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

Hi guys.
I have owned an XL-7 since the release date but this is my first 
post.

I have written many patterns since purchase and have been very happy 
with the machine but I seem to have switched a setting somewhere 
that is changing some of my tracks presets to the same presets from 
other patterns.

I did change the Master Effects from (use Master Settings) to (Use 
Preset on ch.11) and changed back when I noticed this 
squirelliness.  I even reformtted the XL-7 and installed 1.32 
(although only shows up as 1.31 in the XL-7).

Since the reformat (one day) everything was fine.  New and old 
patterns playing with their assigned presets but when I got home 
today and started playing it I have the same problem again.

Please help and thanks for reading.
