Neither of these are NEXT generation arrangers. Firstly, one of them isn't even released yet, but let's not go into that, right now... I believe both of these to be bleeding edge THIS generation arrangers. Let's face it... unless they turn magically into huge commercial successes, both of these will merely be footnotes in arranger history.

The Audya, I still see with substantial problems to solve before it matches the hype. Live audio loops will almost certainly mean a much smaller choice of chord/inversion/root types, which we all enjoy at the moment. It will sound GREAT doing the things it can do, and it won't be able to do anything else. Forget editing styles, forget creating styles, forget the choice of ANY chord you can think of...

The MS, OTOH, has been out for quite a while. Maybe it's complicated architecture is what's holding it back, maybe the style library, maybe just it's obscurity, but one thing is for sure... A LOT more people got to get on this one's bandwagon before it's any harbinger of the NEXT generation.

Many a keyboard of the past has shown us that technical innovation and forward looking concepts have not necessarily guaranteed either success, OR that the market would head in their direction. The market tends to take the path of least resistance, and both of these products make the user make some quite considerable change to the way they actually make music.

Probably not what we are actually looking for.
