The EV-1 is an all new EXPRESSION PEDAL, perfect for use with all Fractal Audio Systems products (and many 3rd-party devices). Unlike most expression pedals it has a true linear response with planetary gearing and a long, smooth pedal throw. The EV-1 doubles as an analog volume pedal, with separate IN and OUT jacks connected to an audio-taper pot. It features a sturdy cast metal housing, comfortable non-slip rubber tread, and is available in Black.

<blockquote>"TRS” stands for TIP-RING-SLEEVE and describes the configuration of a 1/4" end plug or jack with three connectors. Normal guitar cables are “TS” (Tip-Sleeve) since they lack the ring required for a third contact. Expression pedals require TRS cables because full control voltage is transmitted to them on one contact (the tip), while less than full voltage is returned to on another (the ring) so the host device is able to sense and utilize the pedal position. The third contact (sleeve) is connected to ground."</blockquote>

==What happens if the pedal is not connected==
+
<blockquote>
 +
[http://forum.fractalaudio.com/posts/1217151]
 +
We make tour-grade equipment. The potentiometer in the EV-1 has a conductive plastic element with IP67 ingress protection. It is rated for 1,000,000 rotations and probably costs 10 times what the pot in other products cost. The housing is cast aluminum which is then powder coated for extra protection. You're getting something you can give to your grandchildren.
 +
</blockquote>
  
−
If the expression pedal is not connected, the processor needs to know what value to use. Disconnecting a pedal that operates as a Volume pedal should not mute the device, for example. The desired “initial” value can be set in the [[MIDI]] menu, through the [[MIDI#Initial_Value_External_Control|External Controller Initial Value parameter]].
+
<blockquote>
 +
The EV-1s are fully made in China except for the pots which are made in USA as nothing in China or Japan met our lifespan requirement (1 million rotations minimum).
  
−
This applies only to pedals that have been assigned using an "external controller" inbetween, not to pedals that are directly connected to the device.

(May 2021) The EV-1 expression pedal will be manufactured in black only going forward.

'''Method 1''' (i.e. control either Wah or Whammy):
+
=Expression pedal=
−
# Insert a Wah block.
 
−
# Insert a Pitch block, directly above or below the Wah in a parallel row. Connect it back to to the main row.
 
−
# In the Modifier menu of BOTH effects (Wah: Frequency; Pitch: Control): set Source to External 1. Enable Auto-engage.
 
−
# Add a Mixer block to the main row, just after Wah and Pitch.
 
−
# Edit Mixer: enter the Modifier menu of the Gain parameter for the row that connects to the Wah. Set Source to another external controller (which will be attached to an IA-switch to switch between Wah and Whammy). Set Start Value to 100% and End Value to 0.
 
−
# Do the same for the row that connects to the Pitch block. But: set Start Value to 0% and End Value to 100%.
 
−
# Program an IA switch to switch between Wah and Whammy, using the Mixer rows. Use the CC of the external controller that you specified while editing the Mixer block, and send "127" for the Wah, and "0" for the Whammy.
 
−
# That's all. Moving the pedal should activate both the Wah and the Pitch block. But thanks to the Mixer block you'll only hear one of these effects. If you're hearing the Wah and the Whammy effects simultaneously, you need to press the IA-switch to get the Mixer block to work
 
  
−
'''Method 2''' (i.e. control Volume and Wah): (source: Bakerman)
+
==Connect a pedal==
−
# Place a Volume block on the grid.
 
−
# Assign an IA switch to an external controller's CC.
 
−
# Assign another external controller the Wah and Volume control knobs.
 
−
# Set the first external controller as a Bypass modifier for both blocks and reverse the slope of one (start 100, end 0).
 
−
# Now the IA switch will toggle between Wah/Volume and the pedal will control both.
 
  
−
'''Method 3''' (use scenes to switch the pedal to another effect, i.e. Wah, Whammy and Volume):
+
The requirements for an expression pedal are:
−
# Put Wah and Pitch and Volume in one column (parallel).
+
* linear resistance taper
−
# Assign an external controller (pedal) to the effects. Set to Auto-Engage in Wah and Pitch.
+
* max resistance of 10-100 kOhm
−
# In Wah and Pitch turn down Level in the block's Y state.
+
* TRS-to-TRS cable connection (<q>stereo jack</q>)
−
# Scene 1 is for Wah. Set Wah to X, set Pitch to Y, bypass Volume.
 
−
# Scene 1 is for Whammy. Set Wah to Y, set Pitch to Y, bypass Volume.
 
−
# Scene 3 is for Volume. Set Wah to Y, set Pitch to Y, engage Volume.
 
−
# To make this work with effcts without X/Y support, use a [http://forum.fractalaudio.com/axe-fx-ii-wish-list/77285-ring-mod-x-y.html#post954149 Scene Controller].

==Tap Tempo or Tuner==
+
==Configure a pedal==
  
−
An external switch can be used for tapping the [[Tempo]] or to activate the [[Tuner]].
+
Pedals which are connected directly to the Fractal Audio device can be configured and calibrated on the Pedal page of the [[Setup menu]]. On the VP4, this is the Setup > Pedals menu.
  
−
==Effect block state: ignore scene and preset switching==
+
Pedals which are connected through another connected device, such as [[FC-6 and FC-12 foot controllers]] or MIDI controllers, must be configured in the configuration menu of that device, including calibration. For the FC controllers, use the FC controllers menu in the [[Setup menu]].
  
−
You can use an external switch to maintain its bypass state when switching presets and scenes.  
+
Always calibrate the pedal before use. This makes sure that the pedal's full sweep range is being used.
  
−
# Connect the switch to a pedal port
+
You can assign the pedal directly to parameters in the preset. Or you can assign an [[External controller]] to that parameter, and then assign the pedal to that specific external controller. The latter option provides more flexibility.
−
# Assign that pedal to an External Controller
 
−
# Assign the Bypass Mode parameter of the effect to that External Controller (modifier menu: Source). Repeat this in each preset which you want to control
 
−
# Now the switch will control the effect's engaged/bypass state, regardless of the effect's stored state, and stay in sync

==What happens if the pedal is not connected==
  
−
==Control multiple effects simultaneously==
+
If a parameter is controlled by a switch or pedal, and that pedal or switch is not connected at startup, the processor needs to know what value to use. Disconnecting a pedal that operates as a Volume pedal should not mute the device, for example.
  
−
It's possible to use your expression pedal for multiple purposes while staying in the same preset. Suppose you have one expression pedal and you want it to use as a wah as well as a Whammy, without switching presets:
+
For parameters that have been assigned to an [[Controllers and modifiers|External controller]], the desired initial value can be set in the [[Setup menu]] under Initial Value.
−
# Insert a Wah block.
 
−
# Insert a Pitch block, directly above or below the Wah in a parallel row. Connect it back to to the main row.
 
−
# In the Modifier menu of BOTH effects (Wah: Frequency parameter; Pitch: Control parameter): set Source to the External controller that's attached to your expression pedal. Set auto-engage to Fast, Medium or Slow.
 
−
# Add a Mixer block to the main row, just after Wah and Pitch.
 
−
# Editing the Mixer: enter the Modifier menu of the Gain parameter for the row that connects to the Wah. Set Source to the external controller that is or will be attached to an IA-switch (which switches between Wah and Whammy). Set Start Value to 100% and End Value to 0.
 
−
# Do the same for the row that connects to the Pitch block. But: set Start Value to 0% and End Value to 100%.
 
−
# Program an IA-switch on your MIDI controller to switch between Wah and Whammy, using the Mixer rows. Use the CC of the external controller that you specified while editing the Mixer block, and send "127" for the Wah, and "0" for the Whammy.
 
−
# This is it. Moving the pedal should activate both the Wah and the Pitch block. But thanks to the Mixer block you'll only hear one of these effects. To bypass the effect hold the pedal in toe-down position. If you're hearing the Wah and the Whammy effects simultaneously, you need to press the IA-switch to get the Mixer block to work.
 
  
−
You don't have to use a Mixer block (available on the Axe-Fx only). [http://forum.fractalaudio.com/axe-fx-ii-discussion/47983-wah-block-mix-parameter.html#post625421 Here's how], or [http://forum.fractalaudio.com/other-midi-controllers/26364-wha-volume-switcher.html read this for another solution]:
+
Current firmware also features activity sensing for internal pedals, FC pedals and external controllers. This stops Auto-Engage from activating an effect if the pedal/controller is not connected. This prevents, for example, a Wah being engaged if Auto-Engage is on but no pedal is connected (i.e., you left your expression pedal at home).
−
# Do the same as above but leave out the Mixer block.
 
−
# Set Bypass mode of one block to Thru and the other block to Mute.
 
−
# Assign an External controller (attached to a switch) to the Balance parameter in each block. Set Start Value to 100% and End Value to 0 in one block, andvice versa in the other.
 
−
# Set Input Select in Drive and Amp blocks after Wah and Pitch to Left or Right, instead of Sum L+R.

The expression pedal inputs on the Axe-Fx and on the FC6/12 have pullup resistors. If a pedal is unplugged the value goes to 100%. This is done so that if a pedal is connected to volume and you forget your volume pedal you'll still have sound.

You can use an external switch to switch presets. This works fine if you have just a few presets to switch between. If the processor has more than one PEDAL jack, you can assign one to increment presets and the other to decrement presets. You can also use a switch to switch scenes, see [[Scenes]].

Since this template was last updated by David Sorlien, two new AxeFx devices have been created.    The XL and XL+ have more or less the same SysEx protocols as the AxeFx ( subject to change ), but have New SysEx device ID codes.  The following is a break down of work required to make AxeForLemur support other Fractal Audio Devices.
+
Configure the switch(es) in the [[Setup menu]].
  
−
Essentially the T1/cTargets/swSettings is a 4 x 4 Switch matrix. Pressing a button will provide a 0..16 button index within the T1/cTargets/swSettings/x variable.  Pressing one of the T1/cTargets/padUpDn will cause the selected T1/cTargets/swSettings/x indexed value to be Incremented/decremented.  The padUpDn/tap() changesbutton matrix.
+
; Switch Behavior : determines how an external switch operates. With the default setting of "Follow Hardware" a switch  behaves as you might expect. If you want a momentary switch to behave like a latching/toggle switch instead, use the "Virtual Toggle" option. Now, every time you tap the switch, its state on the Axe-Fx or FM3 will flip from ON to OFF, or OFF to ON. Note that if you accidentally apply the Virtual Toggle setting to a physical latching switch, you'll need to tap the switch twice for it to toggle.
  
−
Add two more values to devtypes
+
; Switch Polarity : allows reversing the polarity of any connected switch. The option <q>Normal</q> assumes a <q>momentary make</q> switch. Use the option <q>Reverse</q> when using a <q>momentary break</q> switch, or for creative applications.
  
−
  change:
+
An external switch can operate globally as a copy of an onboard switch in any layout by assigning it as a '''Stand In switch'''. It's an exact surrogate for the onboard switch, and can even be used with per-preset functions. Momentary switches are preferred for use as stand-ins, because they more closely mimic the behavior of the on-board switches.

−
Add two more strings to button objet lablels
+
You can assign the switch directly to parameters in the preset. Or you can assign an [[External controller]] to that parameter, and then assign the switch to that specific external controller. The latter option provides more flexibility.

Change Device ID's within SysEx messages to include devie ids { 6 and 7 }
+
A single button switch, connected to the pedal port, can be used to scroll through the first bank of presets. This works fine if you have just a few presets to switch between. And if the processor has more than one PEDAL jack, you can assign one to increment and the other to decrement.

It makes sense to define a class variable like cV.DevID, and make sure it is set on startup by the AxeFx device ID selected by the A,B,C,D device selector.

You can use an external switch to maintain the bypass state of an effect when switching through presets and scenes.  
  
−
===Design Modifiers===
+
# Connect the switch.
 +
# Assign the Bypass Mode parameter of the effect to the switch through an [[External controller]].
 +
# Repeat this in each preset which you want to control.

# Now the switch will control the effect's engaged/bypass state, regardless of the effect's saved state per preset or scene, and stay in sync.

Modifiers provide a means to dynamically change a subset of the block parameters with automatic, and external functions.    The AxeToLemur Script has a partial implementation of Modifiers.  The AxeToLemur.pdf describes 'double tapping' the intended modify-able' control to enable modifier, but this doesn't appear to be within the implementation.
+
=Tips, tricks and troubleshooting=
  
−
Within the 'control's bps[] array, for hw==0, element at index==6 is the Modifier number, if this value is >= 0, then the control should have modify-able values.  This applies to 'bps' of sliders, custom buttons, muxed-sliders.  If the 'control's bps[8] is set to 1, then there is an active modifier on the control.
+
==Pedal ports: ADC levels==
  
−
It is assumed that 'double tapping' the 'Zoom' button will enable a RED "MOD" feature on the Zoom button.  cS.DoubleTap() captures double tap event. This sets cV.dbltapzoom[2] = 1;  A parameter that is 'Modify-able' has a Green 'txt' value.
+
Check the ADC (Analog-to-Digital Converter) levels of the pedal ports in the [[Setup menu]].

Remote control of Fractal Audio devices

Fractal Audio's processors can be remotely controlled in various ways. This includes the use of expression pedals such as Fractal Audio's EV-1 and EV-2 pedals, (see below) and/or external switches, either connected directly to a pedal port on the device, to a MIDI controller or to Fractal Audio's FC-6 and FC-12 foot controllers.

The number of ports, as well as support for a single switch or dual switch, varies per product.

Read the following pages for more information:

Fractal Audio expression pedals

EV-1 expression pedal

The EV-1 is the large version of Fractal Audio’s expression pedal/analog volume pedal.

Product information:

The EV-1 is an all new EXPRESSION PEDAL, perfect for use with all Fractal Audio Systems products (and many 3rd-party devices). Unlike most expression pedals it has a true linear response with planetary gearing and a long, smooth pedal throw. The EV-1 doubles as an analog volume pedal, with separate IN and OUT jacks connected to an audio-taper pot. It features a sturdy cast metal housing, comfortable non-slip rubber tread, and is available in Black.

Specifications:

  • Planetary Gear Drive
  • High-quality dual potentiometer rated for 1M rotations
  • Durable cast aluminum chassis
  • Adjustable pedal tensioner
  • 3 jacks at the front: In, Out and Expression. In and Out are for volume
  • Requires TRS-to-TRS cable when used as an expression pedal
  • Not spring-loaded
  • Built-in analog volume pedal (500K high-impedance)

Read the Product Guide for more information.

FRACTAL AUDIO QUOTES

The planetary gear drive solves the dead zone problem.

[1] They also work as a traditional volume pedal. There are two ganged pots inside, one is a high-impedance log-taper volume pot and the other is a low-impedance linear-taper expression pot. The design is our own.

[2] We make tour-grade equipment. The potentiometer in the EV-1 has a conductive plastic element with IP67 ingress protection. It is rated for 1,000,000 rotations and probably costs 10 times what the pot in other products cost. The housing is cast aluminum which is then powder coated for extra protection. You're getting something you can give to your grandchildren.

The EV-1s are fully made in China except for the pots which are made in USA as nothing in China or Japan met our lifespan requirement (1 million rotations minimum).

(May 2021) The EV-1 expression pedal will be manufactured in black only going forward.

EV-2 expression pedal

The EV-2 is the smaller version of Fractal Audio’s expression pedal/analog volume pedal.

Specifications:

  • Planetary Gear Drive
  • High-quality dual potentiometer rated for 1M rotations
  • Durable cast aluminum chassis
  • Adjustable pedal tensioner
  • 1 jack at the front: expression
  • In and Out jacks at the sides for volume (analog, 500K high-impedance)
  • Requires TRS-to-TRS cable when used as an expression pedal
  • Not spring-loaded

See the Product Guide and Layout Drawing for more information.

Expression pedal

Connect a pedal

The requirements for an expression pedal are:

  • linear resistance taper
  • max resistance of 10-100 kOhm
  • TRS-to-TRS cable connection (stereo jack)

From the Owners Manual:

TRS stands for TIP-RING-SLEEVE and describes the configuration of a 1/4" end plug or jack with three connectors. Normal guitar cables are TS (Tip-Sleeve) since they lack the ring required for a third contact. Expression pedals require TRS cables because full control voltage is transmitted to them on one contact (the tip), while less than full voltage is returned to on another (the ring) so the host device is able to sense and utilize the pedal position. The third contact (sleeve) is connected to ground.

Configure a pedal

Pedals which are connected directly to the Fractal Audio device can be configured and calibrated on the Pedal page of the Setup menu. On the VP4, this is the Setup > Pedals menu.

Pedals which are connected through another connected device, such as FC-6 and FC-12 foot controllers or MIDI controllers, must be configured in the configuration menu of that device, including calibration. For the FC controllers, use the FC controllers menu in the Setup menu.

Always calibrate the pedal before use. This makes sure that the pedal's full sweep range is being used.

You can assign the pedal directly to parameters in the preset. Or you can assign an External controller to that parameter, and then assign the pedal to that specific external controller. The latter option provides more flexibility.

What happens if the pedal is not connected

If a parameter is controlled by a switch or pedal, and that pedal or switch is not connected at startup, the processor needs to know what value to use. Disconnecting a pedal that operates as a Volume pedal should not mute the device, for example.

For parameters that have been assigned to an External controller, the desired initial value can be set in the Setup menu under Initial Value.

Current firmware also features activity sensing for internal pedals, FC pedals and external controllers. This stops Auto-Engage from activating an effect if the pedal/controller is not connected. This prevents, for example, a Wah being engaged if Auto-Engage is on but no pedal is connected (i.e., you left your expression pedal at home).

FRACTAL AUDIO QUOTES

[3] […] The expression pedal inputs on the Axe-Fx and on the FC6/12 have pullup resistors. If a pedal is unplugged the value goes to 100%. This is done so that if a pedal is connected to volume and you forget your volume pedal you'll still have sound.

Factory presets and pedals

Many factory presets let you use an expression pedal, for example as a Wah. Search the Factory presets page in the wiki for "External".

Create a volume pedal

To set up a volume pedal in a preset, read Volume/Panner block.

To set up a global volume pedal that works across all presets, read the section in the Owner's Manual.

Create a Wah pedal

Read Wah block for more information.

Create a Whammy pedal

Read Pitch block for more information.

Control the amount of Delay and/or Reverb

You can use an expression pedal to control the amount or delay or reverb. Assign the pedal as an External controller to the INPUT GAIN parameter in the Delay and/or Reverb Block.

Morph between clean and dirty tones

Watch the video below.

Display the tuner at heel down

Read Tuner for more information.

Auto-engage an effect

Read Auto-Engage for more information.

Use a pedal for multiple tasks

You can dedicate a single expression pedal to multiple tasks, within a single preset. Below are various examples to accomplish this.

Control either Wah or Whammy:

  1. Insert a Wah block.
  2. Insert a Pitch block, directly above or below the Wah in a parallel row. Connect it back to the main row.
  3. In the Modifier menu of BOTH effects (Wah:Frequency parameter, Pitch:Control) set Source to External 1. Enable Auto-Engage.
  4. Add a Mixer block to the main row, just after Wah and Pitch.
  5. Edit Mixer: enter the modifier menu of the Gain parameter for the row that connects to the Wah. Set Source to another External controller (which will be attached to an IA-switch to switch between Wah and Whammy). Set Start Value to 100% and End Value to 0.
  6. Do the same for the row that connects to the Pitch block. But: set Start Value to 0% and End Value to 100%.
  7. Program an IA switch to switch between Wah and Whammy, using the Mixer rows. Use the CC of the external controller that you specified while editing the Mixer block, and send "127" for the Wah, and "0" for the Whammy.
  8. Moving the pedal should activate both the Wah and the Pitch block. But thanks to the Mixer block you'll only hear one of these effects. If you're hearing the Wah and the Whammy effects simultaneously, you need to press the IA-switch to get the Mixer block to work.

Control Volume and Wah: (source: Bakerman)

  1. Place a Volume block on the grid.
  2. Assign an IA switch to an external controller's CC.
  3. Assign another external controller the Wah and Volume control knobs.
  4. Set the first external controller as a Bypass modifier for both blocks and reverse the slope of one (start 100, end 0).
  5. Now the IA switch will toggle between Wah/Volume and the pedal will control both.

Using Scenes and channels:

  1. Put Wah and Pitch and Volume in one vertical column.
  2. Assign an external controller (pedal) to the effects. Enable Auto-Engage in Wah and Pitch.
  3. Configure channel A, then copy it to channel B.
  4. In Wah and Pitch turn down Level in Channel B.
  5. Scene 1 is for Wah. Set Wah to Channel A, set Pitch to channel B, bypass Volume.
  6. Scene 1 is for Whammy. Set Wah to channel B, set Pitch to channel A, bypass Volume.
  7. Scene 3 is for Volume. Set Wah and Pitch to channel B, engage Volume.

Using the Multiplexer block:

Read Multiplexer block for more information.

Control Volume and Wah with an expression pedal that has a switch:

  1. Put the Wah and Volume blocks on the grid.
  2. Configure both blocks to be controlled by the pedal. Set the Wah to Auto-Engage.
  3. Attach the pedal's switch to the Bypass parameter of both blocks. Set Min/Max in the modifier menu in one block to 0/100 and in the other block to 100/0.
  4. The switch now switches between Wah/Volume duty.

External switch

Connect a switch

The FC controllers and FM3 support a dual-button switch per port when using a TRS cable, or a single-button switch when using a TS-TS cable.

The Axe-Fx III, FM9 and VP4 limit each PEDAL port to a single switch (TS cable).

Configure a switch

You can connect external switches to the device or to FC-6 and FC-12 foot controllers to expand switching possibilities. External switches can perform the same tasks as "local" switches on an FC controller, FM3 or FM9, like:

  • use Tap Tempo
  • engage the Tuner
  • switch Presets
  • switch Scenes
  • switch Channels
  • engage or bypass effect blocks
  • increase or decrease volume and save the preset
  • duplicate the function of onboard switches on the FM3, FM9 or FC controller
  • and more.

Configure the switch(es) in the Setup menu.

Switch Behavior 
determines how an external switch operates. With the default setting of "Follow Hardware" a switch behaves as you might expect. If you want a momentary switch to behave like a latching/toggle switch instead, use the "Virtual Toggle" option. Now, every time you tap the switch, its state on the Axe-Fx or FM3 will flip from ON to OFF, or OFF to ON. Note that if you accidentally apply the Virtual Toggle setting to a physical latching switch, you'll need to tap the switch twice for it to toggle.
Switch Polarity 
allows reversing the polarity of any connected switch. The option Normal assumes a momentary make switch. Use the option Reverse when using a momentary break switch, or for creative applications.

An external switch can operate globally as a copy of an onboard switch in any layout by assigning it as a Stand In switch. It's an exact surrogate for the onboard switch, and can even be used with per-preset functions. Momentary switches are preferred for use as stand-ins, because they more closely mimic the behavior of the on-board switches.

You can assign the switch directly to parameters in the preset. Or you can assign an External controller to that parameter, and then assign the switch to that specific external controller. The latter option provides more flexibility.

Scroll through presets

A single button switch, connected to the pedal port, can be used to scroll through the first bank of presets. This works fine if you have just a few presets to switch between. And if the processor has more than one PEDAL jack, you can assign one to increment and the other to decrement.

Engage and bypass an effect

To engage or bypass a specific effect, using an external switch, assign the switch to the effect block in the Setup menu.

Maintain bypass state when switching scenes

You can use an external switch to maintain the bypass state of an effect when switching through presets and scenes.

  1. Connect the switch.
  2. Assign the Bypass Mode parameter of the effect to the switch through an External controller.
  3. Repeat this in each preset which you want to control.
  4. Now the switch will control the effect's engaged/bypass state, regardless of the effect's saved state per preset or scene, and stay in sync.

Tips, tricks and troubleshooting

Pedal ports: ADC levels

Check the ADC (Analog-to-Digital Converter) levels of the pedal ports in the Setup menu.

Zipper noise

If moving the expression pedal creates choppy sounds or zipper noise, increase the Damping parameter in the modifier menu.

Pedal operates only for a part of the sweep

If an expression pedal only seems to operate for a part of its sweep, make sure that it's connected with a TRS-TRS cable and that it has been calibrated properly. Also, make sure that it really is an expression pedal and not a volume pedal.
