In the video "Tame Impala 'Lonerism' Episode 2" on YouTube by Modular YouTube, Kevin Parker is seen playing a Sequential Circuits Pro One Synthesizer at the 1:00 mark. Initially, there was a mix-up, as it was thought to be a Prophet 600.

Per this March 2001 interview with Keyboards Magazine (FR), Daft Punk employed a Sequential Circuits Prophet 600 during the recording of Discovery.

In this article it says Justin Vernon (Bon Iver) used an Prophet 600 when recording his last album, 22, A Million

BT tweets a photo of his modded Sequential Circuits Prophet 600 synth, which was built in 1983.

He writes "Behold the beauty of a firmware modified, re-contacted Prophet 600. Best part signed 'Assembled by Randy 1983' #Epic" (posted by BT on 13 Jan 2015).

This Electronic Musician article states that Murphy owns a Prophet 600.

At the 3:07 mark of "Carl Craig – Modular Pursuits", this synthesizer is seen just to the right of the Prophet 5 in the lower-right hand corner of the shot.

"A gritty raw sounding analog synthesizer with lots of knobs to make programming easier. Its a bit dim witted or slow for that matter; you can hear the 127 digital controller steps when you turn the knobs and the envelopes aren’t that smooth…but it sounds quite nice and has that typical Sequential sound."

Rob Swire can be seen using a Sequential Circuits Prophet 600 Synthesizer in the provided image. Although it's partially obscured below the keyboard stand, discussions with synth enthusiasts on Reddit have confirmed its identification.

"It's mostly Eurorack, but I have a classic Moog Voyager and a Synthesisers.com set up that emulates the old Moog 5U modular system. Then I have things like the TTSH (Two Thousand Six Hundred), which is an ARP 2600 replica, an original Roland System 100M - I love the way that thing sounds, a Roland Juno-106, a Juno-160 and a couple of Prophet 600s. I also have a Buchla set up, and a Swarmatron, which I use a fair amount as well, so I can kind of do anything I want."

From a Synth History article written by Roger O'Donnell:

Early in 1983, Sequential Circuits, under the guidance of its guru, Dave Smith, whom I later became close friends with, released the Prophet 600, the first instrument with MIDI. A huge landmark for synthesizers, recording and even washing machines! I don’t think any of us realized at the time how important MIDI would become and how it would change our lives as musicians, we just saw it as a way of one keyboard being able to control another. Dave didn’t patent it, it was a gift to the world, one of those moments when the greater good was more important.

The 600 itself was like what the Micro was to the Minimoog, a paired down budget version. When the Prophet 5 first came out, it was about the same price as a small apartment in London, I think the 600 was around £1200? Sonically, it was great, the only downside was that the filter wasn’t as smooth as the 5, you could hear it step if you swept it. It was 6-note polyphonic, so you could play a nice sized chord. It had preset memories, a short un-clocked sequencer, which was a sort of musical notepad and one feature I really liked was a latch button. You could latch a chord and then play it with one finger.

This was the keyboard I used when I first joined the Thompson Twins. In fact, on the first tour of the US opening for The Police on the Synchronicity tour, I didn’t even have a flight case. It stayed in its original shipping box. I used this keyboard throughout my time with the Twins and then with the Furs through until 1987. I still have this one too.

For performance of the "Night Owl" live at BBC Radio 6's live room, Mount used the Sequential Circuits Prophet 600.
