Cheers guys
Don't get the option for RMX with ASIO - it looks like this:

but setting it to Dual Stereo has brought the crossfade & volume controls into play.
Nothing in my headphones - is there something in the options I need to do or is it on the main screen?
Bought the software last week & cut n paste the serial directly from the download - where can I find it to register it here?
Can't get my 1210s playing through the controller either but I'm guessing that that's a Hercules not Cross DJ issue....
Thanks for your help to far.
Dan - whose the user with a similar set up on the Forum?
