Solar flares?

Hi Dan, missed your earlier post. It's an unmodified production KRONOS 61. The sound files I posted above were captured running the production OS 2.1 off the internal drive; although the problem I experienced yesterday (which sounded similar but more pronounced) happened when booted off of an external dev drive running 3.0. I wasn't able to record that one before it somehow went away. Usually I have to reboot when I have experienced this.

Do you have two KRONOS instruments? The one with the external boot disk is at least slightly modified.

It's not modified at all. You can ask Bill about it. I don't see the need to go into details about how all this works on a public forum. But when I'm running off the internal drive, it's totally stock.

You've already gone into plenty of detail. No need to ask Bill; I'm aware of the various ways that this can be done. If you can run off of an external drive, it's rather obviously not just a stock KRONOS - since stock KRONOS don't have external SATA cables. Hence an enhanced possibility for hardware issues.

Dan, I understand your line of reasoning, and no one really knows what it is, so anything's possible, but the chances of what you are saying are pretty slim

The sound on my iPad disappears regularly in some apps, my MacBookpro (older model) crashes few times a week.
So compared to that, and being that K has a lot of PC-like hardware inside, I honestly think that Kronos is amazingly stable. No sarcasm here, I do think it's great.
Well, glitches happen, and the purpose of this thread was to share information, not to put bad light on the product

There are no external SATA cables. It boots off of USB, using the standard USB ports in the back. Maybe you *should* ask Bill.

At the most, the only thing modified in this Kronos would be a BIOS setting to allow booting off of an external drive, if that was even necessary. No hardware modifications. So I don't think you can discredit the experience I've described here by saying "it's a modified Kronos". Anyway, I was merely answering the original poster, who has the same issue, and does not have a modified Kronos. Yes, I have experienced the same issue. Yes, it does exist. Yes, I have an APC UPS tower protecting my gear. Yes, here is a recording of the problem. Does it mean a pending hardware problem or a software problem? Who knows?

kronos-good.mp3 (a snippet of a KARMA combi that sounds "normal")

kronos-bad.mp3 (the same combi when the Kronos started making weird digital noise. I had to reboot).

I have noticed after extended uptime (like a week) the Kronos can get a little "Wonky" at times. Generally random abnormal behaviors, functions stop working (but not full system crash), though not distorted sound enough to remember. Reboot always cures it and never an issue at a gig.

so you leave your Kronos powered up for a week ?
I don't have an opinion about that.

curious if after 4 years of ownership, what is the wear factor on components if left on like that

Other than potential screen burn-in, computers in general are designed to have a very high duty cycle. Fortunately the mobo on this sucker is a computer, so I would anticipate that it would be just fine to leave it on.

I'd sooner be worried about something burning in the screen but maybe it's not a problem with that screen type?

Thanks for that.

Possibly you have spotted it. Back in the day, I recall the Triton LCD had some potential of burn in. whether or not this applies to the Kronos is only speculation ( in context to leaving the Kronos on a great deal).

I thought I remember seeing one in a music store that had burn-in bad enough that you could see it when the screen was off. (It was in combi mode most of the time it looked like) but those are those floor models that was on for 12 hours a day for months and months... Who knows how long it was there though is the other thing too. Could have been a used model that was always-on in the studio too right? Who knows the background.

Anyway, I've only ever seen it once, and I don't know the scenario surrounding it. That said, mine is serial number 000128 and has LOTS of usage and has 0 issues whatsoever. *shrugs*

After looking at all your posts I feel that maybe the Kronos CPU overloads and rebooting clears the issue! It depends on processor , ram or hard disk I'm not 100% clear but this might be a factor.
because in small power processors in PC's have similar issues and restarting clears up the hitches. Kronos is a very costly piece of equipment and it shouldn't have this type of glitches

I have been getting odd behaviour with a patch called "Crystal Clear 2" which is just a simple Poly 6 one that came with the original Kronos.

If I hold a key for a few seconds (this works with and without the effects switched on) the sound turns into a load of phased rumblings. If you play the patch for a few notes every now and then all notes turn into noise.

I cant see if this is due to lots of voices sounding at the same time, does not seem to be, or the effects processor overloading.

(It might just be this patch)??

Mine has been on every single day, 24/7, going on 4 years now. A few spontaneus resets on earlier OS was all I experienced On/Off stress takes it's toll too (huge temperature delta) and been for ages asking for a standby/wakeonevent instant-boot feature.

Had this sample sync problem a couple times, sounding robotic, went away with reboot. Seems like a software glitch.
