Dear community,
I would like to define a variable with sheme and I want to substract the
number one from this variable.
I tried it with:
% the following defines a Slur, lasting a certain number of eigth-notes
> xaS = #(define-music-function (parser location x) (number?)
> #{ % in der folgenden Zeile Lilypondcode eingeben
> s1*0 ( \repeat unfold #(- $x 1) {s8 } s8)
> #})
>
Unfortunately without succes!
