From a Sound On Sound article, the Waldorf Microwave XT Synthesizer can be seen in Zimmer's large rack of synths in his studio (http://www.soundonsound.com/sos/oct02/articles/hanszimmer.asp).

Part of Karl Hyde's Studio.

"I have the Juno-60 that I mentioned, an Alesis Andromeda, which is very popular these days. Everybody's putting out analogue synths again and the Andromeda is a late 90s synth but all analogue. It's probably somewhat anachronistic today because there's so much around like it now, but I love how it sounds. I have a Waldorf Microwave XTC that I worship and control with a software editor called Monstrum XT that allows me to randomise its parameters, as I'm not very good at programming synths. I've also got an Elektron Analog Four, but the rest of the stuff's been decommissioned. If I'm not using something, I tend to sell it and move on, so I'm not too sentimental about hardware synths."

In the Synthtopia article "Vince Clarke And The Temple of Synth," Vince Clarke is noted for using the Waldorf Microwave XT Synthesizer.

In this article from Trash Audio Venetian says his latest piece of gear was "a Waldorf Microwave XT off this guy I know a couple months back. It’s in my rack where my Prophet 08 with the world’s wonkiest pots used to live. I’m pretty into what you can do with multis, can take 8 patches and layer them together in really interesting ways."

"In addition to the ever-present Fenix (going through OTO Biscuit pedals), Goldwasser also had control of the Roland Chorus Echo delay guitar effect pedal, the Waldorf Microwave, and a rackmount Jupiter."

Underneath a picture (second half of article) of his private studio for Massive Attack it says: "The keyboards at the far end are a Moog Prodigy, a Waldorf Microwave XT, and a Roland Juno 60"

In terms of keyboards, Vrenna notes, “I just like big, shiny keyboards with lots of lights. My sampler is still an E-mu: the E4 Ultra. I still use it every day of my life. They discontinued them because they've gone software, as well with the new E-mu X Series, so I've been picking up used E-mu's out of the Recycler and eBay and building a couple more hardware samplers just so I have them.” His arsenal also includes a Waldorf Microwave XT, Kurzweil K2000/R, Roland V Synths, an old Virus updated “as far as it will go,” a Nord Lead 2, Alesis Andromeda A6 and “a good old trusty JP8000.”

In a studio tour video on YouTube by FanScooterchannel, Scooter is shown using the Waldorf Microwave XT Synthesizer.

The producer states: "Weiterhin haben wir häufig die Roland SH-101, den Waldorf Mircowave und den Clavia Micro Modular sowie alte Samples vom Ensoniq ASR-10 eingesetzt." You can see the yellow rackmount synth in the last pics at the bottem of the interview.
