	# The APC 40 out-of-the-box is great for performing, but less useful for producing because it lacks
	# frequently used functionality such as Undo/Redo (doh, made a mistake) or deleting clips, for which
	# you are forced to go back to mouse and keyboard.
	#
	# This example AppleScript shows how to use MidiPipe to re-configure the AKAI APC 40 mk2 MIDI controller
	# to execute Undo (Cmd-Z) and Redo (Shift-Cmd-Z) in Ableton Live with the controller's 'NUDGE -' and 'NUDGE +'
	# buttons, respectively, instead of nudging the tempo.
