如何将magenta.js音符序列转换为midi文件？

npm install @magenta/music

const { midi } = require('@magenta/music');

const noteSequence = {
  ticksPerQuarter: 220,
  totalTime: 1.0,
  timeSignatures: [
    {
      time: 0,
      numerator: 4,
      denominator: 4,
    },
  ],
  tempos: [
    {
      time: 0,
      qpm: 120,
    },
  ],
  notes: [
    {
      pitch: 60,
      startTime: 0,
      endTime: 0.5,
    },
    {
      pitch: 62,
      startTime: 0.5,
      endTime: 1.0,
    },
  ],
};

const midiData = midi.sequenceProtoToMidi(noteSequence);

const fs = require('fs');

fs.writeFileSync('output.mid', new Buffer.from(midiData, 'binary'), 'binary');
