How do i get my midi keyboard to play the samples as notes?

Ive hooked my midi controller up to my mpc1000, all is good i can play sounds via the controller but this is a duplicate of what is loaded into the pads.
BUT !!
I was wonderin' is there a way to play my midi so that it plays a chosen sample from my mpc as a note?
i.e if a load a horn stab to a pad and then press a key on my midi controller to hear it can i play that sample across all keys on my midi controller as a real keyboard would?
Im sorry if it duznt sound too specific but would really appreciate it if any of u guys can help me out??
PEACE !!

You could try using a keygroup program instead of a drum program? Not too familiar with the 1000, so this can go ......
