GLOBAL BYPASS -
The Global Bypass controller is a special type of bypass control. Whenever the
Axe-Fx receives a Global Bypass controller message it toggles the state of any effects that were
bypassed in the current preset. For example, if a preset has a Wah in it and that preset is saved with
the Wah in a bypassed state the Global Bypass message would un-bypass it. This controller can be
used as a universal master bypass control that toggles the bypassed blocks for each preset. Normally
you would have to remember what effect is bypassed in a preset and then send the appropriate
controller for that effect. With the Global Bypass, however, you can use a single controller to toggle
effects for each preset on and off. For some presets you may have a Drive block that you wish to
toggle on|off to switch between rhythm and lead work. For others you may have a Wah or Flanger
or whatever that you wish to toggle. So instead of having to use a different controller for each preset
you can simplify and just use one.
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.
