Note: With the release of Logic Pro v10.7, Logic now supports a fully-integrated Dolby Atmos workflow. For more information on the new features and how to use the new Dolby Atmos tools within Logic, check out the new Quick Start video and the Logic Pro section of the Knowledge Base.

In order to record a Dolby Atmos Master, the Dolby Atmos Renderer needs to synchronize to Logic Pro via LTC. This is done be sending LTC audio over channel 129 or 130 of the Dolby Audio Bridge using the Dolby LTC Generator plug-in.

The Dolby LTC Generator plug-in is included with the Dolby Atmos Renderer 3.7 installer.

To use the Dolby LTC Generator plug-in, create a new Software Instrument track in Logic:

-Navigate to Track > New Software Instrument Track or enter Command+Option+S
-Rename the track LTC 129
-Insert the Dolby LTC Generator plug-in in the Instrument slot

-The Dolby LTC Generator plug-in is located at AU Generators > Dolby Laboratories > Dolby LTC Generator > Mono
 

-Set the output of the track to Mono Output 129
-Open the plug-in window

-Set the Frame rate to 24 fps (or to match the Renderer)

Note: When using the Dolby Atmos Music Panner v1.2 the start time must be set to 00:00:00:00.

 

Navigate to the Renderer, enable sync, and push play in Logic to verify the Renderer is chasing.
