I've been working with the new Ozone 6 over the last couple of days and discovered a great workflow. In standalone mode Ozone 6 allows a VST plugin to be inserted into its matrix. I've been inserting T-RackS Custom Shop into that slot and it allows me to set up an additional chain with it
 
It's very flexible. I only wish the standalone GUI of Ozone was resizable as it's pretty small.

In todays age, with multimonitors and large screens, dinky UI's are inexcusable... Just don't get it! And this is their NEW version!  Well, thanks... that's one mastering plug I don't have to audition before making my choice!

southpaw - inserting a chain into that module slot in Ozone 6 is a great idea.  Hadn't thought of that, but totally makes sense.
 
I didn't go for Ozone 6 when the upgrade price was reasonable but if I had thought of that it might have gotten me over the decision hump.
 
 

Southpaw.... while demoing all the mastering tools I've found I too am liking Ozone's insert abilities... I'm going FabFilter's mastering bundle and find inserting their Pro-MB and Q2 really awesome...
 
Unfortunately, can't afford both... so gonna get Fab now and iZo down the road...
