This week I'm playing a recurring festival and we're leaving our gear at the location. Yesterday I played, turned off my stuff and left. Today we went on stage and after starting my K88, all my setlists were gone?? Literally all of them, not just the latest one or the one I had been playing. They were all just empty showing the German Grand preset. Everything else seemed fine. Thankfully I had a USB stick with me to quickly load a recent PCG. I don't know if I lost anything but I had no choice because we had only two minutes before we actually had to start the show. I didn't even want to risk reboot time.

Has anybody ever had this? Is there anything specific that might cause it or something I could do to prevent it? Not looking forward to more pre-show stress, I play every day until Sunday this week, and twice on Fri and Sat.

This is really weird... maybe the preload.pcg got loaded or something similar... Anyway, your best bet is to always have a backup (or two) with a PCG including all your Programs, Combis and so on...

Need more specifics about your work flow- boot up and/or loading procedures. Best bet is to always back up data to external media.

I had the same problem, but in my case some of my combis disappeared as well. Very scary...

I always create folders for each project that I work with. also I so a "Save All" named for the same project in that folder. After boot up, I load all the data from the folder. whenever I am done making changes I do another "Save All".you sure to write all your changes especially your set lists, programs and combinations. be sure to back all this stuff on external media.

Ok first off, of course I have backups, I even mentioned loading one from USB. What I don't have is a backup from every single session, nor would I expect to have to make one.

There is nothing very extravagant about my loading procedures. I have Busch's clav and one bank of custom samples on autoload, that's it. I'm not even using the extra gb of RAM I have installed. I don't really see what else there is to know about booting up, as I said, I booted and they were gone.

Oh and no, it wasn't that the Preload got loaded by accident (which would be bizarre to begin with), because as I said my combis were all there and there were NO setlists, not the preload one either.

The only significant edit I did the last time it was on before the disappearance was to make a new setlist for that gig. I know for a fact that I saved that because I had to go back and forth between other setlists to copy and paste slots and if you don't save in between, your edited list is gone.

maybe backing up after every session would be a good idea. What I usually do is just copy the whole folder to a USB thumb drive.that is a quick and easy way to do it.

I backup stuff regularly to a USB drive. This is not a hard thing to, I know. But I don't accept that I should have to do this after every session because it would be somehow normal or acceptable to randomly lose stuff upon boot. Why would the K even have pcg memory if I had to save and load everything for every single session?

Moreover, thank you for the advice, but it doesn't actually address the issue - why did this happen?

why did it happen? Maybe some details about the festival might be in order. What kind of power were you on? was it an outdoor gig? were you on generators? ccould there have been a power spike it some point in time? Maybe even overnight? maybe you should disconnect the power from the Kronos just to make sure that no kind of spurious voltage spikes get in there.remember that the Kronos is a computer and we all know computers have a tendency to act up from time to time. And you will never know when that's going to happen.

My Kronos was plugged into my UPS both times I was playing it, and unplugged completely while it was not.

I do appreciate your advice, and I really don't mean to sound aggressive, but it's a little annoying to read comments like "make a backup", "maybe the power was bad" and "computers will be computers" after something very unacceptable happened at a very inconvenient time. I do and did all the sensible stuff.

Please excuse my tone. But I was looking for something a little more specific on what kind of action might cause setlists to disappear, or if there is a simple trick to restoring them, or even if a reboot might have fixed it.

Sorry about your frustration. I realize you post on the forums a lot, helping others many times. I was just going through some of the standard troubleshooting. No one else seemed to be offering suggestions. Probably because a majority of the posters come here to get answers instead of offering them. As you very well know the Kronos is a deep, complex machine. Not sure that a recovery of lost data is possible. If I understand the technology correctly, like a computer, until the system boots up and loads data into RAM you basically have a boat anchor. So all your data in the form of PCGs, samples, etc is stored on the SSD. A glitch could make the data load improperly, if at all. In a corrupt HHD data can sometimes be restored, but it usually takes special software and knowledge. So I don't think the Kronos offers this option. Might be nice to see some Korg tech offer some insights. Other than my previous offerings, maybe checking that your physical RAM & SSD connections are solid would be in order. I've read posts that say this can cause issues. There could also be temperature issues that affect the motherboard. XBox 360 systems had problems caused by a motherboard that warped when it heated up. Sorry if this doesn't answer your question.

Surely you may not be waiting for a conclusive technical reason which caused your issue to actually happen. We're not the design development team. We weren't next to you watching what exactly you did. We have no video footage recorded with the previous hours of usage of your Kronos to better diagnose what happened.

So what we can tell you is that, considering the strange behaviour you got... well the most reasonable advice is to backup absolutely everything (which we understand you did, yes: we read your post and you say you don't know if you lost something or not with the backup). We clearly get it sounds like a pretty basic and stupid advice to you and so on, but it's the wisest thing you can do, considering you (and neither we) have any idea regarding what really happened. So your guess is as good as ours: nobody knows. But consider the positive result: you were able to recover from the issue and next time, you'll be better prepared to better deal with such issues.

Anyway, to give you some other answers, maybe you executed the Page Menu Command called Initialize Set List which will set all your slots to Program A000 which is the German Grand... Sounds like the result you got (except for the fact it happened on all your Set Lists). I don't think you're the type of user which would do something like that, but it must be considered

Thinking 'Totally Out Of The Box' there have been quite a few solar flares recently that could possibly cause a problem. In the past, I have plugged a thumb drive into a workstation, only to find NOTHING was on that drive! No explanation, but I completely get your frustration.

Hi there SanderXpander,

Yes it has happened to me once. I could probably find my original post about it, too. But that was before the very first update. Never happened since. It has happen to someone else here also about 5-6 months ago, I remember reading about it.

You're lucky you had a backup. I didn't at the time, I was learning the Kronos and it never crossed my mind I could loose everthing for no apparent reason. Lost about 10 hours of work.

I also still loose customized sound once in a while. I was working on a program a couple weeks ago and I'm 95% sure I saved it, I always do. It's a second nature now.

Went back the next day and it was nowhere to be found. I find this extremly annoying because I don't make backup every single time I come up with something. I find it extremly confusing too because I can't be entirely sure I'm not to blame and that I should really be feeling like an idot for not saving it (when I know I did).

Make backup people.

I have thought I lost a patch before, only to find it later in a strange category. I have since taken to saving everything I modify as a "Favorite". Makes it easier to weed through the 1000s of available options.
