for example), and then delete the selected events by pressing Delete.
For more information about similar and equal events, see Selecting Similar or Identical
Objects, Regions, or Events .
You can also delete events by choosing one of the Delete MIDI Events commands from
the Piano Roll Editor’s local menu bar.
To delete doubled events
µ
Choose Functions > Delete MIDI Events > Duplicates (or use the Delete Duplicated Events
key command, default assignment: D).
Any events occurring twice or more at the same position (and pitch) are deleted, allowing
one to remain.
Duplicated events may have different second data bytes (velocity, aftertouch, or controller
values). Logic Pro only looks at the event type and position when determining whether
or not two or more events are duplicated.
