Dazzling and Streamlined - The Korg Nautilus 73 Performance Synthesizer Workstation

NAUTILUS pushes the boundaries of what a performance synth and workstation is capable of. With the power of nine engines to drive a new approach to sounds, plentiful sampling, audio recording, effects, and processing power, there is simply no other synth that delivers more to explore sonically, with the workflow to get you there faster than ever. Korg spent years refining all our digital, analog, processing, and hardware technologies and delivering them in a way that helps the musician connect with their instrument. The result is the incredibly powerful, one-of-a-kind NAUTILUS.

Nine different sound engines offer massive expressive power. The Nautilus features nine dedicated sound engines to realistically reproduce sounds such as pianos, electric pianos, organs and more. To start, the enhanced SGX-2 piano sound generator offers delicate expressiveness to capture all the nuances of the acoustic piano, and NAUTILUS features the most piano libraries ever put into one product; with 12-step velocity-switched sound, string resonance and more. The EP-1 electric piano sound generator realistically reproduces seven different famous electric piano sounds. The CX-3 engine - the heart of our sought-after CX-3 reissue - covers the distinct sound of classic tonewheel organs. Add to that MOD-7 VPM/FM synthesis, the PolysixEX and MS-20EX for analog modeling, and the STR-1 for physical modeling, and you have essentially an engine for any type of sound you’re looking to get. Used together in Program or Combination mode, these distinctive engines create completely new timbres.

A User Interface Designed for Easy Operation

For the NAUTILUS, Korg has completely rethought the user interface, considering that panel controls tend to become denser as more functions are added. The interface of the NAUTILUS lets users find just the things they're looking for once they understand the principles. The MODE button lets you see what you've selected in each mode on a single screen, from PROG and COMBI to the set list, sampling, sequence and global modes. Each mode has tabs for each function, and the PAGE buttons offer more detailed editing with consistent operations. With the user-friendly navigation of the NAUTILUS, you can press the MODE button at any time to return to the start if you get lost. A dark mode is available for the display, using black as the primary color to reduce eye fatigue.

Six quick access buttons are also available as shortcut buttons. The NAUTILUS further offers four templates as a continuation of the previous user-friendly features, which 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 as you like. What’s more, you can freely assign functions you frequently use and save them in one of four sets.

Make Delicate Expressions and Intuitive Changes with the DYNAMICS and Realtime Knobs

With the DYNAMICS knob, you can instantly control the changes in volume and tone in response to how hard you play the keyboard (velocity); and you can customize this knob in real time to match the keyboard playing feel required for each style and song. Even when playing the same sound, you can turn this knob to get the feeling of playing a completely different sound. By finding just the right setting for your playing style, you'll uncover even more of the possibilities that the NAUTILUS offers.

When you activate the DYNAMICS knob and turn it to the left, the keyboard responds more softly to your playing, giving you a wide range of dynamics. This allows for delicate, expressive playing when accompanying a piano solo or vocals, which directly reflects the dynamics of your performance. On the other hand, turning the knob to the right gives a stronger, more flat dynamic response. This brings out the sound when you’re playing in a band or ensemble, which works best when performing with a more even feel.

New Sounds Offered Over Three Broad Categories

The approach to the included sound on NAUTILUS, started with Korg setting aside their preconceptions of what sound should be like on a conventional music workstation, and instead focusing on pushing the boundaries of sampling and programming to create a brand-new classifications of programs that they divided into three groups:


"Unique" Sounds- The NAUTILUS brings you distinctive sounds including phrase loops, prepared pianos, found percussion and more. Many seldom heard-of musical instruments found in different regions around the world can be difficult to play, but distinctive phrases played on these instruments are featured on the NAUTILUS. Use these phrases as-is in your songs - let your imagination be your guide. The NAUTILUS features sounds that were sampled for the first time just for this instrument, including prepared piano sounds created by placing different objects between piano strings and recording samples, or "found percussion" sounds made by turning ordinary items into instruments to be struck. Not only do these novel and mysterious sounds provide an unexpected flavor to your songs, they offer broad possibilities for sound effects used in film and TV music as well.

"Current" Sounds- The NAUTILUS also offers the freshest sounds that blend in well with today's music scene, including synths, drum kits, special effects and more. For synths, be sure to check out the EDM, electro and chiptune sounds for starters. Also, the NAUTILUS features more than 50 kinds of drum kits - sounds that most strongly reflect the changes in music over time. The special effect sounds offer useful material like drums added to dance music to create beats - sounds that you can put to use right away.

Standard Sounds- Korg brought together all of the most important sounds a workstation needs including piano, electric piano, guitar, bass guitar and more, covering all genres. For the newly sampled piano sound, they've also recorded the lovely sonic ambience of the studio, and you can mix the piano and ambience sound as you like with the new ambience sound. A new electric piano model with a characteristic thick sound has been added, which works great for funky playing styles. The NAUTILUS also adds many phrases that let you play back actual performances of guitar and bass parts that keyboardists will find useful.
