The apparatus ( 1 ) comprises a guitar ( 3 ) having strings ( 42 ) operable by a user to generate electric signals, a control unit ( 2 ), storage means for a simulation backing track in any desired multi-media file format and audio/audio-visual equipment for playing a main track. The control unit ( 2 ) has software for receiving and analyzing the electrical signals from the guitar ( 41 ) and for synchronizing the backing track with the main track during playback. The software of the control unit ( 2 ) opens the backing track multi-media file and streams the file in mute mode in synchronisation with the main track. In response to the electrical signals from the guitar ( 41 ), the control unit generates an output from the multi-media file to the audio/audio-visual equipment. Alternatively, the apparatus opens and plays extracts from the multi-media file and generates an output from the multi-media files to the audio equipment ( 4 ) together with the background track.
