That’s normal default behaviour. Hitting the up/down switch is the first step in selecting a different preset. The flashing indicates that the displayed presets in the new Bank are available for selection. The ‘switch preset’ process isn’t complete until you have selected the new preset by pressing one of the A-D switches in the selected Bank. You can change this in Global Settings -> Footswitches using Knob 5 so that pressing the up/down buttons immediately loads the next preset or snapshot without displaying the flashing Bank queue. See manual pg. 68 for a full description.

The Vol pedal placement in the signal chain can have a dramatic effect on the tone. When placed before FX blocks such as distortion, or the amp, the pedal reacts similarly to the Vol knob on your guitar. Increasing the level means the FX/amp respond by increasing the amount of grit/crunch in the tone. Similarly, backing off the Vol pedal or guitar Vol knob cleans up the tone. When the Vol pedal is placed near the end of the signal chain it acts more like an overall volume control and increases the loudness without affecting the tone much if at all depending on what follows it in the chain.

Something obvious but you don’t specifically mention it….. Make sure you are using a Cab/Mic model along with the amp model. In other words, don’t just use the Helix Preamp models. Start by using a good pair of headphones and go from there. Once the tone sounds reasonable through headphones you can move on to tweaking with a PA system.

I expect this is a Global Settings issue. Updating the firmware causes the Global Settings to be reset to their default values. I don’t have an HX FX but I know that with my Helix Rack the firmware update procedure requires me to create a system backup before the firmware is updated. One of the items backed up is the Global Settings. You should be able to get your customized Global Settings back by restoring the backup file using HX Edit. Be careful to make a copy of any presets you have changed since the firmware update before restoring the backup.

You might also consider saving the amp model as a User Default or Favorite after tweaking all parameters to your liking, including Hum=0. Doing that will allow you to add the model to any preset with your preferred settings.

That behaviour means there are one or more corrupt presets on your Helix. You’ll need some very high level math to track it down. ;-) When you start the Helix and the presets start rebuilding you will see the display showing you the preset number(s) as they are being rebuilt. The total number of presets in the device is 8x128 = 1024. The preset numbering starts at 0 (Setlist 1, Bank 1, Preset A) and goes to 1023 (Setlist 8, Bank 32, Preset D). Any preset that is still being rebuilt is corrupt. So take note of the preset numbers being rebuilt and do the math to identify the specific presets that are corrupt. Use HX Edit to overwrite the corrupt presets with New Preset (after exporting the corrupt presets to a designated folder if you wish). Repeat this until the Helix starts up without having to rebuild any presets. Then, if you want, you can import the corrupt presets one at a time and recreate them manually from scratch. Overwrite them again before shutting down the Helix device. Another approach might be to make copies of each setlist using HX edit. Then do a factory reset and start importing the setlists one at a time. Restart the Helix twice after importing each setlist. The first restart may rebuild the presets if necessary: this is normal. However, if presets are rebuilt on the second startup that means there are corrupt presets in the setlist. Again, do the math and proceed as described above if you want to recover any of those presets.

Of course I don’t know exactly what videos or comments you’re speaking of but in general most effects have parameters. They’re not really additional effects attached to the main effect but they do allow you to add a lot of variety to the effect. Sometimes the parameters include panning options. This is quite common with delay FX. The HX Effects manual describes common FX a parameters on pages 23/24. That might be helpful for you. Also, just spend some time twiddling knobs with some stereo FX models, especially the delays, to get some idea of how things operate. Of course to hear any stereo you’ll need to use two speakers or headphones. You won’t hear any panning through a guitar amp.

Those models are Line 6 originals, meaning not based on any real world analog pedals.

This is not a Global Setting. You need to manage it on a preset basis.

Yes. You can reverse the Min/Max settings on the EXP pedal so that toe=0 and heel=100 (or whatever levels you wish). See manual pg 56 for details on controller assignments and parameter editing.

No. The HX stomp is a single-input processor. You can have parallel paths splitting the single input, but not dual paths with separate inputs.

Does the noise go away when you disconnect the USB?

What exactly is the feature/function that you would suggest on Ideascale? From your description the issue seems to be that the HX Stomp lacks the dual path option, and the associated DSP, that the Helix Floor has. The available DSP is a hard limit. What would you suggest that doesn’t involve more DSP? Bear in mind that the DSP required for any block is allocated at the time the block is added to the preset, and is not dynamically adjusted based on whether the block is on or off. Any suggestion that DSP be added, or that DSP be managed differently, is probably a non-starter.

You are using a mono cable in the FX Loop Send jack. Can you determine whether that signal is summed to mono or are you getting just one half of the stereo feed? If the former then that answers your question - you are already sending a summed-to-mono signal. If the latter you could try using a stereo-to-summed-mono cable in the Send jack.

I think @soundog has identified the most likely culprit. Take a close look at what is happening with the signal level as it enters the audio track in Cubase and SAVIhost. From what you describe the signal level is the same leaving your audio interface but is increased somehow before it hits Helix Native. That suggests there could be an input level control on the audio track in either Cubase or SAVIhost, or both, that is increasing the level in Cubase more than in SAVIhost.

If a mono signal bypasses the stereo block then I don’t see how it could be made stereo inside the bypassed block. It must remain mono. Same would be true if the signal entering the stereo block was stereo - it would remain stereo.

I suggest you open a support ticket.

It must be done preset by preset, but not command by command. There’s an Action knob on the Command Center page that will copy all commands from one preset to another. (manual pg 62 for details).

Try reinstalling the JTV-69 firmware. I don’t think the Helix device supports that; you’ll probably need to use Line 6 Monkey and the USB interface for the JTV.

Just to confirm…. You’re using the VDI connection? Also, please confirm that the 59 is working and the 69 is not when you simply swap the guitars while remaining on the same Helix patch, or quickly leave the patch and return immediately to it.

I’m not sure what blocks you have before the amp but there’s no point in using stereo blocks there. The amps as well as cab/IR are mono blocks so anything in stereo before those blocks is a waste of DSP.

Interesting question. I’m not sure but my instinct tells me that a bypassed FX block has no effect on routing. The bypassed signal remains mono or stereo depending on its nature as it enters the FX block. In other words your assumption I understand it is incorrect. My thinking is that if a block is bypassed the signal does not pass through it at all; hence the signal is the same after the block as it was before the block.

Contact Line 6 support. They will fix it for you.

Yes. Go to the Downloads page (see link at top of this page). Use the middle data field to select Variax Workbench in the Software category.
