Roland is proud to announce the EXR-46 Oriental Arranger-Roland's most authentic and versatile Oriental-themed keyboard. As the newest addition to Roland's arranger-keyboard family, the EXR-46 OR retains many of the popular design characteristics of its predecessor (EXR-40 OR), but improves and builds upon the fundamental elements: sounds, styles, and Music Assistant features.
