It can be heard on many recordings from the 1980s. The DX7 was the moderately priced model of the DX series of FM keyboards that included the smaller DX9, DX100, DX11, DX21 and the larger DX5 and DX1. Over 160,000 DX7s were made. The was based on frequency modulation synthesis (FM) based on reasearch by John Chowning of Stanford University. The DX7 was known for precision and flexibility of its bright, digital sounds, which were much clearer than those of the analog synthesizers that preceded it. The DX7 is well-known for its electric piano, bells, and other "metal striking metal" sounds. It was monotimbral and capable of 16-note polyphony. It had 32 algorithms, each being a different arrangement allowing the user to combine its 6 sound operators together dependently and/or independently.
