The Roland RD-700SX is an 88-key professional stage piano that was introduced in 2005. It added Roland’s enhanced **SuperNATURAL-based piano engine** for more expressive acoustic piano sounds, building on the RD-700. In addition to improved electric piano tones and two SRX expansion slots for adding more sounds, it keeps the Progressive Hammer-Action keyboard. It offers a wide range of effects, versatile MIDI control, and strong connectivity for professional use, all with an emphasis on performance.
