Valentin,
I've made a short snippet here that shows what appears to me to be the
central issue:
% When \override is applied to a tie that is in parallel music, it is
% unclear as to which tie the \override will apply.
% The outcome appears to be somewhat arbitrary.
% Also, note that the documentation says that \overrides apply to all
% music at the same moment, which appears not to happen with ties.
\context Staff {
\context Voice {
\relative c'{
<<
% here the override applies to the tied d's, as the f tie
% is unchanged
{ d2 ~ d }
\once\override Tie #'control-points =
#'((1.75 . -0.5) (2.5 . 0.75) (8 . 2) (13.5 . -1.2))
{ f2 ~ f }
>>
<<
% here the override applies to the tied f's, as the d tie is normal
\once\override Tie #'control-points =
#'((1.75 . -0.5) (2.5 . 0.75) (8 . 2) (13.5 . -1.2))
{ d2 ~ d }
{ f2 ~ f }
>>
<<
% here the override applies to the tied d's, as the f tie
% is unchanged
\once\override Tie #'control-points =
#'((1.75 . -0.5) (2.5 . 0.75) (8 . 2) (13.5 . -1.2))
{ f2 ~ f }
{ d2 ~ d }
>>
}
}
}
HTH,
Carl
