Korg KRONOS X73 Keyboard 73-Key Synthesizer

The KRONOS music workstation was unveiled in 2011. Everyone who experiences its sound reacts with astonishment at how far electronic musical instruments have come --- followed, no doubt, by the thought "what can possibly follow this?!" But, in the year since its inception, KORG has continued to release system updates and additional KRONOS Sound Libraries, bringing the KRONOS to an even higher state of perfection. Rather than resting on its laurels in 2012, the KRONOS continued to evolve. Boosting its internal memory capacity and the size of its SSD, as well as enhancing its sampler functionality, we have included more of the latest technology in order to make the KRONOS the ultimate workstation. Fittingly, its new name adds an "X" to indicate its unknown potential. Ready to take off into the unknown future of sound we present the KRONOS X music workstation. 


  • A peerless synthesizer containing nine sound engines, including: realistic piano, richly expressive electric piano, tonewheel organ, digital synthesis, and powerful analog/physical modeling.

  • Approximately 2GB of available PCM RAM and a doubled SSD capacity of 62 GB allow support for gigantic sound library expansions, such as the KRONOS Sound Libraries and the KARO Sound Libraries.

  • The user Sample Bank feature allows users to create extremely large sample libraries that take advantage of the generous PCM RAM and SSD capacity.

  • Numerous artist signature sounds created by top musicians are included, letting you make the sounds of classic songs your very own.

  • KARMA, the Open Sampling System, and the on-board sequencer offers 16 MIDI tracks + 16 audio tracks

  • Use up to 16 premium-quality effects at once; individual effects rival dedicated units

  • Performance Power!

    Set List screen provides single-touch selection, regardless of mode

  • Smooth Sound Transition: this often-requested feature allows held or sustained notes to keep sounding when changing sounds or modes.

  • Support for USB MIDI and Korg USB pad controllers, including the Korg nano series and microKEY series

  • Support for the KRONOS Editor and Plug-in Editor software

  • USB Ethernet adapter compatibility enables high-speed data communication between the KRONOS X and your computer

  • Available with 61, 73 or 88 keys

    73 and 88 key models feature Korg’s finest RH3 Graded Hammer Action.

  • Comprehensive interface, based around a large 8” TFT TouchView™ display

The 88-key model of the KRONOS X features the same RH3 real weighted hammer action keyboard that's used on KORG's upper-end piano models and on the SV-1. The hammer weighting is graded, providing a heavier feel in the lower register and a lighter feel in the upper register, just as on a grand piano, offering superb playability. Boldly, the 73-key model also features this same RH3 keyboard, creating a more compact and transportable instrument that still provides superior piano and electric piano sounds teamed with an authentic piano touch. KRONOS X is notable for its slim design, showing an integration of function and design. 

KORG's TouchView graphical user interface is based on a large, color 8-inch (800 x 600 pixel) touch screen. The TouchView display is the centerpiece of KORG’s intuitive design, providing easy-to-view information and simple touch control. In developing KRONOS X, we also incorporated numerous images of actual instruments and their respective controls into the display, to ensure that the musician enjoys the feeling of playing an instrument – rather than controlling a machine. 

KRONOS X provides support for connecting USB MIDI class-compliant controllers directly to the KRONOS X. For instance, you can use a Korg microKEY as an auxiliary synth-action keyboard for a KRONOS X-73 or 88. Even better, KORG USB MIDI controllers with pads–including the nanoPAD, nanoPAD2, and padKONTROL–are automatically mapped to the KRONOS chord pads, for playing and programming drums, triggering chords, and selecting and assigning chords for Chord Mode.
