The \retrograde function doesn't seem to handle ties at all, as seen in
this example, which engraves only one tie:
music = { c'4~ c'8 g'8 }
\new Staff {
\music
\retrograde \music
}
The notation manual mentions that "manual" ties are not handled, and
suggests that "some" ties can be generated automatically instead, by
entering longer notes and using automatic note splitting to break them at
bar lines. But that doesn't work for me, because I have a note made up of
a quarter and a sixteenth tied together across the middle of a bar, not
across a bar line. Does someone perhaps have a snippet that will do
retrograde with correct handling of this kind of tie?
If anything, I would have thought something like this would work:
%%%%%%%
\version "2.19.45"
music = \context Bottom <<
{ c'4*5/4 d'16 e' f' }
{ s4 \bar "" s }
>>
\new Staff {
\music
\retrograde \music
}
\layout {
\context {
\Voice
\remove "Note_heads_engraver"
\consists "Completion_heads_engraver"
}
}
%%%%%%%%
But in fact this doesn’t split the notes. I recall that I have been
having problems with invisible bar lines triggering
Completion_heads_engraver, and I tried to make advantage of that, but
Lily doesn’t cease to surprise you…
Best, Simon
