Hi, folks.

Dear Matt, another user, with the same MIDI Controller contact me in
private last month. He got it working, then I compiled the experience
in a thread (FreeBSD Forums)  : , if you are interested.
Hope it is accurate, I tried to explain how this works in FreeBSD, and
pointed how to do it; suggesting some MIDI apps to play.
