this would be a style creator dream!

it looks very flexible and i hope one day, soon enough, we'll see it in practice.
if you add a 12/13" touch screen, or even bigger, that would be perfect.
i am not convinced about the audio-arranger thing, i believe that can not be done without high performance disk streaming, high proccessing power, and with huge amount of work - recording, editing, etc.
but an easy mix of different midi loops/phrases, in the manner described in one of the videos, like i said, would be a dream! i'd love that!
