"PRO"

On the topic of what a "PRO" keyboard is. To me, what "PRO" means is that the keyboard is built to be reliable in the face of rough treatment and with cost versus sound-quality decisions made in favor of the latter. Often novel features are accepted first by consumers and only later by PROs, as Scott can give testimony to. (E.g., autoexposure in 35mm cameras, color viewfinders in video cameras, arranger features in keyboards). In short, when a manufacturer calls a keyboard "PRO", they should mean "you can bet your gig on this".
