MIDI files can include events ("key-change meta messages") for key
signatures, each specifying a root and whether it's major or minor (which
actually makes them more expressive than standard notation which can't
distinguish, for instance, between C major and A minor). Lilypond
generates these events in the MIDI files on each key change in my
installation. If Giles's installation appears not to, I wonder whether
that may be due to an issue with the software he's using to examine the
MIDI files.
For instance, this input produces a MIDI file with key-change events at
the indicated places:
\score {
\new Voice {
\key c \major
c'4 d'4 e'4 f'4 |
\key d \minor
bes4 a4 g4 f4 |
}
\layout { }
\midi { }
}
