Guess I’ll stiwch to Ardour then. I have tried both Ardour and LMMS in the past, but found Ardour to be too overwhelming. Thank your for writing such an elaborate comment, it really helps!
Also, I was really confused when I realized that the default Gnome installation which comes with Debian 12 is still X11. I thought gnome would have been Wayland only for some years by now. Might also just be the case because I’m using an NVidia GPU… Cuz yeah, Wayland really is just better to use now then X. That’s my experience on my ThinkPad at least. I tried installing the Wayland version, but couldn’t find it “gnome-session-wayland” in apt. I’ll look further into things there.
