Reply to help with IG + cue mapping

Need help with the mapping that i have my mind,

want to use 4 banks mode.
A and B on decks with IG.
C and D as cue points or sample deck.

questions like: with every differant cue point, does the m1 or m2 change or is it all m1?
and with is the command buttons for the 4 banks mode? thats the only i should save in the command list?
thanx!
