To obtain the degree, Takahashi completed a four-year-long course that culminated in a project on "the distortion behaviour of transistor differential pairs".
[4] As Korg's chief engineer, Takahashi was responsible for the creation of the Minilogue, Monologue, Monotribe and Volca synthesisers, as well the reissue of the ARP Odyssey and the MS-20 Mini.
For this project, Takahashi created 100 synthesisers designed to output sine waves at different frequencies associated with the musical note A.
[2][8] In 2018, Takahashi worked with Red Bull Music Academy to create a video game based around synthesisers, named Tats.
Alongside Gerhard Behles of Ableton and Cliff Chase of Fractal Audio, the list compared Takahashi to the likes of Robert Moog and Don Buchla, who were early pioneers of the synthesiser.
