Ym2413+instrumentsbin May 2026
The YM2413, also known as the OPLL (One-Period Linear Programming), is a audio chip developed by Yamaha Corporation. It was widely used in various applications, including video game consoles, computers, and arcade machines, particularly in the 1980s and early 1990s.
However, the actual YM2413 user instrument register map (1 instrument = 8 bytes):
Its unique character and limitations have recently gained renewed interest through projects like YM2413-MDB, a comprehensive dataset of 80s video game music designed for research into emotion-conditioned music generation. Technical Architecture and Limitations ym2413+instrumentsbin

The instruments.bin file is the gateway to unlocking custom audio on the Yamaha YM2413. By understanding how the 8 bytes of register data control the 2-operator FM synthesis, users can significantly expand the sonic capabilities of the OPLL, pushing the boundaries of 8-bit sound design.
