Data encoder for an electronic musical instrument

A data encoder for use with a time multiplexed electronic organ or the like comprises a multiple stage shift register, means for simultaneously loading a predetermined pattern of logic bits in the shift register in response to a key down representative data pulse and means for coupling the output of the shift register to one of the data channels of the organ. In a first mode, the data encoder is operable as a fill-note generator wherein the shift register is loaded in response to an upper manual key down representative data pulse and lower manual key down representative data pulses are coupled to the upper manual data channel of the organ according to the output of the shift register. In a second mode, the data encoder is operable as a chimes generator wherein the shift register is loaded in response to an upper manual key down representative data pulse and the output of the shift register is coupled to the upper manual data channel of the organ. In a final mode, the data encoder is operable as a chord function generator wherein the shift register is loaded in response to a lower manual key down representative data pulse and the output of the shift register is coupled to the lower manual data channel of the organ.
