Hi, thanks! You need a device that exposes two separate midi ports in ALSA and apparently a post 5.11 kernel as ALSA changed the way they name the ports in that case. The only device that I know of that exposes two ports is my M-Audio Keystation 88 MK3. I'm on 22.04 so I can only test on that one. Since it's a simple change I guess it would be OK in all other releases as well.
