Choosing Automation Modes
You can choose from the following automation modes in any channel strip:
Off
Off disables the current track automation data without deleting it. No automation data
is written, read, or played back. If the current automation mode is Off, any edits to track
automation data in the Arrange area automatically switch the automation mode to Read.
This ensures that the data, as currently edited, will be played.
Given that track automation can be recorded during playback mode, Off is the default
setting, as any mix automation recording may prove disconcerting while arranging.
Read
Read mode automates the current track, using the existing automation data.
The data cannot be changed by moving the channel strip controls, or using an external
automation controller, when in Read mode.
Touch
Touch mode plays back automation data in the same fashion as Read mode.
