Re: Sustain in midi output of Piano Centered Dynamics Template

[Oscar van Eijk]

Trevor,

If you're gonna change the template anyway, maybe it's usefull to add an
\unfoldRepeats to make sure percent- and volta repeats are actually repeated
in midi:

\score {
  \unfoldRepeats {
    \new PianoStaff <<
      \new Staff = "upper" << \upper \dynamics \pedal >>
      \new Staff = "lower" << \lower \dynamics \pedal >>
      \new Dynamics = "pedal" \pedal
    >>
  }
  \midi {
    \context {
      \type "Performer_group"
      \name Dynamics
      \consists "Piano_pedal_performer"
    }
    \context {
      \PianoStaff
      \accepts Dynamics
    }
  }
}

Grtz,
Oscar
