Get Top-Grade Professional Quality From The Korg Grandstage 73 Key Stage Piano

Korg's acclaimed flagship piano sound engine and meticulously selected keyboard sounds. Looks that pay respect to acoustic pianos, yet also convey the ingenuity and individuality of electronic instruments. And a panel layout that is carefully designed to draw out the player's personality and expression. Firmly grounded in both newness and in the piano tradition, it's the birth of a masterpiece for a new generation.

SGX-2: Six Acoustic Pianos

Containing piano sounds from top-level instruments worldwide, the SGX-2 acoustic piano sound engine is what makes the Grandstage worthy of the term "ultimate." The five grand piano sounds have all been lavishly captured using instruments from Berlin, Heidelberg, Austria, Japan, as well as a newly sampled Italian grand piano. These grand pianos are considered world-leading classics, and now they are available in an unparalleled playing experience. In addition, the Grandstage also provides a newly sampled upright piano sound, featuring an intimate character, different from its grand piano sounds, and possessing its own refinement and depth.

EP-1: Six Vintage Electric Pianos

The EP-1 electric piano sound engine contains a total of six vintage electric piano sounds: the classic I, II, V, and DMP tine piano models, and the 200 and 200A reed piano models. MDS (Multi-Dimensional Synthesis) technology delivers a further evolution of the concept of velocity switching, smoothly responding even to subtle changes in your keyboard dynamics. Realistically-reproduced amps, cabinets, speakers, and vintage effects add the finishing touches to these impeccable simulations.

CX-3, Vox, And Compact: Three Organs With Classic Personality

Three different organ sound engines are provided. The CX-3 tonewheel organ sound engine is a complete reproduction of KORG's classic combo organ that went on sale in 1980. The newly designed VOX transistor organ sound engine reproduces the sound of the VOX organ that went on sale in 1960's and had a massive impact on popular music in Europe and the US. Also new is the Compact transistor organ sound engine which simulates the compact organs that earned a legendary place in rock during the same years as the VOX organ. By using these sound engines with the rotary speaker effect that's built into each one.

RH3 Keyboard Responds To Your Every Nuance

Both 88-key and 73-key models of the Grandstage feature the Real Weighted Hammer Action 3 (RH3) keybed. Made in Japan, we are proud of the Premium Japanese Quality achieved through the careful production skills of a small number of dedicated and experienced craftsmen. Like the keyboard of a grand piano, it's divided into four regions in which the lower register feels heavier and the upper register feels lighter, beautifully conveying the delicate touch and nuances of your fingertips, and letting you experience a realistic playing feel.
