Abstract

An interactive music playback device includes a sequencer for processing audio information corresponding to a song or other selected piece of music. The audio information may be retrieved from a PCMCIA card or other suitable solid state data storage cartridge which is inserted in a slot in the playback device. The sequencer arranges the audio information in a playback sequence based on one or more user-specified playback parameters, such as tempo, key and playback duration. Voice and instrument synthesizers receive the playback sequence and generate therefrom respective vocal and instrumental portions of the selected piece of music. The playback device may operate in a verse-shuffle mode of operation, in which the sequencer arranges the playback sequence to include randomly-selected verses of the selected piece of music interspersed with a chorus of the selected piece of music. The parameters of the playback sequence may also be varied in accordance with measures of external conditions as received from one or more environmental sensors. The playback device may also include a network connection for use in downloading the audio information from a network to the playback device.
