Abstract of the Disclosure A microprocessor controlled electronic capture combination action system for use in an electronic organ for selecting a predetermined combination of stops to define the organ voicing. The system includes a plurality of stop tabs for setting and resetting the stops, a plurality of pistons for setting a desired combination of stops to n predetermined condition, a random access memory for storing data associated with n selected combination of stops, a read only memory containing a permanently stored operating program incorporating a plurality of operating instructions, an indicator light associated with tach of the stop tabsand a microprocessor responsive to the operating instructions. The stop tab andpistons are continually and sequentially scanned to detect contact closures. Actuated stop tabs cause the associated stops to be selected and the indicator lights illuminated. Information corresponding to a selected combination of stops for a selected one of the pistons is stored in the random access memory and may be recalled at will by closing the appropeiate piston. The recalled data is used to select the combination of stop and illuminate the associated indicator lights.
