Any users encountered this with Sonar 2.2?

I've had Kontakt but a week and am lovin' it, but I have a small issue I'd be interested to know if anyone else has encountered.

I'm running it as a DXi in Sonar 2.2, XP, a gig of RAM and a Layla (6.08) off a dedicated drive. Whilst I keep my latency low all's well but should I take my latency up (say past 500ms) it crashes Sonar. Dropouts in Kontakt occur in the 400-500ms region. If it's a known issue and upgrading to Sonar 3 is the solution, then I'll do that, though I'd like to find a simpler solution if one is in the offing.
Thanks all
David

 

Yep. I was easily able to create the crash by raising the slider to the top (I max out at 350ms). I got the "Sonar.exe has generated errors..." message. Good night.

Just curious: Why would you put your latency that high? I've never had the slider up that far; that's just too much latency to run a mix in realtime! I think the highest I've ever had SONAR's latency at is about 100ms, and that was back in Sound Blaster Live days! You should be able to (with a nice sound card like that) run SONAR at 10 to 40ms, which will make DXi's run much more smoothly. Unless you have a slow computer, I strongly recommend putting SONAR back down to a smaller latency.

Best Regards,

 

Sonar does live for the most part round an effective 8.8ms with no problems. I became aware of this issuse when remixing some older (pre DXi) tracks with very large numbers of Waves plugs and needed to up the slider to stop the engine from stopping. When then loading a Kontakt project with the slider in the former position, she tipped over and I figured she should'na have. I'm new to DXi's, be gentle with me!
Anyway thanks for checking it out and getting back. I now know it's not a setup issue of mine.
Cheers

Yeah, no setup issue. You have to keep latency as low as possible to run most DXi's effectively. Even in Cubase with ASIO drivers: if I go much above 80ms, VSTi's start sputtering and become unstable. SONAR just decides to give up entirely. You probably want to bounce down some of those Waves-tracks to reclaim CPU.

Good luck,

 

Yes, there was a bug in our DXi code that crash our applications when the buffersize was bigger then 8192 samples (185 ms at 44100 kHz). This is fixed in Kontakt 1.5 (and all other releases that are younger then two or three month). Sorry for the circumstances, this bug was my fault

Bye,

Thanks for adding that, Stephen.

 

And from me, though I'd let the tech-help folk know so their blaming of the host (as they did) doesn't make them look daft.
