In an interview with Red Bull Music Academy, Jean Michel Jarre mentions the Roland JD-800 Synthesizer as one of his favorite synths.

Liam Howlett once acquired a JD800, though he says he quickly regretted his decision: "I played a JD800 in a shop, and thought it was pretty cool; it seemed to have the analogue feel. So I thought I could get all the analogue sounds on other equipment (...) When I got the JD800 home, I knew within a week I wasn't happy with it. I'm definitely getting the Minimoog back!"

He's also using a Roland JD800, Korg T2 and Yamaha SY77 and SY99 - a nice selection of electronics, if you can afford it.

"For touch‑sensitivity, I used the brand new Fatar keyboard. Close your eyes and it really is like playing a piano. All of the piano on the album is real piano [a Steinway 9‑foot]. For soloing, my favourite keyboard is the Minimoog. After the Minimoog, my second favourite is the Roland JD800, which I MIDI up with other instruments. It's interactive — I love being able to fiddle with the knobs as I play. From Roland's point of view the machine was almost a total disaster. They brought it out at a time when people didn't want to play around with sound, but that's all changed. I have a sneaking suspicion that the JD800 will be discovered by some spotty little 19‑year old, who thinks 'this is great' — it'll appear on Top Of The Pops, and then we'll all be searching for JD800s! Other favourites include Korg's 01W ProX and X5DR."

Music Radar, July 14, 2020, "Rick Wakeman on his top 5 synths: 'I suddenly had an instrument that could give the guitar a run for its money'"

“I hope you’ll indulge me with one digital machine. By the time the ‘90s came around, synths were getting pretty boring. It was all about presets. Here you go, lots of lovely sounds that we’ve programmed for you. I didn’t want that. I wanted a synth that you could get your teeth into.

“This was the first digital one that reminded me of the early days… plenty of knobs and sliders to play with. And even though it was digital, it had some nice, analogue-y sounds.

Tony Banks can be seen using a Roland JD-800 Synthesizer at 0:43 in this video of Genesis performing 'Dance on a Volcano/Firth of Fifth'.
