Everything is setup correctly, and Automap works -
The mixer functions - track faders, solo/mute buttons, encoders when in "mixer" mode - all work fine.
While running Sonar, Automap is providing all the correct interactive prompts and editing functions.
Automap creates the wrapped version of the selected plugins, and the Automap version of the plugin exists in the same folder as the original plugin. Sonar detects these as new plugins during the VST scan.
However, the Automap-wrapped plugins DO NOT show up in the Plugin Manager. So, since the Automap version of the plugin isn't available to be inserted in a project, Automap has no plugins to work with.
Right now, it seems that the basic problem is Sonar's Plugin Manager is not recognizing the Automap-wrapped versions of the plugins, even though they are detected as new plugins when first created by Automap.
