Kronos Editor and Plug-In EditorKronos Version 1.5 adds support for the Kronos Editor and Plug-In Editor, which allows the editing and organizing sounds from a Mac OS X or Windows computer. Plug-in operation allows you to save settings as part of your project with any VST-compatible Windows software, or any VST- or AU-compatible software on Mac OS X.
It will probably do what it says on the can as Mr. Lord points out. Two versions of the Editor - stand-alone and VST. That's exactly what it says on the Korg web site as copied here....
