Hi Mats
Thanks for your ideas. You proposed three work-arounds :
1. I don't need to switch between french and normal staves (AFAICS).
2. When I use the same staff context, I still get exactly the same
error. In your examples you leave out the lyrics, they are at
the core of the problem. For instance:
- - - -[START]
\version "2.11.60"
\layout { ragged-right = ##t }
\score{ {
\new Staff = soprano \relative c' { c d e f | g1 | }
%\addlyrics{ \lyricmode { Did -- dle did -- dle dum. } }
<<
\context Staff = soprano \relative c'' { g4 f e d | c1 | }
\addlyrics{ \lyricmode { Did -- dle did -- dle dum. } }
\new Staff = solo \relative c'' {g8 c g f e g e d | c1 | }
>>
} }
- - - -[END]
Try uncommenting the first lyric line
3. The third alternative won't do either. The two groups represent
refrain and verse. I use separate variables to be able to use
different content structure in the PDF (Ref. + V1 + V2 + V3) and
in the midi (Ref + V1 + Ref + V2 + Ref. + V3 + Ref). So introducing
additional staves on the fly makes this much more difficult.
Thanks for forwarding this to lilypond-bugs. I wasn't sure whether I
was missing something simple, or whether it really is a bug.
Cheers
