Separating MIDI Notes
The Separate command lets you separate MIDI notes at the Edit cursor location or at the boundaries of the Edit selection. When in Notes view in the Edit window and in the MIDI Editor, separating MIDI clips creates new MIDI notes but does not create new MIDI clips. However, when in Clips view in the Edit window, separating MIDI clips only creates new MIDI clips. Also, if the Edit selection includes any audio tracks, the Separate command separates only clips on MIDI and Instrument tracks regardless of the Track View setting.
To separate MIDI notes at the Edit cursor location or at the boundaries of the Edit selection:
1. Make an Edit selection or place the Edit cursor at the location where you want to separate one or more MIDI notes.
2. Do one of the following:

Choose
Edit > Separate > At Selection.

Right-click in the Notes pane and choose
Separate.

Press Command+E (Mac) or Control+E (Windows) to separate MIDI notes at the selection.
To separate MIDI notes on the grid:
1. Set the Grid value.
2. Make an Edit selection or a marquee selection that includes the MIDI notes you want to separate.
3. Choose Edit > Separate > On Grid.
4. In the Pre-Separate Amount dialog, click OK.
