I am having the same problem. I have the nautilus 88 key. I have had the keyboard new since oct 2021.
I usually play program A000, nautilus Grand , and get the drop out quite frequently. I think it is getting worse with time.

Today after booting up and playing it happened a few times over about 10 minutes. I recalled seeing something like this in the korg forum, so checked this forum and found the problem is exactly as seen/heard in another post .

So I tried program A001 and A002 for what seemed liike more than enough time for the problem to happen again and it did not.
I went back to A000 and the problem happned again right away.

In the mean time.... I have seen the previous message saying that the SSD had to be replaced. how do I verify if this is the problem I am having?
Is there a way to test the integrity of the SSD? It was my understanding that when an SSD failed it failed suddenly and totally.

There are several software tools for that but the SSD needs to be tested externally. So you would first need to remove it from your Nautilus and there are basic precautions to take to avoid damaging the SSD from things like ESD, etc. Also, there are different types of faults which can occur. For example, I've once seen a damaged SSD still working but as if it were ROM - nothing could be written on it anymore even though only half filled. The CrystalDisk test software was showing impossibly high write speeds, which basically means : SSD kaput.

Korg advised to reinstall the OS. I was able to re-install the initial factory OS. But this created a different problem. After a few seconds to a few minutes of playing the keyboard goes completely silent - no sound from any sound engines. A reboot restores the audio but keyboard goes silent again shortly thereafter. My keyboard is at the shop for warranty repair.

After the problem happening several times yesterday, I decieded to try to record a video and send it to korg support.

After 45 minutes or so of playing and recording video, the problem did not get recorded.
The camera records for 20 minutes then stops, so it took more than one recording over 45 minutes. And wouldn't you know it... once, after the camera finished one of it's 20 minutes recordings and stopped.... the problem happend briefly for about 2 seconds.
And I could not get it to happen again.

The solution to this problem seems to be to point a video recording device at the keyboard and record.....

Sorry, I am going to blow a gasket, just letting off steam.
I will get that recording and I WILL get it to Korg.

Hi tepa59,

did it help to replace the Nautilus? I have the same problem and am considering sending the unit in for repair.

Thanks,

It's not a specific sound issue, nor is it a specific key issue. It also occurs when I'm not using the damper pedal. Nevertheless, I have already tried several pedals. I controlled the Nautilus via an external keyboard via Midi, the problem persists. Oddly enough, it always occurs when I haven't played anything for a few minutes, everything is usually back to normal after a few seconds, and if I then play without interruption, nothing happens anymore. Maybe someone has experienced something similar, at Korg they couldn't explain the problem themselves. I currently need the Nautilus every day and won't be able to give it to a workshop for two months...
After the problem with my Nautilus could not be solved by Korg, I contacted Korg support again today and received the following answer: "Currently it can be assumed that compared to the Nautilus models sold worldwide these are isolated cases in which the temporary phenomenon you describe occurs. According to new findings that we have, the cause of the affected instruments is probably due to a tolerance in the built-in SSD module. Since this complaint is a repeat case, we advocate an exchange of the device so that you can have access to a technically error-free instrument as quickly as possible." So I will get a new Nautilus and hopefully have no more problems...

Is it difficult if you open the back cover of the Korg Nautilus?

Is this a problem with every Korg Nautilus?

I emailed korg. I wish I could find the email and the response...
They told me to update to the newest firmware.
After the update, The problem seems to be happening less. But I HAVE heard it happen since on 3 occasions. It happened 5 minutes ago.
I have been trying to capture it on video, but so far every time it happens the camera is not running. And today was no exception. The new firmware update does NOT fix the issue, but it is not happeneing as much as it used to.
It should NOT be happening at all!!!

Hi,
As a Nautilus 88 owner who has not had this problem occur so far, my question is can I find out what SSD is installed in my Nautilus without opening it up (something I would not like to do). Can the SSD make and model details be seen on the screen ?

Hi

Brand name is Buffalo SSD . It's very low quality

Best regards

Hi Mehran, thanks for the reply but unfortunately it does not answer my question. I need to know if you can find out what make & model the SSD is by going through the screen menus. I bought my Nautilus 88 as a used model so I'm not sure if the previous owner changed the SSD.

I don't know because I don't have nautilus. I have just pa5x 76

I decide to buy nautilus 73 too

My Nautilus 88 is back in the repair shop for the 2nd time in 2 months. No Audio output fault condition. It can be triggered is several different ways. I was fortunate to capture the fault on video. The repair center is going back and forth with Korg to determine what to replace.They are trying to decide between the motherboard, CPU board, or RAM board. Gotta wonder if Kronos had these types of problems when initially released. Also, very curious how similar/dissimilar the Nautilus hardware architecture is to the Kronos architecture.

Back on topic, anybody find after the latest OS update that the cut-off issues are corrected?
