Surround Balancer
If the source is set to surround, the surround panner acts as a surround balance control.
Source channels are passed on to their respective output channels without any cross-
panning or mixing. The pan control is represented by a single puck, which affects the
multi-channel source signal as a whole. In other words, only the relative volume
balance of the source signal is changed.
The separation parameters are not available in this surround panner mode.
Inserting Surround Plug-ins
Logic Pro offers a number of surround effect plug-ins, and also includes surround
versions of the Sculpture and ES2 synthesizers. Your Audio Unit instruments and effects
may also work in surround.
Important: The project surround format determines the surround format of plug-ins.
To insert a surround effect plug-in:
1 Set the channel strip’s output to Surround.
2 Click on any Insert slot, and browse to the Mono → Surround (on mono channels),
Stereo → Surround (on stereo channels), or Surround version (on surround channels) of
the desired plug-in.
 As an example on a stereo format channel: Delay > Delay Designer > Stereo → 5.1
(ITU 775).
 If the project surround format is set to 7.1 (SDDS), the plug-in menu of a stereo
channel is displayed like this: Delay > Delay Designer > Stereo → 7.1 (SDDS).
∏
Tip: It is possible to release the mouse on the plug-in name, instead of navigating all
the way through the hierarchy to the channel format. This will automatically open the
plug-in using the default channel strip format.
