changing banks in logic without a mouse

Hey guys just wanted to know if it was possible like msb and lsb settings for hardware keyboards, is it possible to change logic instruments on the main page of the mpc 4000. Please note i am already using logic as a sounds module it works fine but i just wanted to know if i could cycle through sounds in the same manner as i do the motif xs from the mpc. So for instance i have a strings on channel 1a just wanted to know if i could change those strings to somethings else on channel 1a. Also is there a way to do this to battery 3 also from the mpc thanks for the help forgot to mention but this works with my vanguard within logic but so far no logic instruments.

Ok i guess either nobody understood me, or it was just too simple to answer. Anyway I found a video on programing my axiom to do this so im going try and grass the concept and apply it if its possible to the mpc changing the instruments if possible thanks anyways.
