Abstract
A method and apparatus for playing a first sequence of sounds represented by data stored in memory synchronously with a second sequence of sounds represented by data stored in memory, at any point during the playing of the second sequence of sounds. A point in time is selected at which a specific sound in the first sequence of sounds must be played at the same time as the specific sound in the second sequence of sounds for the two sequences to be synchronous. The number of sounds in the second sequence which have been played before the current sound being played is counted and used to determine which sound in the first sequence is synchronous with the current sound in the second sequence. The data representing both sounds is then retrieved and used to generate, i.e. to 'play,' the identified sound in the first sequence simultaneously with the current sound of the second sequence.
