Initially, Powered Plug-Ins will run on any VST/PC workstation. We have currently tested and approved for use the following software as of this writing: Steinberg Cubase, Nuendo and Emagic Logic Audio. More systems will be tested and approved in the coming months. Macintosh support for VST based host apps is planned for later this year along with support for MOTU's MAS format with their award winning Digital Performer.
