I found a surprising simple way to play a midi file as input to Csound, via the mido Python library.

Here's the code:

from mido import MidiFile, open_output

port = open_output('NewPort', virtual=True)
mid = MidiFile('midis/moonlight_sonata.mid')

for message in mid.play():
   print(message)
   port.send(message)

The only thing is, the port must be open before you start Csound, but that is not really a problem, because you can start Csound from python after open_output.
A nice application could be in a GUI to show a list of midifiles and another list of csd's to be played by them.

That's neat.

I tried to do that to..mido/midi to OSC. But I got stuck at running status, or in other words: converting midi chords to OSC.
It seemed that OSC could not handle this very well (multiple messages coming in at the same time). That is why I fell back to a pure midi solution..
Did you solve this, and if so I am curious how?

I am using Mido to host Midi...then routing to various csound instruments over OSC.  Makes a nice midi host.
