Yamaha DX7

The Yamaha DX7 was a synthesizer which made use of Frequency Modulation (FM) Synthesis, released in 1983. The synth had a profound impact on the 80s music, and many of the preset sounds appear on many hits of the decade.

Sting's Yamaha DX7
On the Dream Of The Blue Turtles tour (1986 concerts), Sting occasionally played a Yamaha DX7 synthesizer onstage.

Kenny Kirkland played a DX7 on the album, and had used the marimba/xylophone preset on "Love Is The Seventh Wave", for example.

Stewart Copeland's Yamaha DX7
Stewart Copeland had a Yamaha DX7 synthesizer at his home in the mid-1980s. Although little is known about him using the synth (provided the Fairlight CMI was his preferred machine), it could have appeared in some of his film scoring work (such as The Equalizer) and possibly The Rhythmatist soundtrack.
