The Yamaha S90 is a "stage piano" and music synthesizer hybrid, combining a high-quality, weighted 88-key piano action with the extensive sound engine of Yamaha's professional MOTIF synthesizer series. It is designed for musicians who require a premium piano feel and sound for live performance, but also need the flexibility and versatility of a synthesizer for studio work.
Key features
Premium piano sound: A primary selling point is the acoustic piano sound, which is based on high-quality stereo samples from a Yamaha concert grand piano (the S6 for the S90 XS and S700 for the S90 ES). The weighted Balanced Hammer Effect keyboard action provides an authentic and expressive playing experience.
MOTIF sound engine: The S90 shares its comprehensive sound library with the flagship MOTIF series, offering a vast array of instruments, synth tones, and drum kits. This gives players a complete sonic palette for any musical style.
Intuitive live performance controls: The S90 is built for the stage, with dedicated sliders, knobs, and buttons for real-time control over voices, layers, and splits. The "Performance Creator" feature allows for quick setup of complex, layered sounds.
Flexible DAW integration: The keyboard functions as both a master MIDI controller and a sound module for computer-based music production. The "DAW Remote" feature offers templates for controlling popular software like Cubase directly from the S90's panel.
Onboard recording: You can record your performances directly as audio files to an internal flash memory or an external USB flash drive. Some models also include a microphone/guitar input with dedicated effects.
Arpeggiator: An advanced, interactive arpeggiator with thousands of patterns and musical phrases allows for instant musical inspiration, including realistic guitar strumming and drum grooves.
