You'll hear something different as soon as you play Tyros4's classical choir Voices: the sound is incredibly natural thanks to Ambient Sampling. For sampling, microphones are normally positioned close to the instrument to capture a direct sound which includes very little of the rooms ambience. For Tyros4's new classical choirs, the microphone positions were carefully adjusted to capture not only the sound of the choir but also the ambience of the room, resulting in unprecedented clarity and realism of sound.

Together with technologies such as Super Articulation, Tyros4's pop vocals use Yamaha's latest voicing technology, Wave Cycling, to bring hugely versatile vocal creativity to your performances. Tyros4 is packed with different vocal articulations such as Aah, Bah, Bee, Doh etc., and Wave Cycling varies the articulation of the Voice as you play. This means that you can now play incredibly realistic "shoo-bee-doo-bah" and scat vocals with remarkable ease!
