Importing MusicXML does not assign instrument ranges from instruments.xml
GIT commit: 3c7a69d
New to MuseScore, I tried exporting a score to MusicXML, then back to MuseScore format. Worked fine, except that afterward, the instrument ranges had been altered - every instrument had the max range - C-1 to G9. So the color marking of individual notes outside normal range wasn't working.
So either the MusicXML format doesn't support individual instrument ranges or the programmer never got around to implementing that. Here's a MusicXML file to demonstrate what I mean. It was exported from a MuseScore file which had proper alto sax ranges but now the alto notes don't turn red no matter how high or low. My_First_Score.xml
