Is it possible to override trill pitch note heads in the shape of a (diamond) natural harmonic?
This attempt ...
\version "2.19.17"
\language "english"
\new Staff {
\override TrillPitchHead.style = #'diamond
\pitchedTrill
c'4 \startTrillSpan cs'
d'4 \stopTrillSpan
e'4
f'4
}
### END ###
... prints no trill pitch note head at all:
GNU LilyPond 2.19.17

Preprocessing graphical objects...
programming error: must have stem dir for note head
continuing, cross fingers
tmp.ly:8:9: warning: none of note heads `noteheads.s' or `noteheads.d' found
c'4
\startTrillSpan cs'
Does anyone have a workaround? (I'm wanting the sort of mixed trill possible between an open string and one of the string's harmonic nodes, standard as per Saariaho, Sciarrino and so on.)
