The Utility section contains all of the menus for assigning global functions to the GNX4. Global functions
affect the GNX4 in its entirety rather than on a per preset basis.The Utility menus include: Volume Pedal
Update,V-Switch Threshold,Expression Pedal Calibration,Bounce-Back, Bank Naming, MIDI Channel,MIDI
Sysex Dumps,Amp Dumps,MIDI Mapping,MIDI Merge,and Factory Reset. To enter the Utility section, press
the UTILITY button. Once in the Utility menu,the NEXT button selects the next menu (scrolls to the
right),and the PREV button selects the previous menu (scrolls to the left).Each of these Utility menus is
described in more detail in the following pages.
Volume Pedal Update
The GNX4 lets you select the Expression Pedal’s position to be updated, after changing presets,when it is
linked to the Volume Parameter. This feature lets you change presets and keep the volume level from the
previous preset,if the Expression Pedal controls the volume for both presets. If this feature is disabled,
new presets are set to the volume level value stored with the preset.The procedure for enabling or
disabling the Volume Pedal Update is as follows:
1.Press the UTILITY button. The button will light indicating you are in the Utility menu.
2.Use the PREV or NEXT buttons to select
volumpdl (Volume Pedal Update) is displayed.
3.Rotate the DATA WHEEL to select On (enabled),or OF (disabled).
4.When finished, press EXIT.
V-Switch Threshold/Sensitivity
Applying extra pressure to the toe of the Expression Pedal engages a feature called V-Switch. V-Switch is
used to alternate between controlling assigned Parameter(s) with the pedal,and using the pedal as a Wah
pedal.The sensitivity of the V-Switch can be set to the amount of pressure you want to use. The following
steps explain how to set the V-Switch Threshold:
1.Press the UTILITY button.The button will light indicating you are in the Utility menu.
2.Use the PREV or NEXT buttons to select
vSWItCH (V-Switch).
3.Rotate the DATA WHEEL to select the threshold setting. Ranges are from
0 to 99, then off (Of) to
disable (with 99 requiring more pressure to engage). The sensitivity may be auditioned while making
adjustments. Use the V-Switch LED as an indicator of the switching status.
4.When finished, press EXIT.
Expression Pedal Calibration
The Expression Pedal on the GNX4 needs to be recalibrated for use after a factory reset has been
performed. This calibration procedure is automatically activated after a factory reset procedure. In the
event the pedal’s calibration fails, or if the pedal does not function properly, it can be re-calibrated using
the Pedal Calibration menu. The procedure for Calibrating the Expression Pedal is as follows:
1.Press the UTILITY button. The button will light indicating you are in the Utility menu.
2.Use the PREV or NEXT buttons to select
pedalcal (Expression Pedal Calibration).
3.Press the flashing STORE button to enter the Pedal Calibration Menu.The display will read

(Toe Down).
4.Rock the Expression Pedal all the way forward to the toe down position and press the blinking number
4 Footswitch.The display changes to read
TOE UP (toe up).
5.Rock the Expression Pedal all the way back to the toe up position and press the blinking number 5
Footswitch.
VSW cal is displayed and allows you to adjust the V-Switch Threshold.
6.Rock the Expression Pedal forward and apply the V-Switch pressure to the toe of the pedal. If further
adjustment to the threshold is required,use the DATA WHEEL to select the threshold.
NOTE: If the Display shows
