Main Features

The Korg Grandstage is a stage piano that was designed in the
pursuit of onstage playability, offering a rich variation of sounds
including the greatest acoustic and electric piano sounds, along
with an intuitive user interface.
The greatest piano sounds
• The Grandstage includes five of the world's most famous
grand piano sounds. An SGX-2 dedicated acoustic piano
sound generator makes both delicate and powerful, richly
expressive sounds a reality with large, non-looping waveform
samples in full stereo sound across the keyboard.
• The Grandstage includes vintage electric piano sounds from
six classic models. The EP-1 dedicated electric piano sound
generator makes the best sound a reality, with natural changes
in sound and delicately-modeled panel effects, cabinets and so
on.
Rich variation of sounds
• The Grandstage offers 500 types of sounds separated into
two sections, KEYBOARDS and ENSEMBLE. Selecting
a category and variation within each section allows you to
choose your sound and play right away. The names of sounds
are shown on an easy-to-read organic EL (electro-luminescent)
display.
• Within the KEYBOARDS section, you can select grand piano,
upright piano, electric piano, clav, and organ sounds. Within
the ENSEMBLE section, you can select sound commonly
used in stage performance such as strings, brass, synthesizer,
and bells.
• The Grandstage features seven high-quality sound synthesis
engines, including the SGX-2 (acoustic piano), EP-1 (electric
piano), CX-3 (tonewheel organ), VOX organ, compact electric
organ, AL-1 (analog modeling), and the HD-1 (PCM sound
generator).
• A powerful effects section is provided. The optimum effect for
each sound is already preset, such the standard assortment of
effects like phaser and chorus for electric piano. Also, on the
REVERB/DELAY section, reverb and delay can be instantly
set.
• Layer and split functions can be set instantly. This is used to
stack two sounds together, or to play two different sounds on
the left and right of the keyboard.
The pursuit of onstage playability
• FAVORITE buttons are located at the center of the front panel.
These 16 buttons can be combined to register 64 types of
sounds or settings. These sounds and settings can be recalled
instantly while playing live.
• The DYNAMICS knob can be used to instantly change how
the volume and sound responds to changes in touch (i.e., how
hard or soft the keys are played). The performance feel can be
customized to match the playing style required (such as solos,
ensembles, and bands) and the song. The EQUALIZER sec-
tion can be used to instantly change the characteristics of the
entire sound, to match the acoustics of the performance venue.
• A smooth sound transition (SST) feature eliminates dropouts
in sound when changing sounds, making it possible to switch
sound and effects naturally.
• The Grandstage uses an RH3 (Real weighted-Hammer action
3) keyboard. This keyboard recreates the feel of a grand piano,
letting you perform highly nuanced, delicate passages.
