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

first let me state i'm still in love with the mp7, it's just some 
little things i can't get my head around that bug me sometimes... 
apart from the "not remembering the right preset" problem that occurs 
very seldom (maybe i'm the only one having this?) i also have my 
doubts about  "remembering the mutes in a pattern".... as far as i 
understand, everytime you get back to a pattern it should have the 
tracks muted that were muted when the pattern was saved, but 
unexpectedly, sometimes it seems to remember the mutes as last played 
(not saved!).
for example, i was gigging with the mp7 last night (for the first 
time, went surprisingly well considering the other half of the band 
was sick at home and we hadn't rehearsed properly anyway ;-)) and for 
the soundcheck i unmuted all tracks on some patterns. during the live 
show most patterns had muted tracks as saved but one pattern came on 
with all tracks blasting away!... no big problem, twas a bit of a 
mess sometimes anyway, but still... it just doesn't seem rational...
i don't know these things will classify as bugs, or maybe i'm missing 
something... any comments from other users would be nice!
