Abstract
A music reproduction control apparatus includes: a first storing unit for storing main-digital data; a second storing unit for storing sub-digital data; a first reproducing unit for reproducing main-sound based on the stored main-digital data; a second reproducing unit for reproducing sub-sound based on the stored sub-digital data; a receiving unit for receiving an input signal; a first changing unit for changing a reproducing speed of the first reproducing unit based on the received input signal; a second changing unit for changing a reproducing speed of the second reproducing unit based on the received input signal; a correcting unit for correcting a key of the sub-sound in accordance with a change in the reproducing speed of the second reproducing unit; and a synchronizing unit for synchronizing a timing of changing the reproducing speed of the first reproducing unit with a timing of changing the reproducing speed of the second reproducing unit.
