Writing Automation
You can write automation for all automat-
able controls by moving those controls
during playback.
To write automation on a track:
1 In the Automation Enable window, make
sure the automation type is write-enabled.
2 Choose an automation mode for each
track you want to automate. For an initial
automation pass, choose Auto Write.
3 Click Play to begin writing automation.
Move the controls you want to automate.
4 When you have finished, click Stop.
After the first automation pass, you can
write additional automation to the track
without completely erasing the previous
pass by choosing Auto Touch mode or Auto
Latch mode. These modes add new auto-
mation only when you actually move the
control for that parameter.
To write additional automation to a previous
pass:
1 In the Edit window, make a selection or
place the cursor in a location where you
want to write automation.
2 Choose Auto Touch or Auto Latch mode
on the tracks you want to automate.
3 Click Play to begin writing automation.
Move the controls you want to automate.
4 When you have finished, click Stop.
✽ If you write automation in Auto Touch mode
with Loop Playback enabled, writing of automa-
tion will automatically stop at the end of the
looped selection. At the beginning of each suc-
cessive loop, you can then touch or move the
control again to write new data.
Storing an Initial Controller Position
When you create a new audio track, Auxil-
iary Input, or MIDI track, it is automati-
cally placed into Auto Read mode. Even
though the track is in Auto Read mode, you
can set the initial position of any automat-
able control, and it is saved with your ses-
sion.
In this initial state, only a single automa-
tion breakpoint appears at the beginning of
each automation playlist. If you move the
control without writing automation, this
breakpoint will move to the new value.
