| 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) |
| 24 | |
