Hi all,
so: what is the incantation for ly:make-moment to address some point in
a \partial ?
Modifying David's snippet below to
\version "2.19.30"
{
\partial 4
\once \override NoteHead.after-line-breaking =
#(lambda (grob)
(display (grob::when grob))
(newline))
c''4
d''1
}
returns
#<Mom 0>
so nothing that would help me construct the proper make-moment call.
Any help? TIA Urs
