Is this really the only way to contact synapse for help?
Anyways, if you load an instance of GEQ7 into any project you'll get crackling (from very small to large projects) The problem seems to be the analyzer. If you turn it off, it seems to be ok. I've also noticed that though it's nowhere near as pronounced, even the 8.2 release version can run into this with enough instances.
I'm win7x64, i7 4770, and using version 82 of the 8.3 beta.
