Sorry about that, read the first part of what you provided, not all.
I just figured it out. I was essentially outputting sequentially instead of
simultaneously. I didn't figure it out until I added about two or three
copies of the music to run the lyrics out.
The stripped-down function is:
seqVerses =
#(define-void-function (parser location up down lyrics)
(ly:music? ly:music? string? string? string? scheme? scheme? scheme? list?)
(let*
((score
#{
\score {
<<
\new Staff="top" { $up }
#(make-simultaneous-music (map ly:music-deep-copy lyrics))
\new Staff="bottom" { $down }
>>
}
#}
)
)
(add-score parser score)
)
)
This takes the lyrics (or practically any list of musical expressions) and
spits them out in-between the two staves. This lets me define simultaneous
lyrics as a single list element and they'll be preserved in the split-verse
version (in the case of choruses where there are multiple parts).
Thanks for the assistance. I think that gets everything I was looking for.
Cheers,
Carl
