Hi Robert,
Try:
%%% BEGIN %%%
\version "2.25.19"
example = \relative c''
{
\clef treble
\key f \major
\time 5/4
<<
\new Voice {
\voiceOne
\stemDown 2 \stemNeutral 4 2
}
\new Voice {
\voiceTwo
% \after 2 \< \after 8*7 \!\> \after 2 \!% <== old
>
> % \after 2 \< \after 8*7 \!\> \after 2 \!
> s2 d8(c b2)
Make that
s2 d8(\< c \after 8 \> b2) <>\!
\after doesn't work the way you indented your code suggests you
think it does. The syntax is
\after DURATION ARTICULATION MUSIC
and gives something roughly equivalent to
<
