13 description:
14 Generic MIDI interface using a serial device. This denotes that a serial device is
15 dedicated to MIDI communication, either to an external MIDI device through a DIN5
16 or other connector, or to a known hardwired MIDI controller. This device must be a
17 child node of a serial node.
18
19 Can only be set to use standard baud rates corresponding to supported rates of the
20 parent serial device. If the standard MIDI baud of 31.25 kBaud is needed
21 (as would be the case if interfacing with arbitrary external MIDI devices),
22 configure the clocks of the parent serial device so that a requested baud of 38.4 kBaud
23 results in the standard MIDI baud rate, and set the 'current-speed' property to 38400 (default)
