Oversampling Mode was added in firmware 19.02 and later for the Axe-Fx III. Select between BEST QUALITY and MIN. LATENCY, where BEST QUALITY is equal to previous firmware. Oversampling applies only to Amp and Drive blocks (non-linear). BEST QUALITY is linear-phase oversampling, MIN. LATENCY is minimum-phase oversampling.

<blockquote>"It selects between two different interpolation/decimation kernels. Best Quality yields the least aliasing and best phase response at the expense of latency. This is the kernel used in prior firmwares. Min. Latency trades aliasing and phase response for reduced latency. The Amp and Drive block have about 0.5ms less latency each when using Min. Latency. You can achieve total latency of around 1.5ms or less when using Min. Latency." [https://forum.fractalaudio.com/threads/axe-fx-iii-firmware-release-version-19-02.181728/post-2228373]</blockquote>

==Gapless Changes==
 +
 
 +
* Axe-Fx III, FM9, FM3, VP4
 +
 
 +
In current firmware, preset, scene and channel changes are gapless, if desired. A global parameter allows turning this feature on or off. OFF is the behavior prior to current firmware. The default is ON, which increases CPU usage a little. [https://forum.fractalaudio.com/threads/axe-fx-iii-firmware-23-00-public-beta-4.198988/page-4#post-2476508]
 +
 
 +
To enable gapless preset switching on the FM9 and FM3, you also need to set Spillover to ALL and save all presets under the current firmware.

 +
There are caveats:
 +
#  If presets are using a lot of CPU then the gapless switching may not work as there is not enough CPU available.
 +
# If presets are "stale" (saved under an older revision) then gapless switching may not work until the presets are saved. This is because the preset is being updated during the switchover.
 +
# If you switch presets rapidly you may get a gap because a lot of stuff goes on in the background after switching presets to get ready for the next preset change. If you switch before these background tasks are completed then you'll get a gap. It can take a few seconds for the tasks to complete.

When using the VP4 with a single input, set the Input Mode to 'MONO' and connect to the L/Mono input only. When using the VP4 as a stereo device, make sure to set the Input Mode to "STEREO" and always connect cables to both the left and right inputs (L/Mono and Right).

==Input 1 Left Select==
 
 
 
* Axe-Fx II
 
 
 
Input 1 is split: it appears at the front (mono) as well as on the rear (mono or stereo). This parameter tells the Axe-Fx II if the front input or the rear input is used to connect the instrument, and defaults to front.
 
 
 
The rear port has the same impedance as the front input (1 Mohm, for guitars) but it operates at LINE level instead of instrument level.
 
 
 
The front input does not disable Input 1 left at the rear. Use the menu to select either the front input or rear input. You can leave everything plugged in.
 
 
 
<blockquote>"Input 1 on the rear is a very high impedance input (1 Mohm). It is compatible with low impedance outputs. Most people don't understand the real meaning of impedance and think you need to connect low impedance to low impedance but that's only with passive devices and is a relic of the old days when transformers were used to get the best power transfer. Nowadays we have active inputs with very high impedance which are compatible with a broad range of source impedances."

Firmware 18 for the Axe-Fx III (FM3 and FM9 followed) added the MUTE option. This allows muting the analog outputs while still passing data via USB. This can be used when using the Axe-Fx III in conjunction with computer plug-ins.
+
From the [[Owners_Manuals|Axe-Fx III Owner's Manual]]:
 +
 
 +
* '''Stereo''' – No special settings required.
 +
* '''Half-Stereo''' – Leaving the Axe‐Fx III in its default stereo conguration but connecting only one (Left) output results in a “half‐stereo” setup. This works fine, aside from the exceptions such as ping-pong, panning, etc). No special settings required.
 +
* '''Dual Mono''' – Sonically, this is identical to half-stereo, with the same limitations, except that mono signal is produced at both the left and right jacks so you can connect to two monitors. To switch to dual mono, go to [[Setup menu|I/O > Audio]] and set Mode for the desired output to “COPY L->R”.
 +
* '''Summed Mono''' – Left and right channels are added together resulting in an identical mono signal at both left and right outputs. This has the advantage of not discarding half of the sound, but summing has its own issues. For example, short delays or phase differences between channels can result in strange artifacts or even total cancellation. To switch to summed mono, [[Setup menu|I/O > Audio]] and set Output Mode for the desired output to “SUM L+R”.
 +
 
 +
On the VP4, USB and SPDIF audio go directly to the converters in stereo, so the Output Mode setting does not apply. Also, the setting does not apply when running the VP4 in 4CM mode.
 +
 
 +
The MUTE option in current firmware allows muting the analog outputs while still passing data via USB. This can be used in conjunction with computer plug-ins.
  
 
Incoming computer audio such as YouTube is NOT muted when using the new MUTE OUT1 option in I/O > Audio. When recording or playing back in a DAW, with the DAW track set to USB channels 1-2, incoming audio from the DAW is also NOT muted when using the new MUTE OUT1 option in I/O > Audio, so you'll hear software monitoring only.

'''FX8''' — The POST LEVEL parameter switches the FX8 between +4dB (default) and -10dB. Use +4dB if the unit connects to a line-level port on another device.

The Setup menu on the Axe-Fx III, FM9, FM3 and VP4 gives access to important system parameters. It has the following submenus (depending on the device):

FC Controllers menu

This menu appears on the Axe-Fx III only.

It lets you configure connected FC-6 and FC-12 controllers. Read FC-6 and FC-12 foot controllers for more information.

Alternatively, use the editor.

Expression pedals and external switches that are connected directly to the Axe-Fx III need to be configured in the I/O > Pedal menu, not the FC Controllers menu.

FC Controllers/Onboard Switches menu

This menu appears on the FM3 and FM9 only. It lets you configure the onboard switches as well as connected FC-6 and FC-12 controllers (see above). Read FC-6 and FC-12 foot controllers for more information.

Alternatively, use the editor.

Expression pedals and external switches that are connected directly to the FM9 or FM3 need to be configured in the I/O > Pedal menu, not the FC Controllers menu.

Footswitches menu

This menu appears on the VP4 only and lets you configure the 4 onboard switches.

Some parameters are directly available within the Setup menu:

  • Switch LED Brightness
  • Fade Selected Effect Timeout

Read the Owners manual.

Pedals menu

This menu appears on the VP4 only and lets you configure connected expression pedals and external switches.

Read the Owners manual.

FC Setlists/Songs menu

This menu appears on the Axe-Fx III, FM3 and FM9. Alternatively, use the editor.

Read Songs and setlists for more information.

Gapless Changes

  • Axe-Fx III, FM9, FM3, VP4

In current firmware, preset, scene and channel changes are gapless, if desired. A global parameter allows turning this feature on or off. OFF is the behavior prior to current firmware. The default is ON, which increases CPU usage a little. [1]

To enable gapless preset switching on the FM9 and FM3, you also need to set Spillover to ALL and save all presets under the current firmware.

FRACTAL AUDIO QUOTES


[2] There are caveats:

  1. If presets are using a lot of CPU then the gapless switching may not work as there is not enough CPU available.
  2. If presets are "stale" (saved under an older revision) then gapless switching may not work until the presets are saved. This is because the preset is being updated during the switchover.
  3. If you switch presets rapidly you may get a gap because a lot of stuff goes on in the background after switching presets to get ready for the next preset change. If you switch before these background tasks are completed then you'll get a gap. It can take a few seconds for the tasks to complete.

Input 1 Gain

  • FM3

This allows trimming Input 1's gain to adjust for variations in guitar output level, without having to adjust each preset.

On the Axe-Fx III and FM9, this parameter is located in the I/O menu.

Startup Mode

Available on the VP4 only. It lets you specify the mode that will be active when the VP4 is powered on: Gig, Presets, Scenes or Effects.

Automatic VP4 Bypass

  • VP4

The VP4's features a buffered analog bypass mode, which passes the signal directly from input to output without digital conversion, latency, or processing. To have analog bypass activate automatically when all four effects are bypassed, set this option to ON. This mode can also be engaged through a switch.

FRACTAL AUDIO QUOTES


[3] We considered analog dry-through early in the design phase but it just causes more problems than it's worth. If it were a dedicated delay or reverb device then it would make sense but once you add drives and wahs and EQs it makes things too confusing for the average user.

LCD contrast

VP4 only.

Switch LED Brightness

VP4 only.

Fade Selected Effect Timeout

VP4 only.

Reset System Parameters

The VP4 doesn't have a Utilities menu, so Reset_system_parameters is accessible directly within the Setup menu.

Clear All Presets

The VP4 doesn't have a Utilities menu, so this parameter is accessible directly within the Setup menu.

System Info

The VP4 doesn't have a Utilities menu, so this parameter is accessible directly within the Setup menu.

I/O menu

This menu lets you configure all audio inputs and outputs, return levels of digital audio, and the pedal port(s) at the rear of the hardware. These settings can be adjusted on the hardware and in the current generation editors. On the VP4, this menu is named: Audio.

A backup of the system settings, created with Fractal-Bot, contains all I/O menu settings.

A/D Sensitivity

  • Axe-Fx II, Axe-Fx III, FM9

Previously named: A/D Input Levels.

Input 1 Gain

  • Axe-Fx III, FM9

This allows trimming Input 1's gain to adjust for variations in guitar output level, without having to adjust each preset.

On the FM3, this parameter is located in the Global menu.

Word Clock

  • Axe-Fx II, Axe-Fx III, FM9

Digital Input Source

  • Axe-Fx III
  • FM9

The Axe-Fx III defaults to AES.

SPDIF/AES Out Source

  • Axe-Fx II
  • Axe-Fx III: select an input or output as the source for AES/SPDIF output. Default: Output 2.
  • FM9 and FM3: select an input or output as the source for SPDIF output (AES not supported)

USB Output 3,4 Record Source

  • FM3

Select the source for computer inputs 3 and 4.

USB Output 7.8 Source

  • Axe-Fx III, FM9

Selects the source for USB outputs 7 and 8. The default is Input 2.

USB Playback Destination

  • FM3

Select Output 1 (default) or Output 2 as the destination for computer outputs 1 and 2. This allows for the easy separation of processed guitar to Out 1 and default computer system audio to Output 2. If you use only Output 2, you can now hear both processed guitar and USB audio by using the settings Output 2 Copy: OUTPUT 1 and USB 1/2 Playback Destination: OUTPUT 2.

Select Input 1, Output 1 or Output 2 as the destination for computer outputs 3 and 4.

USB Output Mapping

  • Axe-Fx III, FM9

This allows routing USB channels 1,2 to Output 1 or Output 2 and channels 3,4 to Output 2 or Output 1. This provides a way to route the computer's system audio, entering the processor, to Output 2 instead of Output 1.

Default: 1/2 -> OUT1, 3/4 -> OUT2.

USB Buffer Size

  • Axe-Fx II, FM3

Input 1 Source (Main Input Source)

  • Axe-Fx II
  • Axe-Fx III, FM9: select the source of Input 1: ANALOG (default, instrument input), or DIGITAL (as selected in Digital Input Source)
  • FM3: select the source of Input: ANALOG or USB channels 3+4

The USB setting is meant for reamping a DI signal through USB.

DigitalIO.png

Input Source

  • Axe-Fx III, FM9, VP4

Select the source of the input: ANALOG (default), or DIGITAL as selected in Digital Input Source.

On the VP4, choose between: ANALOG, DIGITAL, USB Channels 3/4 (computer).

See the picture above.

Input Pad

  • FX8, AX8, FM3, VP4

Input Mode

  • Axe-Fx II, Axe-Fx III, AX8, FX8, FM9, FM3, VP4

Values: Stereo, Left Only, Right Only, Sum L+R, Mono (VP4 only).

When connecting a guitar to the front instrument input on the Axe-Fx II, set this parameter to LEFT ONLY (default). You'd only use SUM L+R or STEREO when connecting a stereo instrument to Input 1 (rear). Input 1 front on the Axe-Fx III is always mono.

IMPORTANT: Do not select SUM L+R or STEREO when using only the Left input. This may introduce noise from the disconnected Right input and attenuates the signal level by 6 dB.

Input 2 Mode controls the same thing for Input 2 on the FM3, Axe-Fx II, AX8, and FX8. And Input 3 Mode and Input 4 Mode control the same thing for inputs 3 and 4 on the Axe-Fx III.

There's no Mode parameter for Input 1 on the Axe-Fx III.

When using the VP4 with a single input, set the Input Mode to 'MONO' and connect to the L/Mono input only. When using the VP4 as a stereo device, make sure to set the Input Mode to "STEREO" and always connect cables to both the left and right inputs (L/Mono and Right). The Input Mode setting is overridden when the global "4CM Routing" option is ENABLED.

Output Mode

  • Axe-Fx II
  • Axe-Fx III
  • FM9
  • FM3
  • AX8
  • FX8
  • VP4

This determines if the output signal is stereo, or one of the two mono modes: Sum L+R or Copy L>R.

From the Axe-Fx III Owner's Manual:

  • Stereo – No special settings required.
  • Half-Stereo – Leaving the Axe‐Fx III in its default stereo conguration but connecting only one (Left) output results in a “half‐stereo” setup. This works fine, aside from the exceptions such as ping-pong, panning, etc). No special settings required.
  • Dual Mono – Sonically, this is identical to half-stereo, with the same limitations, except that mono signal is produced at both the left and right jacks so you can connect to two monitors. To switch to dual mono, go to I/O > Audio and set Mode for the desired output to “COPY L->R”.
  • Summed Mono – Left and right channels are added together resulting in an identical mono signal at both left and right outputs. This has the advantage of not discarding half of the sound, but summing has its own issues. For example, short delays or phase differences between channels can result in strange artifacts or even total cancellation. To switch to summed mono, I/O > Audio and set Output Mode for the desired output to “SUM L+R”.

On the VP4, USB and SPDIF audio go directly to the converters in stereo, so the Output Mode setting does not apply. Also, the setting does not apply when running the VP4 in 4CM mode.

The MUTE option in current firmware allows muting the analog outputs while still passing data via USB. This can be used in conjunction with computer plug-ins.

Incoming computer audio such as YouTube is NOT muted when using the new MUTE OUT1 option in I/O > Audio. When recording or playing back in a DAW, with the DAW track set to USB channels 1-2, incoming audio from the DAW is also NOT muted when using the new MUTE OUT1 option in I/O > Audio, so you'll hear software monitoring only.

For more information read:

Output Level (Nominal Out Level, Post Level)

  • Axe-Fx III
  • FM9
  • FM3
  • AX8
  • FX8

Set to -10dB when connecting the input to a pedal, a guitar amplifier input, or when the output is clipping the input section of another device. Use +4dB when connecting to the output of a pro-level device or to a louder output signal.

Note: the III and FM3 default to a -10 dB nominal output level, so their output level is lower than that of the II and the AX8.

FRACTAL AUDIO QUOTES


Axe-Fx III:

[4] The default Output Level for Output 1 and 2 is -10 dBv. This was done to reduce the number of support cases due to people overloading the inputs on consumer-grade interfaces, mixers, etc. (IOW cheap stuff). Most professional gear runs at +4 dBu so if using a pro-grade interface, mixer, etc. you may want to go into the Global menu and change the level to +4 dBu.

FX8:

The POST LEVEL parameter switches the FX8 between +4dB (default) and -10dB. Use +4dB if the unit connects to a line-level port on another device. Use -10dB if the unit connects to a guitar amplifier's instrument input or a pedal. If you're using the FX8 in a Four Cable Method (4CM) setup, and you're experiencing hiss, try switching to another Post Level value.

Output Boost/Pad

  • Axe-Fx II
  • AX8
  • Axe-Fx III: output 3 and 4
  • FM9: output 3
  • FM3: output 2

The Boost/Pad parameter optimizes the signal level to reduce noise in certain scenarios, such as a 4CM setup (Four Cable Method), when placing the device in front of a traditional amp, or when integrating an external pedal.

The Output Boost/Pad is supported for unity gain outputs.

When putting the Axe-Fx II or III in front of a real amp using Output 3 or 4 (FM9: output 3, FM3: output 2), maximize Boost/Pad to make sure the full range of the D/A converter is used.

When using a 4CM setup: increase Boost/Pad and prevent clipping. Turn OUT on the front panel fully open for unity gain. Use Input Level IN to finetune the signal level.

Boost/Pad is not intended for boosting USB output (although it does have that effect).

FRACTAL AUDIO QUOTES


[5] Boost/pad only applies to the outputs, that's why it's under the Output header.

PREVIOUS GENERATIONS


[6] Usually you will use this when you send the effect loop out before the amp block. The signal will be weak going to the D/A converters. This allows you to boost the signal to the D/A converters w/ maintaining the same output level.

Output Phase

  • Axe-Fx II
  • Axe-Fx III
  • FM9
  • FM3
  • AX8
  • VP4

This lets you invert the phase of the signal, if necessary.

Copy Output 1 / Output 2 Echo / Copy

  • Axe-Fx II
  • Axe-Fx III
  • FM9
  • FM3
  • AX8

This determines the signal that is sent from Output 2.

Axe-Fx III:

  • ON: a copy of the Output 1 signal (excluding incoming USB audio) is sent to Output 2.
  • OFF: the Output 2 block controls the output.

FM3:

  • Input 1: sends an exact copy of the direct input signal (unprocessed DI signal) through Output 2.
  • Output 1: a copy of the Output 1 signal (excluding incoming USB audio) is sent to Output 2.
  • None.

If the Axe-Fx III or FM3 preset contains an Output 2 block, this parameter is ignored.

Axe-Fx II:

  • None.
  • Output 1: Output 2 sends an exact copy of the Output 1 signal (excluding incoming USB audio), UNLESS the preset contains an FX Loop block.
  • Input 1: Output 2 sends an exact copy of the direct input signal (unprocessed). This sends a DI signal through Output 2, UNLESS the preset contains an FX Loop block.

Copy Input 1

  • Axe-Fx III
  • FM9

This determines whether a copy of Output 1 is sent through Output 3 or 4, for example for reamping. It's the same as connecting the Input 1 block to the Output 3/4 block.

If the preset contains an Output 3 block or Output 4 block, this parameter is ignored.

Output Type

  • FM3

This lets you choose between line level or unity gain output for Output 2.

UNITY GAIN​
To use FM3 Out 2 in unity gain applications, such as when connecting to a tube amp or certain pedals, confirm the following settings in the "Output 2 Configuration" section under SETUP: I/O: Audio​:

  • Output Type: Unity Gain​
  • Boost/Pad: This optional setting may be increased to lower the noise floor. This can be useful, for example, when connecting to a "gainy" tube amp. Be careful however, as higher settings can cause clipping in the FM3. Watch the Status LEDs and reduce preset levels or turn this setting down if needed.​
  • Output 2 Copy: Typically, "None", but there are also applications for copying "IN 1" to OUT 2, such as when recording an analog DI at unity gain via Out 2 while also recording the processed signal via Out 1. Remember though that placing an OUT2 block on the grid will override any Output 2 Copy setting, passing instead whatever audio is sent to the block. Other settings such as Level, Boost/Pad, etc. are not affected by the presence of the OUT2 grid block.​
  • Set Out 2 Mode and Phase as desired.

For Unity Gain applications, set the Out 2 top panel knob fully clockwise to the highest setting.​

LINE LEVEL​
To use FM3 Out 2 for Line Level applications — such as when connecting to FRFR guitar speakers, studio monitors, mixers, etc., confirm the following settings in the "Output 2 Configuration" section under SETUP: I/O: Audio​

  • Output Type: Line Level​
  • Output Level: -10dBV or +4dBu (most pro devices operate at +4)​
  • Output 2 Copy: As desired: "None”, or "Out 1" if you want Out 2 to reproduce the signal at Out 1 without needing an OUT2 grid block. You could use this, for example, when connecting to personal monitors via Out 2 while Out 1 is connected to a house PA. Remember though that placing an OUT 2 block on the grid will override the COPY OUT 2 setting, passing instead whatever audio is sent to the grid block. Other settings such as Output 2 Level (+4/-10) are not affected by the presence of the Out 2 block.​
  • Set Out 2 Mode and Phase as desired.

For Line Level applications, set the Out 2 top panel knob as desired, starting fully counterclockwise and then increasing gradually until the desired output level is achieved.​

Tips, tricks and troubleshooting

Backup and restore system settings

A backup of the system settings, created with Fractal-Bot, contains all settings in the Setup menu and submenus.

When I/O menu parameters won’t stick

If adjusted parameters in the I/O menu are restored to their default values after powering off and on, there’s probably an issue with the internal battery (if the device has one) such as it is exhausted or is loose.

FRACTAL AUDIO QUOTES


Axe-Fx III:

[7] The Axe-Fx III uses a battery for system data backup. Whenever the user changes any global data that data is flushed to battery-backed storage. We use battery-backed SRAM instead of EEPROM or FLASH because it's very fast and unlimited endurance. EEPROM is very slow and there's a risk that the user turns the power off before the flush is finished. FLASH has limited endurance (as well as being slower the SRAM) and there's a risk of wear-out. The battery should last 10 years under normal conditions and is user replaceable.

FM3:

[8] The FM-3 doesn't have a battery. It uses EEPROM for system data.

If your AX8 seems to lose its system setting, read Reset system parameters for more information.

VP4 Setup menu

On the VP4:

  • Audio menu = I/O menu
