用Python读取MIDI文件

Question

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.

Answer 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).

Answer 2

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

Answer 3

有一个名为mido的库，适合阅读这些文件： https ：//pypi.python.org/pypi/mido/1.1.11

Answer 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.

Answer 5

您最好的选择可能是获取ac或c ++库，并使用Python Extensions for c进行交互。
