Hi all,
I have been working on chord charts which I wanted to use as the input
for
my arranger to generate MIDI backing files, I wanted to use Program
Change
messages to switch the sections of the auto-accompaniment. While trying
to
achieve that I found the following bug:
% somewhere in the included file:
pc_fillB = \set Staff.midiInstrument = #"pad 1 (new age)"
% in the file itself:
intro = \chordmode {
\repeat percent 2 { c1 a:m f \pc_fillB g }
}
In the resulting MIDI file the Program Change message is sent only
once, at
the beginning of the 4th bar. All the 8 bars of notes are generated
properly. Yes, I understand that Lilypond is *not* a MIDI sequencer :-)
Thanks in advance for the time of everyone who cares to look into it.
Did you forget to \unfoldRepeats? The following works fine for me:
%%%%
\version "2.22.0"
\include "articulate.ly"
instrA = \set Staff.midiInstrument = #"acoustic grand"
instrB = \set Staff.midiInstrument = #"flute"
instrC = \set Staff.midiInstrument = #"string ensemble 1"
music = { \repeat percent 2 { \instrA b'4 \instrB 4 \instrC 2 } }
\score { \music \layout { } }
\score { \articulate \unfoldRepeats \music \midi { } }
%%%%
