Transposing From C flat to B natural

After transposing a piece, I noticed a number of parts moved to C flat in the final section. I was able to tranpose the section of a part down a diminshed 2nd to B, but the key signature for that section did not change. I then double clicked on the key signature in that part and entered in “B” hoping the key signature would move to B. However, nothing happens. The key says in C flat.

What am I doing wrong?

Did you activate the caret at the point you wished to change the key sig to B?
I’m not sure just choosing the existing key signature would be enough.

It should be sufficient to double-click the existing key signature and enter B into the popover, then hit Return, and it should work in either the part layout or the full score layout. Does it work if you switch to the full score layout?

I tried in both a single part (voice) and changing to “Concert Pitch” all of the parts and both double clicking on the key signature and highlighting the rest of the piece and pressing shift+K - entering a “B”. Nothing changes. The piece is still in C flat. I’m wondering if the XML part I imported which had an error importing may have had something to do with this problem.

I’m sending both the XML and the Dorico file I created. The only change I made to the piece was to transpose it from G up to Bb. From what I read, Dorico should have put the “C” instruments in “B” by default because it had less accidentals. (I did not turn on the override not to do this.) Please let me know what you discover.

The problem, David, is that (presumably due to the way the MusicXML file was encoded) you have a local C flat key signature on every instrument at bar 80. In the full score, select the C flat key signature on each staff, and you should find that this “reveals” the B major key signature underneath.

That is a problem!
When I change the Key to ‘B’, Dorico says, yep - it’s BMajor.

Then when I click on the key signature again, it goes back to C flat.

I’ll probably have to create a new score, copy the notes & chords over from the XML and then create new key signatures in the new score.
Unless you have a better idea.

To finish Daniel’s solution off: select the key signature at bar 80 on the top staff and hit Delete/Backspace. Select the key signature at bar 80 on the second staff and hit Delete/Backspace. Rinse and repeat for the rest of the key signatures at bar 80. Then input a new key signature.

You’ll probably then want to do some respelling of the following material. Selecting all of it and shunting up and down chromatically will fix much of it (Shift-Alt/Opt-Up then Shift-Alt/Opt-Down) or you could try the Respell Notes Automatically dialog.

There’s no need to copy and paste to a new file.

Deleting the key change and adding it back fixed my problem. I transposed the rest of the piece down a diminished 2nd to get the piece looking like it should. Thanks for your help!
