Hi,
Serato ITCH is only available for use with ITCH controllers. Its designed to be a digital DJ'ing solution without the need for Turntables and CDJ's. At this stage we have no plans to implement a control CD or vinyl for use with ITCH.
I can see from your comments above that Scratch Live isn't for you, but I thought I would mention that you can use Scratch Live hardware with CDJ's, here is a brief explanation of how you can do it:

As a sidenote, also letting you know that Serato DJ is now available for use with the DDJ-S1.
Let me know if this helps!
Cheers, Sam
