Disabling Mixer Groups
You can temporarily disable all group parameter links—applying a group clutch—to
change the volume of an individual channel strip, for example.
To temporarily disable all groups
Do one of the following:
µ
Choose Options > Group Clutch (or use the Toggle Group Clutch key command, default
assignment: Command-G).
µ
Deselect the “Groups active” checkbox in the Group Settings window.
While Group Clutch is activated, all Group slots change color—from yellow (normal) to
a light gray (all groups temporarily disabled).
Automating Mixer Groups
When you are automating your mix functions (volume, pan, mute, and so on), any channel
strip group member can act as the mix automation master for that group. When you use
that group member to write an automation parameter value, it is also written for the
other group members, depending on their automation mode.
The data is written individually for each channel strip. As a result, you can disable the
group later without affecting the automation of any group member—and you can edit
or change channel strips individually when they are removed from the group.
For details about automation, see Working with Automation .
Muting Channel Strips
Use the channel strip mute function to remove individual channel strips from the main
signal flow (turning off the channel strip) or to remove any unwanted region sections.
The channel strip mute function is also useful when you are setting channel strip levels
and setting the Pan, or Balance.
