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

Hi,
other problems I have are:
1. the tempo does not save correctly. When I change my pattern   
manually the tempo setting does not change.
2. sometimes I power up my xl-7 and many quick edits are gone (-> yes 
I saved them in the present).
3. sometimes I power up my xl-7 and the presets of my pattern have 
changed although I have saved my pattern correctly. When I save my 
pattern two times in two different locations one of them have still 
the right presets. That´s crazy...
All that I`ve described happens sometimes although I always save my 
work correctly.
Does anybody out there have the same problems with his xl-7? This 
problems are very annoying...
