Tracks and busses can be put into groups. Members of a group can share various settings — useful for managing tracks that are closely related to each other. Examples might include tracks that contain multiple-microphone recordings of a single source (an acoustic guitar, perhaps, or a drum-kit).
You can group tracks and busses in various ways. In the editor window, a track's controls might look like these:
The green tab to the left of the track header indicates that this track is in a group called Fred. You can drag these tabs to add adjacent tracks to a group.
There are several ways to create groups for tracks and bussess:
Context-click on a group tab and select Remove Group from the menu. Removing a group does not remove the members of a group.
You can also remove groups by selecting them in the Groups list and then pressing the minus (-) button at the bottom of the list.
Click the g button to display a menu with a list of the available groups. Select one of these groups to add the track or bus to that group. Select No Group to remove it.
Alternatively, you can also drag a group tab to add or remove tracks from the group.
Clicking on a group tab toggles the group between being active and inactive. An inactive group has no effect when editing its members. An active group will share its configured properties across its members. Tabs for disabled groups are coloured grey.
To edit the properties of a group, context-click on its tab and choose Edit Group…. This opens the track/bus group dialog, which is also used when creating new groups:
Click on the color selector button to change a group's colour. This affects the colour of the group's tab in the editor and mixer windows. The color does not affect the color of the group members unless you also enable the shared Color property.
Gain means that the track faders will be synced to always have the same value; Relative means that the gain changes are applied relative to each member's current value. If, for example, there are two tracks in a group with relative gain sharing, and their faders are set to -3 dB and -1 dB, a change of the first track to a gain of -6 dB will result in the second track having a gain of -4 dB (the difference of the gains remains the same).
Muting, Soloing, record enable, active state, colour and monitoring are all straightforward. They simply mean that all member tracks or busses will share the same settings in these respects.
Selection means that if a region is selected or deselected on one member track, corresponding regions on other member tracks will be similarly selected. Since region editing operations are applied to all currently selected regions, this is the way to make edits apply across all tracks in the group.
Context-clicking on the group tab offers a further menu of group-related actions.
