"This a collectors gem from 1975. All it does is the classic 70s string sounds AND its polyphonic! If you remember the ARP string Ensemble this sounds very very close to that sound. Used on 1,000 of albums back in the day including Tangerine Dream... Comes with Elka hard case... There are only two setting buttons Cello/Violas and Strings. The Cello works fine however the strings DO work but the output is low."
YouTube via Denkitribe "You can make any analog modeling synthesizer sing with pseudo formant synthesis. Funny singing? I think it's like a speech synthesizer in 70's.
"I have a alpha syntauri synth that has been sat around for years... Can anyone shed any light on it as I have no idea how it is used etc? How much is it worth? I am looking to sell it to free up some room. My email is bodsterbug aol.com. Here are a few pics"
Update via Steve in the comments: "Check out this youtube video featuring the Alpha Syntauri (spelled there Alpha Centauri, like the constellation). The sound quality is somewhat muffled." Video below.

"Soundtrack by Mark Murdock for THE MEIRE CHRONICLES UFO documentary film featuring Apple 2 and Alpha Centauri [alphaSyntauri] Mountain Music- the first digital music software introduced in 1981 performed by Mark Murdock and assisted by Joe Berger on a very low budget" Update via Deadpan110 in the comments: "Quote: At the same time synthesizers were becoming less and less analog. Digital sequencers and digital keyboards were the norm, and digital oscillators offered better stability than the analog type. A microprocessor of the day could be programmed to produce 16 voices of somewhat limited tone colors, and this cold be build on a circuit board that would fit into a slot on an Apple II. These boards were mostly built by hobbyists, but commercial versions were sold by companies like Mountain Hardware. The Alpha Centauri was based on such a board and also included a piano style keyboard and sequencing software. Also: There must have been over a thousand hybrid systems built between 1978 and 1984. Most of these were home made. Found on: Short History of Computer Music - Part II." Update via Laurie Spiegel: "To elucidate this mysterious antiquity somewhat: The alphaSyntauri (note: not "C...entauri") "The Origin Syn" (as our promo buttons said): http://www.purplenote.com/syntauri/" link to proximaSyntauri website.
"Very similar to the Sk20 just lacks some of the SK20'S features but soundwise pretty much identical . Great for string and organ sounds. Has a lovely ensemble effect. Comparable in sound to Roland RS202 synth."

"Description from the Mini Organ Website: 'Incredible Machine. Far ahead of its time - a mini sequencer with endless possibilites. Kind of a ROLAND TB-303 but much cooler & cheaper - still cheaper... The coloured buttons can be used to change the melody and rhythm. Each color has a different tune. You can also change the speed and pitch of the sequence with 2 sliders. This was also released by Palitoy in the UK.'
This comes Mint in the Original Box. Works perfectly. I will even throw in the C batteries. Box is not in the best shape, but its complete with directions."
