I'm having trouble with PD recognizing the virtual ports. I've loaded snd-virmidi and when I do:
$ aconnect -lio client 0: 'System' [type=kernel] 0 'Timer ' 1 'Announce ' Connecting To: 128:0 client 80: 'Virtual Raw MIDI 2-0' [type=kernel] 0 'VirMIDI 2-0 ' client 81: 'Virtual Raw MIDI 2-1' [type=kernel] 0 'VirMIDI 2-1 ' client 82: 'Virtual Raw MIDI 2-2' [type=kernel] 0 'VirMIDI 2-2 ' client 83: 'Virtual Raw MIDI 2-3' [type=kernel] 0 'VirMIDI 2-3 '
Then :
$ aconnect 80:0 82:0
client 0: 'System' [type=kernel] 0 'Timer ' 1 'Announce ' Connecting To: 128:0 client 80: 'Virtual Raw MIDI 2-0' [type=kernel] 0 'VirMIDI 2-0 ' Connecting To: 82:0 client 81: 'Virtual Raw MIDI 2-1' [type=kernel] 0 'VirMIDI 2-1 ' client 82: 'Virtual Raw MIDI 2-2' [type=kernel] 0 'VirMIDI 2-2 ' Connected From: 80:0 client 83: 'Virtual Raw MIDI 2-3' [type=kernel] 0 'VirMIDI 2-3 '
Then:
$ pd -midiindev 23 -midioutdev 21
I get :
couldn't open MIDI input device 22 couldn't open MIDI output device 20 opened 0 MIDI input device(s) and 0 MIDI output device(s). Sample width set to 2 bytes
The only device I can use is mididev 3 ie.
$ pd -mididev 3 doesn't generate "couldn't open ......."
?? ( I don't have a real device attached at this point) . Output of :
$ pd -listdev

API number 1
no midi input devices found no midi output devices found couldn't open MIDI input device 0 couldn't open MIDI output device 0 opened 0 MIDI input device(s) and 0 MIDI output device(s).
Any thoughts on what I'm doing wrong? Jim
Hallo, jim ruxton hat gesagt: // jim ruxton wrote:
I'll take a look at this. Do you mean a " noteout "? Is there a way that I can see the actual midi data going out so I can see what I'm sending? I'm using Linux.
You could use a virtual midi connection using the snd-virmidi virtual card, which works even with only Pd as clients. Example:
$ su -c modprobe snd-virmidi
$ aconnect -lio client 0: 'System' [type=kernel] 0 'Timer ' 1 'Announce ' client 64: 'Rawmidi 0 - M Audio Audiophile 24/96 MPU-401' [type=kernel] 0 'M Audio Audiophile 24/96 MPU-401' client 72: 'Virtual Raw MIDI 1-0' [type=kernel] 0 'VirMIDI 1-0 ' client 73: 'Virtual Raw MIDI 1-1' [type=kernel] 0 'VirMIDI 1-1 ' client 74: 'Virtual Raw MIDI 1-2' [type=kernel] 0 'VirMIDI 1-2 ' client 75: 'Virtual Raw MIDI 1-3' [type=kernel] 0 'VirMIDI 1-3
$ aconnect 72:0 74:0
$ aconnect -lio client 0: 'System' [type=kernel] 0 'Timer ' 1 'Announce ' client 64: 'Rawmidi 0 - M Audio Audiophile 24/96 MPU-401' [type=kernel] 0 'M Audio Audiophile 24/96 MPU-401' client 72: 'Virtual Raw MIDI 1-0' [type=kernel] 0 'VirMIDI 1-0 ' Connecting To: 74:0 client 73: 'Virtual Raw MIDI 1-1' [type=kernel] 0 'VirMIDI 1-1 ' client 74: 'Virtual Raw MIDI 1-2' [type=kernel] 0 'VirMIDI 1-2 ' Connected From: 72:0 client 75: 'Virtual Raw MIDI 1-3' [type=kernel] 0 'VirMIDI 1-3
$ pd -midioutdev 11 -midiindev 13 (using 11 = 'Virtual Raw MIDI 1-0' + 1 and 13 = 'Virtual Raw MIDI 1-2' + 1)
Now open "Test Audio and MIDI" and if you enable "MIDI OUT" you should see the notes coming in at "MIDI IN".
