What version of Sonar are you using? 8.5, X1 or X2. BeatScape is not included with X2. I think the idea here is the Matrix View will replace BeatScape. I love Perfect Space. Maybe the pops and clicks could be latency issues within the plug-in itself.
I redid my hard drive and reinstalled X2 after the quick fix was released. I installed BeatScape from X1 because I wanted to have the content. I am not sure how much difference the content is between BeatScape and the default loop stuff that comes with X2.
The Matrix View works much better than BeatScape in my opinion. Just out of curiosity what are your new system specs? Congratulations on your new system. Hope it works well for you.
