Choose automation modes in Logic Pro
Automation modes determine how automation tracks are treated. Automation is either
being read or being written. You can independently set the automation mode for each
track. You can also trim automation values and record relative automation data.
Read: Plays back all automation that exists on the track. If volume data exists,
for example, the Volume fader moves during playback, following the prerecorded
automation on the track. You can’t change the value of the chosen automation
parameter by moving controls when in Read mode. However, you can record region-
based information directly into a MIDI region in Read mode.
Touch: Plays back automation in the same way as Read mode. You can modify the value
of the chosen automation parameter by moving controls in Touch mode. After the fader
or knob is released, the parameter follows existing automation on the track.
Latch: Works like Touch mode, but after the fader or knob is released, the new
parameter value replaces existing automation on the track.
Write: Erases existing automation on the track as the playhead passes over it. Records
the new control movement or deletes the existing data if you do nothing.
Trim: Offsets the value of the existing automation (Volume, Pan, Send levels) by
adjusting it up or down by the amount you move the fader or control. Works in
combination with Touch and Latch automation modes.
Relative: Adds a secondary automation curve that offsets the existing primary curve for
the selected parameter (Volume, Pan, Send levels). Both the primary and secondary
curves are visible, and can be edited. Works in combination with Touch, Latch, and
Write automation modes.
Set the automation mode for a track
In Logic Pro, do one of the following:
Show the track’s automation curves, then choose a mode from the Automation Mode
pop-up menu in the track header.
Chose a mode from the Automation mode pop-up menu on a track’s channel strip.
Set the same automation mode for selected tracks
In Logic Pro, do one of the following:
Shift-click track headers to select them, then choose a mode from the Automation
Mode pop-up menu in one of the track headers.
Shift-click channel strips in the Mixer to select them, then choose a mode from the
Automation Mode pop-up menu in one of the selected channel strips.
