The Yamaha DX7 was a synthesizer manufactured by the Yamaha Corporation from 1983 to 1986, based on FM synthesis developed by John Chowning. The United States dollar ( sign: $; code: USD) is the unit of Currency of the United States; it has also been Year 1983 ( MCMLXXXIII) was a Common year starting on Saturday (link displays the 1983 Gregorian calendar) Year 1986 ( MCMLXXXVI) was a Common year starting on Wednesday (link displays 1986 Gregorian calendar) A 220 Hz carrier tone modulated by a 440 Hz modulating tone with John M Chowning (born 1934 in Salem New Jersey) is an American musician inventor and professor best known for his work at Stanford University It was the first commercially successful digital synthesizer, with its sound included in many recordings from the 1980s. The 1980s was the decade spanning from January 1 1980 to December 31 1989. The DX7 was the moderate priced model of the DX series of FM keyboards that included the smaller DX9, DX100, DX11, DX21 and the larger DX5 and DX1.

One major reason for the success was the precision and flexibility of digital sounds. Although the DX7 was not a sampler, its bright sounds were much clearer than the analog synthesizers that preceded it. A sampler is an electronic musical instrument closely related to a Synthesizer. An analog synthesizer is a Synthesizer that uses analog circuits and Analog computer techniques to generate sound electronically Yamaha claimed that the DX7 used FM, but it actually implemented phase modulation synthesis. Phase modulation (PM is a form of Modulation that represents information as variations in the instantaneous phase of a Carrier wave. 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. From the root prefix mono meaning one and timbre meaning a specific tone of a sound independent of its pitch monotimbral is usually used in It has thirty-two algorithms, each being a different arrangement allowing the user to combine its 6 sound operators together dependently and/or independently.

Voices can be programmed by a user, and stored into a 32-voice ROM internal memory, or corresponding DX7 ROM cartridge. Several computer applications exist (mainly for Atari and Mac OS, and now Mac OS X) that can enable a user to load different presets into the keyboard from a computer via MIDI; the user can also store the keyboard's voices onto the harddrive to free up memory. The most prominent of these programs is Takashi Suzuki's DX7 Librarian 2. 1.

The synthesizer included MIDI ports, but was released shortly before the specification was completed, and has incomplete support for the standard: It only transmits information on MIDI channel 1. MIDI ( Musical Instrument Digital Interface, ˈmɪdi is an industry-standard protocol that enables Electronic musical instruments Computers It can receive information on any one of the sixteen MIDI channels at a time, but lacks the OMNI feature that enabled later DXs in the series to receive on all MIDI channels simultaneously. Very early DX7s manufactured in 1983 are distinctive for not having "MIDI Channel" inscribed next to the button that opens this function. This lack of marking was corrected by 1984.

An additional DX7 MIDI oddity is that the keyboard will not send velocity data beyond value 90 or so, while the maximum value permitted in MIDI is 127. The implication of this is that a user recording an expressive piano passage (or one consisting of a similar expressive voice) into a sequencer from the DX7 would not be able to achieve true fortissimo dynamics; most other MIDI keyboards could achieve this easily. The DX7 will, however, respond appropriately to these high velocity values when sent from an outside MIDI source.

Several improved "DX7 II" models were released between 1987 and 1989, most notably the DX7 II (FD) which improved sound quality and allowed bi-timbrality. Third-party products for the DX7 also flourished in the 1980s, including Grey Matter Response's E! expansion board, which added sequencer functions to the keyboard. A music sequencer (also MIDI sequencer or just sequencer) is software or hardware designed to create and manage computer-generated music DX7 IIs can transmit and receive on any one of 16 MIDI channels at a time. The DX7 family remains popular to this day with many recording and performing artists.

Rackmount versions of the DX7 also exist, ranging from the TX7 (a simple desktop DX7 unit, with limited editing abilities) to the TX802 (a DX7II in a 2-unit rack mount unit, with 8 outputs) and even the TX816 (eight DX7s in a large rack unit, with individual MIDI ports and balanced outputs for each module (via an XLR connector), giving the musician a massive 128 notes of polyphony). The XLR connector is an Electrical connector design XLR Plugs and sockets are used mostly in professional audio and Video

In 1988, in celebration of the company's 100-year anniversary, Yamaha released the DX7 II Centennial. Year 1988 ( MCMLXXXVIII) was a Leap year starting on Friday (link displays 1988 Gregorian calendar) It was a DX7 II FD with a silver case, gold painted buttons and sliders, and 76 glow-in-the-dark keys. Only 100 were made and were priced at US$3995.

Software Emulation

Native Instruments have developed a popular software synthesizer, FM8 (2006) (previously FM7 (2001-2006)), that emulates the DX7's digital circuitry and can load original DX7 patches. Native Instruments is a Music software production company whose products are mainly aimed at Electronic musicians The company was founded in 1996 FM8 is a commercial proprietary software synthesizer from Native Instruments. The sound is not completely identical to the actual instrument, however.

Program piracy

Since the DX7 allows users to program different tones, it is possible to "steal" someone else's synthetic sound for use in your own piece. Skilled programmers would go to great lengths to protect their sounds. "Various DX7 programmers have told me that they "bury" useless data in their sounds so that they can prove ownership later. Sometimes the data is obvious, like weird keyboard scalings on inaudible operators, and sometimes its not, like nonsense characters in a program name. "[1]
