Although initially marketed to home organists, it found its way into the hands of such famous musicians as Tony Banks of Genesis, Josef Zawinul, Billy Preston, Vangelis, Tangerine Dream, Gary Numan (his 1980 number one album "Telekon" is heavily built on the Pro Soloist), Anthony Phillips (whose 1977 album "The Geese and the Ghost" took its name from Phillips' nicknames for two sounds produced by the Pro Soloist), John Entwistle, and Steve Walsh of Kansas (particularly on the 1975 release "Song for America"). Dennis DeYoung of Styx (used it through 1976 featured on the songs "Suite Madame Blue", "Crystal Ball" & "Man of Miracles"). Banks used the Pro Soloist prominently on the Genesis albums "Selling England by the Pound" (1973) through to "Seconds Out" (1977). It was also used by Funk keyboardist like Junie Morrison on the Ohio Players song "Funky Worm" and by Bernie Worrell in the Parliament "Mothership Connection" (1975) album. Around the same time, the company released its ARP Odyssey synthesizer, a powerful duophonic instrument, as the flagship of its performance line. The Pro Soloist offered an easier-to-use alternative which appealed to professionals as well as home users.
