Monome

Monome consists of backlit keypads that will light up when pressed to mark where a note will be played. The device connects to the PC via USB, and the interaction between keys and lights will be determined by the application running on the computer. It is available in three versions. The 256 button, 128 button and 64 button Monomes will retail for $1,400, $800 and $450, respectively. [LikeCool]
