you'll want to use the \transposition command

Excuse me, one small questions.
How can I transpose just the midi output?
for example, French horn is in F; we want it sounds fifth lower than
written.
Here are the examples,
0 %% file horn.ly
1 horn = {
2 \set Staff.instrumentName = \markup { \column { "Horn " \line { "in
F" } } }
3 \set Staff.midiInstrument = "french horn"
4 \clef treble
5 \key c \major
6 \time 4/4
7 c' 1 \ppp
8 \bar "|."
9 }
00 %% file music.ly
01 \version "2.10.5"
02 \include "horn.ly"
03 \header { }
04 \score {
05 \horn
06 \layout { }
07 \midi{
08 \context {
09 \Voice
10 \remove "Dynamic_performer"
11 \remove "Span_dynamic_performer"
12 }
13 }
14 }
# so we can run
# lilypond music.ly
Now, the printed music is good, but the midi is not "in tune."
It's in "concert" pitch C, but I want it written pitch C as in F horn,
that
is concert pitch "F."
... sure we can transpose the horn (for example to the fwllowing file),
make
a whoe set of scores, re-run the lilypond for the midi.
0 %% file horn.ly
1 horn = \transpose f c {
2 \set Staff.instrumentName = \markup { \column { "Horn " \line { "in
F" } } }
3 \set Staff.midiInstrument = "french horn"
4 \clef treble
5 \key c \major
6 \time 4/4
7 c' 1 \ppp
8 \bar "|."
9 }
00 %% file music_for_horn_in_F_midi.ly
01 \version "2.10.5"
02 \include "horn_for_midi.ly"
03 \header {}
04 \score {
05 \horn
06 \layout { }
07 \midi{
08 \context {
09 \Voice
10 \remove "Dynamic_performer"
11 \remove "Span_dynamic_performer"
12 }
13 }
14 }
# so we can run
# lilypond music_for_horn_in_F_midi.ly
But, is there a simler way? perhaps like ...
\midi {
\transpose f c \horn
}
%% or
\midi {
\context {
\transpose f c \horn
}
}
%% or
\midi {
\context {
\voice {
\transpose f c \horn
}
}
}
Thank you very much.
and
Nappy New Year
