Comment #3 on issue 1647 by [email protected]: MIDI skips note if the
pitch is already sounding in the same channel
http://code.google.com/p/lilypond/issues/detail?id=1647
This issue involves a small section of code, but recent history makes it a
little complicated.
The examples given above sound 'fixed' with the new use of separate tracks
for each Voice. This separates the data streams in such a way that
Midi_walker::do_start_note() analyzes just one Voice at a time, so this bit
of code can no longer see the already-sounding note.
To reproduce this issue in version 2.13.61, we need to set an option that
puts all voices in the same midi-file track:
\version "2.13.61"
\score{
\new Staff {
\set Score.midiChannelMapping = #'staff %%% NEW, relative to original
example
<< {r8 g'4} \\ {g'4 r8} >>
}
\layout {}
\midi{}
}
