rawmidifile

rawmdifile allows you to read and write MIDI files and get at the raw MIDI bytes.

Note: The API is experimental and may change.

>>> import pprint
>>> from rawmidifile import read_rawmidifile
>>> pprint.pprint(read_rawmidifile('example.mid'))
{'format': 1,
 'resolution': 480,
 'tracks': [[(0, b'\xff\x03Melody'),
             (0, b'\xc0\x0c'),
             (16, b'\x90@d'),
             (16, b'\x80@d'),
             (16, b'\x90Gd'),
             (16, b'\x80Gd'),
             (16, b'\x90@d'),
             (16, b'\x80@d'),
             (16, b'\x90@d'),
             (16, b'\x80@d'),
             (0, b'\xff/')]]}

• read_rawmidifile() takes a filename or a file object and returns a dictionary with format (1 or 2), resolution (ticks per beat) and tracks (a list of tracks where each track is a list of (delta, msg) tuples.)
• write_rawmidifile() takes a filename or file object and optional format, resolution and tracks.
• is_meta() checks if a messages is a meta message. (The first byte is 0xff and there is more than one byte.)

Included example:

• mido_midifile.py - an alternative MIDI file reader/writer for Mido built on top of rawmidifile. https://github.com/mido/mido/
