Reply to VFX-1 Controller - does anyone here use it?

I have one that I got a while back when I bought at VCI-300. However, ever since getting an X1, I haven't used it at all. Serato DJ, SSL, and Traktor all allow mapping of effects, and the number of controls on the X1 is just so much more. Also, it is a strange height and shape, and I'm not really sure where to fit it in amongst the mixer, tts, computer, and x1.

How do you use it in your workflow? What programs are you using? To me, it is just a awkward piece of gear that I'm not sure how to incorporate.
