Click the Configuration button on the extended plug-in window header to switch to a pane where you can group the individual instances of the plug-in.
In Logic Pro for Mac, when a plug-in in multi-mono mode is first inserted into a surround channel, it is automatically preconfigured to match the project surround format and to make the best use of the plug-in’s capabilities. For example, a plug-in with mono and stereo capabilities is inserted into a 5.1 bus. It is preconfigured as two stereo pairs, with the addition of a mono center and mono LFE channel. The necessary links and buttons are created automatically. With this configuration, you can adjust the effect of the LFE channel separately from the other channels.
You can change the group assignment in the Configuration pane, which shows a surround field with speaker icons, indicating the project surround format. Each speaker channel is shown with its corresponding channel letter (L, C, R, and so on), a Link button, and an Effect On/Off button .
In Logic Pro, click the Configuration button in the extended plug-in header to switch the view to the Configuration pane.
Click the Link pop-up menu of a channel and choose any of the five groups A, B, C, D, or E.
Click the Link pop-up menu of other channels and choose the same group if you want to link those channels, or choose a different letter to create a different group.
When you link channels, keep the following in mind:
If you link two channels as a stereo pair, the left channel is always assigned as the master.
If one or more channels are added to an existing group, the new members adopt the values of the group.
If you assign several channels to an unused group, the setting of the (front) left channel is used for all group members.
Any group that is used will be listed as a channel button in the extended plug-in header. The label on the button indicates which channels are linked in that group. If all channels are linked to the same group, the header displays a single channel button labeled Surround.
In Logic Pro, click the Configuration button in the plug-in header to switch the view to the Configuration pane.
Click the Link pop-up menu on the channel and choose the hyphen (“-”).
A channel that is not linked to a group will have its own channel button on the extended plug-in header. The label shows the speaker channel letter (for example, LFE or Rts).
