Printing music with different time signatures

In the following snippet, two parts have a completely different time signature, yet remain synchronized.

The bar lines can no longer be printed at the Score level; to allow independent bar lines in each part, the Default_barline_engraver and Timing_translator are moved from the Score context to the Staff context.

If bar numbers are required, the Bar_number_engraver should also be moved, since it relies on properties set by the Timing_translator; a \with block can be used to add bar numbers to the relevant staff.

global = {
  \time 3/4 s2.*3 \break
  s2.*3
}

\layout {
  \context {
    \Score
    \remove "Timing_translator"
    \remove "Bar_number_engraver"
    \override SpacingSpanner.uniform-stretching = ##t
    \override SpacingSpanner.strict-note-spacing = ##t
    proportionalNotationDuration = #1/64
  }
  \context {
    \Staff
    \consists "Timing_translator"

  \context {
    \Voice
    \remove "Forbid_line_break_engraver"
    tupletFullLength = ##t

Bassklarinette = \new Staff \with {

  \override BarNumber.break-visibility = #end-of-line-invisible
