Description with steps to reproduce
- Shif+f9 to create a key signature and drag Koron for B on the middle line.
- Press N to write B and Play the note. it doesn't work correctly (it didn't decrease -50cents)
- Try to put Koron next to the note (not key signature) , you may see it decreases -50cents without adjusting in tuning.
- If this problem will be solved, it will be great
Supporting files, videos and screenshots
When I use quarter intervals (koron and sori) in measure, it works correctly in the last update of muse score.
It means I don't have to go to properties to adjust tuning ±50 cents 👐
That's a good news when I put Sori or Koron next to the notes , it effects .
but when I put Sori and Koron on the key signature it doesn't work like sharp or flat.
I hope it will be solved because I don't want to put Koron and Sori in each measure.
