SGX-2 grand piano sound engine
The Kronos piano engine offers huge collections of non-looped, natural decay stereo samples recorded for every key, with additional unique tools to customize the piano to your needs. The SGX-2 Grand Piano engine adds the new Berlin Grand piano to the deep German Grand and lively Japanese Grand. The Berlin Grand offers resonant piano sound with a striking sense of depth. Other enhancements to the SGX-2 engine include sympathetic string resonance and newly-recorded una corda (soft pedal) samples.
Massive sound selection
Kronos comes equipped with thousands of sounds created using various synthesis modes and calling upon over approximately 21GB of preset waveform data covering a variety of genres. Each one has been carefully crafted by the Korg sound design team. The internal SSD offers a generous 62GB capacity, providing enormous space for user sampling or downloading Kronos sound libraries. These optional expansion Kronos sound libraries add new professionally programmed sounds without the need to add any new hardware. Artist signature programs provide the priceless sounds actually used by top-ranking musicians. Additional song programs are named for the classic rock and pop songs whose signature keyboard sounds these programs recreate. Use these universally well-known sounds to pay homage to the originals or as the basis for personal sonic explorations.
Nine distinct sound engines
Each of the individual Kronos sound engines is eminently qualified to operate as a standalone synthesize, and each one represents the cutting-edge technology available for that type of sound creation. Exacting programming parameters, real-time controllers, integrated effects and assignable modulation routings provide incredible control for the creating custom edits or for the ambitious sound designer.
Innovative set list mode
Kronos can organize all of the resources you need to get through a song or a set using set list mode. Using set list mode, the TouchView display can host 16 color-coded touchscreen buttons; each one can instantly call up the appropriate preset, combination or sequence, regardless of mode. You can even add handy performance notes ('sing on chorus,' 'transpose down,' 'wait for sax solo,' etc.) to each one. Set list mode even adds a nine-band graphic EQ, allowing the overall tone to be tweaked to match the venue. Set list mode allows for even deeper customization with many slot color options, text size variations and a full-screen text editor. Connecting a USB computer keyboard makes it simple to enter text and numeric values.
Color TouchView display with touch-drag capability
The nerve center of Kronos is Korg's enormous eight-inch 800×600 pixel SVGA color TouchView display. In addition to simply selecting a sound or choosing a parameter with the touch of a finger, touch-drag ability allows more detailed control of parameter values. Interactive instruments and panel graphics provide the ability to do everything from adjusting the lid of a grand piano to connecting patch cable on a semi-modular synthesizer model. The TouchView display also hosts a convenient search function, allowing you to search for (and preview) sounds based on their titles.
Sequencer composition tools
In addition to MIDI and audio tracks, the onboard sequencer is loaded with valuable tools to transform your musical ideas into a complete composition using realtime and interactive techniques that are unavailable or cumbersome to use on a computer-based system.
First appearing on Korg's Karma Music Workstation in 2002, this revolutionary algorithmic music technology instantly produces sophisticated phrases, drum grooves and full-blown backing tracks. Based on the notes and chords you play as well as the intuitive operations you perform with the knobs, sliders and switches, KARMA can create musical effects that exceed anything you imagined. Now in its greatly-enhanced second generation and offering features like KARMA wave sequencing, note mapping and 8 scenes per layer, KARMA is standard equipment on Kronos. It will expand your conception of a song and will be an enormous asset to your live performances.
This function that plays drum patterns automatically was included and highly acclaimed on Korg's M3 music workstation/synthesizer that appeared in 2007. Kronos is the latest Korg workstation to offer the drum tracks features. Drum tracks can create everything from a simple reference beat to an outline rhythm track on up to a full-blown drum track for your music productions. Expanded for use in Kronos, drum tracks includes professional drum performances and is ready and able to generate grooves that capture the distinctive feel of a pro drummer.
Open Sampling System
Using Korg's Open Sampling System, Kronos can quickly sample an external audio source, regardless of whether Kronos is in program, combination or sequencer mode. Open Sampling Mode can even resample the performance of Kronos itself. The user sample bank, which extends the convenience of the EXs sample library to user samples, allows custom samples to be loaded and played, taking advantage of the gigantic SSD capacity. AIFF, WAV, SoundFont 2.0 and AKAI S1000/3000 format samples can be loaded into memory via USB. Additionally, you can use a USB ethernet adapter to exchange large amounts of sample data with your computer at high speed. Instruments or samples that you've previously created on your PC can be used to construct a music production setup based on just Kronos itself.
16-track MIDI sequencer / 16-track audio recorder
Kronos features a sequencer/recording section that offers 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 Kronos itself and place the resampled WAV files directly in a track. When polishing your tracks, feel free to use mixer automation and editing functions such as 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!
16 onboard effect processors
Kronos 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. 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.
USB/MIDI host ports accommodate MIDI control surfaces
Any class-compliant USB MIDI controller can be connected directly to Kronos. If you connect a Korg pad-equipped USB MIDI controller (nanoPAD, nanoPAD2, padKONTROL), pads 1 through 8 of the controller are automatically mapped to the virtual chord pad function of the Kronos, allowing them to be used to play drums, trigger chords or switch chords in chord mode.
Advanced control surface
In addition to the parameters accessible directly from the TouchView display, Kronos also offers a wealth of realtime controllers to enhance any performance and to aid navigation. A four-way joystick, ribbon controller and two assignable switches are located to the left of the keyboard. An additional vector joystick is nearby. Above the keyboard, nine sliders, eight knobs and a number of switches provide realtime interaction with features at the heart of Kronos' impressive sound. The damper pedal input jack supports half-damping, providing one more level of piano realism. In addition to the damper pedal jack, there are also two assignable pedal inputs: one footpedal type and one footswitch style.
Flagship RH3 weighted hammer action
88-key Kronos models use Korg's finest RH-3 real weighted hammer action. Offering an authentic and accurate piano feel, there are four zones ranging from heavier to lighter to provide a truer piano playing experience. And the 88-key model is still slim enough to place on a standard keyboard stand! Kronos achieves the perfect balance of functionality and design.
Smooth sound transitions that eliminate dropouts when changing sounds, regardless of the mode you're in
When you switch program sounds during a performance to get ready for the next section or when you switch from Program mode to Combi mode, the sound that's currently being output is always given priority and its effects are maintained during the program change, ensuring a seamless transition with no dropouts.
Nine synthesizer engines, united in one instrument
Kronos harnesses nine distinct synthesizer/sound engines into a single, integrated musical instrument. Dynamic voice allocation and new technologies allow all sound engines to smoothly share a stable, enhanced hardware platform. The results are nothing less than spectacular.
SGX-2 (Premium Piano) piano sound engine
Choose your piano! In addition to the acclaimed German Grand and Japanese Grand, Kronos SGX-2 Premium Piano includes the distinctive Berlin Grand. By adding the EXs12 Austrian Grand option (sold separately), Kronos can offer access to the greatest names in the grand piano world. Unlooped stereo samples recorded for every key provide a natural, authentic decay. Kronos offers 12-level velocity switching, while features such as as pedal string resonance and una corda sample data recreate every detail of a grand piano performance.
String resonance: With the damper pedal depressed, all of the piano strings are free to resonate. When any key is played on the piano, other strings that are pitch-related to the original key may begin to vibrate via sympathetic resonance. The SGX-2 engine accurately captures and recreates this sympathetic string resonance, adding an additional level of detail to the grand piano sound.
Una corda: The pedal to the far left on a grand piano is the 'soft' pedal; the technical name for this pedal is una corda. Una corda translates literally as 'one string.' Normally, the piano hammer strikes all of the strings tuned to a particular note, usually three or two. Pressing the una corda pedal shifts the entire piano action so that the hammer hits only one string. The resulting sound is lower in volume and has a more muted tone. The SGX-2 piano engine contains una corda samples that can replicate this subtle shift in volume and tone to provide a faithful piano performance, complete with all pedal actions.en.
EP-1 (MDS Electric Piano) electric piano sound engine
The Kronos EP-1 sound engine is dedicated to faithfully recreating six of the most popular classic electric pianos. The MDS (multi-dimensional synthesis) technology eliminates the transitions between velocity-switched samples and does away with the unnatural behavior of looped samples. Smoothly responding to the nuances of the player's touch yet allowing your performance to reach an energetic climax, this modeled engine features an astounding dynamic range that exceeds what one might expect from digital sound generation. For each of the six different models, different amps, cabinets, speakers and standard vintage effects are realistically simulated. From the samples to the touch and the effects, all aspects affecting the sound are coordinated into a single package, making this the ultimate electric piano.
CX-3 (Tonewheel Organ) tonewheel organ sound engine
The original Korg CX-3 combo organ went on sale in 1980. Loved by musicians around the world, this classic organ reappeared in 2000 as a new product with the same name but using the latest technology. In Kronos, the CX-3 engine precisely models this classic tonewheel instrument. Proprietary Korg technology has been used to perfectly reproduce the vacuum tube amp and effects such as vibrato/chorus. Special attention was given to the rotary speaker effect, which lets you choose from seven types as well as use Kronos' joystick in the X-axis to control the speed. Even the instability, fold-back, leakage and noise of the tonewheels have been obsessively analyzed and recreated. The organ sounds heard in legendary performances — some recreated here by the original artists — are now yours for the playing. Experience these classic organ sounds, reborn for the present day.
HD-1 (High Definition Synthesizer) PCM sound engine
HD stands for 'high definition,' indicating HD-1's superior sound, starting with Korg's proprietary low-aliasing sample playback oscillators, full-bandwidth multimode resonant filters and extraordinarily fast and smooth envelopes and LFOs. HD-1 is the most powerful PCM sound engine in Korg's history, into which Korg has poured all the PCM know-how accumulated since the M1. All of Korg's acclaimed PCM sounds are painstakingly created by specialized technicians. Data that was reluctantly omitted from previous models due to limited memory has now been called back into service on Kronos. The amount of waveform memory alone might rival a PC-based sound engine, yet the real difference is in the completely different level of quality and finish that is obvious when you play these sounds as instruments on Kronos. The finest technicians, working on the finest platform and aiming at the finest quality: that's HD-1.
MS-20EX (Legacy Analog Collection) analog modeling sound engine
Packed with cutting-edge technology, Kronos nonetheless has respect for the classics. Korg MS-20 first appeared in 1978 and quickly captivated many synth fans with its rich personality marked by thick and solid sound, aggressive filters and patching capability that provided nearly infinite possibilities for creating sound. Using Korg's CMT (component modeling technology), MS-20EX faithfully reproduces MS-20 while dramatically expanding its patch panel functionality. Modulate filters with audio-rate oscillators, turn audio inputs into control signals, control all of the original knobs with mod sources including additional envelopes, LFOs, and real-time controllers — it's a tweaker's dream. And, of course, the Kronos version is majorly polyphonic.
PolysixEX (Legacy Analog Collection) analog modeling sound engine
Korg Polysix first appeared in 1981, offering six-voice polyphony, program memory and a surprisingly competitive price tag. With its self-oscillating four-pole filter, smooth analog oscillator and sub-oscillator, plus a lush chorus/ensemble effect, PolysixEX extends the abilities of the original in many creative ways. The strings and pads that were such a major feature of Polysix will be invaluable when you need the sounds of the early 80s. The classic arpeggiator built into the original Polysix is also provided. As a bonus, it's also capable of extremely high polyphony.
AL-1 (Analog Synthesizer) high-fidelity analog modeling sound engine
AL-1 is the same premium analog modeling sound engine that was first featured on Korg OASYS back in 2005. Completely eliminating aliasing noise and delivering the supple and fascinating sound of analog synthesis, this sound engine uses oscillator waveforms and filter morphing to generate new sounds that were unobtainable for analog synthesizers of the past.
MOD-7 (Waveshaping VPM Synthesizer) VPM/FM synthesis sound engine
This sound engine uses VPM synthesis based on the VPM (variable phase modulation) technology that powered two classic instruments — the Prophecy, which appeared in 1995, and the Z1, which appeared in 1997 as a further evolution — and adds PCM sample playback, multi-mode filters and external input to create a freely patchable semi-modular synthesizer. Take VPM, add in some wave-shaping, a little ring modulation, mix in a few samples and add subtractive synthesis plus a modular patch-panel system, and you have MOD-7. Exceptionally versatile, it offers everything from classic FM keyboards, bells and basses (including the ability to import sounds from vintage DX synths) to rhythmic soundscapes and sparkling, epic pads.
STR-1 (Plucked Strings) physical model sound engine
Based on the physical modeling know-how Korg developed over the course of many years, this struck/plucked-string physical modeling sound engine takes advantage of cutting-edge technology. This sound engine shines at producing sounds whose tone responds to your touch in ways that are difficult for a PCM sound engine to reproduce: acoustic guitar, electric guitar, harpsichord, clavinet, harp, bell, as well as ethnic instruments. It also goes much further, allowing you to synthesize and modify sounds that do not exist in reality. This is a sound engine of the future, one that allows the synthesizer programmer to construct truly new sounds.
