That's nonsense. Voices in a << ... \\ ... \\ >> construct are not anonymous but named "1", "2", "3" by default, and you can refer to those.

You can just create something like (define context-id (make-object-property)) And then you can set! and fetch (context-id ctx). -- David Kastrup _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
