Can I still run Cubase 4 if I upgrade to 10.5

I’m running Elements 9.5 on Mac and was thinking of upgrading to Artist 10.5, but not sure if it will run on El Capitan (don’t want to install Catalina as some of my plugins will stop working).

Presumably, I’ll be able to run Artist 9.5 (or even Artist 10, as I already have 10 LE installed)?
