When I make change in PA9 using the mixer and restart song all changes disappear even with a save how to stop this from happening so I can tweak my song?
Sounds like you may have inadvertently taken a snapshot of the settings. I think you can fix this by taking another snapshot after you have the settings the way you like, but . . .
I agree with Moskus. Console View sucks. Use the Audio View and volume envelopes instead of the mixer in Console View. It's easier and with many less problems.
