Mixer components in surround and spatial audio projects in Logic Pro for Mac
When you create a surround or spatial audio project in Logic Pro for Mac, the Mixer changes as follows:
Pan controls: In a stereo project, the tracks have the standard stereo Pan knob because the stereo output signal has only two channels: left and right. In a surround project, the tracks have the Surround Panner, which lets you position the signal on the multichannel output. A spatial audio project uses the Surround Panner for its bed tracks along with the 3D Object Panner for its object tracks.
Output channel strip: The output channel strip, which is the main output of any stereo project, is hidden in surround and spatial audio projects.
Master channel strip vs. surround master channel strip: The master channel strip in a stereo project has no controls other than the volume fader, which functions as a VCA master fader for all existent output channel strips, including the Stereo Output channel strip. The master channel strip changes to the surround master channel strip when you switch to a surround or spatial audio project. In addition to level meters, it has Effect slots to process the multichannel outputs and a Bounce button to bounce the surround output or the signal determined by the monitoring format of a spatial audio mix.
Dolby Atmos plug-in: A spatial audio project has the Dolby Atmos plug-in inserted on its surround master channel strip.
