Yesterday I had an unexpected unpleasant problem  :( 

while I was creating a patch directly on my HD500 suddenly developed a distorted noise (a sort of wild feedback) that in a matter of seconds has gradually risen exponentially in volume to impressive levels, unfortunately I was using headphones and it was quite unpleasant and painful..
:blink:

 

the first thing that came to my mind was to take off the headphones and turn down the master volume of the HD500, but the volume had no effect at all, so while the headphones were continuing to fry I finally disconnected them, and I believe I saved them, at least I hope so, I don't know if they have suffered some damages, but at least it seems they still work ..

 

when this happened, the HD500 was connected to the PC, I was not using the HD500 Edit application, in practice the POD was working also as a PC audio interface, to eventually listen to audio tracks using the headphone output of the POD ..

 

in that unlucky moment, I was moving a delay in the chain to hear where I liked the most, and suddenly happened the shock, the headphones seemed gone mad .. :o

 

later, I moved the effect again, timorously I tried to reconnect the headphones and I could not hear anything, neither noise nor sound, and I thought: s.h.i.t! .. I burned my headphones or my POD!...  :angry:

 

.. but hopeful I tried to select the next stored patch, and then returned to the previous one, and everything was normal and running again.. :)

it was an unpleasant experience, it might be handy to know what was the cause

anyway if it were to happen to you, remember!!.. the first thing to do is: unplug the headphones!!.. ;)

if I remember correctly, I think I read about a similar problem in the past
in this forum, but I don't know if it was solved

There were people reporting this sort of problem somewhat early on, and it was acknowledged as a bug and dealt with in a firmware update. Are you running the latest firmware?

yes, I'm running the v2.20 firmware, after I flashed it (when it was released), I did also the usual following steps: global reset and pedal calibration

Were you using a patch you created yourself, or was it one you downloaded from Custom Tone? It could just be a corrupted patch.

it was a patch created by myself.. I don't have any patch downloaded from CustomTone or from somewhere else into my HD500.. and also when I flashed some months ago I didn't keep the old patches and I have not even loaded them after.. therefore the POD was completely fresh of firmware flashing, reset and calibrated..

 

since when the thing happened my POD was connected to my PC, I suspect that the issue could be related to the PC-HD500 driver (which is updated), or something else that has still to do with the interaction between the PC and the POD..  who knows?

yeah the same thing happened to me I am not sure what firmware I had at the time cause I rolled back. But I just inplugged the power right away and I was ok.  I am not sure if you have a Macbook pro, But thats what I was using (not running Edit or anything just practicing with backing tracks).  It was so painfully loud (I use headphones too)..  I haven't had a problem since (knock on wood).. Good luck though

thank you for sharing you experience!..

 

I don't have a Macbook pro, I'm using a PC laptop running an always updated XP sp3..

 

for the moment everything is working fine, just hope it does not happen again, at least I know what I have to do immediately in case of emergency..

thanks.. that's an other clue..

so untill now is still impossible to understand which could be the cause of that issue..

 

to katiekerry happened while was simply practicing with backing tracks..

to you NinoScholz happened at gig after some patch editings..

 

to me happened while I was both listening to audio tracks and editing my patch directly on my POD..

 

the mystery remains still unresolved..

 

the only consolation is that it seems to happen rarely

 

PS. Nino, please tell me, you were also connected to the computer when it happened to you at gig?

^^^ Hurghanico - nope, i dont think i've ever been connected to the computer when it happens. I rarely do connect like that. For me, i'm convinced that editing a patch after turning the pod on makes it more likely to happen - or even indirectly causes it. It's never happened if i don't edit a patch after turning on. 

 

I'd say overall it's happened maybe 4 times to me.. I normally have to turn off the unit. I think even switching patches may have worked at the gig incident to clear it up - can't remember.

 

But man is that an ungodly sound!!!! holy hell!!

yes, it's really horrible!.. seem like an elephant to which they stuck a nailed stick in the a.s.s, screaming for the pain that wants to get out from the speakers :o

 

but do you remember if it happened to you with a specific firmware version, or with more than one?

You should report this to Line 6, because even though you seem casual about it, many in the past when it started to happen complained about loosing hearing. Line 6 put it on a priority status, since it effects public health, and they released a firmware to specifically address it relatively fast.  Thanks very much for the Heads up.

I agree that Line 6 should study this because it can damage hearing and damage equipment - headphones, speakers, etc.  It sounds like a FW bug to me based on this post.

I'm with you all on this too. Had a noise like this out of the HD500 once early on in the game and man it was a really nasty loudness that came out my amp, wasn't using headphones. So what I've been doing is turning down the master volume when I make major changes to a patch and then turning it up slowly to make sure it doesn't blair me with unsuspecting nasty loud noise. I havn't had any bad noises lately using this method. I don't move fx positions around with the volume up anymore.

^^ you know what - "moving patches around" could very well be the more specific issue. When i edit a patch, i normally have to copy it to multiple banks, so it's likely i was doing this.

 

As for the firmware, it was the always the most recent version before this new minor update that just came out (still haven't done that one - my pod is sounding perfect right now, don't want to eff it up). I updated the pod when i first got it last year to the latest firmware right away, so it's always been on that one.

Hi, 

 

Is it possible for any of you to give specific steps to reproduce the sound? Is it a squeal? A digital noise? Or is the patch just very loud? 

 

Can I get system info from you all? Operating System and version? 

 

Have you tried connecting to different USB Ports? 
 
Are you using a USB hub? 
 
What driver version are you using? 
 
I'll check back in a few days for the info. If I can reproduce the issue I can send it up the ladder. 
 
Thanks, 
David

@ Line6david

 

Thanks for reply here too

 

I don't know what to do to reproduce that noise ..

 

I would not call it a digital noise, is more like a very strong distortion increasing in volume very quickly to abnormal levels..

 

the only thing I know is that the HD500 was connected via USB (no hub) to my PC laptop with Win XP sp3 already updated, I used it as an audio interface to listen on headphones some audio tracks, and at the same time I was editing a patch directly on the POD (HD Edit app not running), and in particular I was moving a delay FX ​​model from before to after the amp model ..

I didn't try to connect to another USB port, since from that time it has not happened again..

I have a USB hub connected to my PC but I never connect the HD500 on it, but directly in one of the free PC USB ports..

my PC-HD500 driver says v4.2.7.1 which I believe is the latest..

 

 

PS. another detail: my Variax 700 was connected to the HD500 by the VDI

I'm not sure what you mean with editing a patch after turning on the pod. It seems to me you can't edit a patch without turning on the pod first.

I had this experience recently myself with my POD HD500X (latest firmware and drivers). I don't remember exactly what I was doing at the time but if I hadn't thrown off my headphones I think I would have gone deaf!

The sound is hard to describe but it started soft and turned extremely loud very fast.

I

 

Meaning that if you just turn the pod on and don't do any patch editing at all, it will never happen. But if you turn the pod on, then edit or move patches, and start jamming then it can happen - in my experience.

 

Mine is always just hooked up to a power amp when this happens, no PC/USB involved. I'm guessing it can happen either way from other's posts. The sound could be described as a digital bomb. Kinda like ground loop hum at jet engine levels

 

I'm on Flash 2.10

Actually come to think of it I had just Edited the Tuning for the JTV59 through the HD500.  So I had altered the patch prior to it happening....

I'm wondering if there's another common factor here. Seems this only happens after editing a patch - that seems to be one common factor. Is everyone also connected to a Variax (original or JTV) via VDI? Has anyone had this happen without the VDI connection in use?

I wasn't using a VDI Connection. I had this noise happen going into front of a Spider Jam with a Single Coil Strat going into the guitar input. It's been a while and if I recall correctly I was moving a delay ( I'm sure it was at least a time based effect) around using HD500 Edit to just try out different positions when I heard this weird noise initially at the instant the I dragged the FX into position and then that awful sound that starts off loud only to get louder (which happens fast) that's when I just pulled the 1/4" cable out of the guitar input of the AMP and then unplugged the Pod and started over. I forgot what Version Firmware I was using it was while ago. This is when I made sure I turned down the Pod or Amps master volume before changes to FX positions. Just recently I've been going into a DT 50 Head with the L6 connection and was changing an FX position while volumes where up and I heard that initial noise but no bad loudness following it. That startled me so I put the AMP in Stanby to make changes to the FX position.

 

1/7 Update: I always use Monkey to update everything before I start. Also when this problem happened the first time (long time ago) I honestly thought I did something wrong from lack of experience but after quite some time with it now I don't think so.

 

I'm using a Vaio AR630E, Win 7, no USB hub, latest drivers, firmware, and software in all device: HD500, DT50 Head, Spider Jam.

 

Hope this doesn't mean the issue is rearing its ugly head again.

I wasn't connected to a Variax. I was connected to the computer with USB.

I also had it once during rehearsal, connected to my Dt25 with L6 Link, no computer. 

I'm not sure if I had edited the patch then

This sounds similar to what was happening a couple years back.  Here's a link to a discussion on the gear page talking about Line 6 announcement about a firmware update that addresses the issue:  http://www.thegearpa.../t-1033652.html  This never happened to me specifically but if I remember right, people having the issue were plugged in via USB to their computer.  Hope this doesn't mean the issue is rearing its ugly head again.

Hello, all. We are investigating this issue, but we cannot reproduce it thus far. We're looking for more data from those who have experienced the issue recently:

· If the HD500 or HD500X was connected to a PC or Mac through USB at the time of a noise event, did their computer crash (as with a blue screen), and/or did the POD reboot itself?

· If moving a delay block preceded the event, exactly what kind of delay block?
· Were delay trails (page 1 of settings) turned on or off when the event occurred?
· Was audio being passed through the POD from a connected guitar (through VDI or ¼” guitar input) at the time of the noise event?
· Was a loop being played back at the time of the event?
· If audio was being streamed from PC or Mac at the time of the event, what app was it being streamed from?
· If a Variax was connected at the time, what firmware was loaded on it?

Since we haven’t observed this here yet, a snapshot of the other settings pages, such as inputs and outputs, might be helpful. Lastly, it might be useful if you could send the exact patch that was loaded at the time you observed the issue. Thanks!

...We're looking for more data from those who have experienced the issue recently:..

 

Hello Tony

the following are the data relating to me:

at the time of the noise event:
- the HD500 was connected to the PC, the computer didn't crashed and the HD500 didn't reboot itself..
- I was moving exactly the analog echo model from before to after the amp block in pre position..
- the delay trails was turned on..
- my Variax 700 was connected through VDI, no other instruments were connected to the POD, and I was listening with my headphones..
- I wasn't using the looper..
- the audio from the connected PC was being streamed using the standard windows media player..
- my Variax 700 was running the latest released firmware v3.10

I attached here the snapshots of the general system settings and the patch done by me on which I was working directly on my POD (no HD Edit running) in that moment

hope it helps

Boy I hope an event like these never happens to me.  I already have tinnitus from working on and around jet engines!  I'd hate to sell my POD, but if that happens I would in a heartbeat. :(

The same thing happened to me on 1/13/14 as described by the OP, except I was not connected to my computer, and I had not recently edited any patches.  Headphones were plugged directly into the HD 500, which is running firmware v2.2.  The volume swell that occured after switching patches was rediculously loud and damaged some nice Shure headphones.  The same type of volume swell happended several times on my HD 500 with earlier firmware versions, but not previously with v2.2. I opened a support ticket the day it happened, but Line6 has not yet reponded. This really is a potentially dangerous issue they need to promptly address.

I would like to chime in here. I had the same thing happen to me. Opened a ticket, went back and forth with line 6. They even replaced my HD500. It happened on the replacement too. What I had come up with, no help from Line 6. It had to be a preset I had made. Eventually I made other presets to replace older presets, and it hasn't happened in a long time. If you can, rewrite any presets you might think is causing the problem. Don't copy past anything. Make a duplicate from scratch. Also, reset the HD500 and do a peddle calibration. That seem to help to

thanks for sharing your case with this issue..

I tend to believe that this particular problem doesn't depend on old imported patches, since in my case I didn't import any one from when I updated the firmware..

also it seems that it doesn't depend on an active computer connection, since to some people happened when disconnected..

till now, one common factor seems to be if you did some patch editing, manually or with the Editor..

OK, all good points. Your last line " one common factor seems to be if you did some patch editing, manually or with the Editor " is what leads me to think it is the EDITING, manually or with the editor that is the difference. Because it happens when your connected to a computer or not, tells me it is not the connection that's the problem. Once the patch is made and stored on the HD500 it is what triggers the problem. The one thing that is different from when you first turned the unit on to when the Loud feedback like sound happens is that patches have been changed. Some type of effect combination or the patch becomes corrupted maybe. Because the patch can be saved to a computer, they are Windows base file format. And windows files become corrupt every now and then. I total think it is a patch that have been made.

admitted that a corrupted patch could be the cause of this issue, in my case the patch I was working on, (when I had the unlucky loud noise event) was never saved to the PC nor loaded from, it was created from scratch directly on my POD, therefore there wasn't any data format changing, if something has become corrupt, it happened inside the POD..

 

probably there is something in the Editing processing mode that needs to be fixed

For me this problem has only happened twice, once with an early firmware and once with the latest. Seems to me its an intermittent problem which usually are hard to pinpoint. Keeping in mind I do not gig with it meaning my HD 500 doesn't very hard service frequently. Although I will use it all day long sometimes hooked to my computer editing and saving patches while playing and recording through USB. Most of the time I have a great time using it.

I mostly play at home  and am always having fun learning how to play guitar so when I post a reply to try and help give ideas you know where I'm coming from. Rock-On!! Oh, and if I don't respond promptly I'm probably playing guitar or my computer locked up from multitasking 'cause I'm using Gear Box, HD500 Edit, Audacity and tab filled browsers all at the same time, Hahahaaaa. Surprisingly enough my 'puter handles the load more times than not. Lastly I'm not a salesman, I'm not trying to sell anyone anything here.

For me, there is no pattern that I could see and I have been working with this since I got the unite. To the point, my HD500 was replaced.
Here are some things I have noticed that may or may not have anything to do with it. I have a patch that has foot switch 1,2,3,and 4 that turns off and on effects. With the HD500 connected to the editor, I turn off any one of the foot switches. Close the editor, and turn off the HD500. When I turn the HD500 back on, the foot switch I turned off is still off. It should have gone back to it's normal setting with the foot switch on. If you change a patch in any way (not connected to a computer). With foot switches or any other change. Then switch to another patch then go back to that patch. It reverts to it's original state.
Also, open the editor with no HD500 connected. A message window opens, telling you there is no HD500 connected and the editor will run off line. Make a patch with two amp and as many effects as possible (exceed the DSP). Save it to your desk top (it will save it). Then connect your HD500 to the computer and open the editor. Drag the patch you made into the editor that the HD500 is not set to. Meaning, drag it to 4A, and the HD500 is on 3A. It will load, and work at first. I did this, used the patch all day. Came back the next day and it would let me use it, because the DSP was too much. Like I said, may or may not have anything to do with anything. The point is, this kind of stuff should not happen. You do the math.

Then switch to another patch then go back to that patch. It reverts to it's original state.

 

that above here is a normal behaviour..

 

when you load any patch you are using and eventually editing only a copy of that patch in a special temporary memory buffer..

the original memory slot is preserved, and changed only if you specifically save the patch into that slot..

 

every time you turn on your POD it works automatically with the edit buffer memory and the settings that were and are still in there.. that buffer memory automatically memorizes every last action you did with your POD: on/off state, knob settings etc.. from when you loaded the last patch..

 

the only way to change the edit buffer memory is to load another patch (or even the same patch number again), or doing some editings

 

so, in few word you are always using the edit buffer memory and not the original saved data, even if you are still seeing the memory slot bank number/patch letter from where the data came from..

 

Also, open the editor with no HD500 connected. A message window opens, telling you there is no HD500 connected and the editor will run off line. Make a patch with two amp and as many effects as possible (exceed the DSP). Save it to your desk top (it will save it). Then connect your HD500 to the computer and open the editor. Drag the patch you made into the editor that the HD500 is not set to. Meaning, drag it to 4A, and the HD500 is on 3A. It will load, and work at first. I did this, used the patch all day. Came back the next day and it would let me use it, because the DSP was too much. Like I said, may or may not have anything to do with anything. The point is, this kind of stuff should not happen. You do the math.

 

for the other issue above, I believe that the edit program when in off-line mode doesn't sense the hardware limits of the POD, and for that reason it lets you do patches more DSP expensive than normally possible for the HD..

even if you can send them temporarily in your POD, I don't believe that they'll be full working..

anyway this discrepancy is something that needs to be fixed..
