More beautiful than ever.
The long-awaited rebirth of KORG's famous keytar.
Since its appearance, the RK-100S keytar has been a hit for its uniquely ergonomic styling, powerful sound engine, and standout looks. Now by popular demand, the RK-100S returns in a big way.
The artisanal wooden body inherited from the original RK-100 is a hallmark of the 100S, which is now available in a finish that accentuates its wood grain. Numerous sounds ideal for solo performance have been added, making the RK-100S fit instantly into any musician’s stage performance.
The RK-100S returns.
Clear finish that beautifully shows the woodgrain
The greatest attraction of the RK series is its beautiful body shape that refuses to be bound by the constraints of keyboard instruments. The wooden body is strongly influenced by guitars, featuring a design that includes both strength and softness to generate an enduringly ageless attractiveness.
The RK-100S 2 further progresses this attention to detail, and features a clear finish that lets the woodgrain show. Since each individual unit will have a different woodgrain (*), it projects an even greater sense of high quality and taste than previously. Although it is an electronic instrument, each individual unit is finished with careful attention, making it an instrument with a distinctively unique presence that will continue to provide the joy of ownership.
* Since the body of this instrument uses natural wood, please be aware that there will be individual differences in the woodgrain and appearance.
Newly featured programs that shine with presence for soloing
The renewed RK-100S 2 significantly expands the built-in programs. In particular, we have strengthened its complement of lead synth sounds and other solo sounds that let the musician shine. We have added many of the latest sounds frequently heard in today's music scene, providing 200 stage-ready presets to cover all genres. The sounds emitted from this compact body are supremely powerful, and these sounds can be instantly accessed during a live performance by using the favorite buttons on the top panel. Also provided is an arpeggiator with a diverse range of patterns.
37-note slim keyboard that's easy to play
Both looks and keyboard feature an understated design that will feel comfortable for any player. The RK-100S uses an acclaimed 37-note slim keyboard. While keeping the overall size compact and lightweight, we have focused on making this mini-keyboard uncompromisingly "playable."
Two ribbon controllers expand your performance possibilities
The RK-100S is designed for your aggressive performance style. It features two ribbon controllers that you can use to dynamically modify the sound.
Battery operation with long operating life
The RK-100S can be powered by six AA batteries. Simply connect headphones to the instrument, or use a cable to connect it to an amp, and you're ready to start playing just like a guitarist. Since up to eight hours of continuous operation are possible, you can concentrate on your performance without having to bother with power cables on stage. Of course, you can also use a separately sold AC adapter if you like.
Vocoder function adds an accent to your stage performances
The monaural mini-input jack accommodates mic input, so you can connect a headset mic and enjoy full-fledged vocoder playing. You can also connect a smartphone etc. as an external source input, and have fun playing along with a favorite song.
A great choice as a master keyboard
The RK-100S is not limited to playing its preset sounds. It is equipped with a MIDI output connector and USB port, so you can also use it to play a soft synth or an external hardware sound module. Furthermore, its elegant looks make it a great choice as a master keyboard.
You can also use the PC editor to download detailed settings for MIDI and the internal sound engine from the Korg website via USB.
Use the PC editor for detailed editing
The RK-100S 2 has a USB port for connecting it to your computer, allowing you to control a PC sound module or use the PC editor to edit detailed MIDI settings and parameters of the internal sound engine.

In other words, the moment you get your hands on this keyboard you'll have a variety of tools to help you take your music to the next level.
The short ribbon provided on the neck area lets you control the pitch bend and modulation that are indispensable for keyboard performance. The long ribbon located on the keyboard area can be used to control the pitch or filter. You can use this to create bold and smooth sweeps for sustained sounds. Furthermore, it supports scale performance in which notes can be sounded simply by touching the ribbon, giving you free scope for unconventional performances that would not be possible with standard keyboard playing.
