Re: Using Scheme

[Trent Johnston]

Thanks for your help Paul, but I was actually looking at Beam settings

a way to simplify \once \override Beam #'positions = #'( number . number )

I used the padText as an example but couldn't get it to work with the above
example...

| To possibly help with your question 'padding' in the first line
|
| padText = #(define-music-function (parser location padding) (number?)
|
| indicates a numerical variable as reinforced by the '(number?)'
| You can add more variables (say var2) by adding it/them after the position
of 'padding'
| and changing (number?) to (number? number? ... )
|
| var2 would be referred to in the code as $var2
