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

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.

Comfortable and stays cool
Color: White-cooling Basic, Size: Queen(Pack of 1)
Great pillow. When i opened it, i noticed a strange smell, i assumed its the smell of whatever they use to make the pillow stay cool. You have to fluff it for a good amount of time to make sure the cooling agent spreads well in the foam. Is what i assumed atleast. Its a perfect amount of softness for me. Pair it with some bamboo pillow cases and you got a good night of sleep

Comfortable and Supportive, but Adjust the Filling
Color: White-cooling Basic, Size: Queen(Pack of 2), Color: White-cooling Basic, Size: Queen(Pack of 2)
I’m very happy with this pillow. The size is big and it feels soft while still providing good support, perfect for midnight scrolling on TikTok.
One thing to keep in mind is that it can feel a little too tall if you use all of the filling that comes with it. The good news is that you can easily adjust the amount of filling to find the height that works best for your sleeping position. Once I customized it, it was much more comfortable.
Overall, great quality, comfortable, and worth the purchase.

BEST PILLOWS EVER!!!
Color: White-cooling Basic, Size: Queen(Pack of 2)
I am very picky with my pillows because I have a bad neck and I can never seem to find a good pillow. But I tried this pillow because it had everything I was looking for and the price was great! You get two of them and they are absolutely awesome.! normally I would need to lay on two pillows to try and get comfortable but with these pillows I just lay on one and I wake up with no neck pain. They really have a nice cooling effect. They actually puff up immediately after opening them. All you have to do is just shake them up and the pillow just puffs straight up.. It comes with extra cushioning if you want it to make it firmer and if you don’t want it as firm as it is, you can actually take some out. It really is such a beautiful pillow. It’s perfect in every way to me being such a picky pillow person.
You just lay your head down on it and it forms around your neck and your head and when you get up, it goes right back to its normal form. It doesn’t get flat and I love it. I completely recommend this to anyone who is a person who has a hard time finding a really good pillow.

Top of the line, best pillows Ive ever had
Color: White-cooling Basic, Size: Queen(Pack of 2)
These pillows are top of the line! I bought them in 2024 and they are still fluffy. When they lose a little fluff, you just punch em around a little bit and voila, like new again. They have kept their shape cery well and do great for cooling. I haven't had to add more filling yet either. I just laid my head on one and thought, I need to do a review cause everytime i lay on these pillows its like clouds. My head is heavy and this is relief :-D
