The easiest way is to go into PERFORM mode and assign the “1-Button Looper” option to a footswitch:
Press once to record
Press again to play the loop
Press and hold to undo/redo
Double tap to stop playback
While the loop is stopped, press and hold to empty the loop.
You may also assign individual looper functions like Record, Play, Stop, Empty and UNDO/REDO to a footswitch in PERFORM mode. For these it’s best to assign them to an external aux switch or MIDI controller.
