fix it

The modeler is in Preset mode . Fix: Press FS6, marked MODE.

The LT does not have one . Fix: Mic and aux inputs are Helix Floor features. The LT has a single GUITAR IN.

They share one jack . Fix: EXP PEDAL 2 and EXT AMP are the same socket on an LT. Pick one, or use the built-in pedal and free the jack for amp switching.

One knob drives every output . Fix: The LT has no separate headphone level. Set VOLUME for the desk and monitor from a separate feed.

Using the RIGHT output alone . Fix: Both pairs are stereo. LEFT/MONO is the one that sums to mono.

A cab block into a real guitar cab . Fix: Two speaker simulations are stacked. Bypass the cab, or use an Amp model instead of Amp+Cab.

A ground loop . Fix: Press the GND/LIFT switch on the rear panel beside the XLR outputs.

A hard cap, not the DSP ceiling . Fix: Four amps per preset, two per path. One looper per preset. One poly effect per path.

Out of DSP . Fix: Make a stereo block mono, or swap a Legacy cab for the newer IR-based one.

The preset was never saved . Fix: An “E” beside the preset name means edited and unsaved. Press SAVE twice to keep the edits.

Snapshot Edits is set to Discard . Fix: Global Settings > Preferences > Snapshot Edits sets this. Recall (the default) keeps your changes as you left them. Discard returns the snapshot to its last-saved state. Discard suits playing live and loses edits while you are building. Hold BYPASS and press SAVE to flip it at any time. The camera icon on the Home screen is gray for Recall and red for Discard.

Nothing has been changed in it yet . Fix: An unedited snapshot carries the state you arrived with. It becomes its own sound the moment you change something in it. Nothing is broken.

It recalls whichever snapshot was active when the preset was saved . Fix: Saving a preset stores all of its snapshots and remembers which one you were on. If a song should always start on the intro sound, select that snapshot and then save. The choice is made at save time, not at load time.

Snapshot Mode Switches is set to Auto Return . Fix: Set Global Settings > Footswitches > Snapshot Mode Switches to Manual Return and it stays in snapshot mode until you press CANCEL. Auto Return suits occasional snapshot use. Manual Return suits a set played on snapshots.

That block's Trails setting is Off . Fix: Trails Off mutes repeats and decays the moment the block is bypassed. Trails On lets them ring out, through a bypass and through a snapshot change. It is set per block, so check every delay and reverb.

The delay is synced to tempo, and the new preset has a different one . Fix: A tempo-synced delay re-syncs its trails to the incoming preset's BPM, so the tail still ringing changes speed. To hold the speed across a change, set that delay in milliseconds instead of a note value.

No—Line 6 flag this in capitals, twice . Fix: Never connect these XLR outputs to a device whose XLR inputs have 48V phantom power enabled. On a desk, that means switching phantom off for those channels before you plug in, not after.

Only one digital output can be active at a time . Fix: S/PDIF and AES/EBU are a choice, not a pair. Pick one in Global Settings > Ins/Outs. Connecting an L6 LINK device, such as a Powercab, disables the S/PDIF output automatically.

It is routed somewhere other than where you are listening . Fix: Global Settings > Ins/Outs page 3, Volume Knob Controls, sets which outputs the knob touches. Set to Digital it controls nothing at all and both output pairs sit at unity. That is deliberate, for rigs where front of house sets the level.

This browser has no WebUSB, which one-click install uses to reach the Helix LT . Fix: Open this page on a computer in Chrome or Edge, or download the file and import it with HX Edit.

HX Edit holds the USB connection exclusively while it runs . Fix: Quit HX Edit completely, then connect again. Closing its window does not quit the app.

The modeler is off, or the USB cable is not plugged into the computer . Fix: Connect your Helix LT via USB and power it on.

Nothing was picked in the browser prompt . Fix: Click connect again and pick your Helix LT in the browser prompt.

HX Edit is holding the USB connection . Fix: Quit HX Edit if it is running, then connect again.

HX Edit or the modeler’s own screen was busy with the preset list . Fix: Quit HX Edit, leave the modeler on its home view, then read the list again.

No setlist slot was chosen . Fix: Pick a setlist and slot—the first empty one is pre-selected. A used slot shows what it will overwrite.

The write finished but reading the slot back did not show the new preset . Fix: Check the slot on the modeler. If the old preset is still there, install again.

HX Edit was open and refused the write for the modeler . Fix: Quit HX Edit, then install again.

The connection dropped part-way through . Fix: Reconnect the modeler and install again.

The modeler plugged in is not the model picked in “Your modeler” . Fix: Pick the model the message names in “Your modeler” above, then connect again.

Another preset is still being sent . Fix: Wait for it to finish, then send the next one.

One-click install isn’t available in this browser or on this device . Fix: Download the .hlx preset file. Open HX Edit and connect your Helix via USB. Drag the .hlx onto a slot in the preset list. The modeler saves it.

The connection or the modeler stopped answering mid-install . Fix: Quit HX Edit, reconnect the Helix LT, then try again.
