Re: multimeasure rest bug?

[Mats Bengtsson]

It seems that you spend large efforts on scaling all durations, just to 
be able to obtain the desired time signature. The same result can be 
obtained much easier as shown in the following examples. Also, the 
solution to your multimeasure rest problem is probably easiest to solve 
by changing the measure length used internally by LilyPond:

\version "2.12.0"

global = {
 \key c \major
}

right = \relative c'' {
 \global
 \override Score.TimeSignature #'style = #'mensural
\time 4/4
 \set Timing.timeSignatureFraction = #'(3 . 4)
a4 g f g
\bar":"
\once \override Score.TimeSignature #'stencil = ##f
\time 3/1
a2 a b c b1 a g2 f1 e2
}

left = \relative c' {
 \global
R1 d2 d d a g a c  b1 a  c2
}


\score {
 <<
   \new PianoStaff \with {
     instrumentName = "Organ"
   } <<
     \new Staff = "right"\right
     \new Staff = "left"  \left  >> >> }



Here's an alternative solution that doesn't use \time at all, but only 
sets the relevant properties directly, instead.

\version "2.12.0"

global = {
 \key c \major
 \override Score.TimeSignature #'style = #'mensural
 % This one is used to select the printed time signature:
 \set Timing.timeSignatureFraction = #'(3 . 4)
}

right = \relative c'' {
 \global
%\time 4/4
 % Only change the measure length:
 \set Timing.measureLength = #(ly:make-moment 4 4)
a4 g f g
\bar":"
\once \override Score.TimeSignature #'stencil = ##f
%\time 3/1
 \set Timing.measureLength = #(ly:make-moment 3 1)
a2 a b c b1 a g2 f1 e2
}

left = \relative c' {
 \global
R1 d2 d d a g a c  b1 a  c2
}


\score {
 <<
   \new PianoStaff \with {
     instrumentName = "Organ"
   } <<
     \new Staff = "right"\right
     \new Staff = "left"  \left  >> >> }
