Yamaha PSR-SX900 Arranger Workstation

Official Page

Overview

The Yamaha PSR-SX900 is a flagship arranger workstation that combines an enormous library of realistic instrument voices and professionally arranged accompaniment styles with powerful performance features, making it one of the most capable one-person-band keyboards available. The sound engine features Yamaha's Super Articulation 2 voices that reproduce the subtle nuances and playing techniques of real instruments, from guitar string slides to brass growls, creating accompaniments that sound remarkably lifelike. The style engine offers hundreds of professionally programmed accompaniment patterns spanning every genre from jazz and Latin to EDM and world music, each with multiple variations, fills, and intros. The sixty-one-key organ-style keyboard is velocity sensitive and ideal for melody playing and chord triggering. An integrated vocal harmony processor adds harmonies to a connected microphone, enabling solo performers to sound like a full ensemble. The seven-inch color touchscreen provides intuitive navigation through the vast sound and style library. Audio playback and recording capabilities allow integration with backing tracks and live performance recording. Expansion packs add genre-specific content. The PSR-SX900 is ideal for solo entertainers, wedding musicians, and hobbyists who want a complete musical accompaniment system in a portable keyboard. The organ-style keybed does not provide the weighted feel that pianists accustomed to acoustic instruments prefer.

The PSR-SX900 represents the pinnacle of Yamaha's mid-tier arranger line, effectively acting as a 'Genos Junior' for performers who need professional firepower without the flagship price tag. The transition to the FSB keyboard action is a noticeable improvement, offering a firmer resistance and better initial touch than its predecessors, though it still lacks the premium feel of a weighted hammer action.

Sonically, the Super Articulation 2 voices are the highlight, delivering stunningly realistic woodwinds and strings that respond dynamically to your phrasing. The inclusion of the Chord Looper is a game-changer for live performers, allowing you to free up your left hand for lead synth work or physical controller manipulation. The 7-inch color touchscreen finally brings the PSR line into the modern era, drastically reducing the menu-diving that plagued older models.

However, the chassis remains primarily plastic, which feels a bit lightweight given the investment. While the internal bi-amped speakers are surprisingly punchy for home use, serious gigging musicians will still find themselves reaching for the sub-outs. For songwriters and solo entertainers, the SX900 hits a sweet spot of functionality and portability. It's a sophisticated tool for those who need complex arrangements on the fly, though the sheer depth of the OS might be overkill for hobbyists.
