Yamaha 61-Key Entry-Level Arranger Workstation

With its white cone speakers and professional black finish, the PSR-S550B looks as good as it sounds. The PSR-S550 inherits the high-quality sound features of the PSR-S700/S900 to the max, resulting in improved musical performance through increased polyphony and more voices variations. Using the 16-track sequencer and Style Creator, the ability to produce a wide array of music has greatly increased.
