I'm having a tough time with this one! I load an instance of Dimension Pro. Select a bass sample from "real basses". I play the keys on my keyboard and all is well. Everything is snappy the way it should be, but only for a few minutes. Then without warning I strike a key on my keyboard and the latency is so bad the bass sounds more like a cello with a very slow, delayed response. I changed midi cables, experimented with different buffer settings, (Although I never had to mess with buffer settings before) reinstalled my sound card driver's and made sure Windows is up to date. I finally did a complete install of Windows and Sonar X3. The problem still persists. Any ideas as to what I can try next?

Interface: Scarlett 18i20; Win 7 64 on an AMD Quadcore. All specs in my sig.

Thanks

Latency is affect pitch or just slow keyboard response? If it is slow keyboard response, try typing "E" to temporarily disable all effects. If that fixes the problem, there are plug-ins which are causing PDC to kick in adding latency to the project.

Thanks Scook. This is a single instance of Dimension Pro (no other tracks/softsynths loaded) with no plugins at all. When pressing a key on the keyboard the response is normal at first but then just turns into mush. Very delayed, slow response.

It does seem strange. Are you looping or just playing the keyboard? Does the problem go away if the audio engine is toggled off/on?

Just playing. haven't tried turning the audio engine off. I'll give that a try now.

Hmmmm? Now everything seems to be working. No delay when playing my keyboard or latency with the audio engine on and off.

Does this mean the problem went away by itself? (gremlins)
Does this mean toggling the audio engine fixes the latency? (still a problem)

It seemed to just go away but I don't think it's solved yet. intermittent issues are the worst but so far there are no issues.

I agree, intermittent issues can be difficult to sort out. Maybe look in the Windows Event log for clues.

Will do. Thanks Scook
