Specify MIDI controller number with Pipewire/Jack

[stefanadelbert]

I'm on Manjaro running pipewire with the Jack shim. I have a USB MIDI controller connected. I'm trying to map the "stop" button on the controller to loopers.

The MIDI device is the "Minilab3 MIDI", shown below

❯ aseqdump -l
 Port    Client name                      Port name
  0:0    System                           Timer
  0:1    System                           Announce
 14:0    Midi Through                     Midi Through Port-0
 24:0    Minilab3                         Minilab3 MIDI
 24:1    Minilab3                         Minilab3 DIN THRU
 24:2    Minilab3                         Minilab3 MCU/HUI
 24:3    Minilab3                         Minilab3 ALV

❯ aseqdump -p 24:0
Waiting for data. Press Ctrl+C to end.
Source  Event                  Ch  Data
  0:1   Port subscribed            143:0 -> 129:0
 24:0   Note on                 9, note 48, velocity 93
 24:0   Note off                9, note 48, velocity 0

I can confirm that the MIDI message on channel 10 note 48 in Ardour MIDI Tracer and midisnooper.

This is how I have loopers configured,

Channel	Controller	Data	Command	Arg1	Arg2	Arg3
*	24	48	Stop	Selected

I am also explicitly connecting the MIDI ins and outs in qjackctl.

But I'm seeing no effect in loopers. I suspect I have the controller set incorrectly in the loopers config.

Please help.
