*References to 4 mono (M3.1+1) or dual mono reflect the fact that the M3 allows separate material to be stored on the left and
right channels of a stereo pair. This configuration is typically used for material routed to different zones or an audio sync track. It

is important to note that the individual channels of a stereo pair are not able to be triggered independently. The L & R tracks run
simultaneously from a single trigger.
