Not all parts swing in playback

[BlackmonJoe]

Hey, I'm writing a saxophone quartet. I've got the style set as swing and the soprano is doing that. But when all 4 parts are playing 8ths some are not swinging. What could I be doing wrong?? Thank you in advance.

I suppose that you created the Swing playback with an expression from the Tempo Mark expression category, right?

Take a good look at the Tempo Mark expression category:
Document menu > Category Designer…

In the Category Designer, highlight the category Tempo Marks.
Then, next to the Score List, click the button ‘Edit…’ - to examine the category’s Score List.

In the column Part, make sure that all 4 staves have a check mark.

You are correct. That fixed it for me. THank you.
