Re: Tie engraver

[Andrew Bernard]

Hi Urs,

Yes,  a small example always helps. I should have included one to begin with.

The snippet here shows how the up/down behaviour is the default, but when you go into voices the ties are unidirectional. All this is correct, I now understand. What I was wanting was to be able to override the voicing style defaults and tell the engraver to do it ‘my’ way, instead of the ‘proper’ way.

Andrew

\version "2.19.18"

treble = \relative c'' {

  \clef treble

  \time 1/4

  

  <c e g>^\markup { A } ~ <c e g> <c e g c>~ <c e g c>

  <<

    {

      <c e g>^\markup { B } ~ <c e g> <c e g c>~ <c e g c>

    }

    \\

    {

      <c,, e g> ~ <c e g> <c e g c>~ <c e g c>

    }

  >>

}

\score {

  \new Staff { \treble }

  \layout { }

}

Hi Urs and David,

Thanks so much. Yes, my chords are in voices so the slurs all face the same direction accordingly. I was completely unaware of this aspect of engraving. I had better study more scores and order that copy of Behind Bars!

But then the question becomes transformed - can you tell the tie engraver for a voice to override its default behaviour, even though that may be technically incorrect? I have literally several hundred I need to tweak.

No easy way that I know of.  Or, rather, no way that doesn't involve a lot of copied code from various files.  The attached should make life easier, but note that it won't work in at least one construct.

From Andrew's description I'm not 100% clear what he actually means. Maybe everything is much simpler?

Do you mean you don't have <x y > chords at all but polyphonic voices that line up to "chords"?
In that case you can force any of the voices' ties in a direction through \tieUp, \tieDown and \tieNeutral. Which is in the manuals ...

Urs

Best,

David
