Over the years, Yamaha S-series synthesizers have set new standards for sound quality,
features and value. And with the new S90 Music Synthesizer, that tradition continues.
Developed to be our most feature-packed S-series synth to date, the S90 inherits the best features of the S-series line — plus the great sounds and user interface of our award-winning MOTIF synthesizer. In addition to superb piano action, a powerful arpeggiator and 24-bit effects, the S90 gives you 110MB* of wave samples — more than any other keyboard in its class. And as if that weren’t enough, we generously equipped it with three expansion slots for Modular Synthesis Plug-in System boards, so you can add new and exciting synthesis possibilities according to your musical needs.
