for harry learn how to use midi by python
安装
pip install MIDIUtil
生成文件
with open("major-scale.mid", "wb") as output_file:
MyMIDI.writeFile(output_file)
解读
通过循环
for i, pitch in enumerate(degrees):
MyMIDI.addNote(track, channel, pitch, time + i, duration, volume)
增加midi内容，要想研究透，就需要把midi文件格式原理搞清楚，才能理解用midi做电音
这里需要注意的是，mido需要backend的支持，单独安装mido没用
pip install mido
pip install python-rtmidi
其中 python-rtmidi 是mido库默认的推荐backend，有了backend，mido库才能起作用
代码都是官方的，都能用
