Hey all,
I came up with a hack that more or less works - I'm still working on the
scaling, but I think the shape is right:
\version "2.15.16"
\relative c'' {
\override NoteHead #'stencil =
#(ly:stencil-translate (make-connected-path-stencil
'(
( 56 0 109 -29 109 -91 )
( 109 -163 53 -212 6 -240 )
( -30 -261 -70 -276 -111 -276 )
( -167 -276 -220 -247 -220 -185 )
( -220 -113 -164 -64 -117 -36 )
( -81 -15 -41 0 0 0 )
)
0.01 0.0040 0.0040 #f #t) '(0 . 0.5))
a4
}
Cheers,
MS
