Korg Grandstage 73

The 73-Key, Korg Grandstage73 stage piano & master controller combines the acoustic piano tradition with the flexibility of an electronic instrument to deliver versatile on-stage playability. It offers a rich variation of sounds, an intuitive user interface on the front panel, and a keyboard with RH3 weighted hammer action, which directly conveys the delicate nuances and emotions of the player’s performance.

The Grandstage features seven sound engines with five grand pianos, an upright piano, six vintage electric pianos, three vintage organs, an analog synth, and an FM synth, for a total of 500 sounds. Straightforward operation lets the player concentrate completely on his/her performance. The sounds are separated into a Keyboard section and an Ensemble section and can be quickly selected or recalled from 64 Favorite locations. All effects and controls are quickly accessed using the front-panel knobs and buttons.

To help shape articulation and expressivity during a performance, the Dynamics knob instantly changes the way the keyboard’s dynamics (velocity) affects the volume and tone of your sound. The company’s proprietary Smooth Sound Transition (SST) function ensures seamless and natural switching between sounds or effects.

Made in Japan by dedicated and experienced craftsmen, the Korg Grandstage’s design echoes that of an acoustic piano. The instrument includes a dedicated music stand and a damper pedal.
