The Yamaha Tyros2 is a digital arranger workstation 61-key keyboard produced by Yamaha Corporation in 2005. It was produced and designed by Kazuhisa Ueki and Soichiro Tanaka, respectively. The Tyros2 introduced several new features to the Tyros series, such as 'SuperArticulation! Voices', allowing for more realistic sounding voices during performances, and hard-disk recording allowing users to export audio recordings. Many features seen in the original Tyros returned to the Tyros2, including MegaVoice, primarily used in MIDI recording, which use velocity switching to add realism; Live!, Sweet! and Cool! voices, that are sampled using stereo and multilayered samples to better capture the natural presence expression and vibrato of the real instruments; and Internet Direct Connection, allowin
