Abstract
Abstract A device for playing back a music or video source such as a digital audio tape recorder, Compact Disc, Laser Vision Disc, video tape recorder, television and FM broadcasting and analog records comprises means responsive to control information supplied from a music or video source device for controlling an externally controllable electrical or electronic musical instrument so as to perform the musical instrument automatically in synchronism with playback of the source device. An electrical or electronic musical instrument is performed automatically in synchronism with playback of a source so that a reproduction atmosphere which cannot be obtained by mere playback of the source can be created.
