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 }
