V-Accordions have revolutionized the world of music, and Roland continues to focus on the development of these amazing instruments. The FR-1x series is the latest accordion in the renowned V-Accordion family. These compact and lightweight models offer the same flexibility and portability as their popular predecessors, the FR-1 and FR-1b, while introducing new features and capabilities, such as a USB port and new bellows sensors with improved sensitivity and accuracy. A significant advantage is the built-in sound system and display (7 segments/3 characters). Two types of keyboards are again available: keyboard and button.
