The OPL (FM Operator Type-L) series is a family of sound chips developed by Yamaha. It consists of low-cost sound chips providing FM synthesis for use in computing, music and video game applications.

2024年6月28日 · The Yamaha YMF262, also known as the OPL3 (OPL is an acronym for FM Operator Type-L), is an FM synthesis sound chip by Yamaha. It is an improved version of the Yamaha YM3812 (OPL2). The YMF262 was used in many ISA [note 1] sound cards, including the Sound Blaster Pro 2.0, Sound Blaster 16 ASP and AWE family. [1]

YMF289B (OPL3-L) is a synthesizer chip developed specially for note PC, PCMCIA (type II) card. YMF289B is compatible with YMF262 which is de facto standard in sound card market. Special functions (power down mode, 3.3V power supply and etc.) are newly featured.

This software package provides FM synthesizer plugins, based on OPL3 and OPN2 sound chip emulations. The emulations and the drivers are provided by libADLMIDI and libOPNMIDI.

Released in 1988, the YMF262 is also known as "OPL3". An extended version of the original OPL2 chip (the YM3812), it basically had the capabilities of two YM3812 chips in one. It was designed as a replacement for the twin-OPL2 arrangement fitted to the earlier Creative Sound Blaster Pro cards.
