That's it in a nutshell, squeak... it isn't an arranger, it isn't a WS, it's a hybrid.

And, in today's environment of the majority of sequencing, recording and editing being done on computers, with a simple transfer to the keyboard once the work is done (pretty similar to the S900, in a way, with having to use software to make up for limited on-board editing), much of the 'missing' features are kind of moot.

Personally, I haven't used an on-board sequencer for decades! Style creation is also primarily handled by software these days, although Roland do have what I think is the best on-board out there, but I think most people work on styles with things like EMC, etc., nowadays.

Don't forget it's price point... At well under a grand, it seems like a bargain to get Roland styles and sounds, even if you DO have to give up some editing flexibility...
