Pardon My Stupidity but...

How do you know if you have KDFX or not.. Is there some way to check?? I bought mine used, so I'm not really sure.. Thanks

You should see it when you go to "effects" mode. Or take a program or setup: here you have 'effects', which is the standard effect. Now search for soft buttons that are named with KDFX.

You can also check for KDFX in the Diagnostics that you can access on startup.
