Timing.baseMoment behaviour

2011-02-26 Thread Jean-Charles Malahieude 

Hi,

While translating the commit "Doc -- Clarify instructions on autobeam
settings" I wanted to understand what was illustrated, but



texidoc = { Timing.baseMoment does not always work }

\score {
  \new Staff {
\time 2/4
\set Timing.baseMoment = #(ly:make-moment 1 16)
\set Timing.beatStructure = #'(3 3 2)
a'16^"works" \repeat unfold 7 { a'16 }
  }
}
\score {
  \new Staff {
\time 6/8
\set Timing.baseMoment = #(ly:make-moment 1 16)
\set Timing.beatStructure = #'(3 3 2 3 1)
a'16^"works" \repeat unfold 11 { a'16 }
  }
}
\score {
  \new Staff {
\time 3/4
\set Timing.baseMoment = #(ly:make-moment 1 16)
\set Timing.beatStructure = #'(3 3 2 3 1)
a'16^"does not work" \repeat unfold 11 { a'16 }
  }
}

You also need to clear beamExceptions:

\score {
  \new Staff {
\time 3/4
\set Timing.baseMoment = #(ly:make-moment 1 16)
\set Timing.beatStructure = #'(3 3 2 3 1)
\set Timing.beamExceptions = #'()
a'16^"works" \repeat unfold 11 { a'16 }
  }
}

I find it strange that this clearing is mandatory only with 3/4, and had 
preferred the snippet to contain it, since whatever you try to 
understand and explain this "known issue" it wont work. Nevertheless, 
I'll add it to the French version.

I think it's generally recommended to clear beamExceptions when you are 
changing the beaming.  However, it's not always a problem if you don't.
