Hi Vaughan,
if global is a music-function calling autopan, it will evaluate it
everytime. If global is a variable, its value is set, once it is assigned.
So if you have to wrap it in music-function. If you always have a
variable "global" containing all you need, you can wrap that in a function:
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
music = { c'' }
global = { \time 4/4 }
% another name than "global"!
meta =
#(define-music-function (parser location)()
#{
\autopan \global
#})
\new Staff <<
\meta
\music
>>
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
"global" is only a function, if it is declared one. Otherwise it is just
a variable.
BTW, nice autopan utility ;)
HTH, Jan-Peter
