Celemony provides an extension of the Audio Units plug-in standard called Audio Random Access (ARA). The ARA extension enables a host application and compatible plug-in to share song structure information (for example, regions and their associated audio files) and analysis results (including transients and pitch information). Logic Pro now supports ARA 2 compatible plug-ins, such as Melodyne.
Using a compatible plug-in in ARA mode provides several benefits to speed your workflow: First, there is no need to capture audio before working in the plug-in. Second, no edits to regions are lost when you move or copy the audio region to another track, as long as the plug-in is inserted in ARA mode in the first audio effects slot. In addition, your edits to the audio material are preserved when you copy the project.
When you insert a plug-in in ARA mode on an audio track, Flex is disabled. Also, the Compare button is not available in the plug-in window. Before you begin working, you start playback momentarily to transfer song information and all relevant audio analysis results to the plug-in. You can start editing in the plug-in immediately after the information is transferred. If you move, copy, or edit regions on the track, the updated information is transferred the next time you start playback.
In the first Audio FX slot on an audio channel strip, choose Audio Units > Celemony > <plug-in name> (ARA).
ARA mode is available only in the first Audio FX slot on an audio track.
After the plug-in window opens, start playback.
Edit the audio material in the plug-in window.
You can use an ARA 2 compatible plug-in as part of selection-based processing. For more information about ARA, refer to the manufacturer’s documentation.
