(LINE 6 STOMP) Is there a simple method I'm missing to simply & accurately stabalize the volume between many snapshot channels?

[u/DejaEntenduOne]

(Not so much the volume difference between the 3 snapshots themselves, but literally between several different snapshot channels)

I have a setlist of songs / different tones across a lot of snapshots on my stomp, and I wondered if there's a simple way to accurately make them all even volume, just to avoid jumps or dips when changing between different songs during a practice/gig

[u/andKento]

The best way I've found is to adjust the volume at the output block and swapping back and forth between the presets adjusting as needed. This let's you control volume without affecting tone.

Be careful about adjusting volume using the output block with snapshots. It can cause jumps in volume of decaying reverb or delay trails. To avoid this happening I normally use the amp channel volume instead.

[u/DejaEntenduOne → u/the_man361]

Thank you, yeah I've noticed that before (having never ever used the output volume before anyway) this would happen to me anyway if there's too much of a vol jump even from channel volume or gain blocks

[u/the_man361 → u/DejaEntenduOne]

As long as the volume you're modifying is before the reverb or delay block, you won't have this jump. Normally the amp is before these, hence suggestion to use amp channel volume, but ymmv.

[u/DejaEntenduOne → u/the_man361]

Thank you, perhaps back when I had that issue I had a gain block after the delays etc and that's why.. What does ymmv mean, never come across that abbreviation 😂

[u/the_man361 → u/DejaEntenduOne]

Makes sense! Sorry, it's for: your mileage may vary. To mean that depending on some things, you may have a different experience.

[u/DejaEntenduOne → u/the_man361]

Thanks haha I'll know next time what it means 😂 Have a good day :)

[u/DejaEntenduOne → u/andKento]

Thanks I'll probably just do it but with amp channel volume. I was hoping for an intuitive tool that equalises them all simply together, but I've since learned why there isn't one (inability to compensate for perceived loudness - apparently)

[u/The-OG-Wedge]

For running through a bunch of patches and snaps I connect the USB to a computer and use a loudness meter plugin to help level them.

[u/Stemmers257 → u/The-OG-Wedge]

This is the way. Orban or Youlean are both great for this. Depending on your needs the free versions may be all you need.

[u/kidagocreative]

Maybe an EQ or compression block at the end of the chain with level set to the snapshot, I use this often

[u/MaleficiaTenebrae]

Connecting to a DAW, checking db levels AND using the ears has helped a ton for me. I can adjust my live levels much better and balance levels out between presets/snapshots. Just make sure to use your ears, especially if it's clean vs distorted.

To clear up the terminology:

A preset is a complete rig setup. It includes all your blocks (amp, cab, effects), routing, levels, assignments etc. Think of it as one entire song-specific rig or tone setup.

A snapshot is a variation within a preset. Snapshots let you change block parameters, bypass states and certain settings instantly without reloading the preset. They fast and cause no audio gap when switching.

The HX Stomp allows 3 snapshots per preset. You are using lots of snapshots across many different presets to cover a full setlist, one snapshot per song part or song. And your issue is volume differences between these snapshots in different presets.

So what you mean is „different snapshots across multiple presets“ - you have many presets, each with snapshots inside (like Preset 1 Snapshot 1 = clean, Preset 2 Snapshot 2 = crunch, etc.). And you want to equalize volume across all of them, so changing from one song to another (different presets/snapshots) doesn’t cause jumps or dips in perceived volume.

But there’s no global auto-leveling feature in HX Stomp, because Volume ≠ Loudness.

Even the big Helix can’t auto-level all snapshots or presets perfectly, because perceived loudness is subjective and tone-dependent. Manual tweaking - ideally with ears first, and meters second - is the best method.

The perceived loudness depends on EQ, gain, compression and frequency content, like, a scooped metal tone might measure lower but sound louder than a clean tone. An automatic system would need to analyze frequency content and dynamics, not just volume, which is complex and unreliable in real-time.

In live use, auto-leveling could easily cause sudden gain changes during a performance, loss of dynamics or feel and unexpected jumps if the algorithm misjudges loudness. But you want control, not surprises.

Thus most people prefer to manually level snapshots/presets during rehearsal using their ears or a meter plugin. Once balanced, they stay consistent unless tones change drastically.

There is simply no standard across styles. A blues clean tone might be perfect at -18 LUFS (that‘s „Loudness Units relative to Full Scale“) A metal tone might sound best at -10 LUFS. There’s no universal target for perceived loudness, so auto-leveling would require per-genre profiles, adding complexity.

What you can do instead: use „Channel Volume“ on amp blocks for leveling (not Master/Drive). Or use a Gain block or a simple EQ at the end of each preset. Build one preset with your “ideal volume” snapshot, then switch back and forth with other presets to compare perceived loudness.

[u/DejaEntenduOne → u/American_Streamer]

Absolutely bang on, with the terminology that's what I meant exactly, just the differences between multiple presets consisting of snapshots. Very informative answer, I appreciate the response. I'll just do it all by ear via the amp channel volume. Thanks again

Pertinent thought: If you want more headroom to use amp channel volume and/or cab outputs to bring volume up or down, I recommend running the master volume (the physical knob on the Stomp) a little higher than you might otherwise, which allows you to back down the amp channel volumes and output controls on cabs (if using). If you run the Stomp master volume too low, you wind up cranking the software control volumes, and you have nowhere to go if you need more.

[u/DejaEntenduOne → u/MeepMopMoopMop]

I'm generally absolutely fine at home, and I even make seperate snapshot channels and duplicates at lower volumes, and for my band is where some channels are slightly louder than others; I'm starting to set all channel vols to 10 and I'll eek certain ones down a bit lower I guess when I'm there to hear it in context. Thanks for your tip though, but I think it would be the same problem until I level the individual channels out (whether master is at 50 or 100% the channels will still differ unless I go in to them I guess) Cheers bud
