If you ever work in 12/8 time, you may have discovered that there is no default way to tell Sibelius to group the “macro” beats 1 & 2, or 3 & 4, into a single dotted half (dotted minim) rest.
Enter Michael Eastwood’s plug-in, which does one thing, and does it well:
Dotted Minim Rests only operates in 12/8, looking for any sequence of rests on the first or third beats of the bar and turning them into a single dotted minim rest. The plug-in will thus convert two dotted crotchet rests into a single dotted minim rest, a convention that some people prefer.
In other words, it turns all instances of this:
If you can live with seeing the defaults until you finalize your score, you can run the plug-in once near the end of your workflow, and it will work in all appropriate instances.
You can download it here or directly though Sibelius: File > Plug-ins > Install Plug-ins > Notes and Rests > Dotted Minim Rests.
