Dear LilyPonders,
while trying to typeset some vocal music I encountered some
difficulties with \autoBeamOff:
1) \autoBeamOff has no effect on other voices when used in a global
variable/ghost voice. It has to be turned on explicitly for each
voice. This is probably intentional but AFAIK not mentioned in the docs.
2) \autoBeamoff shows strange effects in combination with 16th notes
and \partcombine. \autoBeamOff only effects 16th notes when they
happen to be in the first measure of a combined part. All following
measures containing 16th notes are beamed automatically as if
automatic beaming had been turned on again. This looks like a bug to
me!? (No problems with \autoBeamOff in standard polyphonic notation)
In combination with \autoBeamOff \partcombine seems to require some
curly braces, e.g.:
\partcombine { \autoBeamOff\MusicPartOne } { \autoBeamOff
\MusicPartTwo }
I didn't find this information in the docs.
Here's an example (please uncomment/comment the first measure in each
variable):
\version "2.13.30"
global = {
\time 2/4
\key f\major
\autoBeamOff
%s2
s2
}
Soprano = {
%f'8 f' f' f' |
g'16(a'16) bes'16 (g'16) f'16 (e'16) d'16(e'16) |
}
Alto = {
%f'8 f' f' f' |
d'4 bes8 bes8 |
}
\score {
\new Staff = "SopranoAlto" <<
\new Voice = "globalSettings" {
\global
}
\partcombine %\Soprano\Alto
%\autoBeamOff\Soprano
%\autoBeamOff\Alto
{ \autoBeamOff\Soprano }
{ \autoBeamOff\Alto }
>>
\layout {
\context { \Staff
printPartCombineTexts = ##f
}
}
}
