How should beam subdivisions work under tuplets?
\version "2.19.35"
\relative c'' {
\set subdivideBeams = ##t
\set baseMoment = #(ly:make-moment 1/16)
c32 [ c c c \tuplet 3/2 { c c c c c c c c c c c c ]}
}
will create beam subdivisions after the first group of four 1/32s and
another one in the middle of the tuplet group. So the subdivisions come
at the absolute 1/8 positions.
However, shouldn't the subdivisions be rather considering the *written*
durations? That is, shouldn't the second half of the beam be subdivided
in three groups of two notes each (as the two-voice last crotchet suggests)?
If I'm not misinterpreting things this is also *intended*, as the
comment in the code says:
// The rhythmic importance of a stem between beats depends on
its fraction
// of a beat: those stems with a lower denominator are deemed more
// important. For tuplets, we need to make sure that we use
// the fraction of the tuplet, instead of the fraction of
// a beat.
This is even more problematic with rhythms that *should* be subdivided
but where the notes don't fall at the multiples of baseMoment, like in
the second example:
c32 c c c \tuplet 3/2 {
\tuplet 3/2 16 {
c c c c c c c c c
}
(same settings as above)
where I think I would want the second half of the beam subdivided in
three groups with three notes each (of a *written* length of 1/16).
Opinions?
