Ok this is annoying! Some of you may have noticed in another recent post that I mentioned I avoid my Pro Channel because its CPU intensive. I was then shocked by how many people have absolutely no issues with theirs - so why is mine so bad?? I have a powerful PC - 64 bit, Windows 7. I believe the issue is on the EQ only. When I sweep frequencies, play back glitches and 'motorboats' for a second or two and then commences. I literally can't use the EQ because of it. I am not running the signal through any other plug ins, no busses, nothing on the master. It's driving me crazy because the Pro Channel is one of the biggest reasons I upgraded to Sonar X2. Sonitus EQ works absolutely fine. Does anyone have any ideas? Please let me know if you need more information. Many thanks, Dave

Do you have X2a?

(44,100 and 384 sample rate on soundcard)

So which rate are you using?

If it's 384KHz, what happens if you drop your sample rate to something more, er, practical?

yes i have the update. 
sorry, BJ, sample rate is 44100 and buffer size is 384. 

Hi sorry to read this.....Pro channel is awesome for me and i think is bad Sonar install.Try to eliminate AUD.ini and reinstall only Sonar install files and update to X2a.Good luck!

have you tried playing with your buffers ?
its got to be soundcard related.
ive never even heard of such a thing with the pro channel.(not to say this is all in your head,i know its not)
but this is something to do with your sample rate or buffers in que.
or something with the m audio card.

Hi guys thanks for taking the time to help me out. GIM - Re-installing would be a nightmare for me as I am a real amateur when it comes to removing and re-installing large programs like Sonar. I feel out of my depth. Plus, Rain Computers built my PC for me and installed Sonar themselves meaning I'm not familiar with the process. Could you explain to me what 'AUD.ini' is? Also the process of uninstalling and re-installing? How does it effect my license etc (it's a download only version). Rain split my drives into a main and an Audio drive and installed various parts of Sonar into different areas - I'd have no idea how to do that. Sorry for the furious amount of questions but this really makes me nervous. Chucklebaby - I would very much like to exhaust your soundcard theory before re-installing. I have the latest M Audio drivers, a decent sample rate...what else could it be do you think? Many thanks again, Dave

Ok - this is odd. I changed my soundcard buffer size to 512 samples. Then I booted up Sonar and played around with the EQ and it now works like a dream. However, thinking that it was the buffer size that had been the problem, I looked again and noticed that the buffer size is actually still reading as 384. It hadn't changed for some reason. Whaaa?? I have a nasty feeling that this will be an intermittent problem. Does anyone know what might be going on?

Are you using ASIO? And which card are you actually using?
