A sound field effect adding apparatus is provided to add such effects as reverberation to the musical tone signal of an electronic organ and the like, and to produce a sound field effect. It is possible to create a satisfactory reproduced sound field to which a sound field effect has been added by means of a low frequency component without having to provide a dedicated unit or dedicated speaker system that can reproduce low frequencies. The apparatus has an input terminal with which a musical tone that includes a low frequency is input, and a means in which a sound field added musical tone signal is generated that produces a sound field effect that is based on an input musical tone signal. The apparatus has a first output terminal with which this sound field added musical tone signal is output to a speaker system used for sound field reproduction, and a generation means in which a low frequency component of the sound field added musical tone signal that contributes to the production of the sound field effect that is related to the low frequency is generated, which is different from the sound field added musical tone signal that is output by the first output terminal. The apparatus also includes a second output terminal with which this low frequency component is output to an external device.
