实时获取MIDI设备的输入(Python) [英] Getting input from MIDI devices live (Python)

问题描述

我有一个触发手指(MIDI数位板)，我希望能够实时读取其输入并根据所按的键使python执行动作.

我在Windows上需要它，最好使用python 2.5 +

谢谢

解决方案

PyGame 包含内置的<一个href ="http://www.pygame.org/docs/ref/midi.html" rel ="noreferrer"> midi模块，适用于Linux，Windows和MacOS，并且得到了很好的支持.

例如，这是 pygame.midi的文档.输入:

  Input is used to get midi input from midi devices.
  Input(device_id)
  Input(device_id, buffer_size)
        Input.close - closes a midi stream, flushing any pending buffers.   closes a midi stream, flushing any pending buffers.
        Input.poll - returns true if there's data, or false if not. returns true if there's data, or false if not.
        Input.read - reads num_events midi events from the buffer.  reads num_events midi events from the buffer.

如果您正在寻找替代方法，请查看Python Wiki中的 PythonInMusic

有许多与MIDI输入和输出有关的项目，其中一些也适用于Windows. (在每个项目之后单击小号>标记，以访问指向项目主页的链接)

我还没有亲自使用它们，但是我相信它会帮助您入门.

I've got a trigger finger (MIDI tablet) and I want to be able to read its input live and make python execute actions depending on the pressed key.

I need it for Windows, and preferably working with python 2.5 +

Thanks

解决方案

PyGame includes a built-in midi module, available for Linux, Windows and MacOS and is very well supported.

For example, here is the documentation for pygame.midi.Input:

  Input is used to get midi input from midi devices.
  Input(device_id)
  Input(device_id, buffer_size)
        Input.close - closes a midi stream, flushing any pending buffers.   closes a midi stream, flushing any pending buffers.
        Input.poll - returns true if there's data, or false if not. returns true if there's data, or false if not.
        Input.read - reads num_events midi events from the buffer.  reads num_events midi events from the buffer.

If you're looking for an alternative, have a look at PythonInMusic in the Python wiki.

There are various different projects related to MIDI input and output there, some for Windows as well. (Click the little > sign after each project to follow the link to the project homepage)

I have not used any of them personally, but I'm sure it will help you get started.
