Style files

Reading file

var fs = require('fs');
var data = fs.readFileSync('my-style.sty', 'binary');
// data can be String, Buffer, ArrayBuffer, Uint8Array, Int8Array,
// or a JZZ.MIDI.SMF object
var sty = new JZZ.MIDI.STY(data);

Extracting MIDI tracks

console.log('All style tracks:', sty.tracks());
// additional track names not reported by tracks() can be:
// '', 'SFF1', 'SFF2', 'OTSc1', 'OTSc2', 'OTSc3', 'OTSc4' (if present)
var smf = sty.export('Intro A'); // see JZZ.MIDI.SMF
fs.writeFileSync('intro-a.mid', smf.dump(), 'binary');
fs.writeFileSync('otsc1.mid', sty.export('OTSc1').dump(), 'binary');

Cleaning up

// remove the OTSc section: it is not required
// unless you use it on a Yamaha keyboard (see the docs...)
delete sty.otsc;
// remove the FNRc section: it is not used for playback
// and in most cases contains garbage (see the docs...)
delete sty.fnrc;

Writing file

fs.writeFileSync('new-style.sty', sty.dump(), 'binary');
