Sound Engines SGX-2 Premium Piano

• This sound generator lets you perform with the sounds of famed grand pianos such as the German piano, on which ambient sounds can be freely modified; or the Italian grand piano, whose sound is growing rapidly in popularity over recent years. These pianos offer delicate expressiveness to capture every last nuance of the acoustic piano, with 12-step velocity-switched sound, string resonance, and more.
• With the damper pedal is 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 accurately captures and recreates this sympathetic string resonance, adding an additional level of detail to the grand piano sound.

EP-1 MDS Electric Piano

• This dedicated electric piano sound generator realistically reproduces seven different famous electric piano sounds, with the addition of an earlier model featuring characteristic distortion. MDS (Multidimensional Synthesis) technology eliminates 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.
• Each of the seven different models, different amps, cabinets, speakers, and standard vintage effects are realistically simulated. From the samples, to the touch, to the effects, all aspects affecting the sound are coordinated into a single package, making this the ultimate electric piano.

CX-3 Tonewheel Organ 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 NAUTILUS, 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, using the NAUTILUS' 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 HD stands for High Definition, indicating the 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. The 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 the NAUTILUS. 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 the NAUTILUS. The finest technicians, working on the finest platform, and aiming at the finest quality—that's the HD-1. MS-20EX Legacy Analog Collection Packed with cutting-edge technology, NAUTILUS nonetheless has respect for the classics. The 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) the MS-20EX faithfully reproduces the 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 NAUTILUS version is now majorly polyphonic. PolysixEX Legacy Analog Collection The Polysix first appeared in 1981, offering six-voice polyphony and 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, the PolysixEX extends the abilities of the original in many creative ways. The strings and pads that were such a major feature of the Polysix will be invaluable when you need the sounds of the early '80s. The classic arpeggiator built into the original Polysix is provided. As a bonus, it's also capable of extremely high polyphony. AL-1 Analog Synthesizer Feature packed, the AL-1 is the same premium analog-modeling sound engine that was first featured on the KORG OASYS, the 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 were unobtainable for analog synthesizers of the past. MOD-7 Waveshaping VPM Synthesizer This sound engine uses VPM synthesis based on the VPM (Variable Phase Modulation) technology that powered two classic instruments—the Prophecy appeared in 1995; and the Z1 appeared in 1997 as a further evolution, adding PCM sample playback, multimode filters, and external input to create a freely patchable semimodular synthesizer. Combine Variable Phase Modulation (VPM) from KORG's classic Prohpecy and Z1, add in some waveshaping and a little ring modulation, mix in a few samples, and add subtractive synthesis, plus a modular patch-panel system, and you have the 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 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. Additional Features Optimized for Live Performance Set Lists provide easy on-screen selection of Programs, Combinations, and Songs from a single screen. Smooth Sound Transitions (SST) provide overlapping effects and voices when you change sounds, with no special mode necessary. Effects The Nautilus AT comes with 197 types of professional-grade effects that offer a stunning range of freedom, including chorus, delay, reverb, amp models, vocoders, and more. Arpeggiator To support your playing and songwriting, there's an arpeggiator that can automatically generate rhythmical or broken chords (arpeggios), a drum track for quickly playing drum patterns in a variety of styles, and a step sequencer that lets you intuitively create and play back original drum patterns. Sampling Audio signals coming through the analog inputs can be sampled in stereo. You can also add the built-in effects when sampling, or even resample the programs or combinations. The Nautilus can import sound files in various formats. Audio and MIDI Sequencer The sequencer provides 16 MIDI tracks and 16 audio tracks (24-bit, 48 kHz) for composing and producing your own music. You can import and export SMF and WAVE files when working with other platforms. USB Functionality The Nautilus can connect to your computer with a single cable, as it features a USB-B port that supports USB 2.0 for transmitting and receiving MIDI and audio data. The Nautilus features a USB-A port for easy connection to an external storage device.
