Hi Kieren,
We have a winner!
Ah, but _this_ you can have with stock LilyPond (because you're still only affecting a single Voice):
\version "2.25.33"
music_only =
\new Staff <<
\new Voice = "sop" {
\voiceOne
c''4 4 4 d''
}
\\
\new Voice = "alt" {
\voiceTwo
c''4 b' a' g'
}
>>
hider = \context Bottom {
s4 \context Voice = "sop" \hideNotes s2 \context Voice = "sop"
\unHideNotes
}
\score {
<< \music_only \hider >>
}
You could probably also simply take "sop" instead of "Bottom".
