Fw: Sustain in midi output of Piano Centered Dynamics Template

[Trevor Daniels]

Valentin

Graham fixed most of the problems with the centered piano dynamics template 
recently, but missed this request.  Can I just add this in git or should I 
use lsr update?

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
