Use the Loopback group functions

If you have multiple instances of the Loopback plug-in in a concert, you can use groups to control which instances record and play together and which instances operate independently. Any Loopback 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 purposes, such as alternative versions of a song verse or chorus.

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.

Assign a Loopback instance to a group

  • Choose a letter from the Group pop-up menu at the lower right of the window.

    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.

Remove a Loopback instance from all groups

  • Choose the “–” item from the Group pop-up menu.
