Inserting and Editing Controller Events
Continuous controller events can b edited with any of the following methods:
*   
Individual breakpoints can be dragged with any Grabber tool to adjust their location or value.
*   
A group of selected breakpoints can be scaled up or down with any of the Trim tools.
*   
New controller events can be drawn in with the Pencil tool to replace existing events. Events can be drawn with the Pencil tool (set to Free Hand, Line, Triangle, Square, or Random).
*   
Controller events can be cut or copied and pasted, as well as nudged or shifted.
*
To copy continuous MIDI controller events and paste to a different MIDI controller, use Special Paste (Edit > Paste Special > To Current Automation Type). For example, you might want to use the same control data for volume and a cut-off filter, or for pan and pitch bend. For more information, see Special Paste Function for Automation Data.
*
Edits to volume data affect all tracks within an enabled Edit Group. This is not the case, however, for other controller playlists (such as pan). To insert and edit other controller types across all tracks in an Edit Group, press the Start key (Windows) or Control (Mac) while performing the edits.
