Hi all, Recently, my M9 has an strange behaviour regarding autosave. Let's say that I do some changes in the settings of an effect. That works fine. But later, if I switch off the M9, and then I power it up again, the changes in the settings that I made are lost... I've noticed that, if I change to another scene before switching off the M9, the changes in the effects are stored. In the scene prefs, I have selected "Autosave"... What can be wrong? Thank you in advance.
