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

Hi all, just bought my first XL7, and already love it as much as I 
hate it (which is quite a bit)...hopefully, it's mostly just matters 
of misunderstanding (hopefully)...one major question I have at the 
moment though, is, how do I manage to save the preset patches I have, 
in order to keep them assigned to there specific patterns....instead 
of having all the same 16 presets assigned to all of my patterns?
Thanks,
