I just noticed that the performance 'Edit Flag' (p.111 of Operations doc) will appear whenever you move the View Mode knob on the performance home screen.
It just reinforces the fact that the display of an 'Edit Flag' is virtually meaningless since it is almost impossible to load a performance and ANYTHING without some parameter, somewhere, being changed. The instrument doesn't really have an 'Edit Mode' so any controller movement (knob, slider, pedal) is almost always going to change an actual parameter value just in normal operation.
Then if you save the performance the next time you load it that 'changed' parameter value will be the new norm. That is just one of the things that can bite you at startup since that parameter (and others) won't have the starting values you so carefully programmed into the performance.
To be sure the normal playing of a performance is going to change a lot of parameter values. And that won't hurt anything unless you mindlessly/intentionally make a REAL change and then store that real change - the parms that changed in the background will get stored with whatever their current value is and they will no longer have their original design value.
1. load Init Normal (AWM2) - or any perf
2. notice there is no 'Edit Flag' displayed on the home screen
3. move the View Mode knob far enough to actually change the mode
4. notice the 'Edit Flag' is now displayed on the home screen
Tests show that the view mode is saved with the performance. So if you load a performance and change the view mode the Edit Flag appears and indicates that the performance has been 'edited'.
Although it doesn't do any real damage it does seem to mask whether the performance has actually been changed by the user.
