An electronic musical instrument or electrophone is a musical instrument that produces sound using electronic circuitry. Such an instrument sounds by outputting an electrical, electronic or digital audio signal that ultimately is plugged into a power amplifier which drives a loudspeaker, creating the sound heard by the performer and listener.
An electronic keyboard, portable keyboard, or digital keyboard is an electronic musical instrument, an electronic derivative of keyboard instruments. Electronic keyboards include synthesizers, digital pianos, stage pianos, electronic organs and digital audio workstations. In technical terms, an electronic keyboard is a synthesizer with a low-wattage power amplifier and small loudspeakers.
Novation Digital Music Systems Ltd. is a British musical equipment manufacturer, founded in 1992 by Ian Jannaway and Mark Thompson as Novation Electronic Music Systems. Today the company specializes in MIDI controllers with and without keyboards, both analog and virtual analog performance synthesizers, grid-based performance controllers, and audio interfaces. At present, Novation products are primarily manufactured in China.
The Yamaha AN1x is a DSP-based analog modeling synthesizer, produced by Yamaha Corporation from 1997 to 1998, and was marketed as an "analog physical modelling control synthesizer".
The Roland Jupiter-4 (JP-4) was an analog synthesizer manufactured by the Roland Corporation between 1978 and 1981. It was notable as the company's first self-contained polyphonic synthesizer, and for employing digital control of analog circuits, allowing for such features as programmable memory, voice assignment modes, an arpeggiator, polyphonic portamento and others.
The Yamaha TX81Z is a rack version of Yamaha DX11 and rack-mounted (keyboard-less) frequency modulation music synthesizer, which was released in 1987. 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. A keyboard version with more onboard editing abilities was released the following year as the Yamaha DX11.
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.
Polyphony is a property of musical instruments that means that they can play multiple independent melody lines simultaneously. Instruments featuring polyphony are said to be polyphonic. Instruments that are not capable of polyphony are monophonic or paraphonic.
The Korg Wavestation is a vector synthesis synthesizer first produced in the early 1990s and later re-released as a software synthesizer in 2004. Its primary innovation was Wave Sequencing, a method of multi-timbral sound generation in which different PCM waveform data are played successively, resulting in continuously evolving sounds. The Wavestation's "Advanced Vector Synthesis" sound architecture resembled early vector synths such as the Sequential Circuits Prophet VS.
The Yamaha SY85 is a digital music workstation introduced in 1992. Unlike other Yamaha synthesizers of the time the SY85 does not use FM synthesis. Instead, its sounds are based on samples, which can be layered and modified to create new sounds.
The Roland XP-80 is a music workstation that uses digital PCM subtractive synthesis and combines an updated version of the JV-1080 synthesizer engine with the sequencer capabilities of the Roland MRC-Pro sequencer. The XP-80 was introduced in 1996 and is now discontinued.
Roland JX-8P is a 61-key, velocity- and aftertouch-sensitive, six-note polyphonic, fully analog synthesizer released by Roland in 1985. In a time of rising popularity of digital frequency modulation synthesizers, such as Yamaha DX7, JX-8P was marketed as the best of both worlds: while it was possible to create classic analog synth sounds, several new modulation parameters and redesigned hardware enabled it to produce certain types of sounds associated with FM synthesis, such as metallic percussive sounds. Likewise, traditional hands-on controls were replaced with a DX-style interface with membrane buttons and one "edit" slider.
Yamaha SY77 is a 16 voice multitimbral music workstation first produced by Yamaha Corporation in 1989. The SY77 is a synthesizer whose architecture combines AFM synthesis, AWM2 for ROM-borne sample-based synthesis, and the combination of these two methods christened Realtime Convolution and Modulation Synthesis (RCM). The same technology was also packaged in a rack-mounted module released simultaneously, the TG77.
The Yamaha FS1R is a sound synthesizer module, manufactured by the Yamaha Corporation from 1998 to 2000. Based on Formant synthesis, it also has FM synthesis capabilities similar to the DX range. Its editing involves 2,000+ parameters in any one 'performance', prompting the creation of a number of third party freeware programming applications. These applications provide the tools needed to program the synth which were missing when it was in production by Yamaha. The synth was discontinued after two years, probably in part due to its complexity, poor front-panel controls, brief manual and limited polyphony.
A synthesizer is an electronic musical instrument that generates audio signals. Synthesizers typically create sounds by generating waveforms through methods including subtractive synthesis, additive synthesis and frequency modulation synthesis. These sounds may be altered by components such as filters, which cut or boost frequencies; envelopes, which control articulation, or how notes begin and end; and low-frequency oscillators, which modulate parameters such as pitch, volume, or filter characteristics affecting timbre. Synthesizers are typically played with keyboards or controlled by sequencers, software or other instruments, and may be synchronized to other equipment via MIDI.
Casio's SDSynthesizers were a late-1980s line of analog synthesizers featuring a resonant filter. SD synthesis was traditional DCO-analog synthesis, with the main difference being that some of the SD waveforms' harmonic spectrums changed temporally, or dynamically in relation to the amplitude envelope. SD synthesis is used in six Casio synthesizers and home keyboards released in 1987 and produced until 1991, when Casio exited the synthesizer market completely and focused solely on pure consumer keyboards. Due to some programming limitations plus Casio's poor marketing, the SD synths never gained wide popularity and are now fairly rare in the second-hand marketplace. There still exists a small but devoted fanbase who insist that SD synthesis, particularly as expanded in the high-end model HT-6000, was overlooked and highly underrated and today really rare
The Yamaha Music SynthesizerS90 is a synthesizer and a MIDI controller in one unit, released in 2002 to supersede the S80. As such, it is part of the S series together with the S03 and S08. It was superseded by the S90ES in 2005, itself superseded by the S90XS in 2009.
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 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.
