TH2 Producer GUI Causing Crackles?

Does play or record need to be engaged?

Do you have the 64 bit double engine on? Maybe still coming from there. 

I had also updated my video drivers in windows. I cant remember if this got the whole problem solved.

Ran a quick test before I ran for the door, nothing. Maybe try different display drivers.

I've found other VSTs that, when loaded in SONAR, even if their track is muted, cause pops and clicks (eg. MHC Fatsondo).  Freezing/bouncing & archiving the offending track solves the problem.

Hi, Craig,
do you have the latest version of the plugin? It's 2.2.16.

Just wanted to add that I too have had this problem. I don't use TH2 that much so haven't worked with it recently, nor have I had the chance to see how it performs with different/new video drivers at different latencies. The issue for me was moving the GUI from left to right and back again to access the different modules.
 

Cakewalk has spoken. Better mark this one as solved Craig.

Hi, Craig,
do you have the latest version of the plugin? It's 2.2.16.

Is this the (Sonar) producer version or the full version? How do you update the TH2 Producer version in Sonar?

X-Ray on?

The current 64bit full version is 2.2.16, TH2 Producer is 2.2.3.

Doesn't seem right to me, I wonder if it is related to this:
 
I wonder if it is related to this (it's not the exact issue, and no crackling involved either, post #46 summarises it):

Is TH2 locked to X3? If not I would be curious if you have the same crackles in earlier Sonar versions.  Perhaps you could try it out.
 
I have posted several times about crackles and pops I am having, and believe it could be a driver issue. But seeing posts like this makes me wonder if the source of the problem is something else. I too have found that bumping up to 1024 samples can help, but that it pretty high for moderate projects that ran at 128 or at most 256 with no problems on 8.5.

Turning off X-Ray didn't help either, but bumping up the latency to 1,024 samples did. Given that I can normally get by with 128, even on complex mixes, that seems like a lot. It's odd it happens only the TH2 Producer version, not the full one.

Odd indeed, that the premium edition of Sonar's currently bundled-in (tethered?) guitar amp/fx sim plug-in would be causing problems unless the latency were raised so high. Odd also that a CW developer's response is to blame it on Windows and recommending increasing latency. Makes one wonder to what extent CW actually tests compatibility of bundled-in plug-ins with their software on different systems (and with different graphics cards).
 
If only there someone in a position to exert some influence upon CW (and perhaps Overloud too) to satifactorily resolve this rather unfortunate situation....
 
(fwiw, I do understand what Keith meant about alpha blending, and am generally aware of the state of MS' graphics APIs including Direct2D, but stil found it rather disappointing that CW's only proffered remedy was to increase the latency)

Just to give another view. I don't suffer with this problem in the bundled version of TH2. So it's not an issue that everyone suffers. Apart from the video card, my system is nearly identical to Craig.
