At a particular point in a score layout, I want the barline in all staves to be a double barline.
I select the barline, open the barline tool and click on the double barline icon. Some instruments retain the double barline that I have already selected, but the single barline staves remain stubbornly single barline. Possibly of note is that when selecting the prevailing double barline, the single barline staves are not selected, they have to be manually joined to the selection.
Some particular conditions encircle that barline. I have no idea on what there significance might or might not be.
At the barline, there is a key change.
At the barline in the immediately preceding bar, there is a meter change in some of the staves. Mostly, it is in these staves the barline in question refuses to turn double.
That meter change is reversed at the problematic barline (that, mind you, has the key change also), and hidden in the staves concerned, so to appear that the meter continues to be the one from the preceding bar.
I realise this is a very complicated attempt at explanation. It’s the best I can manage!
Maybe the attached screenshot will reveal something interesting?
Thanks for reading.
