I'm trying to make 

\score { \unfoldRepeats %\articulate
  <<
    \set Score.midiInstrument = #"electric bass (finger)" % 34
    \new ChoirStaff <<
      \new Staff {
        \set Staff.midiPan = #90
        \context Voice = Vs { \fmks }
      }
      \new Staff {
        \set Staff.midiPan = #30
        \context Voice = Va { \fmka }
      }
      \new Staff {
        \set Staff.midiPan = #-30
        \context Voice = Vt { \fmkt }
      }
      \new Staff {
        \set Staff.midiPan = #-90
        \context Voice = Vb { \fmkb }
      }
    >>
  >>
  \midi { \tempo 4 = 108 }
}

to work.

Getting from .ly file to c++ was easy, but how do I get the
pan-setting down to midi ?

My current try is

 http://turkos.aspodata.se/tmp/pan.diff

and my guess is that somehow
 Staff_performer::acknowledge_audio_element
is run, which adds things to the audio_staff.

Then, somehow something from midi-chunk.cc is run.

Soo, how far off from reality am I?
