When a logic connection has been assigned as a logic output in the Setup Menu (CL-1: Logic Out Assign), it cannot also be assigned as an input until removing its output assignment.

7-Series users can assign specific functions to the Logic I/O pins of a CL-1 through the Setup Menu option EXT Keyboard: Assign. This includes all transport controls and most menu functions. If you are experiencing difficulty getting one of your Logic inputs to function properly, check to make sure the pin is not already assigned as an output.
