Previewing Automation
(Pro Tools HD Only)
Automation Preview mode lets you audition
changes to a mix and compare them to existing
automation values without committing them to
the automation playlist.
When you put Pro Tools in Automation Preview
mode, you can preview values for automation-
enabled controls on any track that is in a writ-
able automation mode.
While in Automation Preview mode, when you
touch or move a control, it isolates the control,
disengaging it from its automation playlist. The
control stops reading or writing automation, al-
lowing you to freely audition changes.
When you have found a level or state that you
want to use, you can then commit or punch the
previewed value to the automation playlist for
the isolated controls.
‹ If you punch during playback, the automa-
tion mode is set to Latch and writing begins at
the preview value.
‹ If you punch while the transport is stopped,
the automation mode is set to Latch and the
control is primed at the preview value.
Previewing New Automation

preview is enabled in the Automation window
(Volume, Pan, Mute, Send level, Send pan, Send
