Unless I'm missing something, Helix Native can't restore from a hardware Helix backup file (new backup feature in HX Edit 2.30 and above). It would be great to have this feature, as well as the ability to create an HX Edit compatible backup file from Helix Native. This would make it a lot easier to keep the hardware Helix in sync with the Native plug-in, especially if you use your DAW on a desktop as well as a laptop - keeping them all in sync gets harder. But having a single file to backup from one and restore to the other would make it a lot easier because there would just be one thing to backup and restore, and it would also keep the set-list order and IR list order intact. Sharing across devices would be a lot easier. I searched Ideascale and didn't find anything relevant, so I made this Ideascale request: https://line6.ideascale.com/a/idea-v2/918622 Please vote it up if this would be of interest to you.

hi guys first of all I'd like to let you know that I read all the threads I found about this same subject and didn't find the complete answers, so I decided to run some tests myself (like I did on the POD HD years ago) and to create a new thread with my results (I'm on FW 2.60 by the way) ok, I'll start from the end results, so that those who just need to have a quick answer can read it immediatly, then I'll give some deeper explanations the main point of this post is: the moment you create a split/merge routing configuration by dragging down a block you get a level change: after the merge block, with all bypassed fx: with split A/B and Y you get +3dB at the output sum with split crossover you get -3dB at the output sum BUT each path by itself gets attenuated by -3dB so if you use the split A/B to switch between sounds, each of those sounds is -3dB qiueter than the same fx/amp with the same settings in a non-splitted path the good news are that the level changes do not actually occur at the split, so the two paths are both an exact copy of the signal before the split, instead the change occurs at the merge block so the right solution is to act on the merge mixer faders --- why? and why those values? • well to answer, I need to clarify two things that I've read someone get wrong and mixed up in other threads 1) when you sum two identical signals in a circuit either analog or digital you get +6dB boost (voltage sum) 2) when you send a signal to a physical speaker and then send the same identical signal also to another identical speaker you get +3dB (acoustic power sum) this is math and physics, not an opinion now, this second point is one of the reasons why something called "pan law" exists: as we said, when you have a mono signal going to two speakers (so the pan knob on a mixer is at the center position) you get +3dB of sound pressure so mixer designers in some cases decided to pad the center position of the pan knob by -3dB, gradually returning to unity gain at the extremes (in some other cases they may use -2.5, -4.5 or -6dB: the actual effect of the pan law depends on the coherence/incoherence of the signals, on speaker placement, on listening conditions, and also on mixing taste I would say, so the designers have to make an assumption and take a plunge, I don't have time to enter into this now, sorry). • now back to the Helix: you have an empty "new preset" patch you have a signal going through path 1 (I used various sine waves and pink noise) you add a gain block at 0dB (if you want you can even bypass it) => nothing changes you drag the block down creating a double path => you get +3dB at the output sum so, what's going on? - the A/B or Y split duplicates the signal to two paths, so each of them carries the same identical signal which goes to a merge block mixer channel, then the two get summed together... so you should get +6dB, but... ... since the pans in the mixer have a -3dB pan law you only get +3dB - the crossover does not duplicate the signal but splits it in two frequency bands, if you sum those two filtered signals you get the exact same signal you had before, so no +6dB boost here, but there is still the pan law, so you get the -3dB - but, as I wrote before, each path by itself gets attenuated by -3dB because of the pan law, so if you use the split A/B to switch between sounds, each of those sounds is -3dB qiueter than the same fx/amp with the same settings in a non-splitted path • please note that these are not theories or speculations, I've tested and measured thoroughly every configuration and I'm sure the Helix routing works like that • all this behaviours occur identically to mono or stereo signals, remember that all the lines representing signal flow in the Helix display are always "double conductor cables" so either stereo or dual-mono (stereo = they carry two different signals; dual-mono = they carry two identical signals) this point could be deepened a lot but I don't have time for this now --- some other considerations: • if for example you open the pan pots of the merge mixer to the extreme L and R, the pan law attenuation does not apply and the level goes back to unity BUT this is not a solution, because if you run in stereo you only get the left from path 1A and the right from path 1B • I'd like to warn you of potential problems I found with the parameters inside the split blocks I) the split A/B "route to" parameter is a balance control, not a crossfader, so moving it to the left attenuates the signal going into B while not touching the signal going into A and viceversa; so it is appropriate to use that parameter to switch from A to B but not too much to find a mix of A with B for 3 reasons: 1- as I said you only have control over the attenuation of one of the two signals you are mixing 2- at center (even position) you have more level than any other position because the two signals are at full level, so the judgement on which is the best mix is compromised for psychoacoustic reasons 3- worst of all: if the blocks in the paths are amps or distortion boxes or compressors, as long as you are not in A100, "even" or B100 positions, you are sending an attenuated signal to one of them, changing its sound and not only its level II) the split Y "Balance A" and "Balance B" parameters (added in fw 2.10 so not covered in the manual) work like this: the stereo or dual mono signal goes into the split, it is duplicated to path A and B and on each of those you can control the balance between left and right, those balance control also have a pan law but different from the merge mixer block pans ! in this case it's unity at center and +3dB at sides ! (I think the reason for this is to avoid an attenuation to the splitted signals at default settings) so if for example you use 2 amps in the paths do not use these parameters or the two amps will receive a different level than if the balance is at center. --- • to finish I'll add two other Helix Routing measurements I found during my tests: - the pan block is actually a balance control with a pan law equal to that applied in the split Y block: at center it's at unity gain, going to the left attenuates the right up to minus infinite and adds +3dB to the left (and viceversa) - unlike the POD HD500 the fx sends / returns on the Helix are all at unity gain levels (+/-0.3dB), thanks Line 6 ! --- thanks for reading, I hope to have been helpful bye Lorenzo

That would definitely be the easiest way.

Call it cheating, but since my band uses backing tracks I just record the harmonies and leave out the whole mess :)

Hi, I’m with @PierM on this one - No Line 6 Product recognised by the Mac, yet fully functional on your Windows machine. That has to be a problem for an Apple tech, not Line 6. When screwy stuff just starts to happen, you have to ask yourself, “what changed?” My guess would be that your MB did an auto update to the System software while you weren’t looking. Hope this helps/makes sense.

Hi guys, yes I'm still here, rocking my beloved helix I'm really glad to have been helpful to you! thanks for your appreciation bye Lorenzo

Cory Churko is Shania's musical director / Lead guitar player.... he's also a Line 6 Helix user. He is very approachable if you reach out via facebook messenger with a question. He does use a Kemper for his amp profiles, the Helix is his effects and controller - however I'm 99.9% certain he knows how to dial it in solely on a Helix as well. Cory wasn't the player on that album... that would have been a combo of a dozen session men, and Mutt Lang himself - but Cory is meticulous at matching tones. He's also toured with Shania since her initial tours in the 90's... he knows those sounds inside out. Edit to add: Check out You Tube for his live cam footage of that song from Vegas and his incredible mind spinning solo that starts around 5:20...

WHY do people have to be rude?! Sounds like a personal problem to me.
