Re: Tie control-points delete another tie

[Trevor Daniels]

It seems that the tie override is sensitive to the
order in which the two parallel sections appear.
If the order is reversed so the override is in
the first section, and explicit voices are used,
it works as expected with ties.  But you were
right originally, this is either a bug or LilyPond
is overly sensitive.  FWIW, here's a version with
ties that does what you want:

\new Staff <<
  \key f \major \time 6/8
  \new Voice <<
    \stemUp
    \relative c' {
      fis4. fis4 a8
      \once\override Tie  #'control-points =
      #'((1.75 . -0.5) (2.5 . 0.75) (8 . 2) (13.5 . -1.2))
      fis4. ~ fis4 a8
    }
    \relative c'' {
      d4. ~ d4 e8
      d4. ~ d4 e8
    }
  >>
  \new Voice {
    \stemDown
    \relative c'' {
      a8 a16 a a8 a a a
      a8 a16 a a8 a a a
    }
  }
