Hope that makes it clearer?
Yes, I understand better, thanks. I'd just suggest changing your
snippet to
\version "2.23.7"
$(let ((notes (ly:music-property #{ <e f g a b c' d' e' f' g' a' b' c'
d'> #} 'elements)))
(make-sequential-music
(map (lambda (x) (ly:music-deep-copy (list-ref notes (random
(length notes)))))
(iota 400))))
with the essential change being the insertion of a
ly:music-deep-copy so it does not share the same music
objects for different notes, which could go wrong with
the application of some music functions.
Cheers,
Jean
