Mac Midi Setup & MPC2500

Any mac users who can help?

I can't figure out how to setup my MPC 2500 in OSX's Midi Setup. I created a MPC 2500, but how many ports am I supposed to assign?

This is what I did: midisetup - flickr.com

well it looks fine to me but i'm running an m box 2 so i only assigned 1 in and out from my mpc2500, mainly because thats all i can and need to use, out of the mac to sync, and into the mac to trigger midi. if your doing the same then you will only need 1 in and out from the mpc.
Peace!
