Re: Creating midi file that is not empty

[Hwaen Ch'uqi]

Greetings Claire,

Puzzling. I just tried your code, and it worked just fine for me. The
terminal output was:

Playing Claire.midi
MIDI file: Claire.midi
Format: 1  Tracks: 2  Divisions: 384
Sequence:
Text: creator:
Text: GNU LilyPond 2.20.0
Track name: \new:
Playing time: ~5 seconds
Notes cut: 0
Notes lost totally: 0

And, indeed, three quarter note C's were played. It makes me wonder if
the issue hasn't something to do with your midi configuration itself?
Just a thought. I am using timidity for midi playback with the
freepats sound fonts.
