JAMES, thanks for really nice explanation.
That I want to tell to you guy but it is hard to explain things so close.

MS is VST host for all matters. Interesting is that is also prepared for live playing. That means that you can play with any kind of sounds or styles or things that you want on MS- it is like playing tool.

And Interface that is look like on keyboards from box is ready any time. So When you play on stage you are playing like out from BOX.
