Hello, I am running Ubuntu Feisty and have found that raw midi support is missing on my computer. Some games and programs give me this error:

ALSA lib rawmidi_hw.c:233snd_rawmidi_hw_open) open /dev/snd/midiC0D0 failed: No such file or directory

Indeed, that file is missing. I searched all night for an answer, but found nothing. Some people have the file, and some people don't. For the people who don't, there have been at least 30 help threads posted across the internet. Not a single one found a solution. Isn't there anyone in the world who can tell me how to enable raw midi support?
