Hi Mark thanks for the reply,
so my mwe didn’t show, but the measure is 2/5 which means the duration of
the measure is that of a half note prolated by 5:4, so that is where the 8
in 9:*8* comes from.
Regardless of this discrepancy, lilypond is perfectly happy to display
"incomplete" tuplets. see:
\tuplet 3/2 {
c'4.
}
so I don’t believe the issue is that the outermost tuplet is not filled
*completely*, rather it seems to be a problem that the outermost tuplet is
filled *with only one tuplet*. Your example displays the sub-tuplet because
the outermost tuplet contains more than a single tuplet. If we replace your c'4
c' c' with a separate tuplet, everything behaves as expected as well. Well,
I should say that my assertions as to why the other examples work correctly
is a guess.
regards,
g.r.e.
p.s. Again to clarify for anyone following this discussion, it is the
innermost tuplet bracket that disappears for me.
