the following example (which might work on 1.6 too, if
you strip some of the ly: prefixes) puts 3/4, 9/8 and 10/8
aligned per measure:
#(define (scale-one-music m fraction)
"Maybe we should just export Music::compress to Scheme?"
(let*
((dur (ly:get-mus-property m 'duration)))
(if (ly:duration? dur)
(let*
((l (ly:duration-log dur))
(d (ly:duration-dot-count dur))
(factor (ly:duration-factor dur)))
(ly:set-mus-property! m 'duration
(ly:make-duration l d
(* (car fraction) (car factor))
(* (cdr fraction) (cdr factor))))))
m))
#(define (scale-music-function fraction)
(lambda (x)
(music-map (lambda (y) (scale-one-music y fraction)) x)))
\score {
\notes \relative c' <
\context Staff= AS {
\time 3/4
c4 c c | c c c |
}
\context Staff= BS {
\time 3/4
\property Staff.timeSignatureFraction= #'(9 . 8)
\apply #display-music \apply #(scale-music-function '(2 . 3))
\repeat unfold 6 { c8-[ c c-] }
}
\context Staff= DS {
\time 3/4
\property Staff.timeSignatureFraction= #'(10 . 8)
\apply #display-music \apply #(scale-music-function '(3 . 5))
{ \repeat unfold 2 { c8-[ c c-] }
\repeat unfold 2 { c8-[ c-] }
| c4. c4. \times 2/3 { c8 c c } c4 }
}
} >
\paper { raggedright = ##t }
}
