8 title: Generic Serial MIDI Interface
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
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),
23 results in the standard MIDI baud rate, and set the 'current-speed' property to 38400 (default)
30 const: serial-midi
