You can't use a literal list here (with overrides either). Which won't solve the problem, but see below... >> %%%%%%%%%%% >> >> alterBroken has no effect; it gives a warning about ~ not being a spanner. >> Which is wrong – isn’t it? _If_ it isn’t, we should at least add a ‘Known >> issue’ in NR 5.5.5.

Unfortunately, in the case of Ties, span direction.is not set. Try this for a fix: \version "2.19.46" alterBroken = #(define-music-function (property arg item) (key-list-or-symbol? list? key-list-or-music?) (_i "Override @var{property} for pieces of broken spanner @var{item} with values @var{arg}. @var{item} may either be music in the form of a starting spanner event, or a symbol list in the form @samp{Context.Grob} or just @samp{Grob}. Iff @var{item} is in the form of a spanner event, @var{property} may also have the form @samp{Grob.property} for specifying a directed tweak.") (if (ly:music? item) (if (or (eq? (ly:music-property item 'span-direction) START) (music-is-of-type? item 'tie-event)) (tweak property (value-for-spanner-piece arg) item) (begin (ly:music-warning item (_ "not a spanner")) item)) (let* ((p (check-grob-path item (*location*) #:default 'Bottom #:min 2 #:max 2)) (name (and p (second p))) (description (and name (assoc-get name all-grob-descriptions)))) (if (and description (member 'spanner-interface (assoc-get 'interfaces (assoc-get 'meta description)))) (propertyOverride (append item (if (symbol? property) (list property) property)) (value-for-spanner-piece arg)) (begin (ly:input-warning (*location*) (_ "not a spanner name, `~a'") name) (make-music 'Music)))))) { 1-\alterBroken color #`(,green ,red) ~ \break % or #(list green red) 1 } %%%%%%%%%%%%%% HTH.
