Simple synthesizers are great for kids who are interested in music, and a pair of Dutch designers have built another instrument that does just that. The Dato Duo is two-panel synth features an 8-step sequencer on one side with the sound controls and effects on the other. It seems a bit odd at first, but the idea is to have one person control each to enhance the collaborative efforts. There's also no wrong way to use the device, so even the youngest noise makers can get started with ease. And it doesn't hurt that the Duo sounds pretty good either.
