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.

Also used by Brian Wilson on "Love You" by The Beach Boys. The 'Trumpet' and 'Steel Drum' Presets can be clearly heard on "I'll Bet He's Nice", for example.

I opened for Bernie Worrell on friday; he's touring with an ARP Pro Soloist 2701 & it sounded exactly like Funkentelechy Vs. The Placebo Syndrome.

I've just acquired one of these (for a sensible price) having wanted one for ages- after a full stripdown and service everything works nicely and the sounds and playability are all I had hoped they would be. A clever and beautiful-sounding instrument, only let down by ARP's inability to QC their soldering and that rubbishy hardboard baseplate- now binned and replaced with good honest aluminium. I love this thing :-)

The Pro/DGX has horrible rocker switches and generally looks and feels like something that should be left for dead under some granny's bed forever. That's until you flick it on (after clearing it of internal dust, hopefully) and play it: e.g. the oboe, french horn and cello with a bith of external analog delay and spring reverb will make you sound like a mini-Vangelis in no time. The aftertouch makes it a highly playable little mono, with a vastly (and sadly) inflated price due to the ARP name.
