Re: Post-Cadenza Music

[Mats Bengtsson]

As far as I can understand, Han-Wen's suggestion was to do
soloPart = \notes{
  ...
  \theCadenzaw
  ...
}

and

accompaniment = \notes{
  ...
  \context DevNull \theCadenza
  ...
}

and since there is no such thing as a DevNull context, LilyPond should
just ignore the cadenza music when typesetting the accomaniment.
However, when I try it here, Lily happily typesets the cadenza in
both parts. Fortunately, it's not that hard to implement a DevNull
context yourself. In the syntax of the latest development version,
just add:

\paper{
  \context{
    \type "Engraver_group_engraver"
    \name DevNull
    \consists "Swallow_engraver"
  }
  \context{
    \StaffContext
    \accepts DevNull
  }
}


To get correct MIDI, you have to add the corresponding performer
definitions:

\midi{
  \context{
    \type "Performer_group_performer"
    \name DevNull
    \consists "Swallow_performer"
  }
  \context{
    \StaffContext
    \accepts DevNull
  }
}
