Sure.  add-score wants a score and you feed it a book.  Maybe you want
print-book-with-defaults instead?

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?)
       \book { 
         \bookOutputName $filename
         \score $music     
       } #} ) )

\test {a b} "MyFile"

Thank you, g.
