Abstract

A plurality of pre-recorded, generated or other sound tracks (e.g. voice, karaoke) are selectable and de-selectable by a user for synchronously mixing with a main song track and all other sound tracks that are playing. The sound tracks are matched and synchronized to the song track. A visual display depicts icons which represent the sound tracks, and indicate which sound tracks are selected and de-selected. The user creates an individual musical performance by interactively selecting and de-selecting one or more sound tracks using a joystick or keyboard on a real-time basis with instantaneous visual and audible feedback. Depending on the musical content of each sound track, various operational modes ensure that whenever a track is selected, the result is always immediate, musically synchronized and aesthetically pleasing.
