I want to automate the process of generating a midi metronome track
for rehearsal purposes. It's trivial if the piece is in the same
meter throughout, e.g. if the piece has 97 measures in 4/4 you can
do:
\new Voice = "Click" {
\set midiInstrument = #"woodblock"
\repeat unfold 97 \drums {wbh4 wbl wbl wbl}
}
but what if the meter is frequently changing? I'm transcribing the
baritone part out of a large new work that, no exaggeration, seldom
goes more than a few bars without changing meter. I googled various
combinations "LilyPond", "metronome", "click", & "measure" but didn't
find anything. Is there a scheme function I can use to detect the
start of a measure and the current meter? Or some other way to
accomplish the same thing. I want to end up with a music function
that looks like
\clickTrack \mymusic
that will scan through a music variable, \mymusic, and return a
"wbh" on each downbeat and a "wbl" on the remainder.
Cheers,
Mike
