I'm contemplating finally upgrading from X1 Producer Expanded to X2, but I love the Concrete Limiter and a couple of the other ProChannel Modules I've had since I upgraded to Producer Expanded last year sometime. So, do I get to use my current ProChannel Modules in X2 if I upgrade? Thanks in advance for your support and feedback!

All modules work in X2. Plus the ones that come with it. 

Yes, they all transfer.

Thanks John and Lynn! Good to know as I couldn't find the answer after searching the website and the forum.
