I apologize if I'm re-posting. I've tried twice; I think the attachment was too large.
I'm running LY 2.12.3 under Ubuntu.
I'm trying
to engrave an ossia for two staves, and the the three measure ossia
replaces four measures in the regular staff. I'm attaching an image of
what I'm looking for. I've tried to find a solution in the manual, in
the user list archives, and in the Snippets List, with no luck. I've
been able to get the main staves and the ossia staves, but I can't
figure out how to get three measures in the ossia to match four measures
in the regular staves. I suspect cadenza might help somehow. Can anyone
help?
