"There's a couple of photos on the inside of the album of me with the EMS Synthi 100; I think there's only about four in existence. Jack Dangers from Meat Beat Manifesto bought it from the University of Adelaide - it's one of these modular synths that takes up a whole wall and you look like you need to wear a lab coat just to operate it. So I had several sessions at his place. Much in the same way as sampling and synths have a vocabulary and a feel, Ableton and doing things in the box has a precision, and when you merge all of those that's when good things happen."

EMS Synthi 100 is included in the list of synths at Daniel Miller's home studio.

"Yeah, it’s the equipment we use as well, like the EMS, the Synthi ATS and the Synthi 100 has a sound which I suppose gives a British sound because it was in the year that British synthesizer / modular manufacturers back then would just support bands to use their gear through the years."

“One of the cornerstones of the collection is this custom-made Synthi 100 by EMS, together with the big EMS Synthi Vocoder. Peter Beste”

In an article by bant mag, Irmin Schmidt is featured with the EMS Synthi 100, highlighting his use of this modular synthesizer.

"Elizabeth is one of a handful of composers who went from using reel-to-reel tape recorders in 1978 through to running an entire studio contained in a single computer set-up in 2008. From cutting up tape, making loops of sound and using the Synthi 100 and VCR3 to create the Blake’s 7 sounds,"
