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

Hi all. I want to set up my XL-7 so that track 1-5 go to the main 
outs 6-10 go to out 2 and 11-16 to 3.  but I want to have it apply to 
all patterns.  I'm using my XL-7 live and I have to connected to 3 
channels on my mixer I want to be able to have one or two mixer 
channels running while I'm creating music on the third.  I can do 
this for a specific patteren but is there a way to make it apply to 
all patterens?  SO that I can start from scratch live?  thanks.
