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

Hey guys, newbie question here. I have been creating my own patterns 
and saving them with the xl7. I have been having a problem though 
when I turn off the xl7. When I turn it back on, all of the patches 
that I have set up for the individual tracks for my pattersn are 
changed to some default set up. I have tried several times recording 
and saving the patches that I want to the patterns that I have 
created. What is the correct way to save these patches to patterns? I 
have tried to research this issue in the manual and there is no clear 
cut decription of how to deal with this issue. Thanks again for any 
help.
