Comment #7 on issue 2402 by [email protected]: Extra bar-lines appear
when cadenzas are mixed with time signatures
http://code.google.com/p/lilypond/issues/detail?id=2402
The key piece of the example seems to be, with notes instead of rests,
<< {
{ c''1 d'' \bar "" } {\cadenzaOn e''1 f'' \cadenzaOff }
} \\ {
{ \cadenzaOn c'1 d' \cadenzaOff \bar"||" } { e'1 f' }
} >>
where the e1 f1 were intended to be in cadenza timing with no bar line.
The program generating this type of LilyPond input seems to expect that
either the invisible bar, or the extra {}, or the pairing of On and Off
will cause the cadenzaOn to come after the cadenzaOff. LilyPond's << >>
simultaneous music construct, however, makes them happen at the same time.
Out of the conflicting simultaneous settings LilyPond obeys the one she
sees (cadenza off and a double bar).
Humans would not write an "off" and "on" to happen at the same time and
affect the same behavior. It seems wisest for the program that generated
this input to change so that it works with LilyPond.
