DX-21
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 by Yamaha. 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. Keyboard The keyboard has 61 keys which are not velocity-sensitive to harder or softer key presses. It can produce eight note polyphony, which means up to eight keys can be pressed at once. In split keyboard mode, the polyphony limit is still eight notes, but there is a maximum of four for the lower half and four for the upper half. In mono mode, the DX21 can play only one note, unless the k ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yamaha Corporation
is a Japanese multinational musical instrument and audio equipment manufacturer. It is one of the constituents of Nikkei 225 and is the world's largest musical instrument manufacturing company. The former motorcycle division was established in 1955 as Yamaha Motor Co., Ltd., which started as an affiliated company but has been spun-off as its own independent company. History was established in 1887 as a reed organ manufacturer by Torakusu Yamaha () in Hamamatsu, Shizuoka Prefecture, and was incorporated on 12 October 1897. In 1900, the company manufactured the first piano to be made in Japan, and its first grand piano two years later. In 1987, 100 years after the first reed organ built by Yamaha, the company was renamed Yamaha Corporation in honor of its founder. The company's origins as a musical instrument manufacturer are still reflected today in the group's logo—a trio of interlocking tuning forks. After World War II, company president Genichi Kawakami repur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yamaha YM2164
The Yamaha YM2164, a.k.a. OPP (FM Operator Type P), is an FM synthesis sound chip developed by Yamaha, an enhanced version of their YM2151 (a.k.a. OPM). The OPP was used in various MIDI-based synthesizers by Yamaha - DX21, DX27, DX100, SFG-05, FB-01 (a standalone SFG-05) - plus several licensed products: the IBM Music Feature Card (which is effectively an FB-01 on an ISA card) and Korg's DS-8 and Korg 707. The YM2164 has the following features: *Eight concurrent FM synthesis channels (voices) that may all be set to different timbres *Four operators per channel, all generating sine waves at configurable frequencies and powers *Eight options for routing those four operators to perform FM synthesis (via phase modulation) or simple additive synthesis *A low frequency oscillator running 1 of 4 waveforms, mappable to pitch on a per-channel basis and/or amplitude on a per-operator basis Compared to the OPM, the OPP has the same pinout and functional features but some minor c ...

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 the early 1980s, the synthesizer market was dominated by analog synthesizers. Frequency modulation synthesis, a means of generating sounds via frequency modulation (FM), 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 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, ''Billboard'' Hot 100. Its electric pian ...

Yamaha DX100 (synthesizer)
The Yamaha DX100 is an FM synthesis, FM synthesizer released by Yamaha Corporation, Yamaha in 1986. It offers four operators for each of its eight voices, and has eight algorithms (compared to the Yamaha DX7, DX7's six operators for each of its sixteen voices, and thirty-two algorithms). It has only 49 mini-keys, and no arpeggiator or effects, but is still useful, known in particular for its bass patch #1. It features up to 192 presets, seriously improving the DX7's limited preset capabilities. It can also store 24 user-programmable sounds in RAM. It lacks cartridge support, but voice patches can be saved to and loaded from an external Cassette tape, cassette recorder. It was the cheapest user-programmable FM synthesiser made in the 1980s, leading to its popularity even amongst professional musicians in the 80s and 90s. It's essentially a cut down version of the Yamaha DX21, DX21 and Yamaha DX27, DX27, using the same FM chip, the Yamaha YM2164, YM2164. See also * Yamaha DX1 * Y ...

Envelope (music)
In sound and music, an envelope describes how a sound changes over time. For example, a piano key, when struck and held, creates a near-immediate initial sound which gradually decreases in volume to zero. An envelope may relate to elements such as amplitude (volume), frequency (with the use of filters) or pitch. Envelope generators, which allow users to control the different stages of a sound, are common features of synthesizers, samplers, and other electronic musical instruments. The most common envelope generator is controlled with four parameters: attack, decay, sustain and release (ADSR). Envelope generators Development The envelope generator was created by the American engineer Robert Moog, the creator of the Moog synthesizer, in the 1960s. The composer Herbert Deutsch suggested Moog find a way to articulate his synthesizer so notes did not simply trigger on and off. Moog wired a doorbell button to the synthesizer and used a capacitor to store and slowly release ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Low Frequency Oscillator
Low-frequency oscillation (LFO) is an electronic frequency that is usually below 20 Hz and creates a rhythmic pulse or sweep. This is used to modulate musical equipment such as synthesizers to create audio effects such as vibrato, tremolo and phasing. History Low-frequency oscillation was introduced with modular synthesizers of the 1960s, such as the Moog synthesizer. Often the LFO effect was accidental, as there were myriad configurations that could be "patched" by the synth operator. LFOs have since appeared in some form on almost every synthesizer. More recently other electronic musical instruments, such as samplers and software synthesizers, have included LFOs to increase their sound alteration capabilities. Overview The primary oscillator circuits of a synthesizer are used to create the audio signals. An LFO is a secondary oscillator that operates at a significantly lower frequency than other oscillators, typically below 20 Hz — that is, below the range of h ...

Chorus Effect
Chorus is an audio effect that occurs when individual sounds with approximately the same time, and very similar pitches, converge. While similar sounds coming from multiple sources can occur naturally, as in the case of a choir or string orchestra, it can also be simulated using an electronic effects unit or signal processing device. When the effect is produced successfully, none of the constituent sounds are perceived as being out of tune. It is characteristic of sounds with a rich, shimmering quality that would be absent if the sound came from a single source. The shimmer occurs because of beating. The effect is more apparent when listening to sounds that sustain for longer periods of time. The chorus effect is especially easy to hear when listening to a choir or string ensemble. A choir has multiple people singing each part (alto, tenor, etc.). A string ensemble has multiple violinists and possibly multiples of other stringed instruments. Acoustically created Although ...

Comping (jazz)
In jazz, comping (an abbreviation of accompaniment; or possibly from the verb, to "complement") is the jazz harmony, chords, rhythms, and countermelody, countermelodies that keyboard players (piano or organ), guitar players, or drummers use to support a musician's musical improvisation, improvised solo (music), solo or melody lines. It is also the action of accompanying, and the left-hand part of a solo pianist.Hughes, Fred (2002). ''The Jazz Pianist: Left Hand Voicings and Chord Theory'', p.5. . Types In a standard jazz combo, the pianist or guitarist typically comps during the horn section, horn and double bass solos by improvising chord (music), chords and counter-melody, countermelodies. The chordal accompaniment used in jazz is different from the chordal accompaniment style used in many types of popular music, such as rock and folk. *In a rock or folk band, a guitarist or piano player will accompany by playing primarily root-position triad (music), triads consisting of the ...

Keyboard Amplifier
A keyboard amplifier is a powered instrument amplifier, electronic amplifier and loudspeaker in a speaker enclosure, speaker cabinet used for the amplification of electronic keyboard instruments. Keyboard amplifiers are distinct from other types of Instrument amplifier, amplification systems such as guitar amplifiers due to the particular challenges associated with making keyboards sound louder on stage; namely, to provide solid subwoofer, low-frequency sound reproduction for the deep basslines that keyboards can play ''and'' crisp high-frequency sound for the high-register notes. Another difference between keyboard amplifiers and guitar/bass amplifiers is that keyboard amps are usually designed with a relatively flat frequency response and low distortion (music), distortion. In contrast, many guitar and bass amp designers purposely make their amplifiers modify the frequency response, typically to "roll-off" very high frequencies, and most rock and blues guitar amps, and since th ...

Yamaha YM2151
The Yamaha YM2151, also known as OPM (FM Operator Type-M) is an eight-channel, four-operator sound chip developed by Yamaha. It was Yamaha's first single-chip FM synthesis implementation, being created originally for some of the Yamaha DX series of keyboards ( DX21, DX27, and DX100). Yamaha also used it in some of their budget-priced electric pianos, such as the YPR-7, -8, and -9. Uses The YM2151 was used in many arcade game system boards, starting with Atari's System arcade boards in 1984 (of which its first game ''Marble Madness'' was released on), then Sega arcade system boards from 1985, and then arcade games from Konami, Capcom, Data East, Irem, and Namco, as well as Williams pinball machines, with its heaviest use in the mid-to-late 1980s. It was also used in Sharp's X1 and X68000 home computers. The Commander X16 8-bit hobbyist computer also contains a YM2151 chip onboard for sound generation. The chip was used in the Yamaha SFG-01 and SFG-05 FM Sound Synthesizer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motorola 6800
The 6800 ("''sixty-eight hundred''") is an 8-bit microprocessor designed and first manufactured by Motorola in 1974. The MC6800 microprocessor was part of the M6800 Microcomputer System (later dubbed ''68xx'') that also included serial and parallel interface ICs, RAM, ROM and other support chips. A significant design feature was that the M6800 family of ICs required only a single five-volt power supply at a time when most other microprocessors required three voltages. The M6800 Microcomputer System was announced in March 1974 and was in full production by the end of that year. "Motorola's M6800 microcomputer system, which can operate from a single 5-volt supply, is moving out of the sampling stage and into full production." The small-quantity price of the MC6800 is . The MC6820 PIA cost . American Microsystems was licensed as the second source. The 6800 has a 16-bit address bus that can directly access of memory and an 8-bit bi-directional data bus.
