Awfully thin and weak sounding analog sounds. Have a listen to the original Eurythmics song and you'll quickly realize Yamaha's vintage synth pack bores no resemblance to true analog sounds used by Dave Stewart. The attempt was a valiant effort, the Tyros 4 just wasn't the correct instrument to pull it off.

For those interested the song used a Roland SH-09 and CSQ-100, Juno 6, Oberheim, and Movement Drum Computer.
