How do I get MIDI dynamics from a \Dynamics staff?

[Peter Toye]

I want to have a Dynamics staff between the music staves on a PianoStaff, but this doesn't change the dynamics on the MIDI output. Is there any way of getting the MIDI output to use the \Dynamics? In the example below they all have the same (presumably default) dynamic (at least, when played through Nero Showtime).

\version "2.19.52"

\language "english"

\score {
  \new PianoStaff {
    <<
    \new Staff {
      \clef "treble"
      c''4 4 4 4
    }
    \new Dynamics {
     s4\f 4\pp 4\ff 4\mp
    }
    \new Staff {
      \clef "bass"
      c4 4 4 4
    }
    >>
  }
  \midi {}

}
