no problem cuzn. hope it helped.
you can use Midi Time Code or Midi Beat Clock with the MPC and Pro Tools.
some people say midi time code is tighter, but i use midi beat clock and it works fine. midi beat clock is easier to set-up in pro tools too. just go into midi studio set-up in pro tools, set up the mpc 2500 as a device, then all you have to do is enable midi beat clock in pro tools and set the mpc 2500 to slave as midi beat clock and you're good to go.
make sure you set your tempo in pro tools to match the mpc.
pretty easy to set up and get going, plus you can focus on making the beat in the mpc and then once in song mode just sit back and track it out into pro tools. then you can mix in pro tools, plus have all the pro tools editing feats to change the beat up or add sound into it, fly sounds in from the mpc, etc...
the hardest part about doing it this way is the time it takes to track out each sound full song length. 3 min beat, 10 sounds, 30mins of tracking out.
