Abstract
A first musical tone to be generated by a musical tone generating channel and a second musical tone which is the same as the first tone and which already has been generated by another musical tone generating channel are both generated in a superposed manner. When the first tone is generated, the volume of either the first tone or the second tone is superimposed on the generated volume of the other musical tone. Also, the volume attributed to the first musical tone due to decay is reproduced by changing the volume of the second musical tone.
