Korg I3 MS

A Korg Arranger Designed for Immediate Inspiration and Mobility

With the I3, Korg focuses on the essentials that make a modern arranger keyboard powerful: ready-to-play sounds, effective accompaniments, and simple controls to stay focused on the music. The "Sound Sets" and "Style Performance Sets" intelligently combine sounds, styles, and settings to chain ideas without wasting time in menus. The result: an accessible, intuitive workstation especially suitable for mobile musicians, singer-songwriters, and event hosts.

Keyboard Design

The Korg I3 is built around a standard-sized 61-key keyboard with velocity sensitivity, ideal for alternating left-hand accompaniment, right-hand melody, and layered texture playing. To match your touch, you have 4 response curves (Soft, Medium, Hard, Fixed): useful for switching from delicate piano playing to a more aggressive pop/rock attack. The Octave Shift (+/-2) controls extend the range with a single gesture, while the joystick manages pitch, modulation, and brightness for natural expressiveness. A 2-band global equalizer (bass/treble) allows immediate sound balance adjustment depending on the room, amplification, or headphones.

Sound Quality

The Korg I3's stereo PCM generator delivers a versatile sound base with 790 sounds (including a full GM2 set) and 59 drum kits, all with a 64-voice polyphony to maintain solid chord and layering integrity. The 200 "Sound Sets" facilitate access to ready-to-play configurations, with up to 4 keyboard parts (layer/split) to stack a piano and strings, separate a bass on the left, or build more modern combinations. A dedicated "Grand Piano" button instantly recalls the main piano sound, ideal when you need to return to a reliable tone between songs.

Built-in Effects

• 2 multi-effects for the keyboard section + 2 multi-effects for accompaniment, with 173 variations in total.
• Effect families suited for live and production: reverbs, chorus/ensemble, delays, modulations, rotary, overdrive, compressor, and equalization.
• 2-band global equalizer (bass/treble) for quick correction depending on the venue, PA system, or headphones.
