Readjusting everything after each Firmware Update ?

[RJKole]

Hello, i have learned that after Firmware updates patches may sound different to before and the user has to "readjust" them. Now i wonder if you guys went through this each time you made an Update (may be even with 1024 presets) ?

The only adjustments I've ever made have been to take advantage of new models or features. For instance I adjusted many presets when the new cab engine was introduced. I’ve never noticed any changes to the sound of existing presets, although I know that in some cases changes were made to specific models. 
 

With almost every new firmware release I hear reports from some people that they ‘feel like’ it sounds different for better or worse. I don’t believe I’ve ever seen a verifiable case.

FTFY.

You heard wrong.

Hi,

 

As noted above - you have not “learned”, but possibly you may have “heard”, on the interweb, about users having to “readjust” presets. Basic logic would seem to indicate that this would be a really dumb thing to do to a product with a firmware update. Quite simply it’s not a good business model to screw around with your user base presets who may rely on this hardware/audio for a living. 
 

I have owned a Helix from it was first released, with the original firmware, and done every firmware update since, (somewhere around 30) and never had any issues with “adjustments”. All updates are meant as improvements to the existing audio signal. In fact the main change was a major improvement to the Helix Core engine at Firmware 2.80 - everyone seemed to be happy with that, and even more so with the version 3.50 update to the Cabinets.

 

Your comment seems to indicate that you have only “learned” this, rather than actually experienced some sonic weirdness after an update which drove you to modifying all 1024 presets.

 

Unless you are one of those golden eared cork sniffer audiophiles - forget it!

Hope this helps/makes sense.

Aside from a few bugs that were known (for example the glitch delay behaving differently), all your presets should be exactly the same before/after each update.  I have 100's of presets and none of them sounded any different.  The only big change was the "oversampling" update introduced in firmware version 3.10.  I guess it technically is a sound difference, since it is an improvement to the overall sound--but not that you need to go and re-adjust anything.  It just sounded marginally better :) 

 

The only thing that could have changed is global settings.  But if you follow the firmware update procedure, you should always back up your Helix, upgrade, then reset to factory settings, and then restore from the backup.

Thanks everyone for your comments,

The reason for my post was that i kept having trouble updating my Helixes (i got two of them). I went from 2,92 to 3,71 a while ago and had serious sound issues (no global adjustments were made, at all, backups and Up/downgrades where all made carfully). I went back to 2,92 and everything was fine. Now a while later i got me a HX stomp and for maximum compatibility i updated all devices to 3,15 and guess what ! again some (IIRC Amps&Cabs) messed up the audio again. Aftergoing back and forward several times i ended up dragging every single patch manully into the corresponding slot. That was the only solution to get that sound back from my original 2,92 patches. I was able to immediatley hear the bad sound going away when dragging the single hlx tones over the ones i previously had restored from the 2.29 backups. 

I "heard" that this was quite normal when changes have been made to one or more models. Note: of course not every single patch was affected but enough to grow some grey hair. 

support: "The only thing that could happen if there's always the same amp or effects used in a preset and there was a change made, like a bugfix or optimization of a parameter. But this would be a special coincidence , not on a general scale

@RJKole

 

This may be a dumb question.  How did you go from 2.92 to 3.71?  I know I had to go up incrementally until I got to one of the early 3.xx version.  Also, once I got to 3.01 or 3.11 I would always backup, reset the helix to default, upgrade, restore from backup, allow the helix to update my patches, then proceed to the next update in order following the same procedure.  I know at some point there was place you could not bypass incremental firmware updates and a place where you could.  I just don't remember.  You can search the Helix history to determine the exact firmware version you can bypass.

 

However, my main question is did you go straight from 2.92 to 3.71 or did you do incremental updates and follow the backup-reset to default-restore-allow patches to update procedure?

 

Again, forgive me if you did follow the early update and backup-reset-restore-update procedures.

 

Thanks,

@jpdennis
Many official firmware update infos answer "can i go straight fromm xx to xx" with "yes". So i assumed going from 292 to 301 oder 315 as well as from 292 to 37 would only require the install of the corresponding HX Edit. Thats what i did, for 292->37 i installed the HX Edit that comes with the Firmware Download, before that i made my backup with the 292 HX Edit.
- Install HX Edit 37 - Factory Reset -> Restore everything from Backup 292. Same procedure with any other upgrade.

Hi, again.

 

I’m still slightly confused by some of this situation you describe.

 

Correct, the release notes do state that it is possible to go “straight from xx to xx”, but having said that, there was a huge change to the Helix Core at v2.80 which means that had to be installed correctly and reverting to any earlier versions would render unusable any presets built in the new version.
 

It appears you were updating from version 2.92 to 3.7 so, in theory, you should have been fine with that. Although, once again, I’m perplexed as to why you didn’t simply jump up to the very latest firmware 3.80 The Missing Link Update, which contains the very latest “bug fixes” and is recommended for all users.

 

This link provides the Line 6 Recommended Update process:-

https://kb.line6.com/updating-helix-hx

Lots of points to remember with this - such as using the latest version of HX Edit before starting the update, and closing any other software that may interfere with the installation, and finally, wait for all the presets to be rebuilt and then restore from backup.

 

When weird and unexpected things happen with your Helix, perform a factory reset, rebuild presets to bring them into line with the latest operating system, and if that fails, do a clean install of the latest firmware. Oh, and if you’re using a Mac, never let it lose focus of the HX Edit window during the installation which can screw things up, plus there is always the chance of “human error”. This is from someone who has had 10 years of essentially trouble free updates.

Hope this helps/makes sense.

Thanks for the update.  I did note that the information @datacommando shared with the link concerning the 3.00 update had issues with DSP with the upgraded poly blocks and compatibility with new presets once you brought in your 2.92 backup.  It was an implied, though not well stated, reason many of us rebuilt our patches during the initial 3.00 upgrade.  Then 3.01 addressed the bug for the audio corruption based upon certain specific block order.  It would be interesting since you say you are back at 2.92 to, remove all current poly blocks then upgrade only to 3.00, follow the procedure as you state you do.  After that upgrade to 3.01 and let the firmware do the rebuild which should address the audio corruption following the recommended upgrade procedures as you do.  3.15 talks about the cc remapping that tanked some of us.

 

We learned that hard way that while we could skip firmware updates we had to read all the warnings prior to that and accept the outcome.  So I suggest before you do anything, and it is just a suggestion, you read the link @datacommando shared specifically for the warnings with each firmware update starting at 3.00 and determine your best path to get to 3.8x

 

This is just my humble feedback.

@datacommando that 2.92 -> 3.7 update was done when 3.8 hasent existed yet .

@jpdennisthanks for the information, since i got (hope) my 2.92 presets now sound all ok with 3.15 and it took me almost a whole day to manuall drag the single presets over again like described above, i would not dare to try 3.8 now. I could not tell exactly under which circumstances sounds were broken (2.92->3.15) and i dont want to go through that fixing process again. I remember one (dont remenber which one) Amp/Cab was totally overdriven and either too low in output or too load, especially together with certain ODs and Dynamics, Clean Sounds were less affected IIRC, though high output guitars easily produced a distirtion were none was expected. (possibly input issue). The most interesting part was that i was able to fix that by dragging single presets over to the HX Edit (on top of the already rerstored ones !).
