BT still adores his heavily modified Roland TR-707, the Roland TR-505, the Roland 505 and the Boss DR-550 MkII. "Anything with that many switches has to sound good," he says with a laugh.

Roland TR-707 Rythm Composer The Roland TR-707 Rhythm Composer is a programmable digital sampling drum machine built by the Roland Corporation, beginning in 1984. The TR-707 was a staple in early house music, particularly with acid house. Because the TR-707 offers a limited number of instruments sampled at 12 bits, its sound is considered dated by modern standards. However, it is still in use because of its versatility in synchronizing with other hardware and its fully featured interface, comparable to that of high-end Roland drum machines such as the TR-808 and TR-909.

Used:

Liam has told that this machine was used to produce drums for Invaders Must Die single. He has probably used it also in many more older tracks too.

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.

"here I`m playing around with a Roland t.r. 707 drum machine and more specifically the Tap Write function on the sequencer (a feature, which I discovered just recently)."
