1041 For emulating the old MIDI 2.0 device without UMP v1.1 support, pass 0
1061 UMP MIDI client such as "MIDI 2.0 Gadget".
1066 For testing a MIDI input from the gadget to the host (e.g. emulating a
1067 MIDI keyboard), you can send a MIDI stream like the following.
1073 client 20: 'MIDI 2.0 Gadget' [type=kernel,card=1]
1074 0 'MIDI 2.0 '
1075 1 'Group 1 (MIDI 2.0 Gadget I/O)'
1082 client 24: 'MIDI 2.0 Gadget' [type=kernel,card=2]
1083 0 'MIDI 2.0 '
1084 1 'Group 1 (MIDI 2.0 Gadget I/O)'
1097 For testing a MIDI output to the gadget to the host (e.g. emulating a
1098 MIDI synth), it'll be just other way round.
1108 The access to MIDI 1.0 on altset 0 on the host is supported, and it's
1120 where 0 = unused, 1 = MIDI 1.0 (altset 0), 2 = MIDI 2.0 (altset 1).
1121 The example above shows it's running in 2, i.e. MIDI 2.0.
