Hi Simon
Many thanks for the reply.
You were right about the skylines. The debug shows a huge spike above the
first staff on the page. Trouble is, that staff shows only rests for the
measures where the spike occurs, so not sure why the skyline shoots up. The
second staff shows normal skylines, with some notes above the staff and a
triplet mark all properly outlined.
I tried locating the problem, reducing the score to one voice, and commenting
out the lyrics. I then commented out the notes, working back from 160 bars to
just 15, and the problem persisted. Tried commenting out every setting and
override statement to no avail. Finally removed all references to a great long
globalTempo definition that I suppose Rosegarden inserted to regulate the MIDI
output, and BINGO, the score looks fine, with skylines under control.
Thanks again
Cheers

Hi,
first on a technical note: Many do not use the Nabble interface and they
can’t see to which old thread you are replying. It’s more helpful to
just open a new one.

The problem doesn’t ring any bell with me, at least with the empty space
you are referring to. You could try inserting the following line into
your LilyPond file to enable visualisation of the ‘skylines’ LilyPond
uses for spacing:
#(ly:set-option 'debug-skylines #t)
and report back if that gives any hint, maybe as to what grob is causing
the empty space.
Else it’s not possible to say anything without looking at the actual
code. Either you have another go at creating a minimal example, e.g. by
successively replacing music with spacer rests, or using explicit page
breaks, or \repeat constructs. Or you send over the whole file,
privately to me if necessary.
Best, Simon
