The RK-100 is back by popular demand, reborn as the KORG RK-100S2 keytar. First released in 1984, the original KORG RK-100 enabled keyboardists to strap their instrument on like a guitar and explore the stage like never before. KORG updated the “keytar” in 2016 with the RK-100S, which eliminated the need for an external sound module with its built-in modeling sound generator. It was also more compact and lightweight with the addition of a slim keyboard. The 100S2 includes all the updates of the 100S but refines the structural design to improve its rigidity. Plus, the RK-100S2 features an artisanal wooden body with a finish that accentuates the gorgeous grain of the wood. Included with the RK-100S2 is a guitar-style strap, a dedicated soft case and more.

KORG RK-100S2 Main Features

  • Beautiful wood body and convenient battery operation
  • Newly featured programs, sounds, vocoder and more
  • 37-note slim keyboard and dual ribbon controllers
  • Use as a master keyboard to control external hardware

Contoured Wood Body and Convenient Battery Operation

Strongly influenced by the curves of electric guitars, the RK-100S2 features a beautifully shaped wooden body. Each unit is carefully finished with a clear coat that allows the elegant wood grain to shine through. You can use a separately sold AC adapter to power the RK-100S2. But, it can also run using six AA batteries. With up to eight hours of continuous use, you can concentrate on your stage performance without being tied down by power cables.

New Sounds, Arpeggiator and Vocoder

The RK-100S2 expands on its predecessors’ built-in programs, adding numerous lead synth sounds ideal for solo performance. KORG packed the RK-100S2 with 200 powerful, stage-ready presets covering a wide range of modern genres. These presets can be instantly accessed while performing by using the favorite buttons on the top panel. Plus, the onboard arpeggiator serves up a diverse range of patterns to work into your performance. The monaural mic input allows you to connect a headset mic for full-fledged vocoder playing. You can also connect your smartphone or other playback device and jam along with your favorite songs.

37-Note Slim Keyboard and Dual Ribbon Controllers

The RK-100S2 features KORG’s acclaimed 37-note slim keyboard. The design offers uncompromising playability while keeping the instrument light and compact. Adding to the 100S2’s performance capabilities is its two ribbon controllers, which you can use to create dynamic, bold sweeps and sustained sounds. The ribbon controller on the neck lets you control the pitch bend and modulation. The long ribbon on the keyboard area can be used to adjust the pitch or filter. They also support scale performance, where notes can be triggered simply by touching the ribbon.

A Great Choice as a Master Keyboard

The RK-100S2 is equipped with a MIDI output and USB connectivity. These allow you to use the RK-100S2 as a master keyboard. Use it to play a soft-synth or an external sound module. You can also use the PC editor via USB to download detailed MIDI settings and the internal sound engine from the KORG website.
