Don Airey is confirmed to use the Casio FZ-1 Sampler as part of his live instrument line-up, described in the article "Living in the Past" from Music Technology's February 1988 issue, where the instrument is mentioned among his equipment. Airey characterizes his setup as "something old, something new, something borrowed," and the Casio FZ-1 is noted as a current favorite during a pre-show examination of his keyboard riser.

Atari Teenage Riot's 1995 album was produced by Alec Empire and lists the following instruments in the liner notes: "This album was recorded with an ATARI 1040, a CASIO FZ-1 sampler and a TR-909 drummachine... Sorry but we had to use the AKAI S-1000 sometimes for timestretching"

Alec Empire can be seen playing a Casio FZ-1 in the music video for "Speed" from the same album. He also tweeted in 2014: "that is such an old track hehe done on a Casio FZ1 sampler ;)"

In the 33 1/3 publication They Might Be Giants' Flood, on page 74, John Linnell reports that he and Flansburgh each acquired a Casio FZ-1 for the writing and recording sessions for that album.

Mundo Muzique cites the gear used on "Mentasm" in this RedBull Music Academy Interview:

In Joey’s Studio we used an Akai MPC60 drum machine, Casio FZ-1 sampler, Alesis effects, Mackie 32-8 Mixer, and Tascam DAT recorder. We both had more gear than that, but those were the important pieces for the “Mentasm” project.

"We also use quite a lot of old stuff, because I've still got things like a PPG 2.2, and we've used a Prophet 5, Juno 106 and Jupiter 8 because there's a lot of arpeggiated stuff. A big problem with a lot of modern sequencers is that you have to write arpeggiation in yourself- there isn't actually a machine which arpeggiates, which is a shame because it's nice when it's more random. We use S1000s, S900s, and an FZ1. I tend to use the FZ1 as my main sampler just because that happened to be the one that I bought."
