Izotope Ozone 5 and -6085 Buffer Underflow

[lowlights]

Just built a new 6-core i7 Win 7 machine and was running it through it's paces (and thanks to the DUC for all the build suggestions as I was picking hardware)

Everything runs a champ (even before doing Win 7 optimizations), but while mixing a 10 track audio session, I wanted to put Ozone 5 on the master buss, just to give my friend a bit of "what mastering/volume" will sound like (he's hiring a real mastering engineer).

Funny thing - any time I clicked a different present - it would throw a -6085 "underflow" error. I used to get this with Ozone 4 on my old machine too - I know Ozone needs some CPU, but this machine is pretty beefy, so I'm surprised I'm spiking.

Is this a thing with Ozone 5 (I installed the very latest version a week ago, so ...) or is some Win 7 optimization just need doing here or ...

Any other thoughts? Would appreciate it.

I only see this if PT is in "Play" while making changes to Ozone. (I seldom use Ozone anymore.)

You're right - when the session is playing back and I attempt to change presets in Ozone, it stops the session and throws the error.

Doesn't throw me OUT of the session, just annoying.

Many plugins allow switching presets and I just hoped to hear the difference from one to the other "in motion" - but Ozone and PT don't love it.

Is it just not do-able? Am I being naive?

I have an HDX card and a hex core CPU, and Ozone changes while playing will sometimes even crash PT, let alone a billion 9xxx errors.. I don't even try anymore. There are other ways to get there.

Thanks Tom - I won't worry about it then - just be more careful when I'm tweaking Ozone.
