8 MIDI 2.0 is an extended protocol for providing higher resolutions and
9 more fine controls over the legacy MIDI 1.0. The fundamental changes
10 introduced for supporting MIDI 2.0 are:
12 - Support of Universal MIDI Packet (UMP)
13 - Support of MIDI 2.0 protocol messages
14 - Transparent conversions between UMP and legacy MIDI 1.0 byte stream
15 - MIDI-CI for property and profile configurations
17 UMP is a new container format to hold all MIDI protocol 1.0 and MIDI
21 16 MIDI channels.

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)
