Getting Set Up

When a preset is recalled the effects are in the bypass state that they were stored in. Any that are
bypassed may then by activated using either their individual bypass controllers or all may be
activated by using the Global Bypass.
EFFECT BYPASS -
Each effect in the Axe-Fx can be toggled in and out of bypass using a MIDI
continuous controller. Following the Global Bypass item are the individual bypass controllers.
Simply set the value to the desired controller number (or pedal number).
Example
To control the bypass state of Flanger 1 use the navigation buttons to select FLANGER 1
BYP. Then turn the value knob (or press ENTER to automatically learn) to select the
desired controller number. In this example we’ll use CC# 12. Now whenever the Axe-Fx
receives a CC# 12 message the bypass state of Flanger 1 will be set to the value of the
controller.
Note that the Axe-Fx uses negative logic for the bypass state. A controller value of zero bypasses
the effect and non-zero the effect is active. So if the controller value equals zero, effect off,
controller value greater than zero, effect on.
Pedal Configuration
The
PEDAL
page configures the pedals. The pedals can be used for parameter control, volume
control, effect bypass, preset switching and other purposes. When used for preset switching the
Axe-Fx can change presets without the use of a MIDI controller.
The two pedal jacks on the back of the Axe-Fx support continuous, momentary or latching pedals.
Continuous pedals are normally used for real-time continuous control of effect or global parameters
(i.e. volume). The other types are normally used for bypass control or preset switching. It is
important to understand how the various pedal modes operate to use them to the ultimate capability.
To use the pedal for switching operations such as bypass or preset change be sure to set the pedal
type to match the type of footswitch. Momentary footswitches close a contact while the pedal is
depressed. They typically do not "click" when pressed. Latching footswitches alternate between
contacts closed and opened each time the switch is depressed, they usually click.
Internally the Axe-Fx stores a state for the pedal. For momentary footswitches depressing the switch
toggles the internal state between 0 and 1. When set to latching the state of the contacts sets the
internal state: contacts closed = 0, contacts open = 1.
Footswitches are normally used to control an effects bypass state or for preset increment/decrement.
Of course one can still assign a footswitch as an external controller but the "value" from the switch
will be either 0 or 1. This may be used, for example, to change the rate of a Rotary simulator
between two speeds, when the controller is at value 0 the rate would be slow and when at 1 the rate
would be fast. This would be setup using a modifier on the Rotary simulator rate control.
When using a footswitch to control preset recall, a change of state causes a preset change. For
example, if a momentary footswitch is connected depressing the switch toggles the internal state.
This in turn would increment/decrement the current preset if configured as such. However, if a
