Check it out: 1980 Alpha Syntauri Computer Music System | Synth History

video upload by MR TUNA Music

"My friends, I present to you the complete 'alphaSyntauri' (Alpha Syntauri) Computer Music System circa 1980. I finally got it all set up and (mostly) functioning after buying this from a nice old lady in town. The old Apple II clone had a shot power supply so I found a new one and we're off to the races!!

This is a not-so-quick demo of some of the features I was able to coax into functioning, and a few sounds that came standard with this cool vintage computer music system."

Looks new. Esoteric piece of synthesizer kit. Just cool that things like this exist for those that might need it.

"Alphasyntauri synthesizer interface card for Apple II
This is just the (hard to get) interface between the keyboard and the apple II.

For a full working Alphasyntauri you also need:
Mountain Hardware Music System (MCMS) board set (2 boards)
Alpha Plus software (at minimum)"

Audio Damage Phosphor 2 - alphaSyntauri Based iPad Synth Now Available

Now available on iTunes.

You can find two video demos of Audio Damage's Phosphor 2 just posted here.

Details follow:

"Phosphor is an unique instrument modeled on the alphaSyntauri, a vintage digital additive synth from the early 80s. The original alphaSyntauri required an Apple //e to operate, but we've gone ahead and eliminated the middle-man, and now you can have this classic digital synth in your iOS device, no 5.25" floppy drive necessary!

Featuring two additive oscillators (with the original 16 partial complement of the alphaSyntauri, or optionally with 32 or 64 partials), each with its own amp envelope, Phosphor's topology closely follows the alphaSyntauri, while adding many modern features such as full velocity control, a much more extensive modulation routing system, tempo synced LFOs, a pair of delays, and two monophonic modes. The noise and oscillators are able to work in the original alphaSyntauri "low-resolution" modes, or can be run in modern high-resolutions. Phosphor can accurately model the original sounds of the alphaSyntauri, yet still provide new paths for sonic exploration.

Features

• Two complete oscillator/envelope sections modeled on the original topology of the alphaSyntauri.

• Each set of partials can run in "lo-fi" mode, emulating the gritty digital voicing of original, or in a modern mode for alias-free sines.

• The noise can be either "lo-fi" digital shift-register noise per the original, or modern white noise.

• Two complete delay sections with LP/HP filtering and cross-feedback.

• Two tempo-syncable LFOs with multiple modulation destinations.

• A large complement of presets included that show off the extensive sound generating capabilities of Phosphor, including some famous alphaSyntauri presets directly ported from the original.

• XML preset system, with copy-to-clipboard, for sharing presets in forums and with your friends.

• AudioUnits V3 version for use in all AUv3 hosts, like AudioBus 3, AUM, BeatMaker 3, Cubasis 2, GarageBand, etc.

• Standalone version (with full single-panel UI) with Inter-App Audio and BlueTooth MIDI capability.

• iPhone version coming soon!"

"ESTATE Find in Excellent Cosmetic Condition - Untested but previously working and rarely used when put into dry storage with the original packaging. (see pics)

These Syntauri Synths are very usable, extremely desirable and incredibly rare, but almost never complete. This is a tremendous opportunity to buy one complete and in amazing condition.

KEYBOARD - Excellent Cosmetic Condition with the Original Box! AND YES, the mega rare to find foot pedal too...

SOFTWARE - Complete, including disks, original operations manuals & folder. Even includes the purchase receipt for $1,795 (without the computer) in the 1980s.

INTERFACE CARDS - Mountain Computer System Sound Card and Syntauri Interface hardware is included with original packaging.

MISC - Amazing find. Included is an original promotional 7" flexi-record with Syntauri music and sounds. Never removed from the promotional sleeve.

As mentioned above, the system is untested, but it is a 1-owner item that was stored away in excellent condition. You'll need a 1980s Apple 2 II (Approx $400-600) to run the software and use the synth.

BBC Micro Computer. Spotted an Alpha Syntauri in the intro as well.

"Episode 7 (Of 10). Broadcasted in BBC-2, 21 February 1983

Making the Most of the Micro was a TV series broadcast in 1983 as part of the BBC's Computer Literacy Project. It followed the earlier series The Computer Programme. Unlike its predecessor, Making the Most of the Micro delved somewhat deeper into the technicalities and uses that microcomputers could be put to, once again mainly using the BBC Micro in the studio for demonstration purposes. The series was followed by Micro Live.

List of Episodes:

1. The Versatile Machine (10 January 1983)

Puremagnetik alphaSynth - Alpha Syntauri Sample Set

"A library of old-school computer sounds captured from a late 1970s 8-bit Apple ][ with an Alpha Syntauri music system."

Available at Puremagnetik

This set comes from Chris Randall of Analog Industries & Audio Damage, with more to follow: "It is a heavily re-tooled and much improved version of the sample set I used to have here that I made from the alphaSyntauri. They are much, much better at that sort of thing than I, what with doing it for a living and all, and the alphaSynth set is available in several formats, including Live Rack, Kontakt, and ESX Universal.

I've made a bunch of other samples for them with various pieces of Apple ][ based kit, and you can watch out for those in the future."

alphaSyntauri Demo 1

alphaSyntauri Demo 1 by RossT
"Improvisation on an alphaSyntauri Apple }{ system. Recorded and edited in Logic. The preset on the alphaSyntauri was stereo, processed through two digital delays and the channels were separated in the editing process. The deep bass/kick sound is from a soft-synth in logic."

Audio Damage Phosphor

via Analog Industries

"What it is: a two-oscillator 16-voice polysynth loosely based upon the topology of the alphaSyntauri additive synthesis add-on for the Apple ][+ and //e. We've added some modern features like the delays and mod routing, mono modes, and a "clean" setting for the sine waves and noise, in order to extend the capabilities of the synth past its original limits. But this plug is mainly designed for recreating the alphaSyntauri, and at that, it excels."

Update: video of the alphaSyntauri:

Vintage Sound Systems - AlphaSyntauri

"The Alpha Syntauri was the flagship digital synthesizer produced by the Syntauri corporation in 1980. This short clip gives an overview of a unit I originally purchased in 1982, serial #A003184. The synthesis hardware engine is provided by the Mountain Computer synthesizer board set that mounted into bus slots within the Apple II. They supported 8 channels of 8-bit stereo audio. AlphaPlus is Syntauri's software application demonstrated here."

via bodsterbug in the comments of this post.

"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.


UFO from the PLEIADES Mark Murdock SOUNDTRACK
YouTube via musicproductionnotes
"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."
