Dear Gilles,
thanks for Your tipp! But I tried it with an own example, that does not work,
I don't know why:
\include "rhythmen.ly"
sax = #(define-music-function (parser location musicA musicB musicC)
(ly:music? ly:music? ly:music?)
#{
\set tupletSpannerDuration = #(ly:make-moment 1 4)
\times 4/5 \makeRhythm $musicA "16 16 16 16 16"
\unset tupletSpannerDuration
\makeRhythm $musicB "4"
#})
\new Staff \relative
{
\sax { c d e f g } a
}
It's because you define a function with 3 arguments musicA, musicB, musicC and
you give only 2 arguments in
\sax { c d e f g } a
If you only want 2 arguments, you have to define sax like that :
sax = #(define-music-function (parser location musicA musicB)
(ly:music? ly:music?)
etc ...
Just delete musicC and a ly:music?.
Gilles
