Using the Playback Group Functions
If you have multiple instances of the Playback plug-in in a concert, you can use groups
to control which instances play together and which instances operate independently.
Any Playback instance can either be assigned to one of 26 Groups, named A-Z, or not be
a member of any group. The linked operation of multiple instances can be used for
creative playback purposes, such as alternative versions of a song verse or chorus.
Only one group can be active at a time. For example, if two Playback instances are in
Group A, and four Playback instances are in Group B, activation of a transport function in
any Group A member will stop playback of all Group B members, and vice versa. Instances
that are not in any group are not affected.
All Playback instances that belong to a group will switch between states for the following
transport functions when changed in any group member:
• Return to Start
• Play or Stop
• Dragging in the waveform display
• Cycle
• Fade Out (time and action)
• Go to Previous (or Next) Marker
Important: Editing a parameter in one member of a group does not automatically update
the parameter value in other group members. To change the parameter value in all group
members, hold down Shift while you edit the parameter in any group member. This
applies to the Meter, Fade Time, Pitch, Sync, Snap To, and Play From parameters. You
need to set Sync to the same mode for all group members or you will hear playback drift
between grouped instances.
To assign a Playback instance to a group
µ
Open the Group pop-up menu at the lower right of the interface and choose a letter.
Note: When a Playback instance is added to an existing group, some button states may
be different from other group members. If you want all group members to behave
identically when a transport button is used in any group member, make sure that the
states of all buttons match those of other group members before you add a Playback
instance to a group.
To remove a Playback instance from all groups
µ
Choose the “–” item from the Group pop-up menu.
