I just upgraded from Cubase Pro 10.5 to Cubase Pro 11! Wow! Incredible. One question. Do I need to install Halion Sonic 3/SE if I have Halion 6? I want to free up disk space.
It´s as simple as asking yourself if you ´re gonna need it or not… 
You might already have it installed from an older cubase version, then the update might make sense.
The most disk space can be saved by removing included content you don’t use, but that can be some work that find out.
Thanks! Does Halion 6 have everything Halion Sonic has?
