Emu XL-7 & MP-7 User's Group

I got a Karma on Sunday. So now I am going to hook everything 
together and want a second opinion if this would be the right way to 
slave the XL-7 and still be able to trigger samples on my PC. I am 
using a midiman 2x2. 

So, I am going to go from the Karma's out to the midiman A in. 
The midiman's A out will return to the Karma. 
The midiman's B out port will go into the XL7's in port amd the XL7 
out will route back to the B in on the midiman.

This should still let me do edits via E-loader and use the Karma as a 
controller for the XL7 and software, right? Or should I be using the 
through port on the Karma?

I am not a networking type of person. So, I have looking at all of 
the different schematics from all the vendors and I think I need a 
drink. Any help would be appreciated. Thanks in advance.
