78 Chapter 7 Mixer, Instruments, and Effects
7 Return to the beginning of the newly-recorded automation track, using any of the
navigation methods you learned earlier, and press Play. Note that the fader on the Track
Mixer (and the Arrange window fader—assuming the same track is still selected) is
now replaying your recorded automation movements. This automatic playback of
changes to the Track Mixer’s channel parameters is often referred to as flying fader
automation.
The same automation method can be used for controlling the volume of additional
channels, automating Pan knob positions, EQ, and plug-in parameter automation.
Editing Automation Data
You’ll probably want to edit your recorded automation data at some stage or another,
or perhaps to create some automation more precisely. The following paragraphs offer a
brief overview of automation editing techniques. More information can be found in the
Onscreen Help system or Logic reference.
Before we start, we’d like to cover a couple of concepts. Namely, those of “nodes” and
“lines” in the Automation data.
• Nodes are dots on an automation track that represent a particular value and time
position for the defined automation type.
• Lines connect the dots, and represent a linear (straight) or curved transition of
automation values over time. A ramp up in volume between two nodes, for example.
Inserting Nodes
A short click anywhere in the automation track will insert a node at that position, and
value. A short click on, or just outside, a line will insert a node on the line.
Deleting Nodes
To delete a node, simply click on it quickly (a short click). The position of the node will
determine what happens to the automation data. Try these and use the Undo or Revert
to Saved functions between each.
• Click on the first node, and it will be deleted. This will, in turn, make the second node
the first node. A click on this node will delete it and make the (original) third node,
the first node and so on.
• The same also applies to the last node, but works backwards from the last, second to
last, third to last nodes and so on.
• Clicking on a node which falls between two other nodes will delete it, and the nodes
which surrounded it will be joined directly by a recalculated line.
Moving Nodes
It is possible to select one, or multiple nodes (and therefore the lines which connect
them). You can move adjacent nodes—nodes that are beside each other—or you can
move non-contiguous nodes—nodes that are separated by other nodes. Select non-
contiguous nodes with the Shift key depressed.
