Accidentals show in F major

Dorico
1

Sorry for the unusual thread title.
I finished copying a piece for male choir.
The key signature is F major.
An intonation had to be added before the piece.
I started by adding a new flow at the end, just for this intonation, assigning it to Tenor 1 (only). As key signature I also choose F major. I started inputting the notes, a simple scale, f, g, a.
All these three notes showed a natural accidental, and I had to explicitly hide them.
What could be the reason for this unusual behaviour?
Also I temporarily changed the clef from g8 to C4 and transposed the whole thing by an octave.
When I reversed the step, the natural accidentals appeared and I had to hide them again.

It becomes even weirder. For layout reasons I decided against the extra flow and added an extra bar in front of the whole choir piece, just for this intonation. Then decided to have the intonation without the F major key signature. So via the popover Shift-K-C-Enter I changed the key signature to C major.
Weird: the actual key signature (one flat) stayed as it was, even if “C Major” was clearly showing in the signpost. My solution was to select the “b” and to delete it.
Everything felt fishy. I can’t explain why this happened. The choir is for three tenors and two basses, b.t.w.

@k_b, do you have a copy of the poisoned apple to upload?

You have looked at your settings for Notation options > Accidentals?

Yes, please have a look at the last “extra Flow”
and at the first bar of the first flow:
Lamentationes Jeremiae Prophetae, Liber Secundus -FORUM.dorico (3.6 MB)

Yes, the Options look inconspicuous..

I don’t understand how this happened, but if you transpose all the notes, the accidentals disappear. (I did shift-I t4 followed by shift-I t-4, but any transposition works!))

According to the Library Manager, it looks like the issue lies in the Accidental Systems section.

Thank you @charles_piano
for me a premiere to have a look at the Library Manager :slight_smile:
Still I don’t see, where exactly the difference to Dorico’s default settings are.
“Western accidentals to 12ET“ they seem to look the same in both columns.
Before synchronising/fixing, I would like to understand, where there is a difference.

I also had a look at Notation Options>Cautionary Accidentals - but those are not valid for a start of a new flow.

Your file has an entry for 0 cents flat. (Perhaps you have been experimenting with tonality systems?)

Thank you for pointing it out:

I have no idea, how this might have crept into the project.
I have never played with or edited tonality systems in Dorico.
This file started as a scan->music.xml file produced by PlayScore2.
It was first imported into Dorico for iPad and then later edited in Dorico Pro 6 on my desktop computer.
@charles_piano and @Janus, thank you for shedding some light onto this.

My guess would be there is a strange artifact created by Playscore2…

I opened the .xml file and could not find any hints for “Accidental System” or “cents”.
I also exported the Dorico project to .xml and inspected that file - nothing to find there either. Reimporting back into Dorico gets rid of that setting, too…
