Hi John, yes I have ASIO selected in my preferences. I'm using an M Audio Audiophile 192 sound card. Could it be that I have an incorrect setting elsewhere in my Sonar preferences? Let me know if you need more info. Thanks

Make sure that no other sound card or audio device is also selected in preferences. Be sure that your project is set to the same sample rate as your card. Then goto the control panel of the Audiophile 192 and set the buffer to 512 if that gives you the best performance.

I would also check your DPC latency. You can do a search for DPC latency checker. DL it and see where you stand. 

 

Thanks John.

I posted about the PC EQ about a year ago. About 80% of the time when I sweep the EQ my project will stop...as if you hit the space bar. It starts back up just fine...but very seldom will it let me sweep any freq in the EQ. Actually, it's not only sweeping the EQ, but adjusting ANYTHING that has to do with the PC EQ.

I was able to run Sonar X1 a few years back, Pro Channel didn't glitch on that system, some drum software was a little intense, when the synth was opened, on that computer, so I would shut down sonar goto the M audio and tweak between 384 samples or 512, this was a Eco dual core that I purchased during a rough patch, same card Audiophile 2496

Then when I purchased a 64 bit win 7 for my Sonar, I installed my trusty Audiophile card, all seemed okay at first, but once I went through the process of installing all my softsynths, I was disappointed that I had to resort to 512 or higher for glitch free playback.....

Of course I tried DPC latency checker, it indicated that my new system had resources that resulted spiking as indicated by that software .....But What?

So yeah I tried suggestions of win 7 tweaks recommended from various sites....no cure

One day I decided to go to system configuration and turned off all services then reboot....my computer looked like win XP Sonar launched and I was able to crank down the ASIO to 64 samples and the new system worked like a charm

Downside....no I tunes....internet.....media player,,,,yikes,,,,,so I started guessing what services I would need but didn't make much headway.... I turned all the services back on a presto Sonar was able to work fine on 64 samples

What I learned from this forum is most members have different issues with their system, there is not a common denominator to disappointing performance

This problem has returned - as predicted. It is really devaluing Sonar X2.
