I'm not seeing a post from anyone else exactly on this issue, so...
I like the new repeat structure:
https://lilypond.org/doc/v2.24/Documentation/notation/long-repeats#segno-repeat-structure
The example works with the whole note after volta 1, but if you add
more notes, change the rhythm, etc., the pdf doesn't display properly
and MIDI generates a warning and doesn't execute the repeat properly.
If you put curly brackets around the volta 1 section the problem
disappears.
Is this a bug, or am I missing something (as usual).
To explain it by analogy, it's as if you had written
{
\transpose c' d'
a b c' d' e' f' g'
}
and expected \transpose to transpose everything after it.
That's not how it works. Unlike things like \clef and \time,
commands like \transpose, \repeat and \volta apply to
a music argument, so you need to write
{
\transpose c' d' {
a b c' d' e' f' g'
}
}
If you don't put the braces in
\volta 1 a4 a a a
it's as if you had written
\volta 1 {
a4
}
a a a
The notes after the first one are not included in the argument
to \volta, and thus not part of the volta, which makes LilyPond
legitimately confused.
