Should the MWE below work? If it doesn't how do I engrave the percent symbol for a workaround?
(My understanding of the internals docs is weaker than it should be.)
TIA,
Paul
\version "2.20.0"
xNotes = { \repeat percent 4 c''1 }
\addQuote qx \xNotes
yNotes = { \cueDuring qx #up R1*4 }
\score{ \yNotes }
