If you're a wind instrument player who's been looking for a unique way to get into MIDI, the Akai EWI4000s is your chance. It's one of the only wind controllers, which measures the velocity of how hard you blow into it in order to play. The EWI4000s has controls for expressive performance that can be mapped in any way you choose, whether like a sax or a keyboard or a flute, and comes with onboard sounds that emulate analog synths with its powerful oscillators and filters. In-built effects like reverb and chorus give you the ability to customize your sounds.
