The Duplicate command copies a selection and places it immediately after the end of the selection. Though this is similar to using
Copy and
Paste,
Duplicate is more convenient and faster, particularly when working with data on multiple tracks.
As with the Copy and
Paste commands, certain rules apply when duplicating material on multiple tracks (see
Editing Across Multiple Tracks).
In Shuffle mode, the duplicated data is placed directly after the end of the selection. Clips occurring after it slide to accommodate the duplicated material. In Slip mode, the duplicated material overlaps any adjacent data.
When using Duplicate (or
Repeat) with MIDI notes that were selected with the Time Grabber tool, material is always duplicated one measure later, and is merged with existing track material (instead of replacing it).
