Uhmmmmmmmmm............... Been playing with X3 for days now and just found out I am missing something today when editing. Where is my Sonitus: FX Suite at? I can understand adding new effects but taking away is not cool since we have paid for the product. Can't find Sonitus: FX Suite since I have upgraded form X2 Producer to X3 Producer. Any one else missing?

If you haven't already, rescan your plug-ins. I have all my Sonitus stuff.
 

Sonitus has not went anywhere:

It's listed as included and everyone else seems to have it, myself included.  Definitely do as emwhy suggested.

Isn't Sonitus still DX? If so, the VST scanner won't pick them up.

Actually, the scanner does discover DX plugins, but only if they've already been registered. Unless Windows has been re-installed since the X2 install, they should already be registered. To find out, open X2 and see if they show up. If they do, then the plugins are properly registered and a re-scan is all that's needed to show them in X3.

Yep, they are still there. And they come with X3. I do a custom install and X3 showed them as a component of the install procedure.
