Back by Popular Demand

First released in 1984, Korg's RK-100 set keyboardists free from their old-school static rigs. For the first time, keyboard players could roam the stage and play solos alongside guitarists and singers around the world. Now, the groundbreaking keytar is reborn as the RK-100S! This 37-key keytar is equipped with 37 velocity-sensitive keys, an 8-note polyphonic synthesizer with two oscillators, dual ribbon controllers, and 200 presets that fit any genre and playing style. Setup is easy, simply connect headphones or an instrument cable, and you're ready to rip solos like a guitarist. The RK-100S is USB and MIDI-enabled for use as a master synth in the studio. Combining good looks and ergonomic design with incredibly versatile tones, the RK-100S is a must-have for keyboardists of all kinds.

200 stage-ready presets

The RK-100S gets its signature sound from Korg's MMT (Multiple Modeling Technology) sound engine. This keytar's MMT is an 8-note polyphonic synth with 2 oscillators and a built-in noise generator that can create an expansive amount of tones. The keytar ships to your door with 200 stage-ready presets that cover all genres and playing styles. An included 6-program arpeggiator provides a diverse range of patterns. For quick access to your most-used presets, just hit the favorites button on the top panel.

Slim keyboard with dual ribbon controllers

Here at Sweetwater, we're impressed by how comfortable the RK-100S is to play. This is thanks to the 37-note slim keyboard that helps keep the keytar sleek and compact. It's also loaded with a pair of ribbon controllers to increase your performance options. The short ribbon located on the neck controls the pitch bend and modulation. The long ribbon located at the top of the key bed can be used to control the pitch or the filter. Together, they enable bold and smooth expression. The RK-100S showcases uncompromising playability and expressive features to fit your playing style.

Useful for the studio as well as the stage

It's undeniable that the Korg RK-100S is great for the stage. However, this keytar is more than meets the eye. It has a MIDI output and USB port that allow it to control a soft synth or an external hardware module. It's not just limited to the 200 presets either. Just plug it into your computer and use the PC editor to download detailed settings for MIDI and the internal sound engine. You'll find that the extra control is perfect for use in the studio.

Ergonomic body design helps you play in total comfort

The RK-100S rebels against the traditional constraints placed on keyboards. It takes more than a few design cues from the electric guitar, including the slim neck and contoured body. The keytar has a lightweight wooden body that feels perfectly balanced on your shoulders. A helpful leg rest is carved into the body to make it easy to play while sitting down. Add in eight-hour battery life, and you have total freedom to roam around the stage.

Included software bundle

The RK-100S comes with a diverse selection of music software to take your recordings to the next level. This bundle includes great music production and learning software such as, Ozone Elements, Skoove, Reason Lite, and many more! Once you unbox your Korg RK-100S, you'll have a variety of tools at your disposal for musical creation.

Glad KORG brought this one back

Missed the boat on the last one. Glad the RK 100s2 is back and better than ever. Had to get a replacement midi remote for my roland ax 1. The RK fits the bill ! ! !
Rated 5/5

Really nice to look at, listen to, and take to the stage!

Worth the wait on this one. Korg got it right with the S2 version of the RK. Nothing on the market has this quality of build. The stained wood is sooooo nice. Love that it's a microKorg XL+ on the inside. Lots of cool control include two ribbons for neat note and filter tricks.

Looking for a standout keytar, look no further.

Oh, and the slim keys are not that big of a deal. I got comfy with them in about 20 minutes. Really cuts down on weight and size!

This thing is a lot of fun!

Synth sounds are ok, others not so much...BUT, this thing is so much fun. I have only used it at home and at a few rehearsals to amuse my band mates. They beg me to bring it to the shows because it's just a fun instrument. I use batteries and a wireless system to get mobile and it's a blast.
Rated 5/5

Great synth and controller with style!

This instrument was worth the wait. I've played a lot of different keytars, and I really appreciate the Rk's features and feel.

The 37 slimmer keys were really easy to adapt to, and that cuts down on the size of the product which I like very much. It's a solid piece; I believe the only keytar on the market that has a wood body. the synth engine is the same as Korg's micro Korg Xl plus which is a great 8-voice engine. For me, playing solos and chords, it's more than plenty. Rich analog modeling. The scaling and arp features add a nice zing to performances as well!
