Section Five - Other Functions
Expression Pedal
The Expression Pedal on the GNX1 can be assigned to control up to 3 Parameters in real time including the Volume,
Whammy™,Ya Ya™, or just about any other parameter.. When a parameter has been assigned to the Expression Pedal,
the minimum and maximum values the assigned Parameter will reach can also be programmed.The GNX1’s Expression
Pedal includes DigiTech’s exclusive V-Switch.The V-Switch allows the Expression Pedal assignment to be switched on the
fly. Applying extra pressure to the toe of the Expression Pedal will engage the V-Switch and the function of the
Expression Pedal will switch between the assigned parameter and Wah. The sensitivity or amount of pressure required
to engage the V-Switch can be adjusted to suit your personal taste (or weight of your foot). See page 35 for the V-
Switch Sensitivity adjustment procedure.
The procedure for assigning a parameter to the Expression Pedal is as follows:
1. Press the Effect Select button until the Exp Assign row has been selected.
2. Press the Status button until the Display reads
EXPDL1
(Expression Pedal Link 1),
EXPDL2
(Expression Pedal Link
2), or
EXPDL3
(Expression Pedal Link 3), depending upon which assignment you wish to use or the number of
Parameters you intend to assign.The Display will alternate between showing the Expression Pedal selection and the
currently assigned Parameter.
3. Rotate the Number 1 Knob until the desired Parameter appears in the Display. See the Expression Parameter
Assignment List on page 33 for a complete list of assignable Parameters.
4. Rotate the Number 2 Knob to select the minimum value the assigned parameter will reach with the Expression
Pedal in the toe up position (not available when volume is the assigned parameter).
5. Rotate the Number 3 Knob to select the maximum value the assigned parameter will reach with the Expression
Pedal in the toe down position (not available when volume is the assigned parameter).
6. Store your Expression Pedal assignment to your Preset. See page 17 for more information on the storing procedure.
LFOs
The GNX1 includes two assignable low frequency oscillators (
LFO1
and
LFO2
) which can be assigned to any of the
same parameters available for assignment to the Expression Pedal. A low frequency oscillator will automatically vary the
value of the assigned parameter at a steady rate. A minimum and maximum value each LFO will reach may be also be
assigned. For instance: if the Amp Gain was assigned to
LFO1
, and the minimum value was set at 1 and the maximum
value was set at 99, the GNX1 would automatically sweep the amount of distortion from a clean sound to a distorted
sound. Individual LFO speeds are also available for assignment. In the previous example, the LFO speed would
determine the length of time it took the LFO to sweep from the clean to the distorted sound.The procedure for
assigning the LFOs in the GNX1 is as follows:
1. Press the Effect Select button until the Exp Assign row has been selected.
2. Press the Status button to select whether you want to assign
LFO1
(LFO1) or
LFO2
(LFO2).
3. Rotate the Number 1 Knob until the desired Parameter appears in the Display. See the Expression Parameter
Assignment list on page 33 for a complete list of assignable Parameters.
4. Rotate the Number 2 Knob to select the minimum value the assigned parameter will reach at the bottom turn
around point for the LFO (not available when volume is the assigned parameter).
5. Rotate the Number 3 Knob to select the maximum value the assigned parameter will reach at the top turn around
point for the LFO (not available when volume is the assigned parameter).
6. Rotate the Number 4 Knob to select the speed at which the LFO will oscillate from the minimum to the
maximum values. LFO speed ranges from
.O5 HZ
(.05 Hz) to
1ºO HZ
(10.0 Hz).
7. Rotate the Number 5 Knob to select the waveform the LFO will oscillate on.Your choices include:
TRINGL
(Triangle) - a smooth rise and fall, but abrupt turn around in oscillation.
SINE
(Sine) - a smooth rise, fall, and turn around in oscillation.
SQUARE
(Square) - an abrupt rise, fall, and turn around in oscillation.
8. Store your LFO assignment to your Preset. See page 17 for more information on the storing procedure.
