The Max Dots parameter affects the rhythmic display of dotted notes (notes that are one-and-one-half times as long as the equivalent undotted note value) by controlling the maximum number of dots that can be displayed. This makes the display of such notes less metronomically precise, but makes the score more readable. By default, the number of Max Dots is 1.
Unwanted dotted notes or rests can be changed by inserting user rests (which remain invisible, if notes). See Use tuplets to override display quantization for information on changing the way notes with ties are displayed).
Set the maximum number of dots
In the Region inspector, do one of the following:
