I really want the nano pad with x y controller and the pads. Currently I'm using reason but I have ableton as well which I'm about to install and mess around with for a while. My room mate has this book that tells you everything about Ableton which should make for some good bathroom reading material.
On another note, my room mate is about to purchase this bad boy soon...
Specifically made to interact with ableton, so I'm really anticipating to see how this thing works.
