357 Function-specific configfs interface
358 ------------------------------------
360 The function name to use when creating the function directory is "midi".
361 The MIDI function provides these attributes in its function directory:
364 buflen MIDI buffer length
365 id ID string for the USB MIDI adapter
366 in_ports number of MIDI input ports
367 index index value for the USB MIDI adapter
368 out_ports number of MIDI output ports

430 $ aplaymidi -p 128:0 file.mid
432 MIDI ports can be logically connected using the aconnect utility, e.g.::
436 After the gadget's MIDI port is connected to timidity's MIDI port,
437 whatever is played at the gadget side with aplaymidi -l is audible

999 protocol Default MIDI protocol (either 1 or 2)

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.
1071 $ aconnect -o
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)'
1076 $ aplaymidi -p 20:1 to_host.mid
1080 $ aconnect -i
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)'
1085 $ arecordmidi -p 24:1 from_gadget.mid
1087 If you have a UMP-capable application, you can use the UMP port to
1091 $ aseqdump -u 2 -p 24:1
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.
1102 $ arecordmidi -p 20:1 from_host.mid
1106 $ aplaymidi -p 24:1 to_gadget.mid
1108 The access to MIDI 1.0 on altset 0 on the host is supported, and it's
1115 $ amixer -c1 contents
1117 ; type=INTEGER,access=r--v----,values=1,min=0,max=2,step=0
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.
