Expressive sounds always loaded when score is opened
Save a score with non expressive sounds set in the mixer
Close and reopen the score
Results: The score has all expressive sounds selected if the default sound font is MuseScore General HQ or this first sound (normally grand piano) of any sound font that does not support expressive sounds.
Expected: The sounds set when the score was last saved are retained.
Note that opening the synthesizer and clicking the button
Set all sounds: "To Non-Expressive"
has no effect.
The user must manually change each sound if they do not use expressive sounds. Not big deal in a Sax solo but a very long process in a Wagnerian Opera.
