2.5 Copy/Paste Functionality

The front panel of the 480 and 480R allow you to copy and paste the parameter value settings for entire effect module blocks, and then paste them into another block. Note that the information from one module must be pasted into a similar module, ie; from one dynamic module to another. This function can be performed in a single unit, or to any unit in a network setup. The procedure for cut and paste is as follows:

•From program mode, use the PARAMETER knobs to navigate to the desired module.

•Once the desired module has been selected, press and hold the PREVIOUS PAGE button until the display reads: COPY.

•The information is now held in what is commonly known as the “pasteboard.”

•At this point, navigate to the unit that you wish to paste the information into using the

PARAMETERS knobs.

•If you are pasting into a unit within the network, either enter in the device id# (key pad on the 480R, or from the Utility page in the 480).

•Once the desired module has been selected, press and hold the NEXT PAGE button and the display will read: PASTE.
