It appears as if Rosegarden will use "unnamed" if you don't give the
device a name in the device manager. This might be the issue you are
seeing. Try this:
- Launch the Manage MIDI Devices dialog: Studio > Manage MIDI Devices.
- Make sure each device has a name other than "New Device".
- From the command prompt: aconnect -i
- Each device listed here should have a full name. None should be named
"unnamed".
E.g. I created three devices and only gave one of them a name ("Device
with a name"):
- New Device
- New Device
- General MIDI Device
- Device with a name
...and I get:
client 128: 'rosegarden' [type=user,pid=131091]
1 'sync out '
2 'out 1 - General MIDI Device'
3 'out 2 - Device with a name'
4 'out 3 - unnamed '
5 'out 4 - unnamed '
What do you see in your case? What is in Manage MIDI Devices? Are
any "New Device"?
A quick glance at AlsaDriver does not reveal where the actual device
name is added to the port name. I need to do more digging if the above
doesn't help.

The code in question is here:
AlsaDriver::createMidiDevice()
It appears to create all ports with the name "out x - unnamed". What
does a2jmidid show?
a2jmidid shows correct names in a form such as:
'rosegarden [129] (capture): out 1 - General Midi'
Aj2midid does react to deleting and creating a new MIDI out port (i.e.
'device' but if you create one when it has already been started it won't
ever pick up the correct name. On the other hand if you load a
rosegarden file which already contains multiple midi out devices with
different names it will indeed pick them.

Hi all,
So pipewire provides a 'midi bridge' from ALSA MIDI to JACK MIDI out-
of- the-box, which is quite cool for example to connect Rosegarden
to, say, Carla or Ardour.
Problem is that it doesn't seem to pick up the names assigned within
Rosegarden (as a2jmidid seems to, albeit not being able to detect
name changes); all ports are just listed as 'out 1 - unnamed', 'out 2
- unnamed', etc.
I've tested for instance with Pure Data MIDI outs and Qtractor MIDI
'buses' (both also using ALSA MIDI, and the names seem to be picked
up by the pipewire MIDI bridge.
Yet, I'm not 100% if the culprit is Rosegarden or pipewire... Any ideas?
