Great!

Awesome :)

But aren't the LEDs dependent on the hardware switches?

Yes. I think i can hack something that emulates a MIDI interface,
using ALSA or JACK.

Yes, that's what I had in mind :)

So, I assume this one is not standard... well, otherwise it'd be using
usb-audio instead, no?

Great :)

Thanks a lot for your very detailed answer!
