Re: setting the beatlength for sixteenth-sixtuplets

[Stefan Thomas]

Well, I found a solution, but I thought, there would be an easier solution.
\version "2.12.2"
ST = #(define-music-function (parser location x) (ly:music?)
#{
 #(override-auto-beam-setting '(end 1 24 * *) 1 8)
  #(override-auto-beam-setting '(end 1 24 * *) 2 8)
   #(override-auto-beam-setting '(end 1 24 * *) 3 8)
 #(override-auto-beam-setting '(end 1 24 * *) 4 8)
  #(override-auto-beam-setting '(end 1 24 * *) 5 8)

   #(override-auto-beam-setting '(end 1 24 * *) 8 8)
    #(override-auto-beam-setting '(end 1 24 * *) 9 8)
     #(override-auto-beam-setting '(end 1 24 * *) 10 8)
      #(override-auto-beam-setting '(end 1 24 * *) 11 8)
       #(override-auto-beam-setting '(end 1 24 * *) 12 8)
  \set tupletSpannerDuration = #(ly:make-moment 1 8 )
  \times 2/3 { $x } 
    #(revert-auto-beam-setting '(end 1 24 * *) 1 8)
#(revert-auto-beam-setting '(end 1 24 * *) 2 8)
#(revert-auto-beam-setting '(end 1 24 * *) 3 8)

#(revert-auto-beam-setting '(end 1 24 * *) 6 8)

Dear Paul,
I would like to have the Sixtheenth-Triplets beamed in groups of three, altough when there is a 2/2 bar, e.g..

Ah!

I haven't taken the time to understand auto beaming rules yet.  I usually just manually beam some of the notes and the rest seem to follow along:

\set tupletSpannerDuration = #(ly:make-moment 1 8)

\times 2/3 { a16 b a b[ a b] a b a b[ a b] }

Maybe now would be a good time for me to learn this.

Are you saying there isn't an auto-beaming solution for you?

       Dear community,
       I would like to define a function, that allows me to set the
       beat-length to 1/8 for 16th-triplets.  And I would like, if it
       could work for every kind of bar.
       I tried it with:
       \version "2.12.2"
       SSX = #(define-music-function (parser location x) (ly:music?)
       #{
         \set beatLength = #(ly:make-moment 1 8)
        \set tupletSpannerDuration = #(ly:make-moment 1 8 )
        \times 2/3 { $x }
        \unset tupletSpannerDuration
        \unset beatLength
       #})

       \relative c' {
        \SSX { c16 d e f e d e f g a g f a b c d c b }
       }


   I don't know if I'm missing the desired functionality but this is
   what I do.  It may or not be as easy as what you want.

   esTuplets = \set tupletSpannerDuration = #(ly:make-moment 1 8)
   eeTuplets = \set tupletSpannerDuration = #(ly:make-moment 1 4)
   eqTuplets = \set tupletSpannerDuration = #(ly:make-moment 1 2)

   %The second letter is *s*ixteenth, *e*ighth, *q*uarter

   I just execute the one I want for the code which follows it.

   Forgive me if I'm not understanding your need.
