polyrhythm with multiple tempi

[Kieren MacMillan]

Hi all,

Please consider the following snippet:

%%%  SNIPPET BEGINS
\version "2.19.83"

\layout {
  \context {
    \Score
    \remove "Timing_translator"
    \remove "Default_bar_line_engraver"
    \remove "Metronome_mark_engraver"
  }
  \context {
    \Staff
    \consists "Timing_translator"
    \consists "Default_bar_line_engraver"
    \consists "Metronome_mark_engraver"
  }
}

slower = {
  \tempo 4=80
  \scaleDurations 120/80 { \repeat unfold 12 { c'4 } }
}

faster = {
  \tempo 4=120
  \repeat unfold 16 { c'4 }
}

\score {
  <<
    \new Staff \slower
    \new Staff \faster
  >>
}
%%%  SNIPPET ENDS

The polyrhythm stretches out and lines up as expected, but I can’t seem to get 
the barlines to offset [despite moving the engravers I thought were required]. 
Corrections/hints appreciated.

Thanks,
Kieren.
