Now that you’ve nished with preparations, here’s how to operate the GR-55 while you play.
Adjusting the Output Level
1.  Adjust the GR-55’s output level by turning the [OUTPUT LEVEL] knob.
Turning the knob toward the right will increase the volume;  
turning the knob all the way toward the left will set the volume to zero.  
Normally, you can place the knob near the center position.
Step on the expression pedal.
Raise the GK pickup’s volume knob.
Selecting a Sound (Patch)
What is a Patch?
A “patch” is a unit of sound on the GR-55; in addition to settings 
determining the type of sound, the patch also includes eect 
settings.
You are free to modify (edit) the settings of a patch and store it in 
the GR-55 as a “user patch.” (Patches that are already built into the 
GR-55 are called “preset patches.”)
For more about patches, refer to “How the GR-55 Works” (p.22).
What is a Bank?
A “bank” is a collection of three patches.
What is a Sound Style?
The GR-55 lets you select preset patches from three “sound 
styles.” First select the style of sound that you want to play, and 
then select a patch from within that style.
