The i3 is packed with over 800 instruments, 200 sound sets, and 270 authentic musical styles, all created by a team of master programmers and musicians. An additional 59 custom drum kits and a complete MIDI GM2 sound set make the i3 a capable instrument. Calling up any of the 200 factory Sound Sets allows up to four sounds to be played at once: three layered across the upper keys, and one split to the lower keys. While Sound Sets are played in real time by the user, the 270 Style Sets contain various pre-programed drum, percussion and accompaniment parts to elevate your performance into a full sounding musical production. In order to achieve this full sound, there are up to eight parts that make up your backing tracks. A high-fidelity PCM sound engine and two stereo effects processors make the i3 capable of creating expressive music with motion and depth. A convenient Grand Piano button located on the main panel means you can instantly recall a beautiful acoustic piano sound at any time.

The KORG i3 inherits an easy-to-use arranger interface distilled from our renowned Pa series keyboards to help you put together ideas quickly and efficiently, making it easy to enhance any performance by adding in additional parts. Drumbeats, bass lines, percussion hits, and any other backing parts can be instantly selected or muted by pressing the convenient illuminated push buttons on the main panel. Style performance settings, sound set settings, tempo, effect settings, can all be saved into a single Set List location for instant recall. There are 10 banks of Set Lists, each with 5 locations to save your favorite configurations. Similar to our Pa Series, each Style includes four rhythmic variations, a count-in, a break, plus an intro and an ending. Active backing parts will follow your chord changes to create a personalized backing track to match your performance. If you need some harmonic inspiration, the eight Chord Buttons can trigger ready-made chords to keep your creative process moving forward. As you get more familiar with the i3, you can swap or substitute backing sounds, grooves and parts from any Style Performance Set, resulting in a truly custom sound. These features mean that each Style can be a complete song-creation environment, with ready-to-play sounds, parts, and chords.

The i3 Arranger features plenty of connections to satisfy any musical situation.
When not running on battery power, the i3 can be connected to an AC power source using the included adapter. There are two 1/4" outputs (Left/Mono and Right), and a useful 1/8” stereo headphone output jack that makes it easy to connect your favorite pair of headphones. An 1/8” audio input is also provided for easy play along functionality with your favorite tracks. A 1/4" foot controller jack is provided, with the function of the footswitch or expression pedal being defined in the settings of the i3. A MIDI output jack sends note and timing data from the i3 to other MIDI equipped instruments or audio gear. Two USB ports are provided, one that can save and load user data and songs to and from a USB flash drive, and the other to connect the i3 to a computer.
