The SGX-2 grand piano engine from KRONOS and NAUTILUS

Loop-free stereo samples for all 88 keys
To appreciate the incredible depth and quality of the sounds in each of the 5 piano engines of KORG Collection SGX-2, start by playing single low notes to hear how the sound naturally decays without any looping. Next, try playing chords while holding down the damper pedal. The chord resonance and stereo spread remain natural and beautifully balanced, with each note decaying as it should - just as it does on a real piano.
The SGX-2 uses loop-free stereo samples for every key, allowing you to enjoy the piano’s inherently natural sound.With up to 12 velocity layers, every subtle shift in your touch brings the sound to life – enabling nuanced, expressive performances with complete control over tone and dynamics.

Includes 5 Piano Models
KORG Collection SGX-2 includes five meticulously sampled pianos, chosen from the finest instruments found in concert halls and studios around the world:
• German Grand – deep, balanced, and majestic
• Japanese Grand – bright, powerful, and articulate
• Italian Grand – rich, lyrical, and expressive
• Japanese Small Grand – intimate and detailed
• Japanese Upright – informal and full of character
Each model responds with lifelike nuance, allowing you to choose the perfect piano for any style or mood — from cinematic scoring to intimate solo performances.

String Resonance, Damper Resonance, and Una Corda
Real pianos sing with sympathetic resonance — when one string vibrates, others subtly respond. With the damper pedal raised, only held notes and the higher octaves resonate together. Press the pedal and every note joins in, producing a rich, enveloping resonance. The SGX-2 captures this complex acoustic behavior in every detail, faithfully recreating the natural resonances that occur both with and without the pedal. The result is a piano tone that breathes, shimmers, and feels unmistakably alive.
Grand pianos have an additional "soft" pedal, technically known as una corda — Italian for “one string.” Normally, each hammer strikes two or three strings at once. When you press the una corda pedal, the keyboard and hammer mechanism shift slightly to the right, causing the hammer to hit one fewer string and producing a softer, more delicate tone. The Italian Grand model includes true una corda support, faithfully capturing these subtle shifts in volume and timbre, so you can perform with the full expressive range and authentic pedal response of a real piano.
Equipped with a Variety of Effects
The SGX-2 goes beyond simple acoustic piano tones with a full arsenal of studio-quality effects. Sculpt your sound with three flexible insert slots and a dedicated reverb. The 35 effect types span from vintage choruses, flangers, and phasers to lush tape echoes, reverse delays, and immersive shimmer reverbs.
