The Mute and Delete functions go hand in hand, because you will often want to remove events you have muted.
Select one or more note events, then choose Functions > Mute Selected Events on/off (default key command assignment: M).
A dot appears in the Status column of muted note events.
The Edit > Select > Muted Events command is also available in the Event List. It can be used to quickly select and delete all muted events.
Do one of the following:
Select the events, then press Delete.
Choose one of the commands in the Edit > Delete MIDI Events menu.
Duplicates (default key command assignment: D): Erases all duplicate events.
Inside or Outside Locators: Erases all MIDI events inside/outside the locators.
Outside Region Boundaries: Erases all MIDI events that fall completely outside the region borders, which can happen when regions are resized.
Unselected Within Selection: Erases all unselected MIDI events within a selection, such as between locators.
