Meet Keys, a modular musical keyboard that fits in your backpack and links with your iPhone

Keys is the first modular keyboard with full-sized LED keys that features gesture control, as well as PC and iPhone connectivity. In 2012, Opho, a San Francisco-based startup known back then as Incident Technologies, had one of the more successful Kickstarter campaigns, raising $350,000 for its digital guitar, gTar, on the crowdfunding site. Now it hopes to do even better with with the launch of its second product, Keys, a $100 portable -- and modular -- musical keyboard with full-sized LED keys, proximity gesture control, and a rechargeable battery. Keys is available for pre-order now for $100 and will ship early this summer.
