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
%% BUG? Midi instrument changes are delayed by one note.
mymusic = {
\set midiInstrument = "acoustic grand"
c'1^"pno." | % midi ok
\set midiInstrument = "cello"
d'1^"cel." | % wrong : midi plays piano.
\set midiInstrument = "acoustic grand"
e'1^"pno." | % wrong : midi plays cello
c'1^"pno." | % midi ok
}
\score {
\new Voice = "Test" { \mymusic }
\layout {}
\midi {
% This lets us specify instrument in melody
\context {
\Staff
\remove "Staff_performer"
}
\context {
\Voice
\consists "Staff_performer"
}
}
}
\version "2.15.33"
Cheers,
Mike
