Reply to denon mc 3000

any 1 help please ? just a few things i havent managed to figure out on the denon mc 3000 , i dont remember reading how to do these things in the guide either ,, 1st how do you load tracks into the loop recorder at the top centre of traktor pro 2 ,, 2nd is there any way of changing the pitch of the samples loaded into the remix decks to match the playing track ,, i see a bpm at the end of the box and tiny up and down arrows buy nothing happens when i try to adjust with the arrows ,, and how do you delete the sample banks ,, thanks
