title: How to save output in music21 as a MIDI file?
body: <p>How do I save audio output in Python using the music21 module? I have read the entire [user's guide](<a href="http://music21.readthedocs.org/en/latest/usersGuide/index.html]" rel="noreferrer">http://music21.readthedocs.org/en/latest/usersGuide/index.html]</a> of said module, but I couldn't find any information about saving output as an audio file that can be recognised by windows without any additional software (MIDI for example).</p>
