Re: [pygame] detectng midi events in pygame?

Hi Brian,

The pygame midi.py example has an input event display mode.

python -m pygame.examples.midi -i
It is in the examples subdirectory in the pygame package directory. Unfortunately, the PortMidi with pygame.midi wraps does not have a midi event callback option, so midi events must be polled.

How can I detect midi events in pygame? I am able to detect the count of MIDI devices and input and output device names (see program below) I'd like to display the midi note names like "C3 ON" or "D3 OFF". I am using the JACK Audio Connection Kit. Any code snippets, links to articles, or suggestions would be greatly appreciated.
