The Roland RD-300NX: Flagship Features at a Nice Price

Roland raised the stage-piano bar with the RD-700NX. Today, the world-famous SuperNATURAL® sound and expression of the flagship RD is available at a lighter weight and more affordable price: introducing the RD-300NX. This state-of-the-art stage piano boasts an advanced SuperNATURAL Piano sound engine, E. Piano sounds based on SuperNATURAL technology, a newly developed Ivory Feel-G keyboard with Escapement, a unique Sound Focus feature, and more.

SuperNATURAL® Sound
The RD-300NX’s acoustic-piano sounds are derived from Roland’s acclaimed SuperNATURAL Piano sound engine. With SuperNATURAL Piano technology, three essential elements are dramatically improved — velocity response, note decay, and key-range behavior — resulting in smooth, natural sound and response. For EP lovers, the RD-300NX contains an E. Piano based on SuperNATURAL technology that meticulously models classic vintage EPs.

New Ivory Feel-G Keyboard
The newly developed Ivory Feel-G keyboard incorporates Roland’s most advanced sensor, escapement mechanism, and Ivory Feel features. The keyboard provides the superior touch and sensitivity of Roland’s flagship keyboards, in a compact and lightweight design…a great benefit for gigging musicians who want to travel light.

Unique Sound Focus
The innovative Sound Focus feature ensures that every note will be heard, even subtle pianissimo passages. Based on SuperNATURAL phase-correction technology, this essential feature ensures that the RD-300NX won’t get lost in the mix, penetrating through walls of sound without compressing or coloring the tone. Players can relax and play naturally, achieving presence onstage without sacrificing dynamics and sound quality.

Bonus Features
The popular One Touch Piano concept from previous RD-series pianos has been carried over the RD-300NX as well. The handy feature provides instant access to essential piano and E. Piano sounds and setups with dedicated one-touch buttons. In addition, the popular and powerful Piano Designer feature has been included in the RD-300NX feature set, letting you build custom pianos quickly and easily on the graphic LCD.
