I suspect Yamaha and Korg took up the slack left by Roland's lessening product line, so both companies are selling arrangers at a good pace.

Thing is, most people who own an arranger, use barely half of what it can do...and that includes some pros.

So adding new features, irregardless of brand, is always going to be carefully thought out by the designers...remember, PROFIT is the ultimate goal for all these companies.
