I just did a ten track recording in the latest version of SPlat Newberyport 64 bit and it seems if I use Ozone on my masters or any pro channel effects on any channel I get some weird volume up and downs throught the whole project.
I have a midi channel running Addictive drums and all the other tracks are analog bass, synth, drums, sound effects, keys etc.
Only one track has automated volume set up and what is really weird is if I put a pro channel compressor on the master it doesn't compress the volume just goes up and down as if bielzebub Himself is controlling things .
So where do I start to find what is causing this???
I have i7 2600 cpu  @ 3.4ghz with 16 gig of Ram I have a presonus 16-4-2 digital mixer and Genelec speakers and sub
 
Cheers

Sounds odd. So it's only that one project having this volume variation problem?
The first thing that popped into my mind was possible accidental control automation of the
FX output (or input) levels, but that doesn't sound very likely, after all. Are there any FX involved that create anything random, like an autopanner or something?
Does the issue occur also if you play back only one track/any track at a time? What I would try is playing back the project and muting one track and bypassing one FX at a time, just to try to isolate the cause.

Sounds like you need an exorcist!

I think you nailed it Kalle Rantaaho
I went thru and made sure every fx bin was off and it seems to be at a constant volume now.
So call off the Exorcist for now Paradox Cheers thanks for the clues.
Will investigate further now.
