Cyberstep sent our hearts aflutter-ish at last year’s NAMM with its prototype KDJ-One, a Game Boy with gigantism that held a portable digital audio workstation inside. Now, twelve months later, the company’s pulled the dust sheets from a version that’s ready for prime-time. Inside its roomy bowels you’ll find a 1.0GHz Intel Atom processor, 512MB RAM, 4GB SSD and a 5-inch WVGA (800 x 400) touchscreen that’ll let you control that piano-roll score editor. There’s also 15 chunky rubber LED-lit keys, a Jog dial, D-Pad and a rumble pack so you really know when you’ve got a poppin’ choon going. You’ll be able to pre-order the vanilla kit for $800, but for $830 you’ll also find WiFi baked inside, in either Game Boy White or Black’n’Red — but be warned, orders are said to be fulfilled within six months. After the break we’ve got some new footage of the unit being put through its paces, which at no point shows it being used to play Super Mario Bros, shame.
