X1B - Fast Bounce = Crash. Slow Bounce = OK

I don't know why I'm having all these issues - want to know if anyone else is noticing similar problems.

Whenever I Slow Bounce, all is fine. But every time I want to do any sort of fast bounce, Sonar freezes and ultimately I have to restart my machine. FML.

Whether or not Sonar is to blame here, I'm totally fed up with these constant issues. Lately I've spent much more time troubleshooting than anything else, and I'm out of patience! Does this issue sound like it could be caused by 3rd party plugins?

Sonar X1B, i7 8-Core, 24GB RAM, Kontakt 4, Trilian, Omnisphere, Waves... anything else you need to know?

I'd be OK if my problems were consistent - but they're NOT. Not until X1B have I faced this specific issue. I know that it could be any number of things, but the bottom line is, I just want things to WORK. Upgrading to X1 was a huge mistake, the biggest setback to my productivity in 2011.

Never before has my process been so crippled...  I don't see why, all of a sudden, I cannot fast bounce. Sonar has never been less stable for me than it is now!

Does this issue sound like it could be caused by 3rd party plugins?

 
Absolutely...
Make a test copy of the project... and try pulling out various plugins (one-at-a-time) to find the culprit.

Having the same problems, but I haven't had time to figure out the culprit.

Using UAD-1
Waves CLA
Waves SSL
Waves V-series
Duende Native

I will update to X1b later today and see if that fixes it.  If not, I'll start pulling the plugs 1x1 and see if I can narrow it down.

it shouldn't be, as they pulled the "requires kontakt 4.2.2" as a justification for something else recently...

I have an instrument which has become unstable due to the 4.2.2 upgrade, the developer has confirmed that due to some "low level adjustments", the scripting in this instrument is causing crashes. He also told me to "keep it quiet for now" woopsie!

 
You've got recent updates of Omnisphere (1.5), Kontakt (4.2.2), and Sonar(X1b).
That's a lot of new variables...  

Check the value of BounceBufSizeMsec= in AUD.INI. This allows SONAR to use a different buffer size for bouncing offline than it uses for real-time playback. At the default of 0, SONAR uses your real-time audio buffer size for offline bouncing. If that buffer setting is very small, problems can arise with some plug-ins.
 
I once solved a synth-freezing problem by bumping BounceBufSizeMsec up to 4 when my real-time buffer was 2ms (setting the real-time buffer to 4ms also solved it). Since then, I've been running it at 20. Values up to 200 or so are supposed to be reasonable, but higher values use more RAM during bounce, which can cause problems is your bouncing down a large mix.
 
All that said, Noel Borthwick recently recommended an X1a user change BounceBufSizeMsec back to 0, and it solved the problem. So it seems X1 may be using this value differently than previous versions. But if X1a was okay, a good starting point would be to make sure the X1b's AUD.INI file has the same value as X1a. If they're the same, and not 0, try that in X1b.
 
I bounced down a couple of good-sized projects yesterday when I was shaking down X1b, and had no problems.
 
 

thanks all for the help! Will experiment and see if it helps. I'm so glad to have this forum, because I wouldn't have thought of the BounceBufSize possibility!

great! what is your NVIDIA Driver?

it's funny. All of these problems could be caused by having the LATEST drivers and latest versions of software and plugins. I wonder if installing the latest driver for my video card will solve anything, or just f$%@# things up even more!

Hey Alex, rather than doing a selective start up using shift when loading the project, why not try simple freezing them one at a time and trying to bounce after each freeze.

That should be a lot quicker yes?

Using 64-bit X1b here, no problem with fast or slow bounces.

HOWEVER - to the person using the UAD-1 - you need to use slow bounce when going through any external hardware (Duende, Powercore, UAD-1) or using the External Insert plug-in. Fast bounce works only if the plug-in "lives" in the software.
