Hi,
it has nothing to do with DevNull or the like, even this boiled down
example comes out wrongly and with bar check failures:
\version "2.19.49"
music =
\repeat volta 2 {
c1
}
\alternative {
{
\time 3/4
d2. |
\time 4/4
c1 |
}
{ d1 | }
}
<<
\relative c'' \music
\relative c' \music
>>
The culprit is the new `alternativeRestores'-context-property.
The default is:
alternativeRestores = #'(measurePosition measureLength lastChord)
measureLength is the problem. You can (once) unset
`alternativeRestores' or delete measureLength from the list.
Leading to:
music =
\repeat volta 2 {
%\set Score.alternativeRestores = #'(measurePosition lastChord)
\unset Score.alternativeRestores
c1
}
\alternative {
{
\time 3/4
d2. |
\time 4/4
c1 |
}
{ d1 | }
}
<<
\relative c'' \music
\relative c' \music
>>
Apart from Changes it's not yet documented, please write a bugreport
requesting documentation, maybe we should rethink the default-settings
as well.
HTH,
Harm
