It looks like you are using a more recent version of linux that has transitioned to using Pipewire (instead of Jack etc.)

Thanks IOhannes :)

so the result of acconnet -l is:

client 0: 'System' [type=kernel]

    0 'Timer           '

Connecting To: 142:0

    1 'Announce        '

Connecting To: 142:0

client 14: 'Midi Through' [type=kernel]

    0 'Midi Through Port-0'

client 20: 'MIDI Mix' [type=kernel,card=1]

    0 'MIDI Mix MIDI 1 '

client 142: 'PipeWire-System' [type=user,pid=895]

    0 'input           '

Connected From: 0:1, 0:0

client 143: 'PipeWire-RT-Event' [type=user,pid=895]

    0 'input    

Which is what worries me cause there is no Pure Data even if it's running....

that's the correct syntax.

Pd has to run (with alsamidi) :-)
what's the output of 'aconnect -l'?

it's also part of the "aconnect" library (where you find [aconnects]).
version 0.5 is available on deken.
the library itself is not "discontinued" in the strict sense. it hasn't
seen much love since 2021, but it is supposed to "just work".
the repository (for feature requests, bug-reports,...) is at
<https://git.iem.at/pd/aconnect>

[aconnect] (like [aconnects]) only gives you the error number (not the
full error).
(which could be a feature-request :-))
