An audio memory playback system has a playback device for playing back data stored in an audio memory, playback speed control for increasing or decreasing an addressing speed of an address generator, a display circuit for displaying the operational state of a key matrix, and an output circuit for providing the data stored in the audio memory. The audio memory playback system may playback a digital melody stored in the audio memory by recognizing an applied signal from the key matrix through the controller and control a playback speed of an audio signal according to a control signal of the controller, and carry out automatic selections.
