usb midi devices

[Christian Schüler]

Hi list,
I'd like to know what support FreeBSD has for class-compatible midi 
keyboards in the usb driver. I read something about 'umidi' device but 
it doesn't seem to work. For instance, can I run programs like 
Rosegarden and they will detect the keyboard as midi-input device? For 
not to confuse the meaning of keyboard here, I'm talking about things 
like this:
