USING MPC X PADS TO PLAY MPC X DRUM SOUND IN PROTOOLS

I NEED HELP . I SIMLPY WANT TO PLAY AND HEAR MY MPC X DRUM SOUNDS INTO PROTOOLS AS MIDI USING THE MPC X DRUM PADS TO TRIGGER IT'S OWN MPC X DRUM SOUNDS INSTEAD OF USING A KEYBOARD MIDI CONTROLLER BECAUSE THE MPC X DRUM PADS ARE PERFECT FOR MAKING DRUM BEATS , BUT WHEN I ASSIGN THE DRUM KIT TO GO OUT OF THE MPC X PORT A INTO THE MIDI INSTRUMENT TRACK OF PROTOOLS AND MATCH UP THI MIDI CHANNELS I CAN VIEW THE MIDI ACTIVITY IN BOTH PROTOOLS AND ON THE MPC X SCREEN AND ALSO EVEN RECORD MIDI DATA INTO PROTOOLS BUT I CAN'T HEAR ANY SOUND COMING FROM THE MPC X WHEN I HIT THE PADS OR PLAY BACK THE MIDI RECORDED DATA I CREATED INTO PROTOOLS. CAN ANY ONE TELL ME HOW I CAN HEAR THE THE SOUNDS FROM THE MPC X WHEN I PLAY IT'S PADS AND RECORD VIA MIDI INTO PRO TOOLS ? SEEMS LIKE THERE SHOULD BE SIMPLE SOLUTION TO THIS PROBLEM BUT I HAVE ALREADY SPENT A MONTH TRYING TO FIGURE IT OUT WITH NO SUCCESS .
