I have moved this to alsa-devel as it seems more relevant to discuss there.

But it will be a driver module right?

I don't think it will be included in the kernel until it is sufficiently
tested and then if there is a bug it will be found much quicker.

Good point but then if then we shouldn't have included ALSA if that is
true. The ALSA code base is large and having the usb midi module as a
userland app seems to me to go against the precendant set by the rest of
the modules.
