Andres,

It would be wonderful if you could redo the alsa MIDI module, especially for 
the XO.

It would be just terrific if this could be included in a new Csound XO 
distribution made available as an XO update download.

This would constitute a real contribution toward collaborative music-making 
OLPC style. (It would be immediately applicable to the projects I'm working 
on for XO.)

Hi,

I implemented it (not exactly but made it possible to listen to all
MIDI devices) only for PortMIDI, and the PortMIDI module is not
included in the XO version of csound, only the alsa MIDI module is
available. The alsa sources contain some helpful information. I'll see
if I can cook something.

Cheers,
Andrés
