GR-55: USING THE ASSIGNS
Knowledge Base Id: 23460471


In the GR-55,  you can assign or "TARGET" various parameters to be controlled, such as;  ON/OFF switches for the tones and effects, effects levels, etc.. These targeted parameters can be controlled by what is called a "SOURCE." A Source can be a button, footswitch, or pedal on the GR-55, or even an external pedal on a midi controller for additional control and functionality.

There are 8 available Assignments in each patch in the GR-55. Here's how to setup an assignment. For this example we will setup ASSIGN 1 so that the CTL pedal turns on and off the delay effect:     

1. Choose a patch to edit. 

2.  Press the EDIT button. 

In this view you will see four tabs: TONE, EFFECT, MASTER, SYSTEM. The PAGE [? ?] buttons allow you to access and move between the different tabs.

3. Press the PAGE [? or ?] button to select the MASTER tab.   

Tip: Once you've selected a tab,  you can use the dial and/or  the ??? ? cursor buttons to navigate through the parameters.

4. Turn the dial to highlight the ASSIGN icon and then press ENTER.  In the ASSIGN menu there are eight tabs (numbered 1-8). Each tab is an ASSIGN.

5. Cursor to highlight "SWITCH" and then turn the dial to choose "ON." This turns on  ASSIGN 1.

6. Press cursor down to highlight "TARGET."

7. Turn  the dial to select "DELAY TYPE SWITCH." This is the ON/OFF switch for the delay effect.

8. Press cursor down once to highlight  "TARGET MIN."  By default it should be set to "OFF."  If not, turn the dial to select  "OFF."

9 Press cursor down once to highlight  "TARGET MAX,"  and then turn the dial to select "ON."

The TARGET MIN/MAX settings specify the range of change for the specified TARGET parameter. Depending on the TARGET you chose,  you will see different ranges displayed between the MIN/MAX. Some are as simple as OFF and ON others can be millisecond variation from 5ms-3400ms or 0-100. These variables are dependent on the TARGET.

10. Press cursor down to highlight "SOURCE." As explained previously, the SOURCE is the button, foot switch, pedal, controller or midi CC# that you want to assign to control the parameter you chose for the TARGET. Remember, for our example we are choosing the CTL pedal as our SOURCE and it is controlling the ON/OFF switch of the delay.

11. Turn the dial to select "CTL." 

12. Press cursor down to highlight "SOURCE MODE," and then turn the dial to select "TOGGLE."  There are two choices here:

TOGGLE:  When you press and release the pedal, the Target function will activate and stay activated until you press the pedal again. Thus - "toggling" between On and Off. 

MOMENTARY:  When you  press on the pedal, the Target function will activate and stay activated  for long as you keep your foot presseddown on the pedal. As soon as you release the pedal,  the switch is deactivated. Thus - only engaging the pedal for the "moment" your foot is holding the pedal down.



The last two choices are ACT RANGE LO / ACT RANGE HI and are generally kept at the default range of 0 and 127. An example of wanting to adjust these would be if the throw of the expression pedal physically is too long for you, and you want to shorten the effect range between the heel down and toe forward positions.

13. Press the EXIT button twice to return to the main screen.



To view the function of the new assignment;

1. Press EDIT.

2. Press PAGE [? ?]  to select the EFFECT tab.

3. Press the CTL pedal  to turn the DELAY ON/OFF. Notice the switch (box) in the lower left corner. When it's solid, the delay is on. When it's empty, the delay is off.

If you want to save the new settings to a patch, press the WRITE button twice.

GR-55: WRITING (STORING) USER PATCHES
Knowledge Base Id: 23684931

If you edit a patch in the GR-55, you must save (write) that patch to a user location if you want to keep the settings. If the patch does not get written into a user memory, all of the edits/changes that you've done for that patch will not be saved. Here's how to Write a patch in the GR-55.

1. Edit any patch to your liking.

2. Press the WRITE button.

3. Turn the dial to choose a User location to write to.

4. Press WRITE again. ("Now Writing" appears briefly in the display and then you're returned to the main menu).

GR-55: CALIBRATING THE EXP PEDAL
Knowledge Base Id: 26848503


The GR-55 contains a pedal calibration feature which can be used to calibrate the on-board EXP pedal. This can be used if the EXP pedal is not functioning as expected, even after you've assigned the correct parameters to it.

Tip: Performing the pedal calibration will not erase or affect any patch or system parameters in the GR-55.

1. Press EDIT.

2. Press the PAGE right (>) button to access the SYSTEM tab.

3. Turn the dial to highlight the BACKUP/INIT icon.

4. Press ENTER.

5. Turn the dial to highlight the PEDAL CALIB  icon, and then press ENTER.

6. Move the EXP pedal to the minimum (heel back) position - as described in the display.

7. Press ENTER - "OK" appears briefly in the display.

8. Press the EXP pedal all the way toe-forward until it stops.

GR-55: USER PARAMETERS NOT SAVING WITHIN A PATCH
Knowledge Base Id: 22611372

Some of the factory Preset patches in the GR-55 have the CTL pedal and/or EXP SW assigned to control various functions, for example, the PCM Tone On/Off switch.

An assignment of this nature can make it appear that User parameters are not being stored in a patch. To turn off the pre-assigned CTL and/or EXP SW functions, follow these steps.

1. Select the desired User patch.

2. Press the EDIT button.

3. Press PAGE left or right to select the MASTER tab, and then press ENTER.

4. Cursor left to "PEDAL/GK CTL," and then press ENTER.

5. Cursor down to "CTL FUNCTION," and then turn the dial counterclockwise to select "OFF."

6. Press PAGE right to select the EXP SW tab.

7. Cursor down to "EXP SW FUNCTION," and then turn the dial counterclockwise to select "OFF."

8. Save this new setting into the patch by pressing WRITE twice.

Note: Some patches may also contain assignments in the ASSIGN section that can effect custom stored parameters. If the above steps don't help with your patch, go to the ASSIGN men, turn off each assignment in the patch, and then save the settings.
