Schmalle

Set Global Settings > Footswitches > Stomp Mode to 6 Switch. Use Stomp Mode. Program the three footswitches by assigning each with a Snapshot Command (1, 2, 3) using Command Center. This has to be done per patch.

"Center" is 0%. Tip: Save the block as favorite for easy access and name it "FlipFlopper" or something even funnier. ;) Have fun.

To invert the phase set up a Stereo Width block [Volume/Pan (Stereo)] like this: Width Center, LR Swap Off, Balance R100, Level 0.0dB, RPolarity Invert ...and use a (any) mono block after it. Why do I need a mono block after it you ask? With the above mentioned setting the inverted signal leaves the block on the right channel only (left muted). A mono block after it automatically sums L (no signal) and R (flipped phase signal).

A suggestion would be to use a MIDI monitoring program to track all MIDI messages. Maybe that reveals something suspicious.

A total noob with a cave of forgotten gear? Find the error.

If you haven't been successful yet: start with using Helix in the loop. guitar -> VH4 input VH4 send -> Helix in Helix out -> VH4 parallel return Engage Send 2 button on the front panel and set the "Volume Parallel Loop" knob to noon. In Helix create an empty patch, select a reverb block and set it's Mix parameter to 100%. Crank Helix's VOLUME knob. You should now hear your VH4 sound with reverb and you should be able to dial in the amount with Vh4's "Volume Parallel Loop" knob.

You can contact support. I asked for the specifics of a different part which they provided.

Of those four links listed Electronic Music Services looks the best to me. The two guys doing repairs of music electronics for a long time and have great reputation according to their reviews on Google.

It sounds like you're having a very frustrating experience! Here is a rewritten version of your issue that is clearer and easier for others to understand: Line 6 Helix Floor Connection Issues with HX Edit I'm having persistent connection issues with my Line 6 Helix Floor and the HX Edit software on both Mac and Windows operating systems. The main problem is that the Helix will not reliably connect to HX Edit via USB. I've tried multiple USB cables, including another known-good cable, but the issue persists. When a connection is established, it is unstable. It typically stays connected for only a few minutes before disconnecting. This connecting/disconnecting cycle repeats several times. Glitching and Freezing: While it is briefly connected, the Helix Floor unit itself (and likely the HX Edit display) will start glitching and freezing. I'm unable to resolve this and I've already tried to open a support ticket with Line 6, but the system is not allowing me to submit it. Is that a fair rewrite? Concerning the support ticket problem, how did you realize that the system doesn't allow to submit it? Could you tell what specific Mac and Windows operating systems you are using (e.g., macOS Sonoma, Windows 11) and what troubleshooting steps you've already taken (besides changing the cable)? This information might help in suggesting a solution.

Does this occur without connecting to your Mac?

Make sure to set Global Settings > Preferences > EXP 2/EXT AMP to EXT AMP.

Not enough information. Listen to that track and / or take a look at the Helix patch that was used.

(answer to the OP) On my Stomp one foot switch's touch function was defective. It was a faulty TVS diode (GG040205170N2P) on the foot switch board. Because it's a tiny smd part (0.6 mm x 1.0 mm) it's not easy to replace it using a soldering iron. With a heat gun and some soldering paste it's easier. You can also order a replacement foot switch board from one of the Service Centers.

Think of paths as stereo cables. They can carry stereo signals (different signals on L and R) or dual mono signals (same signal on L and R). Stereo blocks are stereo in and stereo out. Mono blocks mix both input channels, process it and provide a dual mono signal on their output. Legacy blocks vary in behavior and can be mono or stereo or mono in / stereo out. The mixer block is where you decide how the path signals are mixed and paned (how loud and where in the stereo panorama the signals are put). E.g. if you want Path A on the left side and Path B on both equally you set A Pan to 100% left and B Pan to Center.

The first 21 default presets are FX presets.

Imagine the paths (represented as lines) are stereo cables. Sometimes a stereo signal travels through it, sometimes a dual mono signal. If you use both Paths (A and B) you have two stereo paths. The mixer block defines how two stereo signals are mixed. In your case the signal on path A set central will leave the mixer block on L and R while B set fully right will leave the mixer block on R only. Stereo blocks process the L and R input unmixed and put out a stereo signal. Mono blocks mix L and R input and put out a signal that is the same on L and R (dual mono). "putting the reverb on path B makes it slightly noisy" Can you describe the noise? Which reverb do you use?

The Line 6 HX One has 128 preset locations but over 250 effects models.

Use the 4 cable method (4CM) and add a fifth cable to connect HX FX Out R with the Orange's FX Return R.

On One nice way to use reverbs like the Searchlight is to dial it in more on the suttle side and then add a Heliosphere Delay after it for the ridiculous lush infinity part. Here is a quick demo: dry -> added Searchlight -> added Heliosphere. (forgive the shouty sound of the lead guitar part)

Strymon is a company and not a reverb. I know you know that. This is just to nudge you into being more specific and point to concrete sound examples that you want to replicate.

What you describe as "boxy" and "chorused" is likely the phase canceling between direct and effect signal due to the latency (~2 ms) of the Stomp. The parallel FX loop of the Powerball is the cause for this. Set the Powerball's FX Loop Balance knob all the way to Effect to turn it into a serial FX loop. Alternatively only use time based effects (delay, reverb, chorus, phaser, flanger etc) with Mix set to 100% after the HX's FX Loop block. In other words: make sure there is no direct signal that can cause phase issues in combination with the direct signal of the Engl's FX loop when it's used as a parallel loop.

Well, the Q Filter is an option if you want to tweak. I used this block as my wah (Type: LoPass) until we got the Teardrop Bass Q. If you need a starting point I tried to approximate the UK Wah 846 and came up with these settings: Freq: controller assigned to the expression pedal with Min 45%, Max 85% Q: controller assigned to the expression pedal with Min 75%, Max 35% Gain: 10% Type: Bandpass Mix: 100% Level: +1 dB It's reasonably close but has less bass, so to get closer I'd have to add a bass boosting eq block.

Yes. Select the expression pedal (instead of a footswitch) in Bypass Assign for the Wah block (and other blocks if you like).
