Probably will have it sorted by then, at least a work-around. I've waited too long for a 64bit version to cancel now...

As I posted in the thread above, the problem only happens for me with VST3, not VST2, and others have posted similar behavior. So I actually already posted the (potential) workaround before your post. :)
 
Curious to see if anyone is having this problem with VST2.

Glad to see IK weighing in, I hope there's a solution soon. I raised a ticket with IK UK.
My issues in Sonar using a simple test project with just eight notes:
- Pressing play, some of the notes sound, some don't. Replaying, different notes play and those that did play first time don't now.
- Clicking on a note it sounds continuously until I press play and stop.
 
I'm using VST3 but I don't see why I should install the VST2 version, unless it's just for a temporary work around.
It seems to me there could not have been a beta tester using Sonar X3?
 
ST3 works perfectly in Studio One 2 which I have on the same PC, which is well spec'd, see signature below.

The vst3 version and standalone have a couple of issues. I don't seem to get this bug with VST 2.

I've raised the issue at very least for a good post mortem requesting more testing with Sonar to avoid issues like this in the future.  There may be some back and forth here on this forum, but please know that I'm doing my best to bring your specific needs to the right people when I can do so and making those issues and needs land squarely on their radar.  I hope it helps, I'm trying to be both constructive and realistic as I do, and hope that internally we learn something from each release and in this case that we learn to give more attention to Sonar based on your experience and your feedback here.

There are a few VST3 Issues in X3. Several synths in the Arturia V collection crash X3 if you use the VST3 versions but the VST2 works fine.

I avoid VST3 now if I have a choice.

OK guys, perhaps a stupid question, but what real advantages are there with Sampletank 3 for instance in using VST3 as opposed to VST2?
