Hardware midi support through class compliant usb midi device

[JordanSabie]

It would be cool to use a Yamaha mt-32 with this to hear video games' midi soundtrack. More for my purposes it would be cool to use Cubase and output to actual midi devices, something like the m-audio USB UNO if at all possible.
I could even send you one of these if you're interested in looking into it.
Hatari on windows and Linux has this ability. I don't know what would be required to enable this on Wii, but I have seen USB probing apps.
