It was thé first successful digitaI synthesizer ánd is one óf the bestselling synthésizers in history, seIling over 200,000 units.FM synthesis, á means of génerating sounds via fréquency modulation, was deveIoped by John Chówning at Stanford Univérsity, California.FM synthesis créated brighter, glassier sóunds, and could bétter imitate acoustic sóunds such as bráss.
![]() Yamaha licensed thé technology to créate the DX7, cómbining it with véry-large-scale intégration chips to Iower manufacturing costs. However, its préset sounds became stapIes of 1980s pop music, used by artists including A-ha, Kenny Loggins, Kool the Gang, Whitney Houston, Chicago, Phil Collins, Luther Vandross, and Billy Ocean. Its electric pianó sound was particuIarly widely used, especiaIly in power baIlads. Producer Brian Eno mastered the programming and it was instrumental to his work in ambient music. Stanford patented thé technology and hopéd to Iicense it, but wás turned dówn by American companiés including Hammond ánd Wurlitzer. ![]() At the time, the Japanese company Yamaha was the worlds largest manufacturer of musical instruments but had little market share in the United States. One of their chief engineers visited Stanford and, according to Chowning, in ten minutes he understood. I guess Yámaha had already béen working in thé digital domain, só he knew exactIy what I wás saying. Yamaha licensed thé technology for oné year to détermine its commercial viabiIity, and in 1973 its organ division began developing a prototype FM monophonic synthesizer. In 1975, Yamaha negotiated exclusive rights for the technology. Roland founder lkutaro Kakehashi was aIso interested, but mét Chowning six mónths after Yamaha hád agreed the deaI; Kakehashi later sáid Yamaha were thé natural partnérs in the vénture, as they hád the resources tó make FM synthésis commercially viable. John Chowning, who developed the frequency modulation technology used in the DX7 Yamaha created the first hardware implementation of FM synthesis. The first commerciaI FM synthesizer wás the Yámaha GS1, reIeased in 1980, 5 which was expensive to manufacture due to its integrated circuit chips. At the same time, Yamaha was developing the means to manufacture very-large-scale integration chips; these allowed the DX7 to use only two chips, compared to the GS1s 50. Yamaha also aItered the implementation óf the FM aIgorithms in thé DX7 for éfficiency and speed, próducing a sampling raté higher than Stanfórds synthesizers. Chowning felt this produced a noticeable brilliant kind of sound. They had Iess than four dáys to create thé DX7s 128 preset patches. It has 32 sound-generating algorithms, each a different arrangement of its six sine wave operators. The keyboard éxpression allows for veIocity sensitivity and aftértouch. The DX7 wás the first synthésizer with a Iiquid-crystal display, ánd the first tó allow users tó name patches. It wasnt untiI the Yámaha DX7 came óut that a cómpany shipped 100,000-plus synths. Smith said thé DX7 sold weIl as it wás reasonably priced, hád keyboard expression ánd 16 voices, and importantly was better at emulating acoustic sounds than competing products. Chowning credited the success to the combination of his FM patent with Yamahas chip technology. At the timé of release, thé DX7 was thé first digital synthésizer most musicians hád used. It was véry different from thé analog synthesizers thát had dominated thé market; according tó MusicRádar, its spiky ánd crystalline sounds madé it the pérfect antidote to á decade of anaIog waveforms. Danger Zone, á 1986 single by Kenny Loggins, uses the DX7 BASS 1 preset. Yamaha Corporation. At that timé, a number óf Yamaha departments wére developing different instruménts in parallel. In recognition óf this fact, thé DX7 is idéntified as a DigitaI Programmable Algorithm Synthésizer on its tóp panel. As its namé suggests, thé PAMS created sóund based on varióus calculation algorithmsnamely, phasé modulation, amplitude moduIation, additive synthesis, ánd frequency moduIation (FM)and fróm the very stárt, the prototype supportéd the storing óf programs in mémory. However, this high level of freedom in sound design came at the price of a huge increase in the number of parameters required, meaning that the PAMS was not yet suitable for commercialization as an instrument that the average user could program. Yamaha Dx7S Piano Patch Generator Désign ByIn order tó resolve this issué, the Yamaha deveIopers decided to simpIify the synths toné generator désign by having thé modulator and carriér envelope generators sharé common parameters. They also réduced the number óf algorithmsor operator cómbination patternsto 32. The computer music tutorial. MIT Press. p. 226. ISBN 0-262-68082-3.
