And you didn't take any pictures to share with the rest of the class? I'm curious what the internals look like as I am unable to locate any images online. Guessing it would be very similar to the Kronos, right?

Here are the pictures I've taken.

Yeah, I don't know any specifics but it could very well be that Korg had the KDM made to their specs. When you compare the KDM to other 140s, you see a number of headers, ports, etc. missing. The only visible port is a VGA. But many headers don't exist and are just solder points. Korg's propriety circuit boards all start with KLM. KDM, which is obviously close to that, might be a coincidence or might point to a board designed specifically for Korg.

Today I opened up my Nautilus and removed the motherboard. I can confirm that the SSD is indeed a removable one with standard m-sata interface. Curiously, my Nautilus comes with a Buffalo branded SSD which I cannot find anywhere online.

I checked the layout of the motherboard and compared it to Asrock IMB-140D Plus, it seems that all the components are identical, with the exception that some IO ports and one RAM slot are not missing with bare solder pads.

Hardware wise the Nautilus has a single DIMM of 4G DDR3 RAM, and it seems like everything is attached to the motherboard via two internal USB ports, including the keyboard, touch screen, front panel buttons, joystick and rear audio/MIDI/USB ports. My guess is that one of the usb ports directly connect to the rear USB A port, and all the rests are attached via the Korg custom daughterboard.

Looking at the hardware, I believe there're huge opportunities for custom upgrade. A few years back, (Software Piracy Do Not Click)_ and Marcan have upgraded the motherboard and CPU of their Kronos keyboards. In order to make the Korg software work with the new hardware, they have to do quite a bit of software patching. However, compared to the Kronos, the Nautilus is an even more standard x86 platform with every Korg proprietary hardware attached via the USB ports. This design opens up the opportunity of replacing the motherboard and running the entire Nautilus software in a virtual machine. As long as the hypervisor can emulate the USB controller in the Intel NM10 chipset, we might be able to run the Nautilus system without any modification at all.

Of course, the first thing I've done after opening up my Nautilus is to image the SSD. Now that I have the system image I'll try to see if I can boot it in a VM.

We really have to follow up on this idea of emulating, in the end we would have a simple USB connection to connect to our computer which, through a virtual machine, would surely start the Nautilus 10 times faster (25 seconds), not to mention the storage, but overall apart from starting and storing if we do not go into the code to compile the Nautilus system in 64 bits,

What do you think ?

It would also be necessary to be able to increase the polyphony and the number of audio and mid tracks. Have 128 midi tracks for example

So, looked over this older thread. Simple question. So is the computer technology and hardware in the Nautilus Any different, updated, or more reliable than the hardware that was used in the Kronos 2? In other words, is there any reason to believe it would not have the freezing and errors that are evidenced in the Kronos machines now?

Nautilus, more reliable than the K2 ? No. I have read more complaints since it's out compared to the K2 initial years. Piano sounds that suddenly stop on a brand new unit, screen lagging, etc.

Worse thing I noticed and don't like at all is where Korg put the mSATA SSD under the MOBO. Far from brilliant, if not a terrible design flaw. It is a perfect place to make it overheat and switch to turtle mode. Tiny M.2, mPCI-E and mSATA drives run quite hot and need at least decent ventilation or a heat sink. The K2 instead uses a 2,5'' SSD positioned to receive at least some ventilation instead of being completely buried.

I learned this from experience with my "small-factor" new i7 PC. The stock M.2 had a meltdown after less than a year, because it had no heat sink nor nearby fan to bring at least some ventilation. First thing I would do if I ever must buy a Nautilus would be to fix that problem as soon as the warranty would expire or even before.

To be fair, we're talking about an Intel Atom CPU from 2011. It's not going to make that SSD work hard enough to overheat. I think they did it to keep people from replacing the SSD because they blamed customers looking under the hood for all the issues. Most of us wouldn't go under the hood if we didn't have a reason to to begin with.

The Nautilus runs much cooler than the Kronos 2 (around 38º-39º) and is very quiet.

Regarding the note stoppage and screen freezing, that this was all resolved with the latest software update (1.3.3)?

Also, aside from the SSD new placement, it sounds like the basic motherboard "vintage" and tech design is unchanged from the Kronos.... about 2011 technology. I thought that would be the case.
