CHP. 7 USING AUTOMATION
161
Adjusting effect automation settings
You can adjust automated effect parameters by editing the envelopes in the timeline or by recording
automation with the controls in the Audio Plug-In Window.
If you’ve enabled the Bypass parameter for a plug-in, you can click the Bypass button in the plug-in's banner
to toggle the Bypass envelope at the cursor position.
Note:
When you automate an effect’s frequency parameter,
such as the frequency parameters in the track EQ effect, you
may notice that the frequency changes are more apparent
when moving through the lower frequencies. This is because
frequency scales in track EQ and other plug-ins use a
logarithmic scale, but effect automation uses linear
interpolation. To make the automated frequency changes
sound more natural, change the fade curve types to change
the interpolation rates between envelope points. For high-to-
low frequency sweeps, use a fast fade curve; for low-to-high
frequency sweeps, use a slow curve. For more information,
see Changing envelope fade curves on page 164.
Composite level automation (video only)
You can use the composite level automation envelopes to adjust the opacity of a track over time.

Drag the slider to control the transparency or blending of each track. Left
is 100% transparent and right is 100% opaque. You can also double-click
the percent to enter a specific value.
• When the track automation mode is set to Off, the slider adjusts the send
level of the entire track. In this mode, the automation control acts as a second trim control.
• When the track has a composite level envelope and the track automation mode is set to Read, the slider
will follow the envelope during playback but cannot be adjusted.
• When the track has a composite level envelope and the track automation mode is set to Touch or Latch,
the slider edits the envelope setting at the cursor position. If the track does not have an envelope, one
will be created when you adjust the slider.
