1. In an electronic musical instrument having means for providing input signals carrying note selection and note sequence function selection information, means for generating tones, and means for controlling the tone generating means in accordance with note and note sequence function selection information supplied thereto, an improved circuit for supplying information to the control means, comprising: means for multiplexing together, on a time division basis, the note and note sequence function selection input signals: an encoding circuit responsive to the multiplexed signals for providing binary coded signals respectively representative of the note selection and function selection information carried thereby; storing means including a note memory for storing said note selection codes and a function memory for storing said function selection codes; and demultiplexing means including means responsive to the code signals and said multiplexing means for respectively enabling the note memory and the function memory during the time divisions that said note selection signals and function selection signals are being applied to the encoding logic input means whereby the note selection codes and the function selection codes representative of the information carried by the multiplexed signals are respectively stored in said note and function memories.
