ARA is not implemented in Pro Tools. Maybe Avid should be encouraged to read the last paragraph.
From the Celemony site:
Melodyne editor, assistant and essential from Version 1.3 upwards can be operated with ARA in Presonus Studio One 2 and from Version 2.1.1 upwards also in Cakewalk Sonar X3 and Tracktion 5. Other manufacturers and products will follow.
If you would like to support ARA as a developer and are interested in the ARA SDK, please contact
