[LAU] Rosegarden which Distro?

Hello all, First post so obviously a newbie question. And this, I know, is a question without answer, as it's a bit subjective. So what is the most convinient distro to get started on. I've previosuly been using an Ubuntu distro which worked up to a point, that point being 'rosegarden'. I really wanted to play with rosegarden so I could enter musical notation and list to the results. That was a step too far for me. I could get qsynth installed and get it making a noise by connecting the qjack keyboard to it in qjackctl, but rosegarden would never play a note. Just could not get it connected up and happy. QJackCtl is fairly straight forward if you have things to interconnect. If there's nothing to connect to when you start up rosegarden you're kinda not going anywhere. So that was Ubuntu, but this laptop, which I've just returned to is running OpenSUSE Leap 15.1, which don't have, or doesn't appear to have, a low latency kernel option. That might mean a return to OpenSUSE Tumbleweed, or other. In most cases Ubuntu would be the easy way to start but I've already been down that road and rosegarden just never showed up in QJackCtl. I should say that the specific multi media distros seem to have fallen a bit behind so they don't look like an option. So perhaps later in the week Tumbleweed with GNOME and try to get a note, just a single note.
