The Algorithm you choose for a Program determines the basic function of the Program, so make
sure you choose an Algorithm that has all the Modules you want to use in an appropriate config-
uration. The Algorithm selection screen for each Program can be found one screen to the right
(one Parameter [NEXT] keypress) from the Program's Title Screen

The Algorithm selection screen works in conjunction with the LED display to show other infor-
mation about the Algorithm. When you change a Program’s Algorithm assignment, the LED
display shows whether the currently selected Algorithm is a factory Algorithm or a user
Algorithm, and the Algorithm’s number in memory. Factory Algorithms are indicated by an “F”
in the LED display, followed by a number. User Algorithms are indicated by a “U” in the LED
display, followed by a number. To select an Algorithm for a Program, do the following:

• From the Program Title screen, press the Parameter [NEXT] key once. This is the

Algorithm selection screen. The top line of the display tells you the number of the
currently selected Algorithm, whether it is a factory or user Algorithm, and the name
of the Algorithm. The bottom three lines show the Modules in the Algorithm. If you
change the Program’s Algorithm assignment, the LED display changes to show either
a "U” for User, or an “F” for Factory, followed by the number of the newly selected
Algorithm.

NOTE: When there are more Module names in the Algorithm than will fit on the bottom two 

lines of the display, an arrow will appear in the first or last character of the display. 
These arrows indicate that there is more information about the Modules that could not
be displayed on a single screen. To see the remaining information, simply press the 
Parameter [NEXT] or [PREV] key (depending on the arrow direction indicated in the 
display).

• Use the Data wheel to select the Algorithm you want to use with the Program. Note

that when you change the Program’s Algorithm assignment, the Program must be
stored to retain the changes you've made. See pg. 17 for storing procedures.

Once you’ve selected the Algorithm you want to use, you can begin modifying the Parameters.

The [TEST] button allows you to listen to individual effects Modules by themselves. This can
help you decide which FX Modules you want to include in your User Algorithms. The
Parameter settings for the GSP-2101 Artist [TEST] sounds are basic, general-use sound settings
only, and have a 50:50 wet/dry mix. 

To listen to an individual effect Module, do the following:

• Press the [TEST] button from anywhere in the Parameter menu or from the title

screen. The display reads:

Select Fx module for
sound test.
