Reply to The Leo Bodnar device - A little help...?

I have bought the Leo Bodnar HID device and I've filled the digital button outputs and used 6 of the analogue inputs for faders/pots. I was wondering if I could put a joystick in to the two remaining analogue inputs and use it as an x-y controller. I'm really not sure if this would work.

Also, what are the 4 inputs on the bottom/middle of the unit (Up, down, left, right). Can these be used for additional buttons?

Ooops, nearly forgot to put in the link...http://www.leobodnar.com/products/BU0836X/

Any help would be really appreciated as I'm looking to make the final cuts on my case this weekend (If the Alps faders arrive in time).

Cheers.

Archie.
