Pro Soloist

The Pro-Soloist is a thirty preset monophonic analog synth from the early 1970's, originally designed to sit on-top of, and accompany a large Organ. It had 30 preset sounds to choose from, including Flute, Bassoon, Brass, Fuzz Guitar etc. Other features included pitch, portamento, vibrato, growl and wow effects. The keyboard has 37 keys with aftertouch sensitivity for volume, brilliance, vibrato, wow, and even bend effects. A few basic filter (brilliance), envelope and LFO controls allow some tweaking of the preset sounds, however there is no memory to store your settings.

The Pro-Soloist is a compact and basic monosynth best suited to leads. Because of its aftertouch feature, it's simply one of the most playable and expressive solo instruments Arp ever made. It was later followed up by the Pro/DGX in 1977. The Pro-Soloist has been used by Tangerine Dream, Tony Banks (Genesis), Coldcut, Gary Numan, Herbie Hancock, Patrick Moraz, Billy Preston, John Entwistle, Billy Preston, and Vangelis.

The Pro-Soloist was based on the Soloist from 1970/71. The Soloist - also designed to sit atop an electronic organ - had its preset sound selection switches located under the keyboard in the same tradition as the Roland SH-1000/2000 and Elka Soloist synths.

Another user of the Pro Soloist is Anthony Phillips (guitarist/composer and Steve Hackett's predecessor in Genesis). You can hear the synth quite a bit on "The Geese And The Ghost" (his 1977 debut solo LP), and according to the sleevenotes of the 2008 CD reissue, the album's title derived from Ant's nicknames for two of the PS sounds on the title track.

Lots of people like Tangerine Dream and Klaus Schulze used a "string machine" called the Elka Rhapsody. It was supposedly related to its ARP Solina and Omni brethren (and probably wedged in between the two in quality and popularity), but in looks it was actually very similar to the ARP Soloist.

I'm kind of curious about this. All three members of Tangerine Dream from 1972-77 (at least) used an original Soloist, but then TD founder Edgar Froese switched over to something listed in the personnel as "digital Soloist synthesizer." I would think that this really means the Pro-Soloist.

The Arp pro-soloist synthersizer was the one used by tony banks of genesis for all I know it was used one of genesis album "seconds out" recorded live in 1977 & usually he uses the arp 2600 synthersizer on other recorded albums when he first appeared his synth on "Selling england by the pound" back in 1973.
