Chapter 21: Automation 309
Adding Snapshot Automation to
Empty Automation Playlists
When you use the Write Automation com-
mand on an automation playlist with no
previously written automation data, the se-
lected value is written to the entire playlist
and not just the selected area.
This is because a playlist with no automa-
tion data contains only a single automa-
tion breakpoint that corresponds to the
current position of the control. The posi-
tion of the breakpoint is updated whenever
the parameter value is changed.
If you do not want the Write Automation
command to write the selected automation
value to the entire playlist, you can:
Anchor the automation data by placing
the cursor at the end of the session (or any
other endpoint) and choosing Write Auto-
mation To Current Parameter.
– or –
Click with the Grabber on each side of
the selection.
This allows the Write Automation com-
mand to write only to the selected area.
Writing Snapshot Automation over
Existing Automation Data
When you move the playback cursor, the
automated controls in Pro Tools update on
the screen to reflect the automation data
that is already on the track. To keep the set-
tings you have made for a snapshot, you
can suspend the desired automation pa-
rameters to prevent the controls from up-
dating.
To write snapshot automation over existing
data:
1 In the Automation Enable window, make
sure that the automation parameters you
want to edit are write-enabled. Disable any
parameters you want to preserve.
2 Adjust the controls for the parameters
you want to automate.
3 Suspend the automation parameters you
want to automate:
For an automation parameter on a single
track, Command-click (Macintosh) or
Control-click (Windows) he name of the
automation type in the track’s Display
Format Selector.
For an automation parameter on all
tracks, Command-Shift-click (Mac-
intosh) or Control-Alt-click (Windows)
the name of the automation type in the
Display Format Selector for any track.
To suspend all automation on a track,
Command-Shift-click (Macintosh) or
Control-Shift-click (Windows) the name
of the automation type in the track's Dis-
play Format Selector.
4 With the Selector, select the location
where you want to apply the automation.
5 Enable the automation parameters previ-
ously suspended.
6 Choose Edit > Write Automation and se-
lect one of the following from the sub-
menu:
To write the current value to only the au-
tomation parameter currently displayed
in the Edit window, choose To Current
Parameter.
To write the current settings for all auto-
mation parameters enabled in the Auto-
mation Enable window, choose To All
Enabled Parameters.
