I didn't get any vst3 plugs after my scan, should I have some?

 
Hi Al
 
With X3 Producer, you should have the VST3 versions of both the CA-2A and Melodyne Essential plug-ins.
 
The quickest way to find them is to first open the Browser, click on the PlugIns tab and choose Default All Plug-ins from the options in the drop-down menu:
 

 
Now you should see the VST3 folder listed, if you expand it, you should see that it contains the two plug-ins:
 

 
 
 

great info you should work for support ;-)

That is if
a) you purchased the CA2A and
b) you installed the VST3 version of the CA2A
X3 does not ship with the CA2A

detailed info you should never work for support ;-)

If I insert an effect in the track bin I have a vst3 category, but in the browser there is none, I have not purchased the ca2a.

Strange
