I have a problem that’s somewhat the opposite of this thread: https://www.steinberg.net/forums/viewtopic.php?t=104770
In a piece that alternates between sections in 7/8 and sections in 4/4, it happens that a system ends in 7/8, jumping via Dal Segno into a section in 4/4. The next system is the Coda which is again in 4/4.
Here’s a trivial (if idiotic) example to illustrate the situation:
How can I get a cautionary 4/4 signature at the end of the system to remind the musicians of the upcoming change?
