Korg's dedication to long-term support ensures all Kronos systems can use the many and varied Kronos Sound Libraries, preserving your investment and enabling seamless upgrades when hardware is refreshed.
Kronos Sound Libraries, a vast library of extended sounds
Kronos Sound Libraries, a library of extended sound samples and programs, has been released steadily since the first Kronos was introduced, and boasts a lineup of more than 300 titles, each with a unique selection that is different from the preloaded programs in the main unit. These titles can be purchased separately and used with all Kronos products. The Kronos sound engine is designed to accommodate any genre of music, and to be used in a variety of situations by any user. Kronos Sound Libraries allow you to find and purchase your preferred sounds and genres that are not included in the main unit, and change your Kronos 3 to your liking.
Enhanced SGX-2 Grand Piano sound engine with the addition of a premium Italian grand
The Kronos piano engine has always offered the highest quality non-looped, natural decay stereo samples, recorded for every key with additional unique tools to customize the piano to your needs. Inheriting all of this SGX-1 functionality, the enhanced SGX-2 Grand Piano engine introduces the Berlin Grand piano to the existing deep German Grand and lively Japanese Grand. The Berlin Grand offers resonant piano sound with a striking sense of depth. In addition to these three pianos, it is equipped with a gorgeous and transparent Italian Grand – four very different Grand Pianos to choose from. Other enhancements to the SGX-2 engine included Sympathetic String Resonance and newly-recorded Una Corda samples. (The newly added Italian Grand does not include the effects of Una Corda.)
Massive sound selection
Kronos 3 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 additional Kronos Sound Libraries. These optional 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 synthesizer, and each one represents the cutting-edge technology available for that type of sound creation. Exacting programming parameters, realtime controllers, integrated effects and assignable modulation routings provide incredible control to create custom edits or to empower the ambitious sound designer.
Flagship RH-3 Real Weighted Hammer Action
The 73-key Kronos 3 uses Korg's finest RH-3 Real Weighted Hammer Action made in Japan. Offering an authentic and accurate piano feel, there are four zones ranging from heavier to lighter to provide a more true piano playing experience.
Advanced control surface
In addition to parameters accessible directly from the TouchView display, Kronos 3 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 ideally positioned for easy access. Above the keyboard, nine sliders, eight knobs and a number of switches provide realtime interaction with features at the heart of Kronos 3's impressive sound. The damper pedal input jack supports half-damping, providing yet another 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.
Set List mode
Kronos 3 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 touch-screen 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 adds a dedicated 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
The nerve center of Kronos 3 is Korg's enormous 8" 800×600 pixel SVGA color TouchView display. In addition to simply selecting a sound or choosing a parameter with the touch of a finger, the enhanced touch-drag ability allows more detailed control of parameter values. Interactive instruments and panel graphics provide the ability to do everything from adjusting the opening height of a grand piano lid to connecting patch cables 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.
Karma
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 – Karma can create musical effects that exceed anything you imagined. Now and offering features like Karma Wave-Sequencing, Note Mapping and 8 scenes per layer, Karma is standard equipment on Kronos 3. It will expand your conception of a song, and will be an enormously inspiring creative asset for all composing.
Drum Tracks
First introduced in the highly acclaimed M3 music workstation/synthesizer that launched in 2007, Drum Tracks is now featured in Kronos 3. Drum Tracks can create everything from a simple reference beat or outline rhythm track up to a full-blown drum track. Expanded for use in Kronos 3, Drum Tracks now includes professional drum performances and generates grooves that capture the distinctive feel of a pro drummer, challenging the capabilities of standalone drum machines.
Open Sampling System
Using Korg's Open Sampling System, Kronos 3 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 large SSD capacity. AIFF, WAV, SoundFont 2.0 and AKAI S1000/3000 format samples can be loaded via USB memory. 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 3.
16-track MIDI sequencer / 16-track audio recorder
Kronos 3 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 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. Then you can assemble your album right from the TouchView display!
16 onboard effect processors
Kronos 3 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 3. If you connect a Korg pad-equipped USB MIDI controller such as NanoPad, NanoPad2 or PadKontrol, pads 1 through 8 of the controller are automatically mapped to the virtual chord pad function on Kronos 3, allowing them to be used to play drums, trigger chords or to switch chords in chord mode.
Smooth sound transitions 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, something that has earned high praise from pro musicians.
Nine engines united in one Instrument
Kronos 3 harnesses nine distinct sound engines into a single, integrated 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
In addition to the German Grand and Japanese Grand in the SGX-1 engine, the enhanced Kronos 3 SGX-2 Premium Piano includes the Berlin Grand and New Italian Grand. By adding the EXs12 Austrian Grand (sold separately), Kronos can access the greatest names in the grand piano world. Unlooped stereo samples recorded for every key provide a natural, authentic decay. 12-level velocity switching exceeds the previous 8-level data, and nuanced extras such as pedal string resonance and una corda help recreate the finer details of a grand piano.
EP-1 electric piano
The Kronos 3 EP-1 sound engine is dedicated to faithfully recreating six of the most popular classic electric pianos, and Tine EP I Early has been added.Multi-Dimensional Synthesis technology eliminates transitions between velocity-switched samples and does away with the unnatural behavior of looped samples. For each of the six different models, different amps, cabinets, speakers and standard vintage effects are realistically simulated.
CX-3 tonewheel organ
The CX-3 engine models Korg's classic 1980 instrument. Proprietary technology reproduces 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 and use the Kronos modulation joystick to control speed. Even the instability, foldback, leakage and noise of tonewheels have been analyzed and recreated. KRS-06 and 06B expansion libraries are also included and can be loaded for use with 256 programs.
HD-1 high-definition PCM synthesizer
HD stands for 'high definition,' starting with Korg's proprietary low-aliasing sample playback oscillators, full-bandwidth multimode resonant filters and extraordinarily fast and smooth envelopes and LFOs. 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 3. The amount of waveform memory rivals a PC-based sound engine.
MS-20EX analog modeling
Korg MS-20 first appeared in 1978 and captivated many synth fans with its thick and solid sound, aggressive filters and patching capability. Using Korg's Component Modeling Technology, MS-20EX faithfully reproduces MS-20 while expanding its patch panel functionality. Modulate filters with audio-rate oscillators, turn audio inputs into control signals and control all of the original knobs with mod sources. And of course, the Kronos version is majorly polyphonic.
PolysixEX analog modeling
1981's Polysix offered 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. The strings and pads 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 high-fidelity analog modeling
Feature-packed, AL-1 is the same premium analog modeling sound engine that was first featured on Korg OASYS Open Architecture Synthesis Studio 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 unobtainable on analog synthesizers of the past.
MOD-7 waveshaping VPM/FM synthesis
Based on the Variable Phase Modulation technology that powered Korg Prophecy and Z1, MOD-7 adds PCM sample playback, multi-mode filters and external input to create a patchable semi-modular synthesizer. Combine VPM with wave-shaping and ring modulation, mix in samples and add subtractive synthesis plus a modular patch panel and you have MOD-7, offering 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
Based on physical modeling know-how developed over many years, this struck-/plucked-string 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.
