 Automation Mode checkbox: Changing the automation mode of an individual track in
a group will change the automation mode for all group members.
 Channel Strip Color: Changing the color of one group member channel will assign
this color to all group member channels. Using color makes it easier to identify the
string or brass sections, for example.
 Volume checkbox: Changing the volume fader of one group member channel will
change the volume of all member channels—while maintaining the level
relationships between them. Use a volume fader with a high initial setting, if
possible, as this will allow you a greater range of movement, and therefore, control.
 Mute checkbox: The mute status of all member channels is synchronized, with all
group members being muted or unmuted if one group channel is muted/unmuted.
 Pan checkbox: The panorama setting of all member channels is linked. As per
volume, their initial relationships are maintained.
 Send 1 to 8 checkboxes: You can link the Send knobs individually for Send slots 1 to 8.
Different initial levels will be maintained.
A Note on Group Automation
Any group member can act as a master for mix automation of an automated
parameter, such as volume. When an automation parameter value is written, the
corresponding value of all other group members is also written, depending on their
automation mode (Touch or Latch, for example). The data is written individually for
each channel. As a result, you can disable the group later, without affecting the
automation of any group member—and can obviously edit or change channels
individually, once removed from the group.
Disabling Groups Temporarily (Group Clutch)
It is possible to temporarily disable all group parameter links—in order to change the
volume of an individual channel, for example.
To temporarily disable all groups:
m Choose Options > Group Clutch (or use the Toggle Group Clutch key command, default
assignment: Command-G).
As long as the group clutch is active, all group displays will change color—from yellow
(normal) to a light gray (clutch active, all groups temporarily disabled).
