Jeff Mills

25:45 Jeff Mills is using Roland TR808 for live jamming, this is my first time see him use 808 for live

Per this MixMag feature for 909 Day, 2018:

At first, my main drum machine was not the Roland TR-909. It was the Akai R-15, and I moved to a TR-707 next, because that was more affordable at the time. And then to the 727, because percussion was really happening at a certain point. I didn’t get my hands on a 909 until 1986. It was for a band that I was connected to but the music was not techno—it was an industrial band. So I needed a machine with robust sounds, pipes and all types of really strong sounds—and that was my first contact with the 909.

In a user-uploaded photo on the Arturia website, Jeff Mills is shown using the Arturia BeatStep Pro, highlighting its role in his creative process.

In a video shared on his official Instagram account, Jeff Mills is seen using the Roland TR-909 Rhythm Composer.
