A German-origin term which is generally used by collectors today. 1. An electrically-operated (usually) cabinet-style player containing a reproducing mechanism which uses reproducing piano rolls. The cabinet is equipped with felt-covered "fingers" and is pushed up to the keyboard of a piano. The fingers and corresponding pedal mechanisms then automatically play the keyboard and pedals of the piano. Vorsetzer = sitter-in-front-of, in German. Vorsetzers with reproducing mechanisrns were made by Hupfeld, Welte, and others. (This definition, vorsetzer with a reproducing mechanism, is the one generally used by collectors today.) 2. Any push-up piano player or device, often foot-pumped, which is placed in front of a piano or organ keyboard to play it. * Synonyms: piano player, push-up piano player.
