Expand the instrument by connecting another keyboard, or attach it to another "block" for percussion, looping, or mixing. While the soft, pressure-sensitive surface of this block—a texture that feels more like human skin than a keyboard—takes some getting used to, it allows the player to control elements like the strike, glide, and lift of notes. The keyboard connects wirelessly over Bluetooth or can be plugged into your computer via a micro USB cable. It comes with a library of sounds, but you also have the ability to purchase extra sound packs or use their Equator Player to create your own synths. $300.
