| − | [[Image:Ym2413.jpg|frame|right|Yamaha YM-2413]]The '''YM-2413''', also called '''OPLL''', is a very low budget sound chip manufactured by [[Yamaha]] and based on their YM-3812 (OPL2). To reduce manufacturing costs of the chip, many of the internal registers were removed. The result of this is that the YM-2413 can only play one user defined instrument at same the time. The other channels have to play one of the 15 built-in instruments. There were other cost cutting modifications such as having only 2 waveforms, and not having the channels added together - instead, the chip's DAC plays each channel one after the other, and the output of this is usually passed through an (analog) filter. | + | #REDIRECT [[sega:YM2413]] |
