The Seven Functional Blocks
The S90 XS/S70 XS system consists of seven main functional blocks: Tone Generator, A/D Input, Sequencer, Arpeggio,
Controller, Effect, and Audio Record/Playback.
AWM2 (Advanced Wave Memory 2)
This instrument is equipped with an AWM2 tone generator block. AWM2 (Advanced Wave Memory 2) is a
synthesis system based on sampled waves (sound material), and is used in many Yamaha synthesizers. For extra
realism, each AWM2 Voice uses multiple samples of a real instrument’s waveform. Furthermore, a wide variety of
parameters—envelope generator, filter, modulation, and others—can be applied.
