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.

\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,
