Re: Can't use NoteNames twice in score block ??

[Michael Ellis]

Carl, thanks for taking the time to figure it out!  I really appreciate the help. It's good to know there's a workaround.

I'm undertaking a project to produce files containing all the Bach Chorales with solfege syllables (movable Do, La-based minor) under each part.  I'm starting with the MusicXML files created by Margaret Greentree at www.jsbchorales.net.  It turns out that MusesScore can be run in batch modes to produce LilyPond files.  I was able to convert all 400 of them in about 10 minutes of run time.  

The mechanism for producing the solfege syllables is fairly well resolved.  I adapted an example from Valentin ( see http://stackoverflow.com/questions/4378228/lilypond-extracting-pitch-names-from-music ) that uses a scheme function to work around another NoteNames problem: default reversion to dutch pitch names.

To apply it to the chorale files, I just need to put the dutch to solfa mapping and the scheme function at the top of each file and in the score block, call the NoteNames engraver like so:

    \context NoteNames = NNS \with {

       \override NoteName #'stencil = #solfaNames

    } { transpose fa do \Snotes }

where the transposition is from the original key signature back to C major to produce movable Do solfa.

Putting this together with your workaround produces the code and output shown below.  This works quite well.  So the issue I'm wrestling with now is whether it's feasible to automate the editing of 400+ files to separate the clef and instrument names from the notation, detect the original key, and rewrite the score block to produce the desired results.  

Thanks again for your help and any suggestions for how proceed with the automation are more than welcome.  

Cheers,
Mike

Mike,

The problem is apparently that the \clef command implicitly creates some
kind of staff context if it's in a NoteNames context.

If you take the \clef commands out of the music passed to the NoteNames
context, then things seem to work right.  (I haven't fully tested the
instrumentName to see if it can be part of the NoteNames context or not).

Here's some code that works:

\version "2.12.3"

Snotes = \relative c' {

 \time 4/4
 \partial 4
 a'4 |

 bes4 a g d' |
}

Bnotes = \relative c {

 \time 4/4
 \partial 4
 d4 |

 g4 a bes a8 g |
}

ASvoiceAA = {

 \set Staff.instrumentName = #"Soprano"
 \clef treble
 \key f \major

 \Snotes
}


ABvoiceDA = {

 \set Staff.instrumentName = #"Bass"
 \clef bass
 \key f \major

 \Bnotes
}


\score {
 <<
   \new Voice = ASVoiceAA  { \ASvoiceAA }
   \new NoteNames = NNS  {\Snotes}

   \new Voice = ABvoiceDA {\ABvoiceDA}
   \new NoteNames = NNB {\Bnotes}
 >>
}%% end of score-block


HTH,

Carl
