All of the elements in a score are routed through hooks you can
redefine.  So you can just redefine your various hooks to do nothing and
then include the file.

The hooks all end in "-handler".  I see

dak@lola:/usr/local/tmp/lilypond$ git grep -e -handler lily/parser.yy
lily/parser.yy: SCM proc = parser->lexer_->lookup_identifier 
("toplevel-book-handler");
lily/parser.yy: SCM proc = parser->lexer_->lookup_identifier 
("toplevel-bookpart-handler");
lily/parser.yy:  ? "toplevel-book-handler"
lily/parser.yy:  : "toplevel-bookpart-handler");
lily/parser.yy: SCM proc = parser->lexer_->lookup_identifier 
("toplevel-score-handler");
lily/parser.yy: SCM proc = parser->lexer_->lookup_identifier 
("toplevel-music-handler");
lily/parser.yy: SCM proc = parser->lexer_->lookup_identifier 
("toplevel-text-handler");
lily/parser.yy: SCM proc = parser->lexer_->lookup_identifier

Guitar barré without text spanner

[Cantus Ornatus]

Hi everyone,

I apologize for the banal request, but I did not find any suggestion.

I use \startBarre and \startHalfBarre, as shown here:
http://lsr.di.unimi.it/LSR/Item?id=952

How is possible using the same notation (of both kinds of barré,
normal and half) without a text spanner, in order to mark barré just
in one point?
Thanks in advance,
Francesco

Is there a way to patch the lyrics tie character?

[Fernando Gil]

Hello to everyone, I'm struggled with the lyrics tie character when using
an alternate font from Music Type Foundry.

Since lilypond uses character from the music font, when using an alternate
font with the character missing, it doesn't show.

I have a workaround that goes like this:

Cuer -- \markup {po\hspace #-0.3  \override #'(font-name . "emmentaler-20")
\char ##xe196 \hspace #-0.3 y}

But when transcribing 8 stanzas there's certainly much better to use the
simplicity of "~" (i.e. Cuer -- po~y) rather than my workaround.

I imagine there's a chance to achieve what I'm looking with a cleaner way
but have no clue where to start. Hope you can help me. Thanks in advance.

Help with Midi

[David Sumbler]

When working on a project in Lilypond I usually set things up to
generate midi files as well as printable output, mainly for note-
checking.  But it is interesting to generate an ensemble midi file too.
I play these files with TiMidity, using the fluidr3_gm soundfont.

I know the (very) basics about midi instruments (although I'm a bit
vague about midi channels), and I know how to improve things by using
timidity to generate wav files which I can import into qtractor or
similar and then edit the combined result.

What I am about to ask is not really a Lilypond question at all (at
least, I don't think it is), but I am hoping that somebody on this list
can point me in the right direction.  Clearly I am not making the right
searches on line, because I have never managed to find the information
I want.

What I should like to know is
1) how can I use drum and other untuned percussion sounds?
2) I notice that fluidr3_gm has dozens - probably hundreds - of extra
sounds and instruments beyond the standard 128.  How can I access
these?
3) how can I use other soundfonts?  There seem to be a lot of free
soundfonts available on line, but I have no idea how I would use them. 
It would be nice to have a decent trumpet sound (the fluidr3-gm one is
very poor), the sound of violin section as will as solo violin, string
harmonics, timpani roll and so on.

Can anyone point me to a useful online source of such information?

David

Re: Guitar barré without text spanner

Hi Francesco,
How about a simple markup? E.g.:

\version "2.20.0"

half = \markup\concat\fontsize #-5 { \raise #.6 "1"\raise #.2 "/"  "2"
\hspace #.2 }

{
  \clef "G_8"
  
  -\tweak X-offset #-2.5
  ^\markup\concat\tiny {
\half "C" \hspace #.2 "II"
\magnify #0.5 { \lower #.1 " ┐" }
  }
}

HTH, cheers,
Pierre

Which invention are you interested in? I have lilypond source for
invention no.8, which I transcribed from a score I found on IMSLP.

Hi List,

I have a score with repeats and irregular alternate endings. I can neatly

Not exactly what you asked for, but one possible approach is to use tags.

Tags allow for conditional use of material.

In this case, you would add a tag that is specific to MIDI 
and put the repetitions in a similar way you did in the "manual" version.

Then, have two different scores, one for PDF and one for MIDI, 
which use different tags.

Even in the printed score, you need to use the \keepWithTag command, 
even though there is no PDF-specific content here, 
in order to keep the MIDI-tagged content out.

Note that the tag names "MIDI" and "PDF" are just arbitrary words, 
there is no intrinsic significance to them.

This approach becomes handy when coding other differences for MIDI, 

such as fermatas, breaths, rit/accel, trills.

 

\version "2.19.81"


body = { c'4 c' c' c' }
voltaI = { d'4 d' d' d' }
voltaII = { e'4 e' e' e' }
voltaIII = { g'4 g' g' g' }

music = {
  \repeat volta 5 \body
  \set Score.repeatCommands = #'((volta "1."))
  \voltaI 
  \tag #'MIDI { \body }
  
  \set Score.repeatCommands = #'((volta #f) (volta "2. 3. 4.") end-repeat)
  \voltaII
  \tag #'MIDI { 
  \body \voltaII
  \body \voltaII
  \body }

  \set Score.repeatCommands = #'((volta #f) (volta "5.") end-repeat)
  \voltaIII
  \set Score.repeatCommands = #'((volta #f))
  \bar "|."
}

\score {
  \keepWithTag #'PDF \music
  \layout { }
}

\score {
  \keepWithTag #'MIDI \music
  \midi { }
}
