[github-musescore-musescore-5786bb4] Key signature incorrect with double treble

• Apr 27, 2013 - 04:50
Graphical (UI)

On a double staff with a key signature, if bottom staff is changed to treble from bass, key signature doesn't change position to reflect. Key signature's incorrect position is reflected in new notes.

To reproduce:
1. New MuseScore file in 2.0 nightly, with single piano stave set.
2. Add key signature. (4 flats, in my case.)
3. Turn bottom staff into treble clef.
4. Go to new line.

File attached reflects bug on first empty line.

Palette > breaks and spacers > new line formatter. Looks like a blank sheet of paper with a carriage return symbol on it.
Or, it should work equally well to add notes until you get there. Or scroll to it.

I think I know what the problem is, though. Make sure you keep at least one measure of treble and bass before the double treble switch. Then look at a new line.

Oh, great, I finally got the second treble with the right key signature somehow, but now it won't let me place any notes on it. Apparently an instrument can't have more than one treble clef with notes on it. In note adding mode, it acts as if the second staff isn't even there.

??? Are you clicking on the staff you want to enter notes on? You have to do that before you can enter notes. It seems likely you might not understand how to do note entry in musescore? If so, you might want to ask for help in the support forums. If this really is something that you know how to do in 1.3 and works fine there but doesn't work in the nightly builds, please provide more detailed sep by step information on what you are trying to do.

As for the initial report, it looks like you have accidentally dragged the wrong clef to you score. See the clef in the bottom staff at the end of measure 8? Thtat's not a treble clef. It looks lime ne, but it's on the wrong position to be a regular trele clef staff. You must have grabbed one of the other clefs that looks lie the trble clef to your score. The rea trenle clef is top left corner of the palette. Aynow, that's why accidentals are not where you expect.

Oh. You're right about that being the wrong clef. Thank you for clearing that up. Doesn't explain the other thing, but I can reload from this save and be on my merry way.

I'll upload the other save with the second described bug if you want to take a look at it.

When you load this file in my program, and attempt to add a note to the bottom staff of the system in measure 9, it acts as if the second staff isn't even there.

Thank you for your help.

How are you doing it? I .loaded your score, clicked the bottom staff of measure 9, pressed 9 to go to note entry mode, and typed "B". And sure enough, a quarter note B appeared.

However, I'm guessing maybe you tried clicking on the lower staff while still in note entry mode for the top staff, rather than entering note entry mode for the bottom staff in the first place? That seems to not work on this score, while it does in other scores. So I'm guessing that this is indeed a bug. Steps to reproduce with your score:

1) Click any note in the *top* staff of measure 9
2) press N to enter note entry mode
3) click somewhere with the lower staff

Expected result, I think: a note appears in the bottom staff
Actual result: I hear the note played, but nothing appears

Actually, I think I have found the problem: for some reason, your score seems to have *two* treble and *two* bass clef staves, with one of each being marked invisible. You can see this by pressing "I" to display the instrument list. Guess where the notes you are trying to enter are going? :-) Anyhow, delete the spurious invisible staves and all is normal.
