John Chowning's work on FM synthesis from the 1960s to the 1970s allowed much more efficient digital synthesis, eventually leading to the development of the affordable FM synthesis-based Yamaha DX7 digital synthesizer, released in 1983.

Over the years, Lee's keyboards have featured synthesizers from Oberheim ( Eight-voice, OB-1, OB-X, OB-Xa ), PPG ( Wave 2. 2 and 2. 3 ), Roland ( Jupiter 8, D-50, XV-5080, and a Fantom X7 starting on the Snakes & Arrows Tour ), Moog ( Minimoog, Taurus bass pedals, Moog Little Phatty ), and Yamaha ( DX7, Yamaha KX76 ).

Tone generation in the DX7 is based on linear frequency modulation synthesis ( FM ), based on research by John Chowning at Stanford University.

This means that when using the original DX7 as a MIDI controller to play external sound modules, the patches on these modules must be adjusted to be more sensitive to velocity.

DX7 Mark II models resolved these deficiencies and were equipped with full MIDI implementation, including the ability to send and receive on any or all of 16 channels, send program change commands, controllers commands ( total of 103 parameters can be assigned to any controller ), and SysEx ( system exclusive ) messages, thus making them quite useful as a MIDI controllers for other synths and sound modules.

DX7 IIs were able to transmit and receive on any one of 16 MIDI channels at a time.

Yamaha wisely designed the DX7 II series such that voices produced on the original DX7 were compatible with the new models.

It essentially provides the core of a DX7, without the on board editing interface.

The DX7 Rhodes ( also known as DX Rhodes, FM Rhodes, FM E. Piano, or Digital Rhodes ) is a Fender Rhodes emulation, which originated from the " E. Piano 1 " patch on the Yamaha DX7 and TX-series rack mountable synthesizers.

The D-50 was introduced in 1987 as the popularity of the Yamaha DX7 was declining, resulting in the D-50 being the most popular synthesizer on the market until the introduction of the Korg M1 the following year.

When he played keyboards for Crowded House on tour during the late 1980's, he was seen to be using a Yamaha DX7 and a Yamaha Clavinova of some type.

This was the unit which produced the original demo of " Fire Island " ( based around two sequences programmed on a Yamaha DX7 ) at Planet Studios in Edinburgh, which subsequently came to the attention of the Beggars Banquet Records A & R department.

it represents an extensive investigation into the endless range of sounds that can be created by combining the venerable DX7 synthesiser and the even more venerable Chinese zither, the guzheng.

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 " struck " and " plucked " sounds which emphasize complex attack transients.

Voices ( sounds ) can be stored into the 32-voice RAM internal memory, or accessed via a corresponding 32-voice DX7 RAM cartridge, inserted into a front panel access door / port.

It also means that when playing the DX7's own sounds using an external MIDI controller or sequencer, the velocity values should be rescaled before the input to the DX7, or the DX7 patches would need to be adjusted to be less sensitive to velocity.

This meant that the DX7 II maintained backward compatibility with the vast base of existing DX7 sounds, which amounted to a major selling point for the new units.

The DX7 is capable of producing such a sound, but the difficulty of FM synthesis programming, combined with the immediacy of the stock DX7 sounds, usually meant that players performed and recorded with the sounds available at their fingertips.

This being the case, factory DX7 sounds flourished in recorded music in the 1980s.

CSound also has opcodes for producing DX7 sounds.

Since the introduction of the DX7, FM synthesis has distinguished itself for is its ability to create unique new sounds, rather than emulate existing instruments.

Faltermeyer recorded the song using five instruments: a Roland Jupiter-8 provided the distinctive " supersaw " lead sound, a Moog modular synthesizer 15 provided the bass, a Roland JX-3P provided chord stabs, a Yamaha DX7 was used for bell and marimba sounds and a LinnDrum was used for drum programming.

The ESQ-1 has a distinct sound, although the machine itself was overshadowed by other keyboards of the eighties, mainly other digitals like the Yamaha DX7, Roland D-50 and Korg M1 to name a few.

In addition to the Yamaha DX7, the advent of inexpensive digital chips and microcomputers opened the door to real-time generation of computer music.

Introduced in 1983, the Yamaha DX7 was an early all digital synthesizer that obtained relatively broad commercial success.

PM is used, however, in digital music synthesizers such as the Casio CZ synthesizers, or to implement FM Synthesis in digital synthesizers such as the Yamaha DX7.

The Prophet-5, one of the first polyphonic synthesizer s. It was widely used in 1980s synthpop, along with the Roland Jupiter-4 | Roland Jupiter and Yamaha DX7.

Marble Madness was Atari's first game to use an FM sound chip produced by Yamaha, which is similar to a Yamaha DX7 synthesizer and creates the music in real time so that it is in synchronization with the game's on-screen action.

At the time the genre arose, important synthesizers were the Korg MS-20, Emulator II, Oberheim Matrix and Yamaha DX7.

* 1986-1988: Sequential Circuits Prophet 10, Yamaha CP-70 electric grand piano, NED Synclavier ( ORK version ), E-mu Emulator II +, ARP Quadra, Yamaha TX816, Korg DVP, Yamaha DX7.

* Invisible Touch: Sequential Circuits Prophet 10, Yamaha CP-70 electric grand piano, NED Synclavier ( VPK version ), E-mu Emulator, ARP Quadra, Yamaha DX7.

The Yamaha DX7 is a FM Digital Synthesizer manufactured by the Yamaha Corporation from 1983 to 1986.

The DX7 was the moderately priced model of the DX series of FM / PM keyboards that included DX9, the smaller DX100, DX11, and DX21 and the larger DX1 and DX5.

While the instrument is monotimbral, it is notable how the sound of a single DX7 patch can change either subtly or wildly along the length of the keyboard or when played with different velocities.

The DX7 features 32 algorithms, each being a different arrangement of its six sine wave Operators, allowing for a great deal of programming flexibility.

The Yamaha DX7 earned a reputation of being difficult to program, primarily due to players being accustomed to the traditional synthesizer architecture of analog oscillators, filters, LFO generators, etc.

While other early digital synths used wavetable synthesis, this required considerable memory, which was simply cost-prohibitive in 1983 when the DX7 was introduced.

This resulted in the DX7 being demonstrably more capable than other devices in its price range.

Those who made effort to become proficient in programming the DX7 however, were rewarded with the full range of the instrument's expansive soundscape.
