New issue 1648 by [email protected]: MIDI: no defined order between a
simultaneous note-on and note-off
http://code.google.com/p/lilypond/issues/detail?id=1648
\version "2.13.61"
\score{
\new Staff
<< {d'' b'} \\ {b' g'} >>
\layout {}
\midi{}
}
produces a MIDI file with two simultaneous events on the same channel:
the note-off for the first b' and
the note-on for the second b'
Previously, these events were in the same midi-file track, with the
note-off coming first, which seemed to reliably cause the note-off to be
sent to the synthesizer first. In 2.13.61, each voice is now stored in its
own midi-file track, and the upper voice happens to be first.
At least one MIDI player (Windows Media Player) seems to send the note-on
for the upper-voice b' just before the note-off for the lower-voice b',
thus cutting off the upper-voice b'.
Workaround:
\set Score.midiChannelMapping = #'staff
