Pretty happy with how that looks, but now I'm having trouble
converting it to a function. The following is what I've put together,
but I can't seem to shake the compiler error.
The parameters feather-ratio, tuplet-ratio are not moments, but ratios.
Also, the parser and location arguments have not been required for
several releases of LilyPond. Here is a working version of your function.
\version "2.24.2"
customTuplet = #(define-music-function
(displayed-note y-off beam-left tuplet-up feather-ratio tuplet-ratio
notes)
(number? number? boolean? boolean? rational? pair? ly:music?)
#{
\once \override TupletNumber.text = \markup { \note-by-number
#displayed-note #0 #UP }
\once \override TupletBracket.bracket-visibility = ##t
\once \override TupletBracket.visible-over-note-heads = ##t
\once \override TupletBracket.Y-offset = #y-off
\once \override Beam.grow-direction = #(if beam-left LEFT RIGHT)
#(if tuplet-up
#{ \tupletUp \tuplet #tuplet-ratio {
\featherDurations #feather-ratio { $notes }
} #}
#{ \tupletDown \tuplet #tuplet-ratio {
\featherDurations #feather-ratio { $notes }
} #}
)
#})
\score {
\relative c'' {
\time 4/4
\customTuplet #1 #-1.5 ##t ##t #2/1 #'(6 . 8) {
d16[-. d-. d-. d-. d-. d]-.
}
\customTuplet #2 #-1.5 ##f ##f #2/1 #'(5 . 8) {
e16[-. e-. e-. e-. e-. e]-.
}
}
}
