12 diatonic Accordions In One

Performing accordionists can cover all bases onstage with this one instrument. No matter the song, you can switch instantly between different tonalities and configurations of the keyboard/bass buttons. Diatonic musicians won’t have to carry a truckload of accordions onstage anymore! In addition to its amazing collection of virtual accordions, the FR-18 diatonic has other great instruments onboard, all instantly selectable. Choose from orchestral and brass instruments, exotic world instruments, percussion, organs, and more. The User Sets let you load your custom layouts of sounds and settings for instant recall.

Dedicated Acoustic and Orchestral Sounds for Each Set

The FR-18 diatonic comes with eight treble orchestra, three orchestra bass and three orchestra chord sounds that are different for each set. This means that each set (Folk, Classic, Tradition, Organetto and so on) will recall dedicated orchestral sounds relevant to that set. Three user sets allow the musician to customise the FR-18 diatonic with new acoustic and orchestral sounds. Dual mode function allows the accordionist to layer orchestral and accordion sounds for the right hand, so as to extend the melody part.

Tablature Sets

The FR-18 diatonic comes with a dozen instantly selectable tablatures, making it possible to cover numerous genres without ever having to change accordions! In addition, you can create your own tablatures with a PC/Mac software app (available via free download). With this software, the FR-18 diatonic is truly an open instrument with customizable layouts for the keyboard and bass buttons. Thanks to USB compatibility, it’s easy to transmit and receive custom tablature sets between computer and accordion.

Performance Style & Comfort

The speaker-less, lightweight body makes the FR-18 diatonic a comfort to wear and play. The long-life battery compatibility lets you roam onstage, free of unnecessary cables and clutter. The classic black finish blends well into any environment; it looks cool and stylish onstage yet elegant in the classiest of settings. In addition, there are exchangeable inlay sheets that let you change the appearance of the instrument. You can also create your own custom-designed inlay sheets and install them easily.

Private or Public

High-quality Roland earphones are included with the FR-18 diatonic package so you can play the instrument right out of the box. Practice at any hour without disturbing neighbors or surrounding environments. When it’s time to blast, however, plug the FR-18 diatonic into one of Roland’s award-winning amplifiers, such as the SA-300 stage amplifier.
