RTAS plug-ins have certain rules for how they must be used (these rules are the same as in Pro Tools).

To use RTAS plug-ins, you must:

* Run Digital Performer 4.5 or higher
* Use DAE as the Audio System (which requires TDM hardware).
* Place the RTAS plug-in on a voice track
* Assigning the voice of the track to Automatic
* Place it on an insert in the Mixing Board above (before) a TDM plug-in


You cannot use an RTAS plug-in:

* In Digital Performer 4.12 or earlier
* While MAS (MOTU Audio System) is the selected Audio System
* On an Aux or Master Fader Track
* On an insert beneath (after) a TDM plug-in


Also, make sure that your RTAS plug-ins are located in Library/Application Support/Digidesign/Plug-Ins. Lastly, check if the plug-in works in Pro Tools. If you do not see the plug-in while in Pro Tools, you will not see it while under DAE in Digital Performer
