced and if u got like the 2 drum hits u want can u copy n paste this so u dont have to bother drumming it out for like 10secs? any tips on creating drum patters would be helpfull aswell.

pz.....

On the main menu go to edit and you can copy and paste
from wherever to wherever.
This is in the manual..

Also, Shift+5 is trim.
Again this is in the manual..

I didn't quite understand the rest of your post
not specific enough homie..
