fix it

INPUT 1 LEFT SELECT is set to REAR . Fix: Change it to FRONT in the I/O menu. It is a setting, not a physical switch.

This generation uses X/Y . Fix: Every block has two variants, X and Y, not four channels. Channels arrived with the current generation.

The firmware line ended at Ares . Fix: Cygnus is current-generation only. There is no upgrade path, and presets do not cross between generations.

The port differs by model . Fix: XL, XL+ and Mark II use EtherCON with FASLINK. The original Axe-Fx II has a plain Ethernet port. Check which you have before buying cables.

A ground loop . Fix: Use a Humbuster cable from the quarter-inch output—TRS at the Axe-Fx, TS at the amp.

Presets where scenes would do . Fix: Eight scenes per preset, and turning Quick Control knob A on the recall screen changes them without a foot controller.

Model differences . Fix: The XL and XL+ hold 768 presets and 1024 cabs. The original and Mark II hold 384 and 100.

A cable, before anything else . Fix: Most of the time it is a faulty or disconnected cable. Plug headphones straight into the modeler. If the preset sounds fine there, the fault is downstream and nothing on it needs changing.

The path does not reach the output . Fix: A grid can look connected and not be. Check the preset begins with an Input block and ends with an Output block, and that those match the jacks you have cabled. Then change each block to a shunt in turn, leaving the Amp and Cab until last, and listen for where the sound returns.

A modifier is holding a level at zero . Fix: If something is assigned to a volume or level control and the pedal or switch it expects is not plugged in, the level sits wherever that missing controller says, usually at silence. Either remove the modifier, or set the external controller's initial value to 100% instead of 0%.

The preset wants a User Cab you do not have . Fix: Presets you downloaded often reference a cab IR that lives on the author's modeler and not yours. Point the Cab block at a factory cab and the sound comes back.

Something in the current state has wedged . Fix: Reboot the modeler first. If that does not work, disconnect MIDI, USB and the foot controller, then hold RECALL while powering on. It comes up on an empty preset, which does not touch anything you have saved.

The global power amp or cab simulation got switched off . Fix: Check the CONFIG page of the Global menu. These are global switches, so the change hits every preset at once.

One preset only—SAG is fully down . Fix: If it is a single preset, not all of them, check that the Amp block's SAG has not been turned fully counter-clockwise. Then check the Global Graphic EQ.

A stereo sound is being summed to mono . Fix: That specific hollow, flanged quality is the sound of stereo collapsing. Check OUTPUT 1 MODE and OUTPUT 2 MODE on the AUDIO page of the I/O menu against how you are listening. Headphones confirm it in seconds.

The D/A converters are being overdriven . Fix: Those two LEDs light when the converters clip. Bring down your preset levels, or reduce the global BOOST/PAD for whichever output is complaining. At a gig, the GAIN on the Global Graphic EQ does it in one move.

The last edit pushed the preset over . Fix: Undo it by turning the value wheel back the other way. Otherwise navigate around the message and remove a block, or load a different preset. Setting the CAB block to MONO LO-RES frees a useful amount and often solves it.

A modifier owns its bypass . Fix: Once anything is attached to a block's BYPASS MODE modifier slot, that modifier has total control and the switch stops mattering. Either use the modifier to change the state, or remove it.

The main input is set to USB . Fix: Change MAIN INPUT SELECT from USB to ANALOG (IN 1) and you can play along with the computer instead of processing it.

Something around the preset changed, not the preset . Fix: A preset is a list of settings, and those settings are interpreted by whatever firmware is running. The usual culprits are a firmware version change, a different guitar, a different amp at the other end, or external controllers sitting at different values than they were. Global Blocks that have since been edited will also change every preset that references them.

Presets do not move freely across the line . Fix: Axe-Fx II presets do not load on an Axe-Fx III, an FM9 or an FM3, and theirs do not load here. The models largely carry over, so transferring settings by hand generally lands where you expect. The Axe-Fx II's factory cabs live in the Legacy bank on the newer modelers.

MIDI access was refused for gridleak.app, or the prompt was dismissed . Fix: In Chrome open Settings → Privacy and security → Site settings → MIDI devices, and allow gridleak.app. Reload the page, then connect again.

Fractal-Bot or another app is holding the modeler’s MIDI port . Fix: Quit Fractal-Bot and any DAW or MIDI utility, then connect again.

The browser has no Web MIDI . Fix: Use Chrome or Edge on a desktop computer.

This browser has no Web MIDI, which one-click install uses to reach the Axe-Fx II . Fix: Open this page on a computer in Chrome or Edge, or download the file and import it with Fractal-Bot.

Fractal-Bot holds the USB connection exclusively while it runs . Fix: Quit Fractal-Bot 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 Axe-Fx II via USB and power it on.

Nothing was picked in the browser prompt . Fix: Click connect again and pick your Axe-Fx II in the browser prompt.

Fractal-Bot is holding the USB connection . Fix: Quit Fractal-Bot if it is running, then connect again.

The preset was sent, but the modeler did not answer the save . Fix: Check the preset on the Axe-Fx II. If it isn’t there, install again with Fractal-Bot quit.

Fractal-Bot was open and refused the write for the modeler . Fix: Quit Fractal-Bot, then install again.

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

The preset number is outside the modeler’s range . Fix: Enter the preset number as shown in Axe-Edit, then click Check—you’ll see what’s stored there.

The file is damaged or is not a preset for this modeler . Fix: Download the preset for the Axe-Fx II again, then install it.

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 .syx preset file. Open Fractal-Bot and connect your Axe-Fx II via USB. Click "Import" → select the downloaded .syx file. Choose the destination preset slot and click Send.

The connection or the modeler stopped answering mid-install . Fix: Quit Fractal-Bot, reconnect the Axe-Fx II, then try again.
