You can manually change staff visibility from the rhythmic positions of system/frame breaks onwards by hiding, showing, and resetting individual staves. For example, if you have hidden empty staves in the layout but want specific empty staves to appear in some sections, or you want to hide staves with music on them in some layouts.
Procedure
Result
Staff visibility is changed from the selected rhythmic position or system/frame break signpost onwards until the next staff visibility change or the end of the flow, whichever comes first and whether the staves are empty or not.
If a system/frame break signpost did not yet exist at the selected rhythmic position, a system break with your staff visibility settings is inserted at the selected rhythmic position.
