A variety of instructions are inputted through different input modes on a single touch panel. Calculator 22 calculates the coordinates of the contact point on the touch panel 91. Area table 24 has a flag assigned to each area in each image for indicating that the segment is a continuous press input area. Area identifier 25 examines the area table 24 whether the contact point on the panel is in the continuous or the instant touch input area. Examined area attribute is saved in an input mode storage 26. When receiving the mode data from the storage 26 and the coordinates, a screen controller 20 switches the image to another or updates the settings and graphic item in the image. In response to the mode data of the storage 26 and the coordinate data, a parameter setting 27 modifies the parameters of the envelope or effect.
