It doesn't arrive in time.

Oh, yes, that's much simpler.

...however, while documenting it, I noticed a problem that makes the
feature nearly useless: the speed of MIDI time depends on the tempo,
which isn't set until the beginning of the score, so the extra time is
at some other tempo (probably 4 = 120). It might still be useful to
align multiple tracks generated by Lilypond (but why not generate them
as one file?) or as input to other programs that want time in MIDI
ticks rather than seconds, but it's not much good for aligning the
MIDI to either musical or real time.
