PROBLEM TO BE SOLVED: To provide a musical sound producing device to provide a musical sound having a loopback distortion intentionally as a kind of effect. SOLUTION: Sinusiodal wave data output means (1a, 1b,...) individually provide a digital data representing a sinusoidal wave. A frequency setting mean 2 sets information on a frequency which is an integral multiple of the lowest frequency to each of the individual sinusoidal wave data output means (1a, 1b,...). An adder mean 3 digitally adds digital data provided from the sinusoidal wave data output means (1a, 1b,...). A loopback distortion allowing mean 4 enables/disables the sinusoidal wave data output means (1a, 1b,...) to provide digital data that are loopback distortions in a form of sinusoidal wave at audible frequency for the digital data of sinusoidal waves with frequencies specified by the information from the frequency setting means 2. |
