MIDI Editing
For more information, see the following topics:
Pro Tools provides powerful MIDI editing tools. You can create and edit individual MIDI notes and controller events with the Pencil, Trim, and Grabber tools in the Edit window, MIDI Editor windows (see MIDI Editors), and the Score Editor window (Score Editor).
You can use the various Event Operations (such as Quantize, Transpose, Change Velocity, and Change Duration) to destructively transform groups of MIDI notes in terms of pitch, timing, dynamics, and phrasing (see Event Operations).
Additionally, you can use Real-Time Properties to nondestructively affect MIDI on playback or play-through (see MIDI Real-Time Properties).
Pro Tools also provides numerous zoom and view tools that are optimized for MIDI editing.
