Abstract
An arrangement for providing an automatic musical performance in which a digital signal indicating a root tone is obtained by depression of a key, and is added in sequential order with digital signals obtained from a memory circuit. The latter is driven by output pulses of a rhythm pulse generator. Binary coded signals from the outputs of the adder, open and close plural gate circuits interposed in plural tone source signal passing circuits. One decoder is provided at the plural output terminals of the adder, and plural output terminals of that decoder are connected to control terminals of respective gate circuits. The decoder converts the binary code signals into address signals. An additional decoder may be provided at the output of the adder for converting the output binary code signals to binary-coded duodecimal codes.
