Arranger keyboards are more lightweight, and usually more inexpensive than workstation keyboards. (Workstations tend to have more complex hardware and software, making them heavier and pricier.) Arranger keyboards are built for ultimate portability and rugged durability, even for full-sized 88 key models. And while workstation keyboards are made for studios and touring ensembles, arrangers are ideal for solo performers, entertainers, and producers. They also present a modestly priced way for keyboard players to experiment with a wide spectrum of sounds and rhythms.
