Roland V-Accordion FR-4XB RD

Power and Portability: The V-Accordion Revolution Continues

There’s plenty to love about the traditional accordion, from its expression to its portability. But if you’ve ever wondered where Roland’s acclaimed range of digital V-Accordions could take your performances, the new Roland FR-4XB RD (Red) is your chance to find out. With its light and compact design, responsive pressure-sensing bellows, and full-range onboard speakers, this latest model feels as familiar as your favorite acoustic accordion. But with the same powerful sound engine as Roland’s flagship FR-8x, this digital accordion goes even further. Choose from a wide selection of accordion sounds from around the world, and play in silence using headphones or connect to a PA for live performance. Control other electronic musical instruments via the MIDI connector, or record your playing to a connected USB stick and share your music with the world. While its sounds and playing feel are reassuringly traditional, the Roland FR-4XB RD is an accordion for the modern age.
