I've seen here in the forum and elsewhere that Sampletank 3 VST 3 version may not work properly in Sonar Platinum.  I'm having an issue where in the vst3 version, none of the outputs 17 and higher pass any audio data through to the tracks.  Outputs 1-16 work just fine, but 17-32 are completely silent.  As a trial, I unloaded the vst3 and loaded the vst2 version, and everything works as expected.  Has anyone else had this issue?  If so, is there a way to fix it?  I have not contacted IKM support, wanted to check here first.  Thanks in advance for any suggestions.

Yes, I can confirm that the latest version 3.6.1 still exhibits that behavior. 

Same here, well not that particular issue, but other malfunctions that don't happen with the VST2 version.  Now I always load the VST2 version. I concluded that it's one of those areas where the plugin blames the DAW and the DAW blames the plugin so I didn't start the weary march to complain.
