I was wondering if it is possible to hide the bar rests in an empty bar to leave a truly blank bar?
I did find one possible workaround: select the rest (or rests in question), open up the properties tab, turn the color switch on, and then choose a color and set it to 0% opacity.
It would be easier if there was built-in functionality, however. Can this be done?
You would have to use the ‘Ends voice’ property on the note previous to the bar rest in the same voice; switch on View > Note Colors > Voice Colors to identify which one that is.
