I received an answer from Izotope support and they were not able to reproduce the crackling on a system such as mine but his guess is that it may be graphics card related in that it may be eating away some the CPU cycles. He suggested that I try to reduce the number of meters running concurrently to see it that helps.
His reply as to the stereo field hard panning left is as follows:
"In regards to the stereo vectorscope issue, this has to do with the way Sonar X2 is channelizing the plugin. To fix this issue, go to the Insight options page, and under the I/O tab, set both drop-down menus in here to 'SMPTE'. You may want to save this as a preset for use in future projects that use Insight."
This fixed my stereo vectorscope issue and it works fine now.
I tried his suggestion on the crackles and it works but intermittently. I think I just need to spend some more time with it and all will be well. As the complexity goes up so does the learning curve...
@Bit - Don't know if you have tried the demo for Ozone 5 advanced but the fact that you can insert individual modules vs. the channel strip approach really is the berries and AudioDeluxe has some great upgrade prices for folks that already own Ozone 1-4.
Kind regards,
