Ozone changes snare in mix

anytime you double compress or limit something, there is a price to pay.


the fix comes from knowledge, and experience, of knowing how much..... when..... and combinations of compression. lots of experimenting.
don't use presets.
use less on the mix to begin with, knowing how you plan to master it.
or, get it right in the mix, and back off on mastering.

the truth is out there. in your mix.

Yeh, Doug, that's actually pretty normal. That's why even those who intend to let someone else master their song will put a limiter on just to hear what it's going to do to the mix. Limiters kill transients - it's just what they do - and you're going to hear that most dramatically on the snare drum. 

I'd suggest trying to raise the threshold a little on Ozone's Maximizer. The cost is less volume but the benefit is better transients and punch. No need to squash any more than the genre requires. Also, try the original "Intelligent" algorithm, which on some material may work better than the newer ones. And experiment with the Character slider, which affects release times and therefore transient preservation.
