PURPOSE:To obtain an excellent sound source for an electronic musical instrument by adding N signals stored in a memory and calculating their arithmetic means. CONSTITUTION:A signal at every time length which is a prescribed integer times the fundamental period of a musical sound signal in a steady part in the musical sound signal generated corresponding to a musical sound pronounced from the musical instrument is read out of the memory 39 and latched by latch circuits 40(1)-40(N), the data latched by the latch circuits 40(1)-40(N) are added by an adding circuit 41 at the same time, and a dividing circuit 42 calculates their arithmetic means to obtain the source musical sound signal. |
