ABSTRACT:
In an electronic musical instrument, a tone property setting device is provided in association with a musical tone forming circuit. The device delivers analog signals designating properties of the musical tone signals to be produced, which analog signals are converted into time division multiplexed digital signals, then processed through memories, converted back into analog signals, and are applied to the musical tone forming circuit, thereby to determine the tone properties. Digital processing utilizing the memory facilitates a variety of control.
