sync pro tools + 2500

i have hooked up my mpc as the master and protools plays when i press play on the mpc, but no sound comes out of the mpc and it does not play either
what does appear under everything on the main page of the mp is "waiting for midi play"
i have a feeling ther is a real easy solution to this that i am unable to see.... can any1 help me out

neva mind i figured the shit out

post up how you did it so this doesnt have to be a waisted post

instead of slaving protools to the mp, i made protools the master, the mpc now responds. so i didnt really figure out what the problem was, but for what i wana do with pro tools, which is basically just mixing down, i can settle for this. i have been told that, apparently, having the com as the master is betr off anyways. any thoughts??

^^are you recording your mpc tracks into protools? cause im attempting to do that and ive got PT as my master and when i hit records it enables the mpc so i can hear it coming out PT but i cant seem to get a signal into my PT traks to record. i have a feeling it has somethin to do with the way i have my tracks routed but i cant figure it out for shit.....any thoughts
