Kronos X 73 Music Workstation

   (0 reviews)

A peerless synthesizer packed with nine sound engines --- including realistic piano, richly expressive electric piano, tonewheel organ, digital synthesis, and powerful analog/physical modeling -- all in a single unit. The KRONOS X Music Workstation is the single instrument designed for live performing musicians; for artists creating music in a studio or computer-based production environment; and for musicians and sound designers seeking the ultimate synthesizer. In creating KRONOS X, we have listened to many musicians and have heard their requests. And KRONOS X delivers.

LIVE - for the performing keyboard player New sound engines KRONOS X provides the absolute finest in keyboard sounds; accurate and responsive to the player's technique. The expansive control surface offers joysticks, sliders, knobs, switches, a ribbon controller, assignable pedal inputs, and of course our high-resolution color TouchView™ display. Performance-oriented additions include our easy-to-use Set List mode for song-specific and gig-ready sound selection, and our Smooth Sound Transition feature. Plus, we've included our finest RH3 keybed on both the 73 and 88 key models for a solid performance experience; the 61 key enjoys the responsive action shared with the Korg M3-61.

User Sample Banks let you create your own high-capacity sample libraries. User Sample Banks bring the benefits of KORG’s EXs to your own custom sample libraries. You can load and play many gigabytes of your custom or converted samples at once, using the internal SSD. Disk and memory management is also improved: you can create subsets of User Sample Banks, and mix and match parts of different banks, without duplicating samples on disk. It’s also easy to share sounds with friends and collaborators, since Programs, Wave Sequences, and Drum Kits maintain links to User Sample Banks even when samples are moved on disk or loaded onto a different KRONOS instrument. Create your own samples, or import Akai and SoundFont 2.0 libraries using new, improved conversion features.

In order to take full advantage of these nine sound engines, KORG called on respected musicians to guide our sound design team towards their individual ideals. Responding positively, numerous world-class players contributed their time, energy, and critical listening to help us zero in on making the sound respond the way they hear it! Certain artist signature sounds were tested, judged and tweaked by the likes of Herbie Hancock, Jordan Rudess, Frank McComb, George Duke, Lyle Mays, Russ Ferrante, Tom Coster, John Novello, Ricky Lawson and several other artists known for their serious love of sound and for their critical, demanding ears.

KORG’s Rock-Solid Workstation Integration Puts it all Together
KARMA, Drum Track, Sampling, Ring, Audio Recording, MIDI Sequencer...
Packed with unlimited sound potential, KRONOS X is much more than a synthesizer. KRONOS X comes complete with all of the extras required of a modern workstation, plus so much more. From music production to live performance, the KRONOS X Music Workstation integrates a world-class list of tools into a single, reliable instrument. Under the hood, all nine engines share the same hardware, with no separate cards to manage or polyphony barriers between them—and no “CPU overs” to worry about. KRONOS X dynamically allocates power between the engines as you play, automatically and in real time, providing an integrated experience that no PC can match. In addition, KRONOS X smoothly functions as a plug-in with many popular DAWs, providing your studio with native, unprecedented sonic power.


First appearing on KORG’s Karma Music Workstation in 2001, this revolutionary algorithmic music technology instantly produces sophisticated phrases, drum grooves and full-blown backing tracks. Based on the notes and chords you play and the intuitive operations you perform with the knobs, sliders, and switches, you’ll easily produce musical effects that exceed anything you imagined.
Now in its greatly-enhanced second generation, offering features like KARMA Wave-Sequencing, Note Mapping and 8 scenes per layer, KARMA is standard equipment on your new KRONOS X. It will expand your conception of a song, and will be an enormous asset to your live performances.

Drum Tracks

KRONOS X also borrows the Drum Track feature from the M3 and M50 Music Workstations. Drum Tracks can create everything from a simple reference beat to an outline rhythm track all the way up to a full-blown drum track for your music productions. KRONOS X now includes professional drum performances from artists such as Ricky Lawson, which are able to generate grooves reproducing the distinctive feel of a pro drummer. Applications and extras have been generously poured into this single feature. The Drum Track can go well beyond rhythm machines, and is fully capable of standing on its own.

Open Sampling System

No matter whether you're in Program, Combination, or Sequencer mode, you can always use KRONOS X to sample an external audio source, or to resample the performance of the KRONOS X itself. User samples can be edited using operations such as truncate, normalize, time stretch, or time slice. Edited samples can also be exported in AIFF or WAVE format.

You can also load external samples in AIFF, WAVE, SoundFont 2.0, and AKAI S1000/3000 formats via USB memory. By loading samples that you've previously created on other instruments or on a PC, you can set up your music production system on the KRONOS X –with no additional equipment required.

16-track MIDI sequencer / 16-track audio recorder

KRONOS X features a sequencer/recording section that offers both 16 MIDI tracks plus 16 audio tracks; a great resource for putting together a dazzling performance or a brilliant production. MIDI sequencing makes it easy to capture ideas, inspiration, and pro-quality phrases using the KARMA, Drum Track, or RPPR (Realtime Pattern Play/Recording) functions. The 16-track audio recorder simultaneously captures up to four tracks of 16-bit/24-bit uncompressed data at a sampling rate of 48 kHz. Play along with recorded tracks, add effects, and then resample the KRONOS X itself and place the resampled WAVE files directly in a track.

When polishing your tracks, feel free to use mixer automation and editing functions like copy, paste, and normalize to get the results you want. Plug in a USB CD-burner and assemble your album right from the TouchView display!

Premium-quality effects suite – use up to 16 effects simultaneously


KRONOS X provides 16 internal effects to add impact to your sonic creations. Each of the 12 Insert effects can be applied to individual or multiple timbres in a combination, or to individual or multiple tracks of the sequencer. In addition, two Master effects can be applied to sends 1/2, and two Total effects can be applied to all tracks at the final stage of the sound. Each effect offers 185 distinct effect types, covering every possible sound-shaping need. Examples include a high-resolution reverb, chorus, delay, guitar amp and cabinet modeling, and even vocoding. Each effect provides up to 72 adjustable parameters, as well as numerous real-time modulation possibilities, delivering outstanding versatility.
A separate three-band EQ is provided for every timbre, for every sequencer track, and for every audio track for adjusting subtle tonal balances or for creatively modifying the overall sound.

Set List

In creating KRONOS X, we listened to many musicians from around the world. Our goal was to change the way musicians interacted with their instrument to provide a more fluid, expressive, and natural experience.
At one level, this meant providing a comprehensive yet intuitive control surface. But with KRONOS X, we wanted to take these ideas even further, creating an instrument ideally suited to the way musicians play.
Smooth Sound Transition eliminates dropouts when changing sounds


KRONOS X features our Smooth Sound Transition technology. This powerful addition is designed to maintain any currently held, played, or sustaining notes (with their effects), helping to prevent drop-outs from occurring when you switch sounds or change from Program mode to Combi mode.
A high level of technology has been applied to finally bring this sought-after ability to reality, fulfilling the requests of many musicians.

Enhanced, color TouchView display

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.

KRONOS Editor and Plug-In Editor* KRONOS X is supported by the KRONOS Editor and Plug-In Editor*, which let you edit and organize sounds from a Mac OS X or Windows computer. Plug-in operation allows you to save settings as part of your project with any VST-compatible Windows software, or any VST- or AU-compatible software on Mac OS X.

You can create backup files on your computer, send sample data at high speed from your computer to the KRONOS X, and use your computer to manage data that's on the KRONOS X’s internal disk. By enhancing the integration with your computer it’s now even easier to get your musical projects completed.

The KRONOS X provides a total of six channels of audio input: 2 analog channels, 2 digital channels (S/P DIF optical, 48 kHz/24-bit), and 2 USB channels. As audio outputs, you have the 2 main channels (L/MONO, R) as well as four independent audio outputs, 2 digital channels (S/P DIF optical, 48 kHz/24-bit), and 2 USB channels (note: the 2 digital channels and 2 USB channels output the same signal as the main L/R output). All analog inputs and outputs support TRS balanced connections. The analog inputs provide a MIC/LINE select switch and an independent level control for each channel, offering the flexibility to meet any situation.

In addition to the type-B USB connector used for communicating with your computer, there are two type-A USB 2.0 ports for use with external storage media such as flash memory, hard drives, or CD-R/RW and DVD drives. The output of the KRONOS X can be resampled to a USB storage device such as a hard drive, or connected to USB CD-R/RW drive to create audio CDs.
