9 Evenings: Theatre and Engineering fonds

File: Proportional Control System

For 9 Evenings, Fred Waldhauer created the Proportional Control System (P.C.S.) used by David Tudor in Bandoneon! (a combine). This interface was comprised of a plotting board, 16 receivers and an electronic pen to allow numerous components in the Armory to be remotely controlled. Notably, Tudor used the device to spatialize the sound tracks and adjust the volume from one speaker to another.
