Korg GS1-88 Grandstage

Sound engines that deliver the utmost in stage sound perfection. The Grandstage is equipped with seven powerful sound engines that make it the ultimate stage piano.

The Grandstage provides carefully considered parameters and a thoughtful panel layout with numerous highly usable functions to ensure that you'll achieve your best performance whether you're playing live or in a session.

Grandstage brings the player unprecedented expressive power. The Dynamics knob is KORG's new feature that is unique to the Grandstage. It instantly changes the way in which your keyboard playing dynamics (velocity) affects the volume and tone, allowing you to customize the playing feel of the keyboard in real time to suit your performing style or the genre of music.

Turning the dynamics knob toward the left provides a softer sound with a wider dynamic range in response to your keystrokes. This allows more sensitive expression since the sound responds directly to changes in your playing strength; ideal for piano solos or when playing accompaniment. Conversely, turning the dynamics knob toward the right provides louder sound relative to your playing strength, creating flatter dynamics. This is ideal when you want to play with a consistent touch so that your sound will stand out in the band or ensemble.

The favorites buttons let you register up to 64 of your favorite sounds. If you've saved your settings for a live performance, the sounds you need can be instantly recalled during a song or between songs. The sounds you save can be registered as a combination of the keyboard section and ensemble section.

KORG's unique "Smooth Sound Transition" (SST) function creates smooth and natural change when you switch between sounds and effects even while you perform; it's been further refined on the Grandstage.

The Grandstage is equipped with a three-band equalizer that lets you adjust the character of the overall sound appropriately for the acoustics of your live performance venue. It can be controlled easily just by operating the faders.

Just by turning on the two sections "keyboard" and "ensemble," you can play layers or splits using the two programs selected for each section. Layer/split selection, split point settings, and swapping the lower and upper can all be accomplished easily using the panel switch, with no need to delve into the depths of a menu.

The panel lock prevents sounds or settings from being unintentionally changed. You won't need to worry that your hands might accidentally come in contact with a knob or button while you're absorbed in your performance on stage.

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.

The Grandstage features an elegant design that exemplifies the elegance of an acoustic piano, the very quintessence of keyboard instruments. Its front panel features hairline-finished aluminum, and striking red LEDs ensure great visibility even on a dimly lit stage. The rear panel features chic woodgrain, creating an individualist and stylish appearance that will be obvious at a glance. The entire rear panel KORG logo can be brightly illuminated, and you can adjust the color, brightness, and illumination mode to your taste. As a piano that was born for the stage, this instrument makes a statement.

The Grandstage comes with a dedicated music stand that can be attached to the instrument, a damper pedal (DS-1H) that supports half-pedaling, and ships including a newly designed keyboard stand (Standard-M-SV) with a sophisticated chrome plated finish to match the instrument. A complete stage piano system based on the Grandstage will elevate your performance to the ultimate.
