Korg Grandstage X 88-Key Stage Piano

The Korg Grandstage X 88-Key Stage Piano is a flagship performance keyboard with seven sound engines, 700 preloaded sounds, RH3 weighted hammer action, and a redesigned stage-focused interface. It gives pianists and keyboardists expressive acoustic piano, electric piano, organ, synth, and PCM sounds in one premium instrument.

Designed for touring performers, worship teams, studios, and serious players, the Grandstage X makes it easy to buy an 88-key stage piano for live performance, build layered keyboard sounds, or perform with realistic piano feel. Dedicated split, layer, unison, rhythm, reverb, delay, and EQ controls keep core adjustments within quick reach.

Korg builds the Grandstage X around Japanese-crafted RH3 keys, premium sound engines, balanced XLR outputs, MIDI, USB, SD card storage, and flexible pedal inputs. Nutube-powered Analog Tone adds tube-style warmth, while the included music stand and DS-1H damper pedal support professional stage and studio setups.
