New sounds offered over three broad categories
The approach to the included sound on Nautilus started with Korg setting aside its preconceptions and creating a brand new classification of programs divided into three groups:

• Unique sounds: Nautilus brings you distinctive sounds including phrase loops, prepared pianos, found percussion and more, including sounds that were sampled for the first time just for this instrument.
• Current sounds: Nautilus also offers the freshest sounds fromwith today's music scene, including synths, drum kits, special effects and more. Check out the EDM, electro and chiptune synth sounds and dive into more than 50 kinds of drum kits.
• Standard sounds: You'll also find all the workstation staples like piano, electric piano, guitar, bass guitar and more, covering all genres. Korg also added many phrases that let you play back actual performances of guitar and bass parts that keyboardists will find useful.

Make intuitive changes to sounds with realtime knobs
The six RT (realtime) knobs at the top left of the panel give you direct control over changes to the PROG and COMBI sounds. A variety of functions are assigned, such as filter cutoff and effect depth, the gate time, tempo and swing of the arpeggiator or drum track, the type of snare drum and more. In COMBI mode, you can group timbres and control their levels with the knobs. You can press these knobs into the panel to lock them in place, preventing them from being accidentally changed while you're playing and letting you enable only the knobs you need.

Six quick access buttons are also available as shortcut buttons. Nautilus further offers four familiar legacy templates that can be used to select modes like PROG and COMBI, as transport buttons for sequencer playback and recording and so on. You can also select your own settings, freely assign functions and save them in one of four sets.

Set List mode demonstrates its power in live performances
Nautilus 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, and you can set different button colors for quick and easy recall. Set List mode even adds a nine-band graphic EQ, allowing overall tone to be tweaked to match the venue.

Open Sampling System
Using Korg's Open Sampling System, Nautilus can quickly sample an external audio source, regardless of whether Nautilus is in Program, Combination or Sequencer mode. Open Sampling Mode can even resample the performance of Nautilus 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 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 entirely within Nautilus.

16 onboard effects processors
Nautilus 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 3-band EQ is provided for every timbre, for every sequencer track and for every audio track for adjusting subtle tonal balances or creatively modifying the overall sound.

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.

Free bundle of music software
Nautilus comes with a diverse variety of music software including Izotope Ozone Elements to create songs and master them using AI, Skoove to help you improve your keyboard playing skills, Reason Lite DAW software and software synths from Korg and other brands. In other words, the moment you get your hands on this synthesizer you'll have a variety of tools to help you take your music to the next level.

EP-1 electric piano sound generator
This dedicated electric piano sound generator realistically reproduces seven different famous electric piano sounds, with the addition of an earlier model featuring a characteristic distortion. 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 modelled engine features an astounding dynamic range that exceeds what one might expect from digital sound generation. For each of the seven 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.

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 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 Nautilus. The amount of waveform memory alone might rival a PC-based sound engine.

PolysixEX analog modeling sound engine
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.

MOD-7 waveshaping VPM/FM synthesis sound engine
This sound engine uses VPM synthesis based on the VPM (Variable Phase Modulation) technology that powered two classic instruments, Korg Prophecy which appeared in 1995 and 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. Combine Variable Phase Modulation (VPM) from Korg's classic Prohpecy and Z1, 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.
