Abstract
An operating member control device of an electronic musical instrument is constructed by a main unit and a plurality of subunits, each of which has a operating member for setting a musical tone element and a drive mechanism for moving the operating member. The main unit transmits in serial form a set of control data signals, which are preset in advance, designating desired target positions of the operating members respectively. The subunits further include serial to parallel converters, each of which receives the control data signals and serial-to-parallel converts the corresponding one of the control data signals. The operating members are moved from the current positions to the desired positions designated by the parallel converted control data signals respectively. By the construction as above, this operating member control device need a single line only with respect to the connection of the main unit and the subunits basically, thereby enabling simple wiring.
