Takayuki Iwabuchi is a Japanese sound designer and programmer. He joined Hudson Soft around 1987. During most of his career, his credits included sound programming and design. His most significant contributions included programming the audio engines used by Hudson Soft including the TurboGrafx-16 and SNES. He stayed with Hudson all the way until they were bought by Konami. Tetris Axis for the Nintendo 3DS appears to have been his last game, and it appears he retired from the game industry afterwards.

Audio Development


For the TurboGrafx-16, Iwabuchi programmed a sound driver, likely in 65C02 assembly language. According to various sound designers, the music was written on a PC-9801 in a custom Music Macro Language, and subsequently assembled for playback on the target console.

Iwabuchi used several aliases throughout his career, possibly at the behest of Hudson. He was usually credited as Lu Iwabuchi. The etymology for this name is unknown.

AX-1 Iwabuchi most likely refers to the Roland AX-1, a keytar made by Roland Corporation.
