This is very odd. All instruments are printed as expected. In MIDI,
though, some instruments are dropped (as in, no MIDI player
acknowledges its existence)...but this happens in only one movement!
Let's go through the process. This is what the trouble movement
outline looks like (two instruments are commented out because I
haven't written them, so they are not included):
\score {
\simultaneous {
\new StaffGroup <<
\new Staff <<
\set Staff.instrument = \markup { "Flauti" }
\set Staff.instr = \markup { Fl. }
\set Staff.midiInstrument = #"flute"
\parameters
\barlinesthree
\spacingthree
\new Voice { \Flutethree }
>>
\new Staff <<
\set Staff.instrument = \markup { "Oboi" }
\set Staff.instr = \markup { Ob. }
\set Staff.midiInstrument = #"oboe"
\barlinesthree
\partcombine
\relative g'' { \OboeOnethree }
\relative b' { \OboeTwothree }

\new Staff <<
\set Staff.instrument = \markup { "Fagotti" }

When compiled in lily .29 OS X binary, every instrument appears in
print: flute, oboe, bassoon, horn, trumpet, timpani, violin 1/2,
viola, cello/bass. When played in timidity, though, it's clear oboe
and timpani are not playing. Indeed, timidity does not even recognise
them:

It's confirmed by opening the .mid in Sibelius...timpani and oboe are
not there.
Next I tried rebuilding the code in the fink-built lily .23. And...the
instruments are back again.

Therefore there is some problem -- I'm guessing -- in .23 < x < .29
that is causing instruments to be excluded from the MIDI.
