PURPOSE:To prevent a fact that the sounding quantity increases in vain and the sound becomes low suddenly by changing the sounding quantity of a musical sound generating channel of the side for sounding preferentially of one of the previous key-depression or a new key-depression to a synthesized sounding quantity when a continuous depression is detected. CONSTITUTION:Whether a musical sound of the same key as a key which has been depressed newly has been allocated already to a musical sound generating channel by the previous key-depression or not is detected, and when a continuous depression is detected, the sounding quantity of the musical sound generating channel of the side for sounding preferentially of one of the previous key- depression or a new key-depression is changed to a synthesized sounding quantity. Accordingly, the sounding quantity of the side sounded preferentially in the same key is changed to a synthesized sound and a variation of the sound volume which has been absorbed to the sounding quantity of the priority side is reproduced. In such a way, it is prevented that the sounding quantity increases in vain at the time of continuous depression and the sound becomes low suddenly. |
