Bad interaction between MIDI volume and skipTypesetting

[David Kastrup]

Example file:

timetrack =
{
  \set Score.skipTypesetting = ##t
  \skip 1
  \set Score.skipTypesetting = ##f
  \skip 1*2
}

music =
{
  c1\mf
  c1\f
  c1\ff
}


\score {
  << \music
     \context Staff \timetrack
   >>
  \midi { }
}

Output:
