Swing Swing provides the 'feel' associated with jazz by altering the timing of pairs of notes of equal value. The second note of the pair normally starts halfway through the total time of both notes; however, changing Swing shifts the second note's start point to the specified percent of the total note pair duration. For example, changing Swing to 75% causes the second note of the pair to start 75% of the way through the total note pair duration. Note that this field is ignored when quantizing by groove.
