Bontempi B9 Electric Chord Organ (37 fullsize keys, 12 chord buttons), made in Italy

Link: weltenschule

Reed organ with pressure sensitive keys. 37 fullsize keys, 12 chord buttons.

This tablehooter is not an electronic keyboard, but basically a blower operated, keyboard- shaped plastic accordion with 12 single finger chord buttons and a volume slider that controls the air pressure. Great is that it is (at least theoretically) full polyphonic and has pressure sensitive keys for very expressive playability.
