A musical sound control apparatus (1) includes a slider (17a), a CPU (11) and a recording ring buffer (13a). The slider (17a) enables scratching in both directions. The CPU (11) plays back musical sound data being sequentially supplied. The recording ring buffer (13a) rapidly stores, in response to emit a sound of the musical sound data being supplied, the musical sound data. The CPU (11), in a case of a scratch operation being performed on the slider (17a), controls so as to read out and playback the musical sound data stored in the recording ring buffer (13a) in place of the musical sound data being supplied, based on a direction and operation speed of the scratch operation.
