Notes are wrong after changing instruments

When I change instrument in a part, if the old/new instruments are transposing instruments, the notes would become wrong after changing...


What's worse, after I try fixing the notes in the part, the other parts sharing the same staff would become wrong too.

Do mean you have a score in which you've already generate the parts, and then, in either the score or the part, you change transposition, but don't change it in the other? This will indeed resulting in things being out of sync. You currently need to make changes like this before generating parts (so, delete the part and recreate it if you change your mind later). See #62416: Changes to staff transposition (and other properties) not reflected in linked parts.

yes, that's a direct result of the transposition info being out of sync, two different "views" onto the same note, and it just doesn't work because the note was already transposed for one view and the other just gives the wrong answer.

If after looking at the issue I linked you believe yours is different, please attach your score and steps to reproduce. Pretty sure it's the same, though.

I am not sure if this is what you meant by not reflecting changes.
See attached file and play with it.
See there is a main score tab and Alto Saxophone part tab? Note that the notes look the same on both tabs:
E Key: C# D# E F# G# A B C# G# A B C# D# E F# G# A C#

Now try going to the Alto Sax tab. Right click on the empty area of the stave and choose "Stave/Part Properties..."
Change to a different instrument. Let's say Woodwinds > Tenor Saxophone. Click OK.
The Alto Sax (Tenor Sax?) part tab looks OK. (except that the part name should be updated instead of staying as Alto Saxophone... but that's another issue.)
The notes are correctly transposed accordingly for the instrument:
A Key: F# G# A B C# D E F# C# D E F# G# A B C# D F#
Now, switch to the main part tab and take a look. boom! You will see the notes have gone horribly wrong. The note changes are not really just "not reflected", but they have gone really wrong on the main part tab.

Exactly as I said then - it's a known it won't work to have different transpositions for part vs score. It's important to get the instrument settled before generating the part. If you change your mind later that's OK, just delete the part and generate a new one.

Status needs info closed

BTW, the problem is that the change to transposition is not linked between score and parts. That is the reason the notes look so terrible. It's like you have a pair of secret decoder rings that allow you to view the note info, but you changed out one of those secret decoder rings. Trying to view the data with the other now-outdated secret decoder ring will yield nonsense. Same story with the transposition.
