Wusik MXR is just a Mix and Mastering app (Windows) that allows you to import WAV files and setup track volumes and have it all mixed into a final master/release file.
This basic set of features would be the free version. And the paid version would cost $ 9.95 and allow access to a server that would let you render tracks with quality effects, but with generic names and limited set of options.
EG: you pick a track, select from a list of things to render the track with: compressor, Exciter, EQ for Bass, EQ for Mid, things like that.
In the server I will have top-quality plugins from undisclored companies that would take your track and render it for you.
I could add to this service analog off-board effects such as spring-reverb and plate-reverb (for a start).
Nothing is done in real-time, to keep things easier to handle.
I will come with more details soon.
