Yamaha New musical Device: Tenori-On LED

Ha.... a Creative invention indeed !
Both a visual tool and musical one by Yamaha, this device creates music and helps you perform.

"Press an LED button briefly to play the sound assigned to it. At the same time the lights will flash outward from the played sound. If you hold the LED button a bit longer it will remain lit and will become an active note that will play repeatedly."

COOL !!!!
