Well, here is what works for me (":speed nil" is necessary to trick
make-serial-process into not trying to set a speed on the "serial" port)
for letting Emacs display data arriving on the Midi interface.  On
GNU/Linux.  But it is not unlikely that a character device like that
would be available under OS/X as well.

(make-serial-process :port "/dev/midi1" :speed nil
      :buffer "*lily-midi*"
      :coding 'binary
      :noquery t
      :filter (lambda (process string)
         (message (mapconcat (lambda(x) (format "%02x" x)) string " "))))
