Abstract
A music practice supporting appliance has an input unit that inputs a musical sound of a musical instrument and/or vocal music, converts the musical sound into an electric signal, and outputs the electric signal as an input signal. An amplifying unit amplifies the input signal outputted from the input unit. A processing unit processes the amplified input signal to obtain input signal data. A first memory unit stores the input signal data. A second memory unit stores input signal data stored in the first memory unit when the input signal data stored in the first memory unit exceeds a preselected storage capacity of the first memory unit. A control unit controls the first memory unit and the second memory unit so that while the first memory unit is receiving for storage thereinto new input signal data which causes the first memory unit to exceed the preselected storage capacity, portions of input signal data previously stored in the first memory unit are deleted from the first memory unit and are stored in the second memory unit, and the new input signal data is stored in the first memory unit. A display unit displays the input signal data stored in the first and second memory units.
