TheYamaha YS200 is anFM synthesiser and workstation produced byYamaha, introduced in 1988. It combines a sequencer, rhythm machine, an FM synthesissoundchip and aMIDI keyboard. It was called theEOS YS200 in Japan and was also released as a more home-oriented keyboard in the form of theYamaha EOS B200, which also featured built-in stereo speakers. The YS200 is the keyboard equivalent of theYamaha TQ5 module. The forerunner of the YS200 was the almost-identical[citation needed]Yamaha YS100.

Thefrequency modulation synthesis provided by the YS/TQ sound engine is very similar to many other 4-op synths released by Yamaha during the 1980s. The YS/TQ is nearly fully compatible - aside from lackingportamento - with voices andsysex for the earlierDX11,DX21,DX27,DX100, andTX81Z. The synthesis unit has an 8-note polyphony and 8-instrument multitimbral capability.
The synthesis itself is based on 4 operators (each being anoscillator plus anenvelope generator), which could be chained in various combinations by selecting one of the 8 available algorithms. Each operator can generate one of 8 selectable waveforms. Additionally, in each of the algorithms, operator 4 can be set to modulate itself with a configurable amount of feedback. The sound-producing unit is the same of theYamaha TX81Z module, namely theYamaha YM2414 soundchip.
The YS/TQ units contain 100 preset voices stored on ROM and an additional 100 user-configurable sounds in RAM. Voices can be assigned to up to 8 Instruments, which in turn can be layered into configurations called Performances, thus providing more interesting sounds than one voice could alone. One common way to use this feature is to include several instances of the same voice in the same performance while detuning each of them slightly to create a "thicker" or more lively sound.
The engine also provides a number of effects, including reverb, delay, and distortion.
The YS200's keyboard consists of 61 keys, covering 5 octaves. It supports both velocity sensitivity and monophonic aftertouch. The MIDI transmit channel of the keyboard is configurable. Wheels for pitch bend and modulation control are provided on the left side of the keys.
The internal sequencer has 8 tracks, with an approximate capability of 16000 notes shared between maximum of 8 songs at a time. Songs are stored in RAM and can also be saved to or loaded from an optional MCD memory card inserted into the built-in slot.
The Yamaha YS100 was the previous YSsynthesizer released byYamaha, the only differences with the YS200 are that the YS100 lacks the built-in sequencer and aftertouch.
