<p><P>PROBLEM TO BE SOLVED: To continuously reproduce music in a specified time period without largely increasing control loads. <P>SOLUTION: On a performance control board, in addition to a CPU (central processing unit), an ADP (audio processor) for synthesizing the sound of music data and reproducing the music on the basis of a command from the CPU is loaded. When starting big winning control, the command of starting the reproduction of big winning music and the command of adjusting a reproduction level are issued from the CPU and the reproduction of the music is made to fade in and started by the ADP. When starting each round in the big winning control, a reset signal is outputted from the CPU to initialize the internal state of the ADP, the command of starting the reproduction of the big winning music and the command of setting a maximum level are issued from the CPU, and the reproduction of the big winning music is started at the maximum level from the beginning by the ADP. When ending the big winning control, the command of ending the reproduction of the big winning music and the command of adjusting the reproduction level are issued, and the reproduction of the music is made to fade out and stopped by the ADP. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
