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 performance, the new Roland FR-4xb 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-8xb, 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 is an accordion for the modern age.

If you play a traditional accordion, you won’t want to compromise on the expressive feel and portable format. You don’t have to with the Roland FR-4xb, which plays like a great acoustic accordion and travels light. The intuitive layout of 92 right-hand and 120 left-hand buttons feels instantly familiar, while the pressure-sensing bellows circuitry lets you tailor the inertia to your preference. This new digital accordion might feature lots of onboard technology, but its light and compact design—plus the option of powering from an AC adaptor or AA batteries—make it a great choice for players on the move.
Jam with Your Favorite Songs, or Record Your Own
The USB memory port is your pathway to some of the Roland FR-4xb’s most useful features. By inserting a USB stick preloaded with your favorite songs or your band’s latest material, you can jam along with the music as it plays back and perfect your parts at your convenience. If you want to get creative, the FR-4xb also features a handy onboard recorder; simply record a new part, save it to a USB stick, and then transfer your creation to a computer and share it with the world. USB export also allows you to safely archive your customized sound settings.
Flexible Outputs for a Variety of Music-Making Scenarios
Practice. Rehearsal. Studio. Stage. The Roland FR-4xb has the flexibility to support you wherever you’re making music. The headphones jack lets you practice at home without disturbing the neighbors, and when you’re on the go, a powerful onboard audio system with two speakers and a tweeter supplies big, full-range sound. Ambitious music makers can even connect with external MIDI devices like the Roland BK-7m Backing Module for controllable accompaniment. Gigging accordion players will appreciate that the FR-4xb is fully stage-ready, providing a direct connection to a venue’s PA system via the Line Out and sparing the headaches of trying to mic up a traditional accordion.
