Robert Miles

In this photo of Robert Miles' studio as seen on the ATC speakers website you can see the blue Focusrite with 4 ISA range preamp channels right above the Red 1 preamps.

From a 2010 article:

From its penthouse location, the studio has spectacular views over the city. Alongside the signature wood panel finishes from designers, Recording Architecture, the room is dominated by stand-mounted ATC SCM100 three-way studio monitors, continuing a theme from Miles‘ previous studio in west London, which featured the larger ATC SCM300s.

Robert was introduced initially to ATC monitors by Roger D’Arcy of Recording Architecture, who also created the design for the earlier studio. "So many systems sound good when you play the music loud, but not as good when you work at low volume. ATC monitors maintain the quality sound at low levels. That was mainly what I looked for because, spending 16 hours a day in here, I like to mix my music at a low volume. In this respect, ATC really works for me. Many well-known brands of monitors will alter the sound. An ATC speaker doesn’t have any coloration. What you hear is the truth."

In a video by Zed AudioLab on YouTube, it is demonstrated that Robert Miles used the Kurzweil K2000, featuring its original piano preset. Also, K2000 contains "Press for Thunder (129)" preset, which was used in his track "Children."

Robert Miles utilizes the Korg 01/W FD in his track "Children." The piano sound in the song is identified as the "16' Piano" patch from the 01/W. This is corroborated by a YouTube video by Urry Kurtz titled "Korg 01/WFD Programs A00-A99," where the A01 Acoustic Piano Patch, known in the manual as "16' Piano," is demonstrated. The sound produced in the video matches the piano from "Children," as verified by a comparison using the 01/W Pro X.
