I've spent some time researching setting up the MPC with Logic back, and thought maybe it'd make sense to post that in here.
I use my MPC with Logic. The majority of the time I use logic just as a sound module and do all my sequencing in the MPC. I've gotten a few PMs about how to set this up, and it did take me a while to get things sorted out for my own set up, so maybe posting what I did here would help others.
Audio Midi Setup
go into AMS and add a devices
double click on the new device and select the manufacturer, model etc. this will auto fill everything else on its own.
You'll see arrows on each device. these are just your In/Out ports of each device. This is where you'll copy virtually how your gear is physically connected with MIDI cables. so drag from the Mbox out to the MPC, MPC out to Mbox etc.
the next step is kind of the tedious part, especially if you've never messed with Logic's environment.
I probably couldnt explain it any better than they did on this page.

Make sure you save this as a template. File > save as template. so you wont have to do this everytime.
when you have all that connected. go to your MPC
Since there are 16 MIDI channels just change between the 16 devices in the MPC. each corresponds to one of the 16 instrument tracks you created in Logic. load up an instrument on a track. switch to the corresponding MIDI track on the MPC. and that should be it.
you'll have to make your own program in the MPC in order to trigger logic chromatically. What I mean by this is.. you'll notice that if you load up a piano or something in logic, and try to play it chromatically on the pads the notes arent in order and will jump around. So you'll have to create a program in the MPC corresponding the the right MIDI notes, starting at 36, 37 etc across the pads.
