Abstract: Each parameter is provided with increase/decrease switches and a slider. In a case where a user desires seamless rough control of the value of a target parameter, the user is to use the slider. In a case where the user desires easy control of the value of the parameter with the smallest unit of the resolution, the user is to use the increase/decrease switches. Since the slider specifies a parameter value in accordance with the position of the manipulated slider, the range within which the parameter value can change is determined on the basis of the current parameter value and the maximum value and the minimum value of the parameter. Because the increase/decrease switch increases/decreases a parameter value by “1” at each manipulation, the range within which the parameter value can change by a single manipulation of the increase/decrease switch is “±1”.
