usage

Its just a function that takes a binary string.

var midiFileParser = require('midi-file-parser');

var file = require('fs').readFileSync('rachnananov.mid', 'binary')

var midi = midiFileParser(file);

It returns an object with header and track info.

You can use it with browserify and brfs:

var midiFileParser = require('midi-file-parser');

var fs = require('fs')

var file = fs.readFileSync('rachnananov.mid', 'base46')

file = window.atob(file)

var midi = midiFileParser(file);
