Re: Getting rid of redundant tuplet brackets in combined voices

[Henrik Frisk]

Hi,

Unfortunately I couldn't compile your file (LilyPond exits with
segmentation fault or bus error) - this is in Lily 2.9.13.

However, I would imagine you could put a 

\override Voice.TupletBracket  #'bracket-visibility = ##t
\override Voice.TupletNumber #'transparent = ##t

before your \times statement in your \tupletsII voice. I would also imagine you 
could put that
before your \tupletII include in the VoiceII.

But, I haven't tried it...

best,

Henrik
