I found a bug in the vst amp rack. I cant use the effects(pre/post). Only A white box shows up.
The eq does not work either. i think this plugin needs more work in C7.
The same here.
But there is a small solution, 
check this box blank and reopen the menu … will be all right.
For now, though this is a bummer 
, we can live with this and give preference to other errors such as compressors …

Sorry to be heavy with this subject but as yet no one gives me an answer …
