Loopback and Playback instances share the same group functions. If you have instances
of Playback that you have assigned to a group, they will respond to any group functions
(except Record) as any Loopback instances assigned to the same group.
Only one group can be active at a time. For example, if two Loopback instances are in
Group A, and four Loopback instances are in Group B, activation of a transport function
in any Group A member will stop all Group B members, and vice versa. Instances that are
not in any group are not affected. Similarly, any Playback instance in Group A will also
respond, while Playback instances in Group B (or any other group) will stop.
All Loopback instances that belong to a group will switch between states for the following
transport functions when changed in any group member:
• Record
• Play or Stop
• Return to Start
• Dragging in the waveform display
• Fade Out (time and action)
• Count In
• Metronome
• Undo
• Reverse
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. 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 Loopback 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 Loopback 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 Loopback
instance to a group.
To remove a Loopback instance from all groups
µ
Choose the “–” item from the Group pop-up menu.
