Playing/viewing MIDI files

node index.js <filename.mid> [<midi-out port> | print | inspect | base64]

e.g.:
node index.js midi/test-c-major-scale.mid
-- play MIDI file to the default MIDI-Out port.
node index.js midi/test-c-major-scale.mid "Microsoft GS Wavetable Synth"
-- play MIDI file to the specified MIDI-Out port.
node index.js midi/test-c-major-scale.mid print
-- print MIDI file contents.
node index.js midi/test-c-major-scale.mid inspect
-- same as print, but also outputs the data offset within the MIDI file.
node index.js midi/test-c-major-scale.mid base64
-- output the MIDI file binary data in Base64 format.

Creating your own test

Copy code/test-c-major-scale.js or your favorite test in the code directory.
Make changes using the API documented at https://jazz-soft.net/doc/JZZ/midifile.html to suit your test case.
Run node code/your-test-name.js, it will create a MIDI file with the same name in the midi directory.

If you believe your test will be useful for others, please check it into this repository!
