MIDI Help Needed!!!

Okay here's what I have, I just want to know how it should be set up midi-wise.

MPC 2000xl
EMU PK6
MAC w/M-box
M-Audio 1 in 1 out usb midi interface

I want the MPC as master and I want to be able to play software instruments with the PK6.

do a search, this question is asked daily.

I tell you, it would help if you had a midi interface with more ins and outs.
Since the MBox takes up a USB slot, you'll need either an additional USB card or a powered USB hub that actually works with such demanding equipment.

But if you search under "Pro Tools and MPC200OXL" both here and at the Digidesign User's Conference, you'll get lots of info.

Peace.
