The Roli Airwave is a high-tech keyboard teaching tool inspired by the theremin

Roli is no stranger to quirky musical instruments. After all, it pioneered the idea of a "squishy" MIDI controller. The company's latest tool, however, could be its weirdest. The Roli Airwave is an AI-infused piano teaching gadget that also doubles as a digital theremin. Yes, the same high-pitched theremin that has appeared on hit records like The Beach Boys' "Good Vibrations" and Erykah Badu's "Incense." The Airwave is basically a tall stand with a camera on top.
