Re: Problem with Percent repeats

[Joshua Nichols]

Thank you for your speedy reply and candor. I appreciate this, as now I can look forward to seeing improvements with an already stellar program and tinker with the "moment" at the same time! Thanks again!

IC,

Josh

It turns out that emulating the broken part is somewhat feasible.


  {
    \time 5/16  a16\<[ r c-> r a]
    \time 4/16  c16->\! r r8 \mark \markup { \box 191 }
  }
  \omit\time 9/32
  #(make-music 'DoublePercentEvent
    'length (ly:make-moment 9/16))
  #(make-music 'DoublePercentEvent
    'length (ly:make-moment 9/16))

There is a whole bunch wrong with that.  But the graphical output in
_this_ staff (others will likely need to have the time signature made
invisible as well) seems to be more or less what you want.  Maybe one
can play around in order to make the input correspond a bit better with
the logic.
