Re: Full bar rests in multi-voiced piano scores -- question and a suggestion

Full bar rests are the biggest issue. It looks like this is the answer I need.

The individual tweaks always need specific attention. That is just the
way music is. Exceptional cases everywhere and then composers invent
new ones! That said, it looks like these tweaks will not be that
difficult to work through.

Arvid's solutions in the next post looks interesting and I'll give it
a try and  see what happens.

Thanks for the help! And since this is scheduled to be made part of
the documentation I'm happy :)
