A Modern Heir to the RD Lineage
Iconic on stages since 1986, the RD series has shaped the standard for stage pianos. The "RD-88 EX" condenses this heritage into a portable format while expanding the sonic palette thanks to the SuperNATURAL/ZEN-Core duo, recallable scenes, and integrated speakers. For RD-88 owners, an "RD-88 EX Upgrade" is available via Roland Cloud to align their instrument with this edition.Keyboard Design
The "RD-88 EX" features a PHA-4 Standard 88-key hammer action keyboard with escapement and Ivory Feel, offering high-resolution velocity sensitivity. The touch combines precise attack and fine control of dynamics, from pianissimo to fortissimo, while maintaining a manageable weight for transport and stage setup.Sound Quality
The dual sound architecture blends SuperNATURAL (expressive acoustic and electric pianos) and ZEN-Core (organs, strings, brass, synths, and more, totaling over 3,000 timbres). The 400 scenes allow chaining complete configurations for live performance. The 128-voice polyphony ensures dense textures without note dropouts, while the 2x6 W system (12 cm + 2 cm) delivers clear and full sound for daily practice and small venues.Built-in Effects
- Multi-effects per zone (3 systems, 90 types), zone EQ, "Tone Color" control
- Stage IFX (90 types), sympathetic resonance
- Chorus/Delay (8 types), Reverb (6 types)
- Master Compressor and Master EQ, plus dedicated Reverb/EQ for inputs
