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

I have the mp-7, I have had it a couple of weeks. I am having 
problems with presets being the same on each track, on all of my 
saved patterns. If I go thru each pattern & tracks even for factory 
saved patterns, all the presets are the same for each track on every 
pattern. So if I have patterns A,B,C with tracks 1,2,3...pattern A 
track 1 will have the same preset as pattern B track 1, and so on.
Even if I go thru and change the preset on a certain track on a 
pattern, and save...when I turn it off and turn it back on I have the 
same problem...what am I doing wrong??
