Right :)
Ok, tried to substitute "add-score" with "print-book-with-defaults" but I
didn't see any midi file in the default folder. But
print-book-with-defaults works for midi output?
This is the code I tried:
\version "2.19.82"
test = #(define-void-function (music filename) (ly:music? string?)
#(print-book-with-defaults
#{
\book {
\bookOutputName $filename
\score $music
\midi{}
} #} ) )
\test {a b} "MyFile"
Thank you, g.
