Superb little keyboard
I've had this for quite some time now and find it very useful indeed. I have a lot of keyboard apps triggered by Xkey. It's useful for scratching an itch just to do something quickly ! Also I find it useful if I'm picking up a new piece and haven't got the sheet for it. It's not a main piece of gear or anything but to be honest I wouldn't be without it now.

Decent Midi controller
Useful portable MIDI keypad that takes a little getting used to if you are used to keys but is fun to use.
