Priming Controls for Writing
Automation in Latch Mode
In Pro Tools 7.2, if a track is in Latch or
Touch/Latch automation mode, you can prime
individual controls for writing automation
while the transport is stopped. This Latch Prime
capability lets you prepare for an automation
pass before starting playback.
To prime controls for writing automation in Latch
mode while the transport is stopped:
1 Choose Setup > Preferences and click Mixing.
2 Under Automation, select Allow Latch Prime
in Stop.
3 Click OK to close the Preferences window.
4 In the Automation window, make sure the
controls you want to automate are write-en-
abled.
5 Click the Automation Mode selector on the
track where you want to write automation and
do one of the following:
• Choose Latch mode to allow priming of all
automation-enabled controls on the track.
• Choose Touch/Latch mode to leave the
main Volume fader in Touch mode and al-
low priming of all other automation-en-
abled controls.
6 While the transport is stopped, touch or move
the controls you want to start writing at the be-
ginning of the automation pass. When at least
one control on a track is primed, the Automa-
tion Mode selector displays in bold.
7 Start playback. All primed controls begin writ-
ing automation at their primed values.
8 Stop playback to finish the automation pass.
All tracks are taken out of their Latch Prime
state.
Taking Tracks and Controls Out of Latch
Prime
You can take individual tracks or automation
types out of their Latch Prime state before or
during an automation pass.
◆ When you take a track or automation type out
of Latch Prime before starting playback, it stays
in Latch mode but the corresponding controls
are not primed to write when playback starts.
In previous versions of Pro Tools, if a track
was in Latch automation mode, it was nec-
essary to touch or move a control after start-
ing playback to begin writing automation.

at the end of your automation pass to write
the current value back to the start of the
pass.
