This Promars here is a pretty rare synth – it’s basically a monophonic Jupiter-4.

The list of synthesizers that the radiophonic workshop used in 1985

Recording with Elvis Costello over a period of more than three decades, Nieve has explored a variety of keyboard sounds and has used a wide range of keyboards from grand pianos to vintage synthesisers. The first keyboard he owned was a Vox Jaguar, which he purchased when he was just sixteen. On early Costello albums such as This Year’s Model and Armed Forces, Nieve was playing classic keyboards like the Polymoog, Jupiter 4, Vox Continental and as some sites have incorrectly documented, a Farfisa organ.

“I didn’t use a Farfisa, that’s not true'” he states. “It was always a Vox and I have always liked playing that organ and continue to play it. I have to keep a collection of them to keep them going. I have two which are just ripped to bits. To be honest, a lot of those old keyboards were usually quite reliable. It’s just if they do go wrong, you have to get them fixed. I usually have a technician with me to handle that aspect. There’s nothing like it because they sound great and are a pleasure to play the way they feel. I’ve continued to use them and probably always will. What I am excited about this new show though, is just being on the piano. It’s my number one instrument.”

"The Roland Jupiter 4 was used a lot — the spaceship soaring away was done with white noise and four-note chords near peak resonance just before oscillation of the filter."

Al Deloner utilizes the Roland Jupiter-4 as a key element in crafting his distinctive sound, as highlighted in a Facebook post for "Transfigured Night."

"Often, the bass parts would be replaced or duplicated with a synth, using a kick drum pulse to trigger Lexxx's Roland Jupiter 4. "It's a bit of a pop trick,” says Fleming. "But we wanted something that sounded more human.”

Christian Bruhn once fetched Timm Thaler's multi-track tape from the shelf just for me to tell me the original instruments from the track plan, I almost passed out with "Unworthiness". He had Kristian Schultze (also a brilliant musician, unfortunately already in heaven) to record the synthesizers, who had recorded the tracks in his own studio and on his instruments, as well as the Captain Future Tracks. A SH-2000 was not there, if you listen carefully you can clearly see the Minimoog. As hard as it is, Schultze had used all the unaffordable super sound monsters for the two soundtracks. So, here is the original information from C. Bruhn from the track plan:

Prophet 5 (Schultze had a rev2), Roland Jupiter 4 (you can clearly hear that on Captain Future), Minimoog, unfortunately actually also a Yamaha CS-80 and a rare Wersi string machine, as well as an eventide h910 harmonizer, the cascading pitch -Effect can also be clearly heard, along with the tape echo flutter.

I hope this clears up a piece of audio history for all Captain and Thaler fans.

Of course, I was also at an appointment for Mr. Bruhn's cinema tour. At the end of the question and answer session he had a piano medley from Cptn for me. Future and Timm Thaler played. Dark hall, I stood wg. my question, everyone else was sitting and Mr. Bruhn was playing for me. I will never forget the moment, 1.5 minutes of complete trance ... Thank you very much, Mr. Bruhn!

Presser Gábor used the Roland Jupiter-4 synthesizer during the recording of the "Electromantic" LP, as confirmed in the April 1983 issue of Electronics & Music Maker.

In the YouTube documentary "The Secret Keyboardist of Robert Plant & Black Sabbath: Jezz Woodruffe" by JCM - Led Zeppelin Stories and more, it is confirmed at 5 minutes and 19 seconds that Gerald Woodruffe used the Roland Jupiter-4 on his solo album "Opposite Directions," as all the keyboards utilized for the album are displayed.

"Analogue synthesizers have a big advantage: you can drill them open. (...) You can't do that with prefabricated software synthesizers." — DUB TAYLOR TECH TALK feature, taken from Slices Issue 1-09

Noting the comedy in there being a button labeled "The Force", Feiner decided to post a close-up shot of his Jupiter 4

But the equipment list for 'Message' is quite formidable - Roland Jupiter 4, Jupiter 6, CSQ600 and TR808, Korg VC10 vocoder and Polysix, Oberheim OB8, DMX and DSX, Elka Synthex, guitars, Simmons kit and Mattel drums. And as you may have spotted during the Trans X single's recent heavy airplay, there's also a bit of Casio VL-Tone on 'Living On Video', and elsewhere. For his own part, Languirand is at pains to point out that this is really a Jupiter 4, but anyone who's suffered the VL1's built-in Austrian Folk Tune a few hundred times can usually spot one a mile off... I know I could.
