I suppose this doesn't mention AMT? Can I have this information. It
might contain more than what I already have.

I think both devices act as a single MIDI device where the 0xf5 message
that is undefined in the MIDI spec is used for cable selection. Thus the
running status is for the MIDI stream and not per cable. I don't think
these devices use running status on transmitting (to the host at least)
themselves.

Is it possible to open files from the kernel? I'd suggest having support
for devices like the Unitor in user-space to be able to support them on
any serial port if this is not the case.
