The MS is more of a real work station that just keeps improving in time....& also includes a way to play styles like an arranger also.....the fact that it is an ongoing process with it's OA operating system is exciting because who knows in 2 or 3 years what improvements will be able to be implemented & beyond. When you buy a unit like the Fantom, Motif,Triton, etc your stuck with what ever it comes with & no way to also play arranger styles....& the only improvements are minimal Os updates......so you are forced to BUY another unit when they are released each time versus the improvement you can make thru the years on the MS which you would already have. I would consider an MS 61 key model down the road also which is coming soon.
