PURPOSE:To enable reproduction and performance of the outputs of sound reinforcing means with proper sound volume balance by connecting the outputs of other external sound source supply means to a mixing circuit in addition to the sound source circuit of the device so that they can be mixed. CONSTITUTION:The electric signal of a key of a keyboard part 10 operated by a player is supplied to the mixing circuit 14 through the sound source circuit 11. In this case, when the performance sound from a CD player 15, etc., is desired to mix at the same time, a desired CD disk is loaded and respective decks are placed in a playback state. When a 'KARAOKE' (orchestration without lyrics) is desired to mix, a hand microphone 17 is connected. Therefore, three mode sounds which are, for example, the live performance of the player, the playback performance of the CD player 15, and a singing voice can be mixed at the same time and the sounds can be sounded from a speaker as the sound reinforcing means 19 at the same time with proper sound volume through a master sound volume control part 20 or expression pedal 21. |
