My JTV59 is on fw2.0 and it makes a popping sound when my HD500 changes the model selected when I change patch using Fs1 to fs4.

I have tested the HD500 with a standard guitar and the patch changes are silent. I have also tested with the JTV and each patch set to DONT FORCE and its ok, but if the HD500 patch forces a model change then I get a popping sound when I press the Fs.

I will roll back my JTV to an earlier fw and see if the popping disappears, and if it does then hopefully I can identify which fw introduced it. I suspect it was v2 as I did not have this problem before.

This popping is particularly noticeable when connected up to my DT25 and also changing amp models, and at volume the popping is really clear and not what you want mid song or even between songs.

Has anyone else had this issue? Thanks.

Does it seem affected by which particular patches are involved?  I routinely use the HD-500 to switch, e.g. between six and twelve-string Rickenbacker models and don't recall ever hearing any artifacts.  Can you tell me what models you are switching between when this occurs?  I'll try it on my setup.

I am using TELE pos 1 and 5 and Lester 1.  But the problem is with any model change.   I know that from the very early days just manually switching banks on the Variax 700 and the JTV 59 would often result in a loud pop when moving to the acoustic bank - never found out why that was - but it never used to be a problem when auto switching from a POD floor unit such as the X3L or the HD500.  But with this latest fw release it is there.

 

I am going to rollback to 1.71 to see if it goes away and then roll forward and see if/when it reappears.

I have rolled back to 1.71 and the popping noise has gone.

 

I have a gig tonight so I have not got time today to roll forward to see when the popping will re-appear. That will have to wait till tomorrow.

What version fw are you on with your JTV59?    The problem does not occur at v1.71.     I will be rolling forward one version at a time to see when it reappears, because I jumped from v.171 to v2 and hit the problem.  I will have to stick with whatever the latest version is that is "pop" free for now.  Once I determine which level introduces the problem I will report it to L6 via support ticket.

OK - finally managed to find some time for this - then I realised I had to roll back to v2 before I could roll back to another level of fw - I should have rolled back one at a time until the popping vanished rather than go back to v1.71 and roll forward.

 

I had the SAME midi error failure at the end rolling forward to v2.0 - then I realised I had used my normal VDI cable so I swapped it out for the shorter cable that came with the JTV usb interface dongle and tried again. This time to my surprise when I had unplugged everything and reconnected it all, Monkey told me I had fw 2.0 on my guitar although it had just told me it had failed with the midi error - weird.  Anyway, I took advantage of the situation and selected the roll back option and chose 1.82 this time. (I know I should have tried the going back one at a time BUT I had made my mind up I was rolling forward one at a time).   Good news is that the popping does not occur at fw 1.82.

 

Now I have to try 1.9   so watch this space  ....    :)

I have now moved on to v1.9 and  I can report the popping is not happening.

 

I will stay on this for a little while before I venture to v2.0 again.  Perhaps the popping has been cured by the reflashing or it was introduced with v2.0, I won't know until I go back to v2.0.

HI - Line 6 have just responded saying "first they have heard of this" and "can I post a sound clip of the problem".

I pointed out that you are also experiencing the issue and that I had rolled back to avoid the issue and have some gigs coming up and won't have time to roll forward and back in the meantime.  I have asked if they can try to recreate it, as if it is a problem with fw v2.0, then it is easy to recreate and spot, and if not then it points to an issue with our JTVs or the way we updated our fw which caused us to have the problem.

 

If you still have a JTV that is exhibiting the problem - would you be able to make a quick recording showing the problem and post it to this thread?  I can then point Line 6 support to this.

 

Thanks very much.

First they have heard about it?

 

Is that direct confirmation that Line 6 don't bother with monitoring threads in this forum: http://line6.com/sup...e-variax-model/ ? edstar was on that one too back in August.

 

I also get a pop when changing Models via HD500 expecially going to Acoustics, won't be able to record anything until at least Sunday

If they don't know about this they are not playing their JTV's because they all seem to do it.  They should be more careful about this because it is important to folks that are playing live and switching models.  This is one of the coolest features of the JTV!  It's all about controlling the DC levels of the models I believe.  The Variax500 only did this  when first switching to the Acoustic bank.  It did not pop when switching to any other banks and it only popped once switching to acoustic.  I always found this to be annoying.

Thanks everyone for confirming that this is not isolated to just me and JeffersteinVS.   I have cross referenced both this thread and JeffersteinsVS's earlier thread in my support ticket and mentioned several people have confirmed they get this problem..  Hopefully Line6 will take notice and get it fixed.

They do seem to be very slow on bug fixes and updates for JTV lately:

 

WB HD bugs - discovered right after release.

 

No Pod Driver for WB HD (everyone is waiting for this one!)

I guess that is no surprise considering they have just been taken over by Yamaha - I guess all priorities are being re-evaluated as they get assimilated.  I hope it doesn't add too much of a delay to getting these items fixed.

Probably more about the new product (or products?) being launched at NAMM next week.

 

They are fueling speculation with little hints on the main website, about how they have "re-invented" guitar amplification. I expect that it has been taking up all their time for most of last year.

 

For some reason no speculation threads have taken off here, but this one is more active than most: http://www.thegearpa...d.php?t=1370086

 

I just hope that:

 

a) The Launch and Delivery are not disconnected like with the JTVs

 

B) That they have been bundling up the bug fixes and improvements for the other products with integration into whatever it is so that we get some fixes soon

Same here

 

JTV-69 (brand new) on 2.0, HD500 on 2.2, and popping noises, specially on patches with delay(s). I've rolled back the POD DH500 firmware, and popping seems to be less on previous versions, but still there!
