Excitement, Exhilaration, Applause 
A Stage Piano Masterpiece

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. 

KORG's Grandstage delivers the ultimate playing experience to make your on-stage performance captivating.

 

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. 

These SGX-2 sound engines contain high-capacity unlooped stereo samples for every key, and use up to 12 levels of velocity switching to perfectly convey the detailed and powerful expressiveness of an acoustic piano, extending to damper resonance that reproduces the spaciousness felt when the pedal is pressed, and even mechanical noise. 

Responding to the requests of numerous professional players, the Grandstage also provides monaural piano sounds for all of these acoustic piano programs. These monaural piano sounds were voiced not from a mono mix of stereo samples but from monaurally recorded sources, and will shine clearly even within a band's mix.

 

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, Grandstage provides a realistic and rewarding organ playing experience.

 

AL-1 and HD-1: 
A rich variety of sounds

The Grandstage comes stock with a total of 500 different sound programs, and in addition to the above five types of sound engine, it also gives you the AL-1 analog modeling sound engine that delivers well-defined reeds and thick brass sounds, and the HD-1 PCM sound engine that covers a bountiful variety of sounds. In particular, the HD-1 contains many new samples of distinctive keyboard instruments, including an eight-level multisampled clavi sound, as well as harpsichord, mellotron, pipe organ, and the distinctive metallic sound of an FM piano.
