From the testing I did, the main culprit for the latency I was experiencing with my USB interface and my MIDI controller was the fact that my Pipewire profile wasn't set as `pro audio` (which can be set in PulseAudio Volume Control software in the `Configuration` tab for your USB audio interface). However as its a full profile, it must be one of the specific setting inside that fixes the issue, but I don't know which one. I might need to look into Wireplumber settings (the session manager I use for Pipewire instead of the default one `pipewire-sessions-manager`)

On another note, I found out that my focusrite was held back by factory defaults (3rd gen) and needed to follow a procedure to unlock higher samplerate. Now I am using 1024/192000 Hz and I reach 5.3ms latency without XRuns. (although when the pro audio profile isn't set Ardour would still say that the latency is 5.3 however you can clearly hear its not the case).
