MPC2kxl - Triton Studio - Motif Rack Connection ?

can somebody please tell me how to midi all three up so they interact with each other? when i just had the triton & the mpc, i had them midi shake & everything worked perfectly. . .now i want to connect all three so that the triton controls the motif rack (meaning when i play the keys on the triton, i hear sounds from the patch thats currently selected on the motif rack). . .i currently have both the triton & motif rack midi shakin with the mpc and the midi thru of the motif rack goin to the mid thru of the triton & i dont hear anything. . .i looked on page 258 of the triton studio parameter guide & as usual they show every scenario but yours. . .

also once i do hook everything up can somebody tell me whether or not i will be able to change patches from the motif rack by using the triton or mpc?

any help is appreciated. . .

nevermind. . .the motif rack wasnt plugged in. . .
