Does Duende support Digidesign's RTAS format?
Yes, Duende does support the Digidesign RTAS plug-in format for all variants of Protools.
Duende Native v4 is the first software to feature the whole plug-in suite available as un-wrapped RTAS versions. This provides a multitude of advantages over the wrapped RTAS plug-ins of Duende v3 software and earlier. See for more information about Duende Native V4 RTAS plug-ins.
Duende software v3.6.6 and lower uses the VST-RTAS wrapper technology from FXpansion, and incorporates this into the Duende installation procedure to make setup as easy as possible. This provides fully compatible RTAS versions of Duende plug-ins.
Multi-mono plug-ins are not supported
Custom mapping to different control surface like Icon/D-Command/Control24 is not supported
