Music in Expansion

The V-Accordion is the first instrument of its kind to provide powerful digital modelling technology in a traditional, immediately familiar, accordion design, and with performance functions and authentic sounds.It combines the familiar sounds and nuances of a traditional accordion with the versatility of a modern digital musical instrument.The FR-7xb is the successor to the current FR-7b. It is enhanced with the latest V-Accordion features.

Fast response and high sensitivity

Thanks to Roland’s newly-developed sound generator, which is optimized for Accordion performance, the FR-7xb will satisfy the most demanding accordion players. You will be impressed by the fast response of the keys/buttons, the higher sensitivity and precision, and the detection of bellows opening/closing with new bellows pressure-sensor circuitry. Thanks to this new technology, accordionists can feel perfectly at ease when playing their music, especially once they have experienced the enhanced response of this instrument.

USB host port onboard

Easy data storage, handy customization of V-Accordion sound-sets to satisfy special accordion/orchestra demands from different countries, and easy to upload software versions, thanks to the USB Flash Memory. What’s more, you can manage MP3 and Wav files and even record your performances in Wav format on the optional USB Flash Memory. Playback and record functions are perfect for educational use, and enhance live performance too.

Battery-powered instrument with built-in speakers

Though the FR-7xb is a fully digital instrument, it’s also an all-in-one instrument, i.e. you do not need to connect it to any amplifier to produce sounds. Its onboard amplification system is powerful enough for small venues, restaurants, pubs. Furthermore, the FR-7xb comes with a rechargeable battery, so that you do not need to connect it to a power outlet. It goes far beyond the control possibilities of a MIDI keyboard with optional performance functions.

Super realistic accordion simulations…

The FR-7xb has 92 buttons with six Treble Modes (with velocity), 120 velocity-sensitive bass buttons (6 bass & chord modes and 5 free bass modes to suit your playing style) and can simulate up to 80 different accordion instruments each including 14 treble registers, 26 orchestral sounds, 7 bass & chord registers, 7 free bass registers, 7 orchestral free bass, 7 orchestral bass registers, and 7 orchestral chord registers. Thanks to the Bass to Treble mode the FR-7xb can be used like a “Basoon accordion.” In this mode the bass part is played with the right hand (the bass and chord buttons are inactive). Moreover the programmable Drum function allows you to play percussion sounds with the Bass & Chord buttons.

…and organ simulations

Thanks to the Virtual ToneWheel sound engine, the FR-7xb allows you to play amazing organ sounds, by using Treble (upper), Chord (lower) and Bass (pedal) sections. Harmonic Bar controls will allow you to personalize your organ sounds to satisfy every musical genre.

Easy combination of Orchestral and traditional accordion sounds

Traditional accordion and orchestral sounds can be easily combined and played with full bellows articulation. Several unique Orchestra modes (Solo, Dual, High/Low,and more)provide amazing flexibility and instant sound switching. The 26 onboard orchestral treble, 7 orchestral bass sounds, 7 orchestral chord sounds and 7 orchestral free bass sounds can be easily mixed with traditional sounds.

Other features

LCD Display: FR-7xb is provided with a easy to read LCD display (OLED type, 128x64) for setting easily your V-Accordion. USER assignable switches: you can now assign different functions to the 6 switches located in the last row of bass buttons.
