**Automation** is a way of dynamically changing audio processing parameters over time.
|
||||
_Automation_ is a way of dynamically changing audio processing parameters over
|
||||
time.
|
||||
|
||||
Up to now, we have used fixed values for various parameters of our Tracks (for example, a Track Fader set to -3.0 dB; or a Mono Panner set to 100% Left; etc.) These fixed values would apply for the entire Track throughout the whole Session.

||||
Up to now, we have used fixed values for various parameters of our tracks, for
|
||||
example, a track fader set to -3.0dB; or a mono panner set to 100% left. These
|
||||
fixed values would apply for the entire track throughout the whole session.
|
||||
|
||||
But what if you would like these values to change over time in a pre-determined way? For example, you may want to have the Gain of a Track to gradually decrease over twenty seconds. Or you may want to make a sound move from Left to Right over two seconds.

But what if you would like these values to change over time in a

pre-determined way? For example, you may want to have the gain of a track to
|
||||
gradually decrease over twenty seconds. Or you may want to make a sound move
|

from left to right over two seconds.
|
||||
|
||||
This is accomplished with **Automation**. The Fader, Panning, and any of the
|
||||
parameters of the Plugins used in that Track can be automated. An
|
||||
automated parameter is displayed underneath the parent track in its own
|
||||
**Automation Track**. Automation data is visually represented as an
|
||||
**Automation Line**, made up of a number of **Automation Points**.

In the image above, the Automation Track called "*Fader*" is associated

to the parent Track called "*Audio 1*". The Automation Line controls

Fader (volume) changes over time.

|

|
||||
## Creating a Fader Automation Line
|
||||
|
||||
Let's create a simple Fader Automation. Click the "*A*" button of a chosen track. A menu will appear, where you can select the parameter you would like to Automate. Choose "*Fader*".

Now you can create Automation Points by clicking anywhere in the Automation Track. An Automation Line joins the Automation Points you add. The yellow number (-15.3 decibels in the image below) indicates the Gain level for the selected Automation Point.

automation point.

### Automation States
|
||||
|
||||
The Automation Curve will not play, however, until you set the Automation State to "*Play*".
|

The automation curve will not play, however, until you set the automation state
|
||||
to _Play_.
|
||||
|
||||
|
||||
|
||||
**Manual**: When set to "*Manual*", the Track will ignore any Automation data. It will just play with whatever volume is the Fader is set to. In this mode, you are able to move the Track Fader by hand to set a new fixed level. That's the default behavior of a Track when it's first created.
|
||||
**Manual**
|
||||
: When set to _Manual_, the track will ignore any automation data. It will just
|
||||
play with whatever volume is the fader is set to. In this mode, you are able to
|
||||
move the track fader by hand to set a new fixed level. That's the default
|
||||
behavior of a track when it's first created.
|
||||
|
||||
**Play**: When set to "*Play*", the Track will automatically change the Gain levels following the Automation Curve drawn in the Automation Track. You will no longer be able to move the Track Fader by hand. During playback, you will see the Track Fader moving up and down according to the curve.
|
||||
**Play**
|
||||
: When set to _Play_, the track will automatically change the gain levels
|
||||
following the automation curve drawn in the automation lane. You will no longer
|
||||
be able to move the track fader by hand. During playback, you will see the track
|
||||
fader moving up and down according to the curve.
|
||||
|
||||
**Write** mode will continuously record user changes to the Automated
|
||||
parameter as the Transport plays, creating an Automation Line. For
|
||||
instance, you may start playback and then make real-time changes in gain
|
||||
using the Fader of your Track. All the changes you
|
||||
make will be written (recorded) as an Automation Line, which then you
|
||||
can play back later by switching the Automation Mode back to Play

|
||||
|
||||
**Touch** mode is similar to Write mode. Unlike Write mode though, Touch
|
||||
mode won't record over existing Automation data unless the parameter is
|
||||
being changed.

If these concepts are new to you, focus now on just the first two modes (*Manual* and *Play*), and practice creating automation by drawing Automation Curves by hand.

## Creating a Plugin for Automation
|
||||
|
||||
You may add Automation to any Plugin which has already been added to a
|
||||
Track. In the example below, we have a "**AM pitchshifter**" Plugin added to a track.

|
||||
|
||||
|
||||
|
||||
In order to select a Plugin parameter for Automation, click the
|
||||
button on the Track marked "*a*". The menu will appear. Under "*Processor Automation*" you will find a listing of the Plugins you have added for that Track.

|
||||
|
||||
|
||||
|
||||
Within each listed Plugin, you may choose which parameter you want to
|
||||
Automate from a list. In the example, we chose the parameter "*Pitch
|
||||
shift*" of the Plugin "*AM pitchshifter*". An Automation Track for that
|
||||
parameter appears. Note that as you open several Automation Tracks, they
|
||||
will appear one after the other below the main parent Track.

|
||||
as you open several automation lanes, they will appear one after the other
|
||||
below the main parent track.

||||
|
||||
Draw an automation curve for that parameter. Don't forget to set the Automation State to "*Play*".

You can hide an Automation Track by clicking on the "X" at the upper
|

left corner of the Automation Track. Note that a hidden Automation Track
|

## Adding Better Visual Resolution to Automation
|
||||
|
||||
You can achieve a greater amount of vertical precision by increasing the
|
||||
height of the Automation Track. Move your cursor near the lower edge of the Automation Track. The pointer turns into a vertical double arrow. Drag it down to increase the height of the Automation Track. Notice that the parent Track and the Automation Track heights are independent, so while working in your Automation Curves you might set them up like this:

- To remove an Automation Point, hold down the "*Shift*" key while Right-Clicking on it (works in Grab, Draw, and Edit modes).
|
||||
- Edit Mode only: any segment of the Automation Line between Automation Points may be dragged vertically, affecting both end points at once, without affecting their horizontal position. Simply click somewhere on the line between two points, and drag up and down.
|
||||
- How to delete multiple Automation Points at once (Grab Mode and Edit Mode only): select multiple Automation Points by dragging a box starting on the track background around the points. Then the selected points may be deleted by hitting "*Delete*" (*not* "*Backspace*"). If you are on a Mac and do not have a true "*Delete*" key, try "*Function*" + "*Backspace*").

The screenshot above shows a simple gradual fade starting from the first Region in the track, and ending at the last Region. It's very straightforward to do this with Fader Automation, but but it would be much harder to do it using region-specific automation.
