[resolved] MIDI keyboard with pipewire

Hi,
I bought a MIDI in/out to USB cable to use with my old keyboard.
When plugging it in I see the following in the logs:

May 30 17:02:38 arch-desktop kernel: usb 1-3: new full-speed USB device number 4 using xhci_hcd
May 30 17:02:38 arch-desktop kernel: usb 1-3: New USB device found, idVendor=fc02, idProduct=0101, bcdDevice= 2.50
May 30 17:02:38 arch-desktop kernel: usb 1-3: New USB device strings: Mfr=0, Product=2, SerialNumber=0
May 30 17:02:38 arch-desktop kernel: usb 1-3: Product: USB MIDI Interface

May 30 17:02:38 arch-desktop systemd[1365]: Reached target Sound Card.
May 30 17:02:38 arch-desktop mtp-probe[28142]: checking bus 1, device 4: "/sys/devices/pci0000:00/0000:00:01.3/0000:01:00.0/usb1/1-3"
May 30 17:02:38 arch-desktop mtp-probe[28142]: bus: 1, device: 4 was not an MTP device

But when I try to play notes in Reaper (my DAW) nothing happens.
Using aseqdump and arecordmidi does not seem to work either.

This is what my qjackctl graph looks like:

I don't know how to debug this further and I'm happy about any suggestions.

Linux: 6.9.2-arch1-1
Pipewire: 1.0.7
Reaper: 7.16

Re: [resolved] MIDI keyboard with pipewire

Alright I figured this out. Turns out my midi to USB cable is incorrectly printed. When plugging it in the wrong way it starts working.
