Dear Chony;

Remember that these are not refered to as arrangers but as "workstaions", and Top model arranger/worksations at that. By definition, workstations have samplers on board. The sampling reading capabilities are to allow the players to add more sounds that he/she wants that are not avaliable on the base keyboard. So this would ideal, you could add exactly what you want. You wouldn't have to pay for an expansion card with 100 sounds , only 5 of which are of actual interest. Also companies usually charge top dollar for these sounds, and they are only of medicore quality.

Chony, just to add arrangers players are always looking for the next great gadget/ software/hardware etc... that comes out, and subsequently they want it added to thier keyboards. These top model arrangers aren't cheap and are more pricey then alot of synths. So why shouldn't we ask for more options?

Further, as you said we are all not alike. I would like to see sampling compatibility, you wouldn't. So, in the end these companies are trying to please eveyone and capture as many sales as they can.

Regards;
