Re: Temporarily override frenched score

[Aberforth D - Instrumentals]

Thanks for this insightful clarification. I'll just take care not to apply it to the first or last bar on a staff. A minimum of 3 bars per staff should not be a real limitation.

Regards,

The reason seem to be that setting keepAliveInterfaces at a line-break
point affects both systems that participate.

For example:

%%%%
\version "2.20.0"
\language "english"

\layout {
   \context {
     \Staff
     \RemoveAllEmptyStaves
   }
}

%% => http://lsr.di.unimi.it/LSR/Item?id=312
showMultiRests = {
  \set Staff.keepAliveInterfaces = #'(
     rhythmic-grob-interface
     multi-measure-rest-interface
     lyric-interface
     stanza-number-interface
     percent-repeat-interface)
}
hideMultiRests = \unset Staff.keepAliveInterfaces

fillBar = \relative c' { g'8[ g g g g g] | }
fillLine = { \fillBar \fillBar \fillBar \fillBar }

partA = {
   \key d \major \time 6/8 \clef "G"
   R2.*4 \break
   R2.*4 \break
   \showMultiRests R2.*4 \break \hideMultiRests % Affects 3 systems
   R2.*4 \break
   R2.*4 \break
   R2.*4 \break
   R2.*4 \break
   R2. \showMultiRests R2.*2 \hideMultiRests R2. \break % Affects only 1
system
   R2.*4 \break
}

partB = {
   \key d \major \time 6/8 \clef "G"
   \repeat unfold 9 \fillLine
}

\score {
   <<
   \new Staff \with { shortInstrumentName = "Pt A" } \partA
   \new Staff \with { shortInstrumentName = "Pt B" } \partB
   >>
}
%%%%

I do not know if there is an elegant way to change this behaviour.
