"My studio was called Pi West, and the initial bank of keyboards there when John and I started out working together were the Sequential Circuits Prophet 5 Rev3, a Prophet 10, an early ARP Quadra and two ARP Avatars — one Avatar was integrated with a Sequential Circuits Model 700 programmer — an ARP Sequencer, an Oberheim Four Voice, and an Emulator 1 sampler. I also had the Linn LM1 drum machine, which drove our main arpeggiator, the ARP Sequencer, using clock pulses."

In this scan of a Keyboard magazine feature, Steve Porcaro mentions using an Oberheim 4 voice for the slide-ups in Michael Jackson’s "Human Nature".

"Zawinul did not stop at the Wurlitzer and Fender Rhodes electric pianos he used in the 1960s. By the late 1960s he was extending his sonic palette with effects like phase shifters, Echoplexes, wah-wahs and ring modulators, and when synthesizers came on the market he was among the first to buy one (the EMS Putney). The list of synthesizers he has used since then — among them the ARP 2600, Rhodes Chroma, Oberheim Four-voice and Eight-voice, ARP Quadra, Sequential Prophet 5 and Prophet T8, Korg Trident, Oberheim Xpander, Korg VC10 vocoder, Emu Emulator, Casio CZ101, Korg DW8000, DSS1, DSM1 and M1 — reads like a synth museum's treasure list."

from Contemporary Keyboard Magazine, July 1977:

"When did you start getting into the polyphonic synthesizer?

Well, as I said, I just got the Oberheim recently. I tried out a bunch of them—the Oberheim, the Polymoog, the new Yamaha unit that will be out soon. All of them are great; but so far I like the Oberheim best, so I'm working with it"

In the article she clearly states: "Neben einem Oberheim Four Voice habe ich mich dort sofort in den ARP2600 verliebt." The Oberheim is also referred to in other articles...

In this video a pair of Oberheim FVS synthesizers can be seen as a part of Michael’s set-up live with the Doobie Brothers in 1977.

In this music radar article, it mentions Mays originally used an Oberheim Four Voice while with the Pat Metheny Group.

In this video you can clearly see him using a FS-1. He also has 4 additional SEM’s to the left to create an 8 voice.

"There's also the Oberheim 4-voice which is a wicked sounding synth. Each voice has two oscillators, and it sounds like it looks really - you can blow holes in walls with it! The main riff on 'Timebomb' features one of those."

Phil Oakey of The Human League is listed as using the Oberheim FVS-1 Four Voice synthesizer in the Sounds article dated August 12, 1978, featured on The-black-hit-of-space.

Roger Hodgson and Rick Davies used this on Breakfast and on the Paris concert

Dennis used a four voice Oberheim synth on The Grand Illusion album.
