Switching Tones Without Interrupting the Sound
Using DIVIDER and MIXER within the same memory
Place the same type of effect in parallel and use DIVIDER to switch between channels A and B.
Example:
Switching from a clean sound that uses chorus and heavy delay to a high-gain, crunchy sound that uses a phaser and light delay.
The settings of the effect used before switching are placed in parallel with the settings used after switching.
Preserving the Tail of the Effect (Delay, Reverb, etc.) when the Effect is Switched Off (Carryover)
The function that preserves the tail of an effect (such as delay or reverb) even after the effect is switched off is called “carryover.”
Enabling carryover when switching memories
To enable the carryover of the delay or reverb (included in the memory that you used before switching) after you’ve switched to a
different memory, make the following settings.
● On the preceding and on the following memories, configure the effect chain to use the same effect, and use the same
arrangement. Set each effect type to be the same as well.
● On each memory, change the effect parameter settings and the on/off settings.
● Turn the CARRYOVER parameter in MASTER of the final component in the effect chain to “on.”

Virtual Expression Pedal System (Internal Pedal / Wave Pedal)
By assigning a desired parameter to the virtual expression pedal, you can produce an effect as though you were operating a
physical expression pedal to change the volume or tone quality in real time.
The virtual expression pedal system provides the following two types of functions, and you can use the SOURCE setting for ASSIGN
1–20 to choose the desired type.
Internal pedal
If SOURCE is set to “INT PEDAL,” the virtual expression pedal will begin operating when started by the specified trigger (TRIGGER),
modifying the parameter specified by “TARGET”.
Wave pedal
If SOURCE is set to “WAVE PDL,” the virtual expression pedal will cyclically modify the parameter specified by TARGET in a fixed
wave form.

Adjusting the Expression Pedal (Pedal Calibration)
Although the GX-100’s expression pedal has been set for optimum operation at the factory, extended use and the operating
environment can result in the pedal going out of adjustment.
If you encounter problems such as being unable to fully cut off the sound with the volume pedal or being unable to switch the
PEDAL FX, you can use the following procedure to readjust the pedal.
1.
Press the [MENU] button.
2.
Touch <HARDWARE SETTINGS>.
3.
Touch <PEDAL CALIBRATION>.
The PEDAL CALIBRATION screen appears.
4.
Press the heel end of the pedal, and press the [WRITE] button.

The screen will indicate “OK,” and then a screen like the following will appear.
5.
Press the toe end of the pedal, and press the [WRITE] button.
The screen will indicate “OK,” and then a screen like the following will appear.
6.
Strongly press the toe end of the pedal.
Verify that the PEDAL FX indicator lights when you strongly press the toe end.
If you want to change the lighting sensitivity of the PEDAL FX indicator, repeat step 4 while you adjust the THRESHOLD value
with knob [4].
7.
Press the [WRITE] button.
The screen will indicate “COMPLETED!”
* When you operate the expression pedal, please be careful not to get your fingers pinched between the movable part and
the panel. In places where small children are present, make sure that an adult provides supervision and guidance.

Looper
70
Looper
You can record a performance and play back the recorded section over and over (mono: up to 38 seconds, stereo: up to 19
seconds). You can also layer additional performances (overdubbing) with the recording as it plays back.
This lets you create real-time backing performances on the fly.
You must place the looper somewhere in the effect chain in order to use it.
Also, you need to assign the looper’s record, play, and overdub functions to the switches you want. Here’s an example of how you
can use the [C1] switch on this unit or an external footswitch connected to CTL 3, 4/EXP jack on this unit to operate the looper.
Placing the looper in the effect chain
1.
Select the memory with which you want to use the looper.
2.
Follow the steps in “3.2. Effect Placement(P.26)” to place the looper in the effect chain.
Assigning Looper Functions to Switches
1.
Follow the steps in “8.1. Assigning a Function(P.49)” to display the CONTROL FUNCTION screen.
2.
For “CTL 1,” ”CTL 3,” and ”CTL 4,” set FUNCTION as follows.

Loop Playback Level Setting
If you set the playback level at 100 (default value), the volume of the performance and that of the loop playback will be identical.
If you set the playback level to a value lower than 100, the volume of the playback will be lower than that of the performance. As a
result, the sound of the performance won’t get buried by the loop playback sound, even if you record a multiple number of times.
1.
Following the steps in “3.1. Basic Procedure for Effect Editing(P.23),” touch the “LOOP” icon on the effect
chain screen.
2.
Turn knob [1] to specify the “PLAY LEVEL” value.
