Packing all the features of a full-size keyboard into something the size of Keys is not easy. To do so, the creators of the USB MIDI instrument got clever by implementing gesture controls to add functionality. What does that mean? Well, simply wave your hand up and down over some keys to add vibrato or change octaves by swiping to the side. The lightweight and super portable keyboard can work with an app to teach you some skills and also with other CoreMIDI supported apps to give the tiny keyboard a world of use. If one isn’t enough, you can link multiple together to make a larger device. And since it’s built from plastic reinforced with PCB, it can withstand the rigors of the road.
