36-554: The JD-800 employs sample-based oscillators and a fully digital signal path. This is different than Linear Arithmetic synthesis (introduced and made famous by the Roland D-50 ), which combines sample playback with digital synthesis . The JD-800 has 108 built-in sampled waveforms, which can be expanded via PCM cards. The waveforms span a variety of categories such as analog synthesizers, acoustic instruments, and voices. Many of these waveforms are very short and are used primarily for

72-593: A 1987 issue of Keyboard . Eno used the DX7 on records he produced by U2 and Coldplay . In later years, the DX sounds came to be seen as dated or clichéd, and interest in FM synthesis declined, with second-hand digital synthesizers selling for less than analog. The development of software synthesizers such as Native Instruments FM8 led to a resurgence in the popularity of FM synthesis. According to Sound on Sound , throughout

108-453: A PCM transient begins a note, which is then continued with a subtractive synthesis prolongation. Roland did not use the term additive , as additive synthesis already refers to a different synthesis method. This technology first appeared in 1987, in the Roland D-50 synthesizer. At the time, re-synthesizing samplers were very expensive, so Roland set out to produce a machine that would be easy to program, sound realistic, and still sound like

144-463: A decade of analog waveforms". It was praised for its accuracy in reproducing tubular bells , metallophones and the harpsichord , and took over the electric piano market. With complex submenus displayed on an LCD and no knobs and sliders to adjust the sound, many found the DX7 difficult to program. MusicRadar described its interface as "nearly impenetrable", with "operators, algorithms and unusual envelopes ... accessed through tedious menus and

180-575: A diminutive display". Rather than create their own sounds, most users used the presets. The presets were widely used in 1980s pop music. The "BASS 1" preset was used on songs such as " Take On Me " by A-ha , " Danger Zone " by Kenny Loggins , and " Fresh " by Kool & the Gang . The "E PIANO 1" preset became particularly famous, especially for power ballads , and was used by artists including Whitney Houston , Chicago , Phil Collins , Luther Vandross , Billy Ocean and Celine Dion . In 1986, it

216-430: A larger display, and the ability to expand the device with PCM cards for extra sounds. The JD-800 was expandable by the inclusion of slots for PCM cards (for additional wavesforms), and RAM cards (for additional patches). Roland produced a number of expansion kits consisting of a pair of cards — a PCM card containing new samples, and a RAM card containing a bank of new presets. Roland later released eight add-on cards for

252-473: A mainstay of subsequent flagship Yamaha products, such as the Yamaha EX5, Motif , and Montage lines — which still use the umbrella term AWM2, though the engine's details have changed many times. Casio has also developed a similar synthesis system known as Advanced and High Quality Large Waveform , better known as AHL, for use on their portable keyboard line. Earlier Casio keyboard models instead use ZPI,

288-640: A pitch envelope, a programmable equalizer, and on-board effects such as reverberation and chorus. Two tones grouped together created a patch . Yamaha's SY77 , its rack-mount equivalent TG77 , and successor SY99 introduced Advanced Wave Memory 2 (AWM2), enabling playback and digital filtering of samples. Notably, these also let AWM2 samples be used as transients to Advanced FM (AFM) synth sounds, as looped oscillators in their own right, or even as modulators of AFM carriers. This, like LA, enabled more realistic modeling of physical instruments, and in combination with FM, new possibilities for synthesis. The SY99 seemed to be

324-511: A similar but more advanced system. AHL was originally a simplified version of the previous ZPI, in which both are mostly optimized for acoustic instrument samples. Ensoniq with the SQ-80 called the same technique Cross Wave Synthesis. Kawai with the K4 called the same technique Digital Multi Spectrum. Korg's Modwave engine was designed to do both the morphing wavetable and sample synthesis, along with

360-465: A synthesizer. Also, Yamaha had previously gained world market lead with their DX7 FM synth , which excelled at metallic, percussive sounds—something that Roland's synths using subtractive synthesis were less good at. Roland understood that their subtractive synthesis method had to change. One of the more complex parts of a sound to program is the attack transient , so Roland added a suite of sampled attack transients to subtractive synthesis. As well as

396-458: The keyboard expression allows for velocity sensitivity and aftertouch. The DX7 has 16-note polyphony , meaning 16 notes can sound simultaneously. It has 32 sound-generating algorithms, each a different arrangement of its six sine wave operators. The DX7 was the first synthesizer with a liquid-crystal display , and the first to allow users to name patches. The DX7 was the first commercially successful digital synthesizer and remains one of

432-413: The 61 different keys on the keyboard, so is used for drums and percussion sounds. The JD-800 has one effects section. In Single mode, seven effects can be used simultaneously, in series, so all tones in a patch go through the same effects. In Multi mode, three effects can be used at the same time, with all patches sharing the same effects, though any of the patches can be routed to bypass the effects. Using

468-711: The CSDX in reference to the Yamaha CS range of analog synthesizers. In late 1982, Dave Bristow and Gary Leuenberger, experts on the Yamaha CS-80 , flew to Japan to develop the DX7's voices . They had less than four days to create the DX7's 128 preset patches. Compared to the "warm" and "fuzzy" sounds of analog synthesizers , the digital DX7 sounds "harsh", "glassy" and "chilly", with a richer, brighter sound. Its presets constitute "struck" and "plucked" sounds with complex transients . Its keyboard spans five octaves , and

504-571: The DX7 sound chip , such as the YM2612 , were used in technologies such as the Sega Genesis game console. The DX7 was succeeded by FM synthesizers including the DX1 , DX21 , DX27 and DX100 . In later years, the DX7 sounds came to be seen as dated or clichéd and its use declined. By the mid-20th century, frequency modulation (FM), a means of carrying sound, had been understood for decades and

540-469: The DX7 in depth. However, its preset sounds became staples of 1980s pop music ; in 1986, it was used in 40% of the number-one singles on the US Billboard Hot 100 . Its electric piano sound was particularly widely used, especially in power ballads . The English producer Brian Eno was proficient at programming his own sounds, and it was instrumental to his work in ambient music . Chips based on

576-530: The JD 800: Linear Arithmetic synthesis Linear arithmetic synthesis , or LA synthesis , is a means of sound synthesis invented by the Roland Corporation when they released their D-50 synthesizer in 1987. LA synthesis combines traditional subtractive synthesis with PCM -based samples. The term linear arithmetic refers to synthesis that puts sounds together in a timeline. Typically

612-511: The JD-800 consists of up to four tones. As every tone consists of an almost completely independent synthesizer voice, a patch could be considered a combination of up to four different synthesizers. In Single mode the JD-800 plays one patch at a time, but in Multi mode it is possible to play five different patches over MIDI , plus a "special" patch. The special patch has different waveforms assigned to

648-570: The Layer buttons, the four tones of a patch can be switched on and off while playing. When in Edit mode, the Layer buttons are used to choose which tone can be edited using the sliders on the front panel. The Palette sliders allow the player to edit the last active parameter of all four tones individually at the same time. While playing, the Palette sliders can be used like a mixer to set the balance between

684-526: The attack portion of a sound, while longer ones are used for the sustained part of a sound. The JD-800 was Roland's first instrument to have its core presets developed entirely in the United States, under a short-lived branch of its R&D-LA office in Culver City, California. The core sampled waveforms and factory presets of the JD-800 were created by Eric Persing . A patch, or single sound, in

720-480: The attack transients, Roland added a suite of single-cycle sampled waveforms that could be continuously looped. Sounds could now have three components: An attack, a body made from a subtractive synth sound (saw or pulse wave through a filter) and an "embellishment" of one of many looped samples. (The looped samples also contained a collection of totally synthetic waves derived from additive synthesis, as well as sequences of inharmonic wave cycles. Thus, LA synthesis offered

756-473: The bestselling synthesizers in history. According to Bristow, Yamaha had hoped to sell more than 20,000 units. Within a year, orders exceeded 150,000 units, and Yamaha had sold 200,000 units after three years. The DX7 was the first synthesizer to sell more than 100,000 units. Yamaha manufactured units on a scale American competitors could not match; by comparison, Moog sold 12,000 Minimoog synthesizers in 11 years, and could not meet demand. The FM patent

792-467: The deal. Kakehashi later said Yamaha were the natural partners in the venture, as they had the resources to make FM synthesis commercially viable. Yamaha created the first hardware implementation of FM synthesis. The first commercial FM synthesizer was the Yamaha GS1, released in 1980, which was expensive to manufacture due to its integrated circuit chips. At the same time, Yamaha was developing

828-500: The digital domain, so he knew exactly what I was saying." Yamaha licensed the technology for one year to determine its commercial viability, and in 1973 its organ division began developing a prototype FM monophonic synthesizer . In 1975, Yamaha negotiated exclusive rights for the technology. Ikutaro Kakehashi , the founder of the Japanese company Roland , was also interested, but met Chowning six months after Yamaha had agreed to

864-555: The early 1980s, the synthesizer market was dominated by analog synthesizers . FM synthesis , a means of generating sounds via frequency modulation , was developed by John Chowning at Stanford University , California. FM synthesis created brighter, glassier sounds, and could better imitate acoustic sounds such as brass and bells. Yamaha licensed the technology to create the DX7, combining it with very-large-scale integration chips to lower manufacturing costs. With its complex menus and lack of conventional controls, few learned to program

900-510: The four tones in a patch. However, due to the limited accuracy of the sliders, and because edited parameters jump from the value in memory to the value corresponding to the position of the slider, moving the sliders while playing tends to cause sudden jumps in the sound. The JD-800 manual states: "[T]he original purpose of the synthesizer was to 'create sound'. It's easy to simply select a preset you like, but that sound will always be 'someone else's sound'. We at Roland asked, 'Why don't we return to

936-518: The last FM workstation by Yamaha, and the later FM synth FS1R did not feature AWM — so SY99 was seemingly the last synthesizer to combine AWM with fully-fledged FM. This was until the Montage in 2016, which combines a later version of AWM2 with FM-X (an offshoot of the FM engine from FS1R, without the latter's Formant Synthesis) - though without letting samples be used as modulators, as the 77/99 series did. In any case, AWM sampling on its own has become

972-465: The means to manufacture very-large-scale integration chips. These allowed the DX7 to use only two chips, compared to the GS1's 50. Yamaha also altered the implementation of the FM algorithms in the DX7 for efficiency and speed, producing a sampling rate higher than Stanford's synthesizers. Chowning felt this produced a noticeable "brilliant" sound. Yamaha displayed a prototype of the DX7 in 1982, branded

1008-508: The mid-1980s, "Yamaha flooded the market with a plethora of low-cost FM synths." In 1987, Yamaha released the DX7II, which did not match the success of the DX7. Further successors included the TX81Z , DX1 , DX11, and DX21 . Yamaha manufactured reduced versions of the DX7 sound chip , such as the YM2612 , for use in technologies such as the Sega Genesis game console. In 2015, Yamaha released

1044-474: The realistic sounds of a sampler with the control and creativity of a synthesizer.) The PCM waveforms could be modified with a pitch envelope and a time-variant amplifier. Waveforms from the sound wave generators could be further modified with time-variant filters for cutoff frequency and resonance. These modified waveforms were called "partials". Two partials grouped together created a tone . Tones could be modified using up to three low-frequency oscillators ,

1080-476: The roots of synthesis; the enjoyment of creating original sounds?' … 'Creating sounds' may seem like a highly technical process, but it's actually just a matter of moving a slider to make the sound change! This is easy for anyone, and the sounds that you get will always be your very own." Roland released the JD-990 Super JD in 1993. This is an enhanced, rackmount sound module version of the JD-800 with

1116-462: The usage of MS-20 filters due to its slope, which makes it closer to Roland's D-50 / D-550 / D-05 LA synthesizers. Some features are limited to layers instead of individual oscillators (e.g. filters). Yamaha DX7 The Yamaha DX7 is a synthesizer manufactured by Yamaha Corporation from 1983 to 1989. It was the first successful digital synthesizer and is one of the best-selling synthesizers in history, selling more than 200,000 units. In

1152-470: Was for years one of Stanford's highest earning. Chowning received royalties for all of Yamaha's FM synthesizers. According to Dave Smith , the founder of the synthesizer company Sequential , "The synthesizer market was tiny in the late 70s. No one was selling 50,000 of these things. It wasn't until the Yamaha DX7 came out that a company shipped 100,000-plus synths." Smith said the DX7 sold well as it

1188-505: Was reasonably priced, had keyboard expression and 16 voices, and was better at emulating acoustic sounds than competing products. Chowning credited the success to the combination of his FM patent with Yamaha's chip technology. At the time of release, the DX7 was the first digital synthesizer most musicians had used. It was very different from the analog synthesizers that had dominated the market. According to MusicRadar , its "spiky" and "crystalline" sounds made it "the perfect antidote to

1224-455: Was turned down by American companies including Hammond and Wurlitzer . Chowning felt their engineers did not understand FM. At the time, the Japanese company Yamaha was the world's largest manufacturer of musical instruments but had little market share in the United States. One of their chief engineers visited Stanford to view the technology. According to Chowning, "In ten minutes he understood ... I guess Yamaha had already been working in

1260-598: Was used in 40% of the number-one singles on the US Billboard Hot 100 , 40% of country number ones, and 60% of RnB number ones. The preset imitates a Rhodes piano , prompting some to abandon the Rhodes in favor of the DX7. A few musicians skilled at programming the DX7 found employment creating sounds for other acts. The English musician Brian Eno learned to program the DX7 in depth and used it to create ambient music on his 1983 album Apollo: Atmospheres and Soundtracks . He shared instructions for recreating his patches in

1296-404: Was widely used to broadcast radio transmissions . In the 1960s, at Stanford University , California, John Chowning developed FM synthesis , a means of using FM to generate sounds different from analog synthesis . In 1971, to demonstrate its commercial potential, Chowning used FM to emulate acoustic sounds such as organs and brass. Stanford patented the technology and hoped to license it, but
