Someone said it depends on the OS release, earlier ones have a "low 
voltage" level a bit too high. This should have been corrected in the 
last one. When the backup voltage is really too low you can face random 
(and unwanted) patch changes at each turn on of the synth.

If everything gets lost, don't panic and perform a "full factory reset" 
as explained in the manual. OK, your own patches are gone with the wind, 
but you can play again...and program new ones.
Cheers.
