These are joined by the <strong>MOD-7: VPM / FM, PolysixEX</strong> and <strong>MS-20EX</strong> synthesis modules for analog modeling, and <strong>STR-1</strong> for physical modeling. Used individually as Programs or combined in Combinations, the Sound Engines produce all the sounds of <strong>NAUTILUS-61 AT</strong>, from <strong>Vintage</strong> to the most modern or futuristic.</p><p style="text-align: center;"><strong><img alt="KORG NAUTILUS-61 Integrates an advanced multisynthesis sound engine with 9 different Sound Engines" src="https://www.algameko.com/images/uploads/Nautilus_LS_Photo_02.jpg" title="KORG NAUTILUS-61 Integrates an advanced multisynthesis sound engine with 9 different Sound Engines" /></strong></p><h2><strong>NAUTILUS-61 AT SST Smooth Sound Transition</strong></h2><p style="text-align: justify;">On <strong>NAUTILUS-61 AT</strong>, selecting different operational modes or musical resources does not cause any sound interruption. It is possible to recall <strong>Programs</strong> or <strong>Combis</strong>, switch from Program to Combi mode, or even move between Songs on the Sequencer, while maintaining the original decay and effects during changes, with a seamless transition without interruptions. This feature is widely appreciated and praised by all musicians.</p><h3><strong>NAUTILUS-61 AT the Sound Library</strong></h3><p style="text-align:justify">For timbre selection on <strong>NAUTILUS-61 AT</strong>, a completely new approach has been applied, setting aside all preconceptions and conventions regarding Workstations, thus creating a new classification system capable of transcending the boundaries of sampling and Sound Design. On <strong>NAUTILUS-61 AT</strong>, sounds are divided into three main groups:</p><ul> <li> <p><strong>Exclusive Sounds</strong></p> </li></ul><p>In this category, <strong>NAUTILUS-61 AT</strong> offers unique and distinctive sounds such as <em>Loops</em> with musical phrases, prepared pianos, original percussion, and much more. Characteristic musical phrases from rare instruments, difficult to find and play, have been created and included in the internal sound library, freely usable in your musical pieces; and other unusual timbres such as the "<em>prepared</em>" piano, whose timbre is modified by inserting screws, small pieces of wood, and other objects between the strings, with very suggestive results; or percussion sounds created using ordinary objects like kitchen utensils or other items. These sounds can add original colors to your compositions or arrangements, and also represent a valuable resource for musicians who create sound design and music for visuals.</p><ul> <li> <p><strong>Modern Sounds</strong></p> </li></ul><p style="text-align:justify"><strong>NAUTILUS-61 AT</strong> features the most up-to-date timbres suitable for the current music scene in genres such as EDM, Electro, and Chiptune; with the most modern Synth and Drum Kit timbres, and special effects that also facilitate the creation of effective Dance beats and grooves. The instrument's over 50 Drum Kits offer a wide variety of percussive sounds capable of adequately representing the rhythmic evolution in musical styles of recent decades.</p><ul> <li><strong>Standard Sounds</strong></li></ul><p style="text-align:justify">On <strong>NAUTILUS-61 AT</strong>, essential sounds for a Workstation have been carefully crafted: acoustic pianos, electric pianos, guitars, basses, etc., to satisfy all musical genres. In the new acoustic piano sounds, the acoustics of the recording room have also been sampled, with the possibility of personally mixing the direct sound with the ambiance; and a new electric piano model with a characteristic full-bodied timbre, particularly suitable for Funk, has also been added.</p><h2><strong>NAUTILUS-61 AT dynamic control</strong></h2><p style="text-align:justify">Using the <strong>DYNAMICS</strong> knob, it is possible to control the timbre and volume variations introduced by keyboard <em>Velocity</em>, and make them match the style of the played song. Turning this knob allows you to achieve a completely different <em>feel</em>, even using the same sound. An additional method to adapt the instrument to your needs. Playing the keyboard and turning the "<em>Dynamics</em>" knob to the left produces a softer sound with a wider dynamic range, allowing for delicate and expressive passages, ideal for accompanying vocalists or solo instruments. Turning the knob to the right, the dynamic response becomes more energetic and uniform; particularly useful for making a timbre stand out more, such as in solos.</p><h2><strong>NAUTILUS-61 AT physical controls</strong></h2><p style="text-align:justify">The six <strong>RT (Real Time)</strong> knobs on the panel allow direct modification of <strong>PROGRAMS</strong> and <strong>COMBIS</strong>. A variety of functions can be assigned to each knob, such as timbre editing with Filter Cut Off, effect level; arpeggiator or Drum Track control with Gate, tempo speed, Swing, snare type, and much more. In COMBI mode, different timbres can be grouped, and their volume controlled with a single knob. To prevent accidental modification during a Performance, they can be fully recessed into the panel by simply pressing them, thus locking their position. This also allows you to select only the most frequently used ones, hiding the others.</p><p style="text-align: center;"><img alt="KORG NAUTILUS-61 Features an intuitive user interface based on a color Touch Display integrated with physical controls on the panel" src="https://www.algameko.com/images/uploads/Nautilus_LS_Photo_06.jpg" title="KORG NAUTILUS-61 Features an intuitive user interface based on a color Touch Display integrated with physical controls on the panel" /></p><h2><strong>NAUTILUS-61 AT the user interface</strong></h2><p style="text-align:justify">For <strong>NAUTILUS-61 AT KORG</strong> has redesigned the user interface to speed up and simplify every operation. Normally, adding functions tends to increase the number of physical controls on the panel, but in this case, the approach was to rationalize and optimize operational speed and intuitiveness as much as possible. The <strong>MODE</strong> button displays a single screen for selecting operational modes: PROGRAM, COMBI, SET LIST, SAMPLING, SEQUENCE, and GLOBAL. In each MODE, access to functions is obtained via TABS, while the PAGE buttons allow for more in-depth modifications with intuitive procedures. This navigation system always allows you to return to the initial stage by simply pressing the MODE button. The display operates in <em>Dark</em> mode, which uses black as the main color to reduce eye strain. There are also <strong>6 programmable shortcut buttons</strong>, which can be assigned to a variety of functions such as: selecting Program or Combi modes, transport keys for the Sequencer, etc. 4 different ready-to-use Templates are available, but it is possible to create and save your own settings.</p><h2><strong>NAUTILUS-61 AT the <a id="TouchDisplay" name="TouchDisplay">Touch Display</a></strong></h2><p style="text-align:justify">The nerve center of the <strong>NAUTILUS-61 AT</strong> user interface is the large color <strong>(800 x 480 pixels) WVGA TouchView</strong> display; with it, you can directly select or modify a sound or parameter with a simple finger touch thanks to <strong>Touch Drag</strong>. A series of graphical and interactive tools are also available to facilitate programming, such as adjusting the grand piano lid opening on <strong>SGX-2</strong>, or connecting virtual patch cables on MS-20EX. The display features a <strong>Search</strong> function, useful for locating any musical resource based on a search key.</p><h2 style="text-align: justify;"><strong>NAUTILUS-61 AT the <a id="SetList" name="SetList">Set Lists</a></strong></h2><p style="text-align:justify">The SET LIST mode of <strong>NAUTILUS-61 AT</strong> allows for personal organization of sound resources. Each SET LIST is composed of a fundamental unit called a <strong>SLOT</strong>; there are 128 SLOTS in each SET LIST, and 128 SET LISTs are immediately available. Each SLOT can be given a name and assigned a musical resource as needed: PROGRAM, COMBI, or SONG. From this, it is also possible to control parameters such as the volume of the selected resource, display text, or color it appropriately to highlight it within the list; each SLOT can also be moved and positioned as desired, or copied or deleted. This operational mode can meet any Live requirement, thanks to the ability to program the exact succession of musical resources we need. Finally, each SET LIST has a <strong>9-band graphic equalizer</strong>, placed at the end of the audio chain and <strong>independent</strong> of the effects section, with which to modify or correct the global timbre response of NAUTILUS depending on the environment in which the Performance takes place.</p><p style="text-align: center;"><img alt="NAUTILUS-88 possesses great versatility in Live use thanks to programmable Set Lists" src="https://www.algameko.com/images/uploads/Nautilus_LS_Photo_10.jpg" title="NAUTILUS-88 possesses great versatility in Live use thanks to programmable Set Lists" /></p><h2><strong>NAUTILUS-61 AT Open Sampling System</strong></h2><p style="text-align:justify"><strong>NAUTILUS-61 AT</strong> uses the KORG Open Sampling System to quickly sample an external audio source, or resample a Performance executed on NAUTILUS, regardless of the selected operating mode. The timbral possibilities offered by the instrument's vast internal Sample library are significantly expanded by the <strong>SAMPLE USER</strong> area, which, thanks to <strong>VMT (Virtual Memory Technology)</strong>, allows you to use personal samples, maximizing the Workstation's SSD capacity. <strong>Samples</strong> in various formats can be loaded via the USB port: AIFF, WAV, SoundFont 2.0, and AKAI S1000/3000; if the amount of data is truly significant, a high-speed Ethernet USB adapter can also be used. &On NAUTILUS, you can therefore use samples created on a computer for your compositions, arrangements, or productions.

NAUTILUS-61 AT the Sequencer

NAUTILUS-61 AT has a powerful Sequencer/Recorder with 16 MIDI tracks and 16 Audio tracks for creating songs or musical arrangements. This section has several functions that facilitate and stimulate musical inspiration, with the possibility of recording polyphonic arpeggiators, Drum Tracks, or RPPR (Realtime Pattern Play/Recording), resulting in professional-quality results quickly. The 16-track Audio Recorder captures up to 4 tracks simultaneously in 16-bit/24-bit 48 kHz format. During playback, effects can be added, the resulting audio resampled, and the Wav file imported into a Sequencer track. Editing functions such as Copy, Paste, Normalize, and mixing automation are also present.

Polyphonic Arpeggiator and Drum Track

These modules provide effective interactive musical support for every performance, with a wide library of rhythmic and melodic patterns; 4 different scenes are also available where different patterns can be set and instantly recalled; ideal for improvisation, for performances, or for quickly recording backing tracks or complete arrangements on the Sequencer.

NAUTILUS-61 AT the Effects

The powerful DSP section of NAUTILUS-61 AT can produce up to 16 effects simultaneously, selectable from 197 different types, divided into 3 categories: Insert, Master, and Total FX. Insert effects are applied to single or multiple timbres of a Combi's or Sequencer's Timbre/Track. Master 1&2 effects can be adjusted for all tracks with their respective sends (Send 1&2), while Total effects act globally on the entire instrument. In addition, a three-band equalizer is available for each timbre, MIDI, and Audio track of the Sequencer to correct tonal balances or to creatively modify the sound.
