You didn't mention audio monitors, do you have some? Part of answering your question would involve what are you using to hear the signal that will come out of your M-Box.
Yes it's totally possible to connect that stuff together and you have the essential stuff already to piece to together a very nice basic home studio setup.
The additional stuff you will need are 2 5-pin standard MIDI DIN cables. These will allow you to send and receive MIDI to and from the MPC to the computer through the M-Audio USB to MIDI interface. The OUT from MPC will go to the IN on the M-Audio and the IN from the MPC goes to the OUT from the M-Audio.
With the MIDI cables/interface plugged in you'll be able to to have the MPC control instruments in the computer or have PT or other software send MIDI. This has to setup in both the MPC and PT's preferences to ensure that they are properly synced to exchange MIDI data.
http://www.akaipro.com/syncprotoolsMIDI only sends note triggers and controller data, no audio. For your audio pick up 4 1/4" audio cables preferably balanced TRS cables. (made to reject most noise and EMF interference). Then the main outs of the MPC will go to the 1/4" inputs on the M-Box.
From there it's usually use the 1/4" outputs on the audio interface, M-Box here, to a set of self powered monitors. Home stereos could be used but are less accurate to monitor what you are recording. They will also have unbalanced RCA inputs (usually on a receiver for rack hi fi stuff or somewhere on the back of an all in one unit), so you'll need a set of 1/4" to RCA cables for that scenario.
If you need to sample into the MPC's inputs from the M-Box you have the limitation of it only having two outputs. Those are are going to be used by your monitors, so you'd have to unplug them and use the two outs to go the MPC. You could monitor using the headphone jacks though.
It's scenarios like this where some introduce a mixer into the flow, having other equipment like synthesizers also leads to some adding a mixer. Some use audio interfaces with more than two outputs so that monitors and audio outputs for sampling usage can be plugged in simultaneously.
Here's a great overview of all this stuff you're asking about. -
