An existing Mix group can be assigned to a VCA Master, or a new Mix group can be assigned to a VCA Master while it is being created. Only one group can be assigned to a VCA Master at a time. A VCA Master cannot control a group that includes itself.
It is possible for a single slave track to be a member of more than one VCA-controlled group. In this case, the contribution of all VCA Master Volume faders is summed on the slave track. Mute, Solo, Record Enable, and TrackInput follow the same rules for enabling or disabling slave tracks.
