The Rebirth of KORG's Famous KeytarSince its first 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.
Features
• New programs that emanate powerful presence when soloing
• 37-note slim keyboard for easy playability
• Two ribbon controllers to broaden your performance potential
• Vocoder function lets you accent your staging
• Battery operation allows long operation time
• Great choice as a master keyboard
• Includes soft case and strap
Newly featured programs that shine with presence for soloing
The renewed RK-100S 2 significantly expands the built-in programs. In particular, KORG strengthened the lead synth sounds and other solo sounds that let the musician shine. It includes 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.
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.
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.
Free bundle of music software
The RK-100S 2 comes with a diverse variety of music software from Izotope including "Ozone Elements" which lets you not only create songs but also master them using AI, "Skoove" which will help you improve your keyboard playing skills, "Reason Lite" DAW software, as well as software synths from KORG and other brands.

Sturdy & we repurchase yearly for Hubby’s refresh
Color: Brown (Rodeo)
This is my hubbys tried and true wallet. He requests this same one every year as a refresh. He wears his 24/7 in his back pocket so it gets discolored but still holds its shape pretty well with a slight bend.

Great for everyday wear, vibrant dial, comfy band, no locking crowns. Would buy again.
Color: 6638: Gold band & Green dial
Excellent price point, stylish, and the pictures match what you get. The green is bright and vibrant and the gold band looks real although stainless. A great piece to wear all the time without worrying about losing value. Would buy again. My biggest complaint: The small crown do not lock so they get randomly hit and cant be trusted. The time kept is fine but do no expect to be able to lock the days in. The crown wont spin to lock them.

Looks really good.
Color: 6638: Gold band & Gold dial
Looks great, quality is really good too. Only downfall is that if you don't wear it everyday, you will have to wind it up and move it to get the second hand moving again and then set the time again i can get mine sit for a whole day without resetting time but by day two it has to be reset. Even with that, it's a great watch. Have gotten lots of compliments.
