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

I want to set up my MP7 with Cakewalk to sequence on the PC. I have 
an addded P2500 board so I cant use the avaliable instrument maps  
which would be the easiest way.
I need to be able to change patches/instruments/presets on individual 
channels mid project - not switching back and forth between E Loader 
and Cakewalk and transfering patterns back and forth and all that as 
its tedious..
I also need to be able to edit presets in realtime and for Cakewalk 
to record controller cvhanges realtime.
So basically I think i need the Cakewalk to master/control the 
pattern/sequence MIDI data, but for the MP7 to have real time control 
of patches/presets and transmit that data realtime
How do I set thisd up? Can anyone help?
Cheers
