Working with the Surround Master

When you set the output of a channel strip to surround, a surround master channel strip is automatically created in the Mixer. The surround master channel strip processes the signals routed to the outputs, as configured in the Surround preferences (taking the project’s surround format into account, of course).

Figure. Master channel strip.

You can insert surround effect plug-ins into the master channel strip.

Important: As soon as the master channel strip appears, the Insert slots of the individual output channels are hidden, and any existing effects in the Insert slots (of output channel strips) are no longer processed. Logic Pro remembers the Insert configuration, so when you remove all surround outputs, the original output channel configuration is restored.
