[1.2] Transposing Instruments Import/Export Problem
I have a problem with MusicXML import/export of transposing instruments.
If 'Display in Concert Pitch' is set on a score that is exported, then exporting via XML and reimporting into MuseScore results in the actual pitches of the instruments being shifted.
Attached is a trivial example of a test case, a unison on oboe and two clarinets. Export it to XML then import it and (whatever the 'Display...' setting) the sounding pitches have shifted from the intended unison.
