Kronos, Re-loaded

Since its introduction, Korg's Kronos has been the weapons-grade workstation of choice for keyboard A-listers such as Jordan Rudess and Derek Sherinian, as well as the no-compromise synth mavens here at Sweetwater. Now Korg ups the ante with the re-voiced and revamped Kronos. Under the hood of this beast, a new System 3.0 OS enhances functionality while juicing your workflow. The beefed-up SGX-2 piano engine boasts, in addition to its renowned German and Japanese grand pianos, a killer 9GB Berlin grand, as well as uber-expressive sympathetic resonance and una corda samples you can tweak to taste. Kronos also rocks sexy new visuals with a sleek aluminum body, mesh back panel, and lacquered wood end cheeks.

Korg Kronos 73-note Keyboard Workstation at a Glance:
  • Nine sound engines, infinite possibilities
  • Amazing new technologies for smoother, more expressive sounds
  • A studio of music-production gear onboard
  • Easy-to-use hands-on environment
Nine sound engines, infinite possibilities

From acoustic instruments to gritty analog synths, the nine synthesis engines onboard Korg's Kronos can provide every sound you need. The SGX-2 acoustic piano engine captures every nuance of real German and Japanese grand pianos, from damper resonance to mechanical noise. Then there's the EP-1 electric piano engine, which uses Multi-Dimension Synthesis to let you tweak, morph, and totally customize the wide range of classic electric piano sounds. These two synthesis engines are worth the price of admission alone - and they're just the beginning!

Amazing new technologies for smoother, more expressive sounds

The incredible sounds found in the Kronos simply wouldn't be possible without powerful new synthesis technologies. That's why Korg equipped this flexible workstation with components such as solid-state flash-based storage. The ultra-fast streaming possible with solid-state memory is the driving force behind Korg's Virtual Memory Technology, which provides you with high polyphony and incredible unlooped samples. It also allows the Kronos to perform smooth sound transitions, so you can hold sustain notes while switching sounds or modes - just what you need for seamless transitions.

A studio of music-production gear onboard

More than just an amazing performance keyboard, the Korg Kronos is a complete 32-track music-creation workstation. In addition to a robust 16-track sequencer, Korg gave Kronos the capacity to record up to 16 audio tracks as well - all in studio-standard 24-bit/48kHz quality! What's more, Kronos gives you an entire studio rack full of effects to enhance your music. You can run up to 16 fantastic effects at once, each of which more than rivals dedicated standalone effects units. And thanks to the Kronos's Open Sampling System, you can instantly sample and resample any sound you create, allowing you to come up with amazing new sounds.

Easy-to-use hands-on environment

Long known for their easy-to-use workstation environments, Korg raised the bar again by loading Kronos with hands-on controls. Starting with the large 8" TouchView display, you'll find navigating through the Kronos environment to be absolutely intuitive. Kronos also provides you with an entire dedicated control surface, complete with channel-strip-style sliders, knobs, and buttons. Plus, you get great performance controls, including a ribbon controller and one of Korg's fantastic vector joysticks. What's more, Kronos comes loaded with Korg's top-of-the-line KARMA technology, making it a truly impressive performance keyboard as well as a first-class keyboard workstation!

Korg Kronos 2

It's hard to describe the Korg Kronos 2 in just a few paragraphs. Imagine not one, but nine top quality synthesizers all packaged together. Now, connect them to a high quality keyboard with a really great action, weighted just enough to satisfy a pianist, but light enough to allow organists and synthesists to riff with relative ease. Blend this "computer" (that's truly what the Kronos is) with a 16 channel mixer, (complete with faders) allowing the keyboardist to layer pianos, organs, strings, guitars, and basses, with every conceivable orchestral instrument (many in preset groups), plus an amazing array of synthesizer tones and pads. It's a live performers dream! Add the ability to not only split and layer programs (up to 16 zones, overlapping if desired) but to assign 'velocity' to the various tones so that certain ones are only triggered when you strike the keys harder. There is a downloadable PDF manual for going deeper into the sounds, and deep is an understatement. For example, dozens of onboard effects are provided, each with numerous variables. Online tutorials make getting the basics down a breeze. Once you understand how to break down mixes or "combis" into their constituent parts, and how to store your edited sounds into memory, creating "lists" of tones (your own quick-access banks), you are off and running. I haven't even touched on KARMA, sequencing, the onboard 16 track recorder, the drum sets, the drum patterns, or the ability to pipe external audio, including live sampling (want to record your child's voice and make your own choir?) this is truly a remarkable keyboard! I also want to compliment the great people at Sweetwater, including my representative, Jim Watson and the CEO, Chuck Surack, for taking the extra time to answer my many questions, for going the extra mile in helping me put together the right accessories, and for helping me acquire a financing package that would work for me. As always, they made the whole experience great.

Kronos 2

OK, if you want a do everything keyboard with style and the best sounds possible then you've arrived at your new home base. Yes the Kronos can be a bit to take in during the first three or four month but after that things really start to come together. The more you learn about this fabulous machines data base and onboard sound library the more you'll love it. I got the 73 weighted key action and it's great for me. I had the Nord 5D 73 and it was an in creditable instrument in it's own right. But the Kronos comes extremely close to it's piano and organs but can go so much further. The only fault that I can lay at the feet of the Kronos is that their drum tracks are set too loud. Again with a little research I now know how to adjust them and make the overall experience soooooo much better. If you're considering this type of Keyboard drop the hammer, you won't be sorry.

Versatile, great for live performance

This replaced two keyboards in my live rig, which now consists of only the Kronos and a MIDI keyboard controller that plugs into it. The separate keyboard is for organ and synth leads, which are clumsy on the K73's weighted piano-style keybed. They call this a "workstation", which makes it sound as though its intended application is composing and recording. But it's actually a superb live instrument, due to the Set List feature and bright 8" color LCD display. No more futzing in the dark trying to bring up the right patch between songs. Brilliant.If your main instrument is piano, you'll love the Kronos for that. Lots of pianos to choose from, for any musical style from classical to classic rock. Samples are not looped and have between 8 and 12 velocity layers. The keyboard action is quite nice. OK, it's not a Steinway. But for a 40-lb piano alternative, it's quite nice.It's also a good lead synth. Strings and guitars are usable but not jaw-dropping. Pads and horns are good. BTW, I am basing my evaluations on Kontakt-based sample libraries and VSTi's, not on other ROMplers. Kronos' factory sound sets are as good as or at least comparable to anything from Roland or Yamaha, in every category.Organs are based on the CX-3 engine, which is OK, but without dedicated drawbars and switches it's not as ergonomic as a standalone organ. The Leslie sim is weak, so I use an external unit (Neo Instruments Ventilator) for that. And, as noted above, a separate light-action keyboard for playing organ.It's hard to think of many negatives. Add-on libraries are rather expensive (compared to Nord libraries, which are typically free downloads). It lacks traditional mod and pitch wheels (uses a joystick), which can be disconcerting if you've spent decades mastering those modulators for expressive playing. It takes more than 2 minutes to boot up (don't trip over the power cable during a gig!). At the time of this writing, there is no official carrying case for the K73 available in North America, and Sweetwater does not carry any generic cases that fit it well. I ultimately had one custom made, which was less-expensive and just the right size. This instrument is extraordinarily versatile. That can be a plus or a minus depending on your expectations. If you want a simple ROMpler for bread 'n butter sounds, there are less-expensive alternatives that might suit you better. Kronos' versatility necessarily means it's complex to navigate if you want to go beyond factory presets. It has 9 synth engines, and each one has its own unique UI to learn. Navigation can be confusing. Plan on spending some time studying the manual and watching videos. I've been at it for a month now and I'm just starting to feel comfortable in Kronos' O/S.Versatility extends to the hardware. You have no fewer than SIX audio outputs and two audio inputs. It can be used as an audio interface or an effects unit (150+ effects!). It has a 32-track sequencer (16 MIDI + 16 audio tracks). Three USB ports, and you can plug in an external display or laptop. External modulation sources are fully programmable, e.g. using an expression pedal for string swells while not affecting a piano in the foreground. Stack voices and route them to different destinations. Real surround if you want. No wall-wart (yay!), it has a proper internal power supply.Unlimited keyboard splits means you can program a patch for each song in your band's set list that includes every sound effect, every rhythm and lead voice you'll need in that song. Say you need a few sound effects, an organ and a synth lead - assign them to different ranges on the keyboard and eliminate the need for patch changes on the fly. If you can't fit everything into key splits, stack them and enable/disable/mix them as needed via the control surface (tip: choose "Live" mode in the Global settings for optimal polyphony and RAM usage).And yes, you can use it as a workstation, too. The built-in drum machine is OK for practicing, but I wouldn't use it for recording or live performance. The sequencer is easy to use but no substitute for a DAW. Polyphony is far greater than most digital keyboards, up to 200 voices, but it's not a fixed number (depends on which synth engines and which patches are in use) and not inexhaustible. In live performance you will probably never exceed its polyphony limits, but as a sequencer it's likely you will. Latency is never a problem, but dropouts can be.So all in all it's not perfect. But it's as close to perfect as I could hope for.
