Professional musicians and producers in search of a powerful music creation station with nuanced performance controls will appreciate Korg Nautilus AT, the flagship music workstation with an upgraded keyboard; now with aftertouch. The Nautilus AT offers a vast palette of sounds, integrated editing, detailed 7" TouchView display with gesture support, 16-track sequencer, 16-track audio recorder, and extensive sampling capabilities. With the upgraded keyboard, the sound engine and content library have been updated and expertly fine-tuned to provide exciting aftertouch-controlled effects to existing programs plus new content.
The Nautilus AT includes Essential and Future sound sets for a total of 3000 programs and combinations. The instrument features nine distinct sound engines, with each engine dedicated to authentically reproducing its respective instrument type, including detailed pianos, vintage keyboard sounds, tone-wheel organs, ethnic instruments, plucked instruments, analog synthesizers, and more.
The sequencer can access any combination of sound engines and imported samples, and the 16-track audio recorder can be used for recording vocals, other instruments, and more. The sound architecture offers a two-part split along with a single drum track in a single program, which when combined with the 16-part combination mode, makes for a massive sound and sequencing power house. The Dynamic Polyphony Allocation and Smooth Sound Transition provides uninterrupted playing and sound switching.
The Nautilus is equipped with over 197 different effect types and can use up to 16 simultaneous effects and 32 simultaneous EQs for massive production power. You'll have plenty of hands-on control thanks to the streamlined TouchView interface and control panel with customizable mode buttons. The Nautilus delivers professional sound quality and capabilities in an affordable, streamlined performance synthesizer.

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 the 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 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 (Multi-Dimensional 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, as well as use 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 also 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, 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 also 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 Type-B port that supports USB 2.0 for transmitting and receiving MIDI and audio data. The Nautilus features a USB Type-A port for easy connection to an external storage device.

Warning: This Journal Will Pull You In
Format: Hardcover, Format: Hardcover
Before I read it, I believed this journal was a kind of encyclopaedia of all the mysteries and unexplained events of Gravity Falls. However, it turned out to be something entirely different—an intriguing work of fiction, a captivating page-turner, and a perfect TV-series companion that everyone should have at hand while watching the adventures of Dipper and Mabel Pines and their friends during that one iconic summer.
★★★★★ Art
This is a one-of-a-kind book! I’ve never come across anything like it. It is, quite literally, a diary—a journal written and designed with 100% authenticity. You’ll find hand-drawn illustrations and handwritten text sections, as if an explorer, researcher, or scientist documented all of their personal experiences while investigating the eerie town of Gravity Falls. Some pages convey pure emotion; others offer meticulous descriptions of the unknown. Altogether, it grips you and doesn’t let go until you reach the final page. Now I truly understand how Dipper felt when he found this journal—excited, curious, and full of wonder. Bravo!
★★★★☆ Text
In addition to everything mentioned above, the text itself is deeply immersive and engaging. The book consists of two main parts (without spoiling the essence): one written by an unknown author, and another by Dipper, who finds the journal and continues it by chronologically recording his and Mabel’s adventures.
The variety of fonts brilliantly reflects different personalities and emotional states: trembling handwriting, unstable and chaotic notes seemingly written by a mad scientist; Dipper’s neat, school-like typeface; and Mabel’s colorful, emotional, and expressive writing—almost as if she’s permanently fueled by a generous dose of sugar.
For readers who enjoy deciphering codes and riddles, the journal contains puzzles and sections written in several ciphers. Personally, though, these felt more decorative than engaging: sitting with a sheet of paper and decoding letter by letter isn’t quite the experience I want from a book like this. I would have preferred overlays, often used in art books, that reveal the decrypted message beneath without breaking the sense of immersion.
★★★★★ Book Design
Starting with the cover—designed to look like a real, well-worn journal—it feels authentic straight away, just like in the show. There are even intentionally distressed areas on the cover, suggesting damage and wear, which adds another layer of believability. Portrait orientation, size, weight, paper quality, font selection—everything is executed with an incredible level of care and love.
The only downside is the dust jacket, which can easily wear out or get lost. Without it, the book title isn’t printed on the cover underneath. Still, since the cover perfectly replicates the journal from the show, this small flaw is easy to forgive.
★★★★★ Price
I still can’t quite understand how such an incredible book can be sold for such a modest price. Perhaps it’s due to the large number of copies available on the market, but even so, it remains one of the best price-to-quality ratios among the books I’ve purchased in recent years—not to mention the overwhelming number of copies available on the pre-owned market.
★★★★★ Overall Impressions
We all know that Gravity Falls is a masterpiece. What I truly regret is that no one ever told me how much more fascinating and immersive the show becomes when you watch it with this journal in hand. You read the first part, get acquainted with the main characters, and then return to the journal after each episode—as if you’re staying right beside them at the end of the day, listening as they write down everything that happened. I could almost smell the wood of the Mystery Shack and hear the evening crickets outside the window while imagining it all.
In short, this journal is an absolute must-have if you’re a fan of the show—or if you have kids of the right age who are ready to watch it and join its worldwide fan community.
The biggest drawback of this journal is that it’s Journal #3. Journals #1 and #2 exist only as single pages shown in the series—forever teasing your imagination and teaching your inner perfectionist to accept this universe as it is, while firmly believing that somewhere in parallel dimensions, Journals #1 and #2 are all-time bestsellers.

A Must-Have for Gravity Falls Fans
Format: Hardcover
I absolutely loved this book. I’m a big Gravity Falls fan, and having Journal 3 in physical form just feels different. It really feels like the actual journal from the show. There are so many details, drawings, and hidden things that you don’t fully see in the episodes, which makes it even more special.
I was honestly surprised by how well made it is. The pages, the cover, everything looks amazing. I had so much fun reading it and looking for secrets. If you like Gravity Falls, it’s 100% worth buying. I don’t regret it at all. 💛📖

Terrific Gift - With One Big Catch
Format: Hardcover
There's one thing that you really need to know about this book before ordering. And by all means, you should definitely order it if you or someone that you love is a fan of Gravity Falls. I watch the show with our Daughter, who also happens to be a diehard Bill Cipher fan. And she absolutely loves this book, it made her so happy to get it as a Christmas present. It's visually amazing, awesome illustrations, good colors. Just full of cool stuff that will appeal to any fan of the show.
But, there's one catch.....
A good portion of the book includes writing that's in cursive. Back in 2010, Common Core led to most states dropping requirements for students to learn writing in cursive. In the years that followed, about half of the states in America changed their tune. But it's entirely possible that you live in a state that doesn't require it to be taught in public schools. So if your child doesn't know how to read cursive, there's going to be parts of the book that they simply can't read. But even if they can, there are also parts of the book in which the writing is very small, or the graphics look almost pixelated and slightly fuzzy. Which still makes certain parts a little difficult to read.
That said, should you still buy the book? 100% yes, because that doesn't really make a huge difference on whomever you are gifting it to. It's just something worth noting before anyone orders it. Our Daughter couldn't be happier, having received this as a present. We already had the Book of Bill, and this one is a welcome addition to her home library.

Gravity Falls Fans, Your Time Has Come With This Excellent Book
Format: Hardcover
'Gravity Falls' was one of the best animated series to be created on the Disney Channel, where the majority of shows are trash IMO. The humor, voice acting, writing, animation and mythology were all perfect. Very much like a kids version of The X-Files, but not dumbed down and still very adult in many ways. Dipper's Journal 3 was something I've always desired to see become an actual bookshelf tome and now fans, like myself, have it in this extremely awesome book. All the pages shown throughout the series are there, as well as those that were never seen or hinted at, and a large section supposedly added by Dipper and Mabel. One of the best features that caught me by surprise were the front and rear covers. Normally, a book with a dust jacket like this has a neutral plain one color cover to it under the removable jacket. Not this baby! It looks just like the jacket, just without the logos. Really, you don't even need the jacket, but it does protect the beauty of the real covers. Even better, the publisher went a step further by adding a treat to fans on the inside of the dust jacket. Blueprint forms of the Memory Gun, Gideonbot, The Portal, Laptop and Sea Monster submersible. I never expected that since 98% of them are just white on the inside. Another wonderful addition is the sewn in cloth bookmark. You know a hardcover is well made when they have one of these. Shows the publisher spent time to make it worth having and enjoying. I'm not going to talk about the interior pages, since they are all fantastic. Just get the book and have a great time with it. Now, there are two things missing that should have been included, and technically would have dropped my rating to four stars, but the book is still five nonetheless. It is missing a cryptogram decoder page and a foldout poster of the full Bill Cipher cryptogram map Dipper and Mabel had to put together using all three journals. There is a decoder on-line, but having it in the book should have been a no-brainer addition since every page has codes to decipher. Writing wise, the only minor thing that bugs me is with the misuse of commas, or the lack of, where they should be at times. For example, when describing three things - blue, red and green - Rob Renzetti has a tendency to do like a LOT of people have started up over the last decade or so in putting a comma after the second word 'red' when it doesn't belong there. Yes, I'm being a grammar nitpick, but it really gets annoying after awhile. These elements are minor and the amount of excellent artwork and information contained within the book make up for missing items and writing issues. It's a shame the 'Special Limited Edition' version with blacklight ink pages, removable images/notes and a magnifying glass is so extremely expensive. Instead of two books, there should have been just one with all of the goodies. This is a must have for all Gravity Falls fans. Don't miss it.
