I think there was an insightful email in the mailing lists a couple of
years ago that explained that the current solution of handling MIDI
tempo changes will only work with certain MIDI players but not
with all. I just tried to listen to your example using kmidi (which
internally uses timidity, a software-only MIDI interpreter) and it
certainly plays the correct tempo changes, but it may fail for your
combination of sound card and software.

Hello
according to the mail archives, I should just insert a \tempo directive
whenever I want to change the tempo (I think this should be in the
manual).
1) For multiple staff music, should I insert just one
set of markings for one of the staves (does it matter
which one) or should they all have a (redundant)
tempo marking ?
2) Regardless, this does not seem to function. Here is a little bit
of test music.
sopNotes = {
\relative c' {
\tempo 4=100
e2 e2 e2 e2 e2 e2 e2 e2
\tempo 4=50
e2 e2 e2 e2 e2 e2 e2 e2
}
}
%
mezNotes = {
\relative c' {
\tempo 4=100
c2 c2 c2 c2 c2 c2 c2 c2
\tempo 4=50
c2 c2 c2 c2 c2 c2 c2 c2
}
}
\score {
\new ChoirStaff
<<
\new Staff { \context Voice = sop { \sopNotes } }
%
\new Staff { \context Voice = mez { \mezNotes } }
%
\layout {}
\midi {}
}
The resultant midi file (attached) does not change tempo. It makes no
difference whether I use one staff or two (and also if I
use one staff and drop the \new ChoirStaff syntax it also
does not work).
I am using V 2.6.3-1 on a Mac Powerbook
