Automation : Automation Parameters : Automation with Audio and MIDI Clips
 
Automation with Audio and MIDI Clips
Track automation is handled differently for audio and MIDI.
Audio Tracks
On audio tracks, automation data is separate from audio clips.
MIDI and Instrument Tracks
On MIDI tracks and Instrument tracks, all controller automation data, except for MIDI Mute data or audio mute (Instrument tracks only), is stored in the MIDI clip that contains it.
