I use this on the rare occasions when I can't throw a rough master together. Sure, I favor some of it's modules (especially the widener module), but I wouldn't call it fantastic.
A kind of idiot proof mastering tools. I have had Ozone 4,5,6 and now 7. Never the Advanced versions but I doubt I would know what to do with the advanced the Standard works for me!
At the moment I use the free version of LANDR, but at some point I would like to use Ozone on my master to have a bit more control over what I do. However that isn't a priority and I only want to master my own tracks when I properly and completely understand what I am doing.
