Hi,
Why do you often find constructs similar to this one in LilyPond's source?
midi.scm line 26:
(define-session-public absolute-volume-alist '())
(set! absolute-volume-alist (append absolute-volume-alist etc.))
line 72:
(define instrument-names-alist '())
(set! instrument-names-alist ...
Is there any difference with (define-session-public
absolute-volume-alist '(...)) ? I suspect there is one since this is
frequent but I can't figure out what the purpose is here.
Best,
Jean Abou Samra
