There are provided first and second tone signal generation channels for respectively generating tone signals having waveshape characteristics corresponding to parameters assigned thereto. Tone color change control information such as key touch data is applied to a parameter assigning circuit. The parameter assigning circuit selects two parameters from among three or more parameters which are different from one another and assigns the selected two parameters to the first and second tone signal generation channels respectively. Tone signals having different characteristics, which are determined by the assigned parameters, are generated from the respective channels. The tone color change control information is further applied to an interpolation circuit connected to the first and second channels. The interpolation circuit interpolates the generated tone signals in accordance with the tone color change control information. A result of the interpolation is outputted as a tone signal for a tone to be produced. |
