There are a lot of presets in Ozone - and in 5, when I got the first copy, using those could really alter the sound. It was educational to see what was going on "behind the curtain" but I always treated those like the presets in multi-FX guitar pedal, i.e., a "proof of concept" kind exhibitionism, and not something you'd likely use in real life.
Anyway, that's why I call what I do "pseudo-mastering" - it's all fake

. And, there's never a concept of making a bunch of independent tracks sound consistent, i.e., for an "album" - I know my limits!
I use Ozone pretty exclusively for getting the limiting where it delivers the LUFS target consistently. When they add in the compressor (not always), if it's a bunch, then I almost always go back to my mix and see whether I can make the change in my mixbus compressor (Logic's ITB "Red" emulation), or maybe something else to tinker with. Any kind of compression and limiting is going to change the EQ, and like I said, I'm generally skeptical of any EQ they apply, but if it still sounds good and compares to a reference curve, I don't get too excited about it. (I still don't understand the low shelf boost they stick on there, though, when often there simply isn't any bass content in the mix, e.g., for just a guitar/vocal mix. They could integrate the custom Tonal Balance into that bit of AI and probably do a "smarter" job there. Maybe some future version.)
