The Chemical Brothers, specifically Tom Rowlands, utilize the Elka Synthex to craft their distinct sound, as highlighted in the Kreativ Sound article, "Chemical Brothers – Tom Rowlands – In Studio."

Album credit: Jarre used the Elka Synthex on tracks such has "second rendez-vous".

In the video titled "Mike Dean Building a Track Is Analog Synth Mayhem | The Process" by Reverb on YouTube, The Real Mike Dean demonstrates the Elka Professional Synthex by playing a few chords.

According to this December 1999 Sound on Sound interview with Paul Wiffen, Wonder owns the last produced Synthex (made from spare parts) and used it on "Skeletons".

Unfortunately, by the time my guerilla marketing started to pay off - getting the Synthex on TV with players like Peter Oxendale in Bonnie Tyler's 'Total Eclipse of the Heart', Mark Stanway of Magnum and Phil Lynott in Grand Slam - Elka had lost faith in the instrument and were selling it off directly for £500 through the music technology magazine Electronics and Music Maker. Some people got a magnificent bargain, considering the original retail price was over three grand. As payment for programming work on some hideous FM-based unit that Elka came out with (my mind has deliberately blanked out the model number), I got Elka-Orla to give me two of the last Synthexes and to ship one of them to Los Angeles, where I was moving. Called in to try to make sense of Stevie Wonder's new Sequential Studio 440 drum machine (into which my Prophet 2000 samples would thankfully load), I was soon up to my old tricks, asking if I could bring in other synths. Next thing we were MIDIing the OSCar and Synthex together for the killer bass sound on his 1987 single 'Skeletons' and I was in there. After the album's release, I toured the world with Stevie as MIDI programmer, ensconced under the stage with the Synclavier guy. Unfortunately, because of their limited MIDI implementation, neither the Synthex nor the OSCar went on the road (except recorded into the Synclavier), but Elka-Orla cobbled together one last Synthex for Stevie from several ones that had been cannibalised for parts (because I refused to sell him mine).

According to this interview, Vitalic made his fist album with only 3 pieces of equipment: "When I made the EP I only had an Elka Synthex, a Mirage sampler - even though I don't really consider that an instrument - and an RSF Kobol…""

The first synthesizer shown in Ulrich's "Studio Tour" video by MusicTech is a Elka Synthex. This can be seen at :07s with Ulrich saying "it’s a polyphonic synthesizer from the 80s - it has a quite a particular sound."

Nick pictured using Synthex during recording.

"Fun machine! The step sequencer that is built in is a blast."

In this video, it is mentioned John Carpenter has used the Elka Synthex when composing his famous horror movie scores

"I've had nearly all of my analogue synthesizers modified for MIDI including the Minimoog and the Elka Synthex; though modifying a synthesizer that was built ten years ago isn't exactly easy..."

Tore Ylwizaker was seen using the Elka Synthex during a performance at the Norwegian National Opera House, as evidenced by a user-uploaded photo on Wordpress.
