Turner can be seen in this photo with a Farfisa Combo Compact organ.

John had a red Farfisa Combo Compact organ in his home studio.

In the early days of the band, Wright dabbled with brass before settling on Farfisa electric organs as his main instrument onstage. He originally owned a single-manual Combo Compact model, which was used for early recordings of "Interstellar Overdrive",[67] and later upgraded to a dual-manual Compact Duo. During the 1960s, Wright relied heavily on his Farfisa fed through a Binson Echorec platter echo, as heard on the Ummagumma live album.[66] On later tours, the instrument was fed through a joystick control allowing the signal to be sent through up to six speakers in an auditorium, which was called the "Azimuth Coordinator".[71] Wright stopped using the Farfisa after The Dark Side of the Moon, but revisited it in later years, playing it on Gilmour's On An Island tour. It was recorded for the sessions that eventually became The Endless River.[72]

Wright's Hammond M-102 organ, used on Pink Floyd: Live at Pompeii. Wright played the piano and Hammond organ in the studio from the start of Pink Floyd's recording career; using the Hammond's bass pedals for the closing section of "A Saucerful of Secrets".[73] He used a Mellotron in the studio for some tracks, including Ummagumma's "Sysyphus" and on the "Atom Heart Mother" suite. For a brief period in 1969, Wright played vibraphone on several of the band's songs and in some live shows, and reintroduced the trombone on "Biding My Time".[74] He started using a Hammond organ regularly on stage alongside the Farfisa around 1970[75] and a grand piano became part of his usual live concert setup when "Echoes" was added to Pink Floyd's regular set list. All three keyboards are used in the concert film Pink Floyd: Live at Pompeii.[a]

In the 1970s, Wright began using synthesizers such as the VCS 3, ARP String Ensemble and Minimoog, which were featured on "Shine on You Crazy Diamond". Wright wrote the closing part of the track alone, and included a brief extract of the band's early single "See Emily Play" on the Minimoog towards the end.[79] He used a number of electric pianos during the 1970s, including a Wurlitzer fed through a wah-wah pedal on "Money"[80] and an unaccompanied Rhodes introduction for "Sheep" on Animals.[81]

From the 1987 Momentary Lapse of Reason tour onwards, Wright and touring keyboardist Jon Carin favoured Kurzweil digital synthesizers, including the K2000 keyboard and K2000S rack module for reproducing piano and electric piano sounds.[82] Wright retained the Hammond along with a Leslie speaker, playing it onstage and using it during the Division Bell sessions.[83]

In this photo from 1967, Wilson can be seen playing a Farfisa Combo Compact organ backstage with the Beach Boys in Hawaii.

Philip Glass is seen in the 3rd and 5th photographs on this interview page sitting behind a Farfisa Combo Compact organ (probably the grey version). It seems very likely that the bigger Combo Compact was too troublesome to repair, too expensive to acquire, or too much organ for what the ensemble required and so the smaller Mini Compact was seen more often in live and rehearsal media of the PGE during this time. Philip Glass writes about such topics in his 2015 memoir "Words Without Music."

John Linnell played a red Farfisa Compact in the early days of They Might Be Giants, as well as in his previous band, the Mundanes. It was used on many very early demos and some studio recordings, most notably "Twisting". There are no known usages of this organ by John Linnell beyond 1990, although it's possible it might've seen use on Apollo 18.

Sly Stone can be seen here playing a Farfisa Combo Compact with Sly and The Family Stone. The photo looks to be from the band’s early years, and Sly would later use the Farfisa Professional organ as his primary touring keyboard.

In the video titled "Jellyfish's 'Bellybutton' | Inside the Album with Roger Joseph Manning Jr. - Produce Like A Pro," at the 4:29 mark, Roger Joseph Manning Jr. discusses using the Farfisa Combo Compact organ in the song "The Man I Used to Be" from the album Bellybutton. This serves as confirmation of the instrument's use by the artist, as documented by the source, Produce Like A Pro.
