Change key when changing instrument?

• Nov 6, 2017 - 00:41

I have written a part for Alto sax ( Eb ). Part way through the piece the Alto changes to Flute. I can alter the instrument by right clicking and playback the sound is changed to Flute, however when I print the music the key is not changed when the instrument changes. If I change the key in the score every part changes key. How do I fix this?



Do I understand correctly that the transposition works and the correct notes are printed for the flute, but you don't get a new key-signature when the flute section begins, and instead a lot of extra accidentals (sharps ♯ and flats ♭) in the flute section?

What you need to do is to add a new key signature yourself at that point, but only for the Alto/flute part. You can do this by pressing the ctrl key while you drag the key signature to the staff. See…

To make sure I add the correct key-signature, I usually go to concert key mode and add the exact same key as is already playing. When swithching off concert-key, the key-signature will be conrrectly transposed for the new instrument (flute in your case).

Just wanted to confirm the above is correct. Ideally the key signature would update automatically when you use a mid-score instrument change, but unfortunately I was unable to get that to work properly due to other problems in the underlying code I was relying upon. But I have verified it works to add a key change manually as described here.
