key signature auto insert with instrument changed

• Jun 15, 2023 - 21:55

In a Big Band arrangement I am changing the Bari Sax to clarinet and the already established key signature appears automatically. Oddly, it didn't do this when I changed the Tenor 1 to a flute (measure 9). Any clues on why and how to prevent it? k Thank you!

Pic 1 = before, Pic 2 = after. score attached.

Yes, changing from any instrument to the flute does not change the key signature. This is a bug!
Workaround: You can drag the correct key signature to the position of the instrument change while holding down the Ctrl key.

And additional: if you have a score using instrument changes and you want to change the key signature of the score itself also the changed instruments becomes wrong key signatures. A big bug!

I think you may have come across this bug https://github.com/musescore/MuseScore/issues/12800. I find the comments on that issue a bit confusing but it appears that a fix has been found and will be in the upcoming release of 4.1

Perhaps you could test the latest "nightly" version available from here https://musescore.org/en/nightly-builds to confirm this fixes what you are seeing. Note that the nightly versions are made available for test purposes only. Don't trust them with any valuable score - only a test copy.

As a solution for scores with instrument changes and/or a subsequent key change of the score having wrong keys I found out:

  • Switch to concert pitch mode
  • Drag the key of the score while holding down the Ctrl key to all measures with an instrument change.
  • If desired, switch the concert pitch mode off again.
