The Buchla 200e modular can be seen in Deadmau5 studio pictures from this Synthtopia article.

In the Kreativ Sound feature titled "Chemical Brothers – Tom Rowlands – In Studio," Tom Rowlands is shown in his studio with a Buchla 200e System 5 modular synthesizer visible in the background. This synthesizer contributes to the unique sounds found on The Chemical Brothers' records. A clearer image of another Buchla 200e System 5 can be found at Record Production, further demonstrating Rowlands' use of this gear.

He uses a slightly modified version of this, as you can see in the video it's basically the same but a few of the modules have been moved from one side to other other or replaced, as you would expect from anyone who owns such a modular and customisable piece of equipment!

Following high school, she began a programme in Electronic Music, but it was her encounter with the Buchla 200 system during her studies at the Royal College of Music, Stockholm, in 2013 that really set her down the path of electronic composition. "The Buchla taught me a way of listening to sound that years of training in classical music never taught me. Suddenly I started hearing all this subatomic dance of particles wrapped in a waveform. And that’s how all started.” says Barbieri.

Working closely with the late Don Buchla, Ciani became one of the most talented and promotional voices for the pioneering “West Coast” Buchla modular synthesizer. Ciani continues to inspire with her mastery of the Buchla 200e, which she uses both in the studio and for live performances.
