Yamaha YM2413

The YM2413, also called OPLL, is a cost-reduced sound chip manufactured by Yamaha Corporation and based on their YM3812 (OPL2). To make the chip cheaper to manufacture, many of the internal registers were removed. The result of this is that the YM2413 can only play one user-defined instrument at a time; the other 15 instrument settings are hard-coded and cannot be altered by the user. There were other cost-cutting modifications: the number of waveforms was reduced to two, and an adder is not used to mix the channels; instead, the chip's DAC plays each channel one after the other, and the output of this is usually passed through an analog filter. The YM2413 was used as a sound expansion on the MSX and the SG-1000 Mark III. Also, the Famicom game Lagrange Point contained the Konami-designed VRC7 mapper circuit, which had an FM sound core quite similar (but not identical) to the YM2413.
