Frequency modulation synthesis is a form of sound synthesis whereby the frequency of a waveform is changed by modulating its frequency with a modulator. The (instantaneous) frequency of an oscillator is altered in accordance with the amplitude of a modulating signal.
A music workstation is an electronic musical instrument providing the facilities of:
The YM2612, a.k.a. OPN2, is a sound chip developed by Yamaha. It is a member of Yamaha's OPN family of FM synthesis chips, and is derived from the YM2203.
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.
Yamaha XG is an extension to the General MIDI standard, created by Yamaha. It is similar in purpose to the Roland GS standard.
The Yamaha TX81Z is a rack-mounted (keyboard-less) frequency modulation (FM) music synthesizer, released in 1987. It is also known as a keyboard-less Yamaha DX11. Unlike previous FM synthesizers of the era, the TX81Z was the first to offer a range of oscillator waveforms other than just sine waves, conferring the new timbres of some of its patches when compared to older, sine-only FM synths. The TX81Z has developed a famous reputation, largely based on some of its preset bass sounds. The Yamaha DX11 keyboard synth was released the following year, offering improved editing abilities.
The Yamaha Motif is a series of music workstation synthesizers, first released by Yamaha Corporation in August 2001. The Motif replaced the EX series in Yamaha's line-up and was also based on the early Yamaha S series. Other workstations in the same class are the Korg Kronos and the Roland Fantom G. The series' successor is Yamaha Montage, released in 2016, followed up by the Yamaha Montage M in 2023.
The AY-3-8910 is a 3-voice programmable sound generator (PSG) designed by General Instrument (GI) in 1978, initially for use with their 16-bit CP1610 or one of the PIC1650 series of 8-bit microcomputers. The AY-3-8910 and its variants were used in many arcade games—Konami's Gyruss contains five—and Bally pinball machines as well as being the sound chip in the Intellivision and Vectrex video game consoles, and the Amstrad CPC, Oric-1, Colour Genie, Elektor TV Games Computer, MSX, Tiki 100 and later ZX Spectrum home computers. It was also used in the Mockingboard and Cricket sound cards for the Apple II and the Speech/Sound Cartridge for the TRS-80 Color Computer.
The Korg MS2000 is a virtual analog synthesizer produced by the Japanese electronic musical instrument manufacturer Korg.
Linear arithmetic synthesis, or LAsynthesis, is a means of sound synthesis invented by the Roland Corporation when they released their D-50 synthesizer in 1987.
The Yamaha V50 is a hybrid music workstation introduced in 1989. It combines a sequencer, rhythm machine, an FM synthesis-based sound module and a MIDI keyboard.
The YM2203, a.k.a. OPN, is a six-channel sound chip developed by Yamaha. It was the progenitor of Yamaha's OPN family of FM synthesis chips used in many video game and computer systems throughout the 1980s and early 1990s. It was used in a variety of NEC computers, along with various arcade game machines.
The Yamaha YM2164, a.k.a. OPP, is an FM synthesis sound chip developed by Yamaha, an enhanced version of their YM2151. The OPP was used in various MIDI-based synthesizers by Yamaha - DX21, DX27, DX100, SFG-05, FB-01 - plus several licensed products: the IBM Music Feature Card and Korg's DS-8 and Korg 707.
The Yamaha YS200 is an FM synthesiser and workstation produced by Yamaha, introduced in 1988. It combines a sequencer, rhythm machine, an FM synthesis soundchip and a MIDI keyboard. It was called the EOS YS200 in Japan and was also released as a more home-oriented keyboard in the form of the Yamaha EOS B200, which also featured built-in stereo speakers. The YS200 is the keyboard equivalent of the Yamaha TQ5 module. The forerunner of the YS200 was the almost-identical Yamaha YS100.
The Yamaha YM2154, also known as RYP4, is an audio microchip that was produced by the Yamaha Corporation. It been used for keyboards and drum machines. It has twelve individual samples and also an ADPCM Rompler and a ten channel Analog-to-digital converter.
The Yamaha DX21 is a digital controlled bi-timbral programmable digital FM synthesizer with a four operator synth voice generator which was released in 1985. It uses sine wave-based frequency modulation (FM) synthesis. It has two FM tone generators and a 32-voice random-access memory (RAM), 32 user voices and 128 read-only memory (ROM) factory preset sounds. As a programmable synth, it enables users to create their own unique synthesized tones and sound effects by using the algorithms and oscillators. The instrument weighs 8 kg (17.6 lbs). On its release, it sold for $795.
The history of home keyboards lies in mechanical musical instrument keyboards, electrified keyboards and 1960s and 1970s synthesizer technologies.
The OPL series are a family of sound chips developed by Yamaha. The OPL series are low-cost sound chips providing FM synthesis for use in computing, music and video game applications.
