The present invention provides a flat panel display device, which includes a backlight system and a display panel. Lead tips on one side near the semiconductor die are electrically connected to bonding pads on a main surface of the semiconductor die via gold wires, and lead tips on the other side are ended at a side surface of the plastic package. Consequently, it is possible to reduce the width C of the recess, thus resulting in a stabilization of the knitting machine needle in this region. A musical tone of each tone pitch indicated by the supplied performance information is assigned to a corresponding one of the tone generators according to a pitch name corresponding to the each tone pitch. One clamp has a motorized trolley that provides adjustment needed for handling chassis of widely varying wheelbase. The value that is retrieved from the table is used to derive another value that is combined with multiple other values in the sequence to generate the next number in the sequence.
