ANSWER, Re: problem with full-measure rests in differently time-scaled staves

[Adam James Wilson]

I answered my own question: it turns out if I set the \time  of the
offending staff to ["global" voice \time * crosspulse ratio] - in this
case 3/8 * 4/9, or 1/6, the full measure rests appear correctly in the
lower staff.  This gives a time signature of 1/6, but this can easily
be replaced with a "dummy" 3/8.  Solution below.

\version "2.11.32"

#(set-global-staff-size 8)

\paper {        
        ragged-right = ##t
}
\layout {
        \context { \Score
                \remove "Timing_translator"
                \remove "Time_signature_engraver"
                \remove "Default_bar_line_engraver"
                \override SpacingSpanner #'uniform-stretching = ##t
                \override SpacingSpanner #'strict-note-spacing = ##t
                proportionalNotationDuration = #(ly:make-moment 1 64)
        }
        \context { \Staff
                \consists "Timing_translator"
                \consists "Time_signature_engraver"
                \consists "Default_bar_line_engraver"
        }
}
                        
global = { \set Timing.defaultBarType = ""
                   \repeat unfold 4 { s4. } \bar "" \break
                 }

\new Score { <<
        \new StaffGroup { <<
                \new Staff <<
                        \global
                        {
                        \time 3/8
                        \repeat unfold 4 { R4. \bar "|" }
                        }
                >>
                \new Staff <<
                        \global
                        {
                        \compressMusic #'(4 . 9) {
                                \time 1/6
                                \repeat unfold 9 { R4. \bar "|" }
                                }       
                        }
                >>
        >> }
        
>> }
