No stock options will be emitted to the responsible developers unless this deficiency is cured before 2.16 gets released. In other words: no, this is not "on the list for 2.16". If you are interested in the release criteria for stable releases, they can be found in the Contributor's Guide in the documentation if memory serves me right. -- David Kastrup ___ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user

Thanks, Hans. I did find that report while searching but I wasn't
sure whether it was the same problem as the report dealt with mapping
dynamic changes to parallel skip sequences. My report deals with
instrument changes in single voice melodies.
I'm not sure how I would go about implementing the suggested
workaround for my application. I run into the problem primarily when
transcribing individual choral parts for my section. It's nice in the
midi output if cues from other parts are sounded by a different
instrument. Since I don't have time to transcribe the entire score,
it's not practical to use the built-in LilyPond cue methods, so I
wrote my own that temporarily changes the instrument, shrinks the
font, and changes the font color, thus:
cueNotes=
#(define-music-function (p l music) (ly:music?)
"for printing cue notes in teeny font in color"
#{
\set midiInstrument = #(cueInstrument 'get)
\override Accidental #'color = #(x11-color 'maroon)
\override Beam #'color = #(x11-color 'maroon)
\override NoteHead #'color = #(x11-color 'maroon)
\override Rest #'color = #(x11-color 'maroon)
\override Slur #'color = #(x11-color 'maroon)
\override Stem #'color = #(x11-color 'maroon)
\override Tie #'color = #(x11-color 'maroon)
\teeny
$music
\normalsize
\revert Accidental #'color
\revert Beam #'color
\revert NoteHead #'color
\revert Rest #'color
\revert Slur #'color
\revert Stem #'color
\revert Tie #'color
\set midiInstrument = #(mainInstrument 'get)
% Note: cueInstrument and mainInstrument are scheme objects with
a "get" method
% that returns a string, e.g "acoustic grand"
#})
and apply it like this:
...
do4 sol mi do |
\cueNotes { do^"Sop. 8va" re mi fa } |
sol mi do2 |
...
How would I go about applying the workaround from the bug report to this?
In any case, this seems to me like a fairly serious defect. I hope
it's on the list for 2.16.

midiInstrument changes play one note too late.
Is this a known problem? I don't see any prior reports online and
I've been seeing it since at least 2.12 but assumed it was because I
was doing some fairly complicated things. I took time to reduce it to
a minimal example today. It's still present in 2.15.33 as shown by the
example below. FWIW, I'm running OS X 10.6.7 and playing the midi
with QuickTime. I'm attaching the midi file.
Is there a workaround?
Thanks,
Mike
%% Minimal Example

\set midiInstrument = "acoustic grand"
