odd key signature
OS: Windows 10 (10.0), Arch.: x86_64, MuseScore version (64-bit): 126.96.36.19992, revision: 58dd23d
In the attached screenshots:
The change of key in the full score is spot on. (oddity1)
But in the Alto1 part (oddity2) it is way off BUT the pitch of the notes is correct.
Note in the two screen shots that the "Concert Pitch" button is in the same position (an error I have made previously doh!)
mscz file also attached.
