Hi group.
I'm trying to construct a certain volta ending where there is a first and
second ending, but the first ending does a D.S. to the sign, while the the
second ending is a multiple repeat for solos. I seem to have made it render
correctly, but I keep getting this error. Hopefully this is enough code:
warning: already have a volta spanner, ending that one prematurely
[64]
DSalCoda = {
\once \override Score.RehearsalMark.self-alignment-X = #RIGHT
\mark \markup "D.S. al Coda"
}
voltaSolos = \markup { "2, 3, 4 . . ." }
\alternative {
{
s1
\DSalCoda
\bar "||"
}
{
\set Score.repeatCommands = #(list (list 'volta voltaSolos)
'start-repeat)
s1
\bar ":|."
}
}

Hi Stan,
(1) %%%%%%%%%%%%%%%%%%%
In general, the settings accepted in the argument-list for
repeatCommands may manually create repeats with or without alternative
endings.
Drawback: \unfoldRepeats doesn't work on those manual settings. See
the following example where simple repeats are done (manually and via
\repeat volta ...):
\unfoldRepeats
\relative {
c''1
\set Score.repeatCommands = #'(start-repeat)
d4 e f g
\set Score.repeatCommands = #'(end-repeat)
c1
\repeat volta 2 { d,4 e f g }
}

If you don't care about midi you could do the following.
Note that 'start-repeat would be used to begin a (new) repeated
section, but _not_ to start an alternative ending. Don't use it here.
\repeat volta 2 { c'1 }
\alternative {
{
d'1
}
{
\set Score.repeatCommands =
#(list
'end-repeat ;; print the ending repeat-bar
'(volta #f) ;; finish first volta
(list 'volta voltaSolos) ;; set text for second volta
)
e'
}
}
Though, in your example you don't want the closing repeat-bar, but \bar "||".
Hence 'end-repeat should be deleted and to ensure a closing first
VoltaBracket use \allowVoltaHook "||" at top-level.
Full example:
\allowVoltaHook "||"
DSalCoda = {
\once \override Score.RehearsalMark.self-alignment-X = #RIGHT
\mark \markup "D.S. al Coda"
}
voltaSolos = \markup { "2, 3, 4 . . ." }
\repeat volta 2 {c4 c c c }
\alternative {
{
c4 c c c
\DSalCoda
\bar "||"
}
{
\set Score.repeatCommands = #(list '(volta #f) (list 'volta voltaSolos) )
c4 c c c
\bar ":|."
}
}

If you need unfoldRepeats, an override may fit better:
\allowVoltaHook "||"
DSalCoda = {
\once \override Score.RehearsalMark.self-alignment-X = #RIGHT
\mark \markup "D.S. al Coda"
}
voltaSolos = \markup { "2, 3, 4 . . ." }
voltaTxt =
\once \override Score.VoltaBracket.before-line-breaking =
#(lambda (grob) (ly:grob-set-property! grob 'text voltaSolos))
%\unfoldRepeats
\repeat volta 2 {c4 c c c }
\alternative {
{
c4 c c c
\DSalCoda
\bar "||"
}
{
\voltaTxt
c4 c c c
\bar ":|."
}
}
