The Korg Grandstage X represents a complete redesign of Korg's flagship stage piano, offering musicians an inspiring performance instrument that excels both sonically and visually. With its elegant two-toned light ivory and black color scheme, angled control panel, flat top, aluminum body, and distinctive perforated metal side panels, the Grandstage X makes a striking visual statement whether on stage or in the studio.

At its core, the Grandstage X delivers exceptional sound quality through seven powerful sound engines. The SGX-2 engine powers 13 acoustic pianos, including the new GSX Piano and familiar favorites from Korg's impressive catalog like the Nautilus, Oasys, and SG1D pianos. For those seeking vintage sounds, the classic M1 Piano from the '80s is also included.

Electric piano enthusiasts will appreciate the EP-1 engine with seven authentic electric piano voices covering all the essential vintage tones. Organists haven't been forgotten, with three dedicated organ engines: CX-3 (Tonewheel), Vox (Transistor), and FC-1 (Transistor). The AL-1 analog modeling engine handles synthesizer sounds, while the HD-1 PCM module rounds out the comprehensive sound palette.

Designed with performing musicians in mind, the interface prioritizes intuitive operation. Players can easily layer and split sounds with dedicated buttons, while individual level controls for each part allow for perfect balance. The keyboard features Korg's responsive RH3 weighted hammer action, and the innovative key-touch slider provides instant control over volume and timbre changes with each keystroke.

Sound processing is equally impressive, with Nutube-powered analog-style effects, a 3-band EQ, and multiple delays and reverbs. The Grandstage X even includes rhythm and chord progression functions to create complementary backing tracks that follow your playing.

With 700 preloaded sounds, 100 favorite slots (including 20 preloads), and approximately 25.5 GB of PCM storage capacity, the Grandstage X offers extensive sonic possibilities in a professional package that weighs 25 kg (55.12 lbs). Expected to arrive in June, the Korg Grandstage X promises to be a serious contender in the premium stage piano market.
