Rikki - not sure, but every time you press the Assignable button you toggle it one way or the other and the display reflects the status. Seems like there are many functions that are assignable w/the 6 buttons to eliminate button sequences. I think you can also assign many of the "Assignable" functions to the Live Control knobs or a pedal as well. And apparently you can have "sets" of Assignable settings....still checking that.
