Resurrecting an older thread...wondering if the folks that rolled back stayed or updated their firmware to 2.00?
Since I am relatively new to the Variax thing (Oct 2012) I don't really at this point see a need to rollback, so can anyone tell me WHY I might want to?
If the v2.0 firmware is working fine for you then there is no reason to roll back.
If you have never had experience with the pre-v2.0 releases then there is no comparison issue for you, so again, no reason to roll back, unless you are inquisitive and want to see for yourself what the pre-HD models sounded like, but be aware that the reflash process does not always go smoothly so if you try it ensure you do everything as recommended to minimise any risk of the operation fialing and having to be repeated numerous times.
If the v2.0 firmware has introduced a condition that you can't live with then you may want to roll back to a version without that condition. eg: for me it has introduced a loud popping noise when connected via VDI to HD500 and changing between patches that also force a model change on the JTV, this is not good for live use when changing patches mid song, so that has caused me to roll back to v1.9
For others, it has been the fact that you can no longer connect your JTV to workbench whilst connected to the HD500, you have to use the JTV USB dongle to connect to Workbench HD - that was loss of functionality which they considered important.
If you were accustomed to the model sounds from the earlier fw releases and had your live set tuned to those models, then the v2.0 models will cause you a problem because you will have to tweak everything to get back to something you like, and it may not be possible to reproduce exactly what you had because the actual model list has changed, some models have been replaced by other guitars with v2.0, plus well liked models like the Lester, Strat, Tele and Semi have been re-modelled possibly with different guitars and some now sound very different to the pre-v2.0 versions, so some people may try to tweak things to be more to their taste and may fail to get there, others may not want to be bothered, so to their ears the change has been "bad" and has not been an improvement as advertised and as expected by the HD association. Some people had favourite models that were lost in the upgrade, so they had to choose whether to move on without those models or roll back to keep them. For some, the new HD models were worth the sacrifice, but for others they were not. Some people loved the new sounds immediately, others had to tweak them to get what they wanted, and others were met with what they thought sounded like "bad" and inferior model sounds, so moved straight back.
I think if the HD model set was a straight replacement for the pre-existing model set, just moving to better quality more realistic models of exactly the same guitars, then less people would have had issues. But the change was a combination of improved models possibly using different guitars, and completely new models nobody had before and losing some of the previous models. Plus the actual installation of the fw is not always trouble free, even when following recommended instructions, so that puts people off immediately. Furthermore, there are known bugs that have still not been addressed.
Personally, I would like to move forward and stay on the latest and "greatest", but I have experienced the comparison "shock" in that the v2.0 HD models did not immediately live up to my expectations from hearing all the demo videos and in comparison to what I was accustomed to from my v1.71 model set, plus the confusion that the model list was not identical (not that I lost any favourite models, and not saying that some of the new models are not great additions to the selection, just that I had not realised it would be different), and I am frustrated by the inability to use Workbench HD when connected via my HD500, but the deal breaker was the fact that it introduced a loud popping sound when changing patches that forced model changes in the JTV from the HD500 when connected via VDI. I am now back on v1.9 and have an open ticket with Line 6 support for the problem. I am hoping they will address the issue, but given the fact that they have just been taken over by Yamaha, I am sure there are all sorts of things going off over there, and probably fixing bugs and releasing an update fw level is probably low on their list of priorities right now - which is a real shame.
Having said all of that, which I believe is a summary of all the issues I have seen reported, I am optimistic that these issues will be addressed in the fullness of time, I just wish they could fix them now!
