How can I save (backup) all of my PC4 user data and system settings?


The PC4 saves all data from both User Banks (Program and Multis) into one file with a “.PC4” extension. PC4 files can be saved/loaded to/from a USB flash/thumb drive.

“STORE” Procedure:

1) Plug a flash/thumb drive into the PC4 back-panel USB “Storage” port:
2) Press the front panel GLOBAL mode button:
3) Press the soft “FILE” button:
4) Press the “STORE” soft button:
5) Press the “ALL” soft button:
6) Select the directory to save your file to. The simplest approach here is to just press “OK” to store your file to the current directory:
7) Name your file. Use the alpha wheel and/or alphanumeric keypad to enter characters. Use the soft buttons beneath the display to move the cursor and manage character positions. Then press “OK” to save the file to disk:

8) A brief “Storing…” message will be displayed while the file is saved. Once completed you will return to the Storage mode screen.


9) Press Exit or any of the mode buttons (Program, Multi or Global) to leave File mode.

  • If no flash/thumb drive or USB cable is inserted when pressing “STORE” (step 4), the display will show the message “Error: No valid device inserted.”.
  • If the filename you choose already exists on disk, when pressing “OK” (step 7) you will see an alert. “Warning: A file with that name already exists. Are you sure you want to overwrite it?”. You can choose ‘Yes’ to proceed, or ‘No’ to return to the naming screen and enter a new name.
  • If no USER objects are in memory when pressing “OK” (step 7), the display will show the message “Nothing stored”.
