Are you able to hook into ALSA? I've had reasonable success driving a
USB-MIDI cable using ALSA. See if you can do it with the inbuilt
'pmidi' app first:

$ pmidi -p 128:0 No.19.mid

(that uses port 128:0 which is a TiMidity-provided one)

If that works, you can then look for Python ALSA bindings, which I
believe are available on PyPI.

My example is from Linux, so you may need to tweak things on other OSes.
