Ian, I really would class what most would call motl Roland arrangers currently on offer at the lower end of motl, or upper end of the botl..

The Bk series and the GW 8 series are (were in the case of the GW's) STILL relying way too much on the Sound Canvas sounds that first appeared in the nineties!! Albeit with minor (VERY minor) tweaks...

And the OS's are abysmal!! Just my view of course, others may think differently.

Yamaha and Korg DESERVE their market places now, as they both continue to innovate and provide more a more up to date sounds, features and OS's...

Whether the updates are free or require a new hardware purchase is irrelevant in my view, the fact that they continue to do so is the important thing, and the thing that will keep people coming back time after time.
