Because lilypond "doesn't expect" to return more than one score I tried to
put the call to my function returning the score inside a \book. But this
also does not work and I get this error:
Starting lilypond-windows.exe 2.19.81 [Untitled (2)]...
Processing
`C:/Users/GIANMA~1/AppData/Local/Temp/frescobaldi-wrdtmre8/tmppoxiemgd/

<0>: error: bad expression type
\myScore {\repeat percent 2 {c' d' e' f'}}
[...]
I don't understand why the previous error.
This is my code:
\version "2.19.81"
myScore = #(define-scheme-function (music) (ly:music?) #{
\score { $music \layout{} }
\score { \unfoldRepeats $music \midi{}}
}
#})
\book {
\myScore {\repeat percent 2 {c' d' e' f'}}
\myScore {\repeat percent 2 {g c' c' c'}}
}
Thank you, g.
