问题
I want to be able to read events from a MIDI file in Python. I have looked for libraries, but can't find one that works with my MIDI file in windows. I do not need to do anything real time, and just want a simple library that gives me events and times. Would it be easier to write one for myself? Any help would be appreciated.
回答1:
the structure of a midi file is quite simple. if you can't find a ready-made library (i am not aware of any) and you only need events and time, i suggest you try parsing the file yourself.
(prepare for a lot of bit shifting: MIDI data are stored in strings of 7 bits blocks)
also, you say that you can't find a library which works with your MIDI file on Windows: MIDI file are supposed to be portable, and python too, so a un*x lib should work equally well on windows (or the developper missed the point of both MIDI and python).

Check out this python library on github, it seems to do exactly what you need:

回答3:
There is a library called mido which is good for reading these files: https://pypi.python.org/pypi/mido/1.1.11
回答4:
I once wrote a simple library in pure C to read/write Midifiles. If you want to have a look here it is: http://code.google.com/p/middl/
It is a low level library that ease the task of dealing with midifiles but you should be familiar with the Midi file formaat to use it.

Your best bet might be to get a c or c++ library, and interact with it using the Python Extensions for c.
