TRIADEX Muse, Light show and Amplifier module.... from outer space _-_-_

YouTube via scienceforce

"Extremly rare Triadex Muse, Triadex Amplifier and Triadex Light show. A complete collection of a trio set from '72 still with the original boxes, manuals, cards and...the old warranty papers ;-) ALL is perfect working and lighting.
The Triadex Muse is the first digital musical instrument and was produced in 1972. It was designed by Edward Fredkin and Marvin Minsky, the creator of the alien "MONOLITH" in 2001 SPACE ODYSSEY, friend & collaborator of Stanley Kubrick.

Marvin Minsky has made many contributions to AI, cognitive psychology, mathematics, computational linguistics, robotics, and optics. In recent years he has worked chiefly on imparting to machines the human capacity for commonsense reasoning. His conception of human intellectual structure and function is presented in The Society of Mind (1987), which is also the title of the course he teaches at MIT.

The Triadex Muse it's an algorithmic music generator: it uses digital logic circuits to produce a sequence of notes based on the settings of various parameters. It has four small sliders that control Volume, Tempo, Pitch, and Fine Pitch. It is not known how many were made, but they are considered extremely rare.

For years, the Muse was a featured exhibit at the Museum of Science, Boston. The signage explained the device's algorithmic (and deterministic) approach to the creation of its seemingly-random music. Far from being random, its preset "song" played continuously -- and was even given a name, "Museum Musings," by the staff."

Update via Minsky in the comments:
"Thanks! Really nice article and explanations.

No, I didn't invent the Kubrick-Clarke monolith. I only made some suggestions about the appearance of some of the movie's intelligent hardware. (Early versions of the computer modules were rather fancy -- but we simplified them.)

- Marvin Minsky"

Triadex Muse Vintage Music Synth MIT Digital Instrument

"The Triadex Muse is a sequencer based synthesizer. It was first produced in 1972. It was a deterministic event generator that used early digital integrated circuits to generate an audio output that could sound very musical. In this auction you will receive both the Triadex muse and the accompanying amplifier. They both have the original boxes.

Update: Tom of Music Thing noticed that the details for the auction copied below are taken from his Triadex Muse post on Engadget from way back. Check it out; it's a direct copy word for word. Eeentwesting...

Cikira sent me a link to this auction. Below are all three shots and details pulled from the auction. I've never seen one with covers before. BTW, you might also remember Cikira's Aibo playing a Muse in this post. Thanks Cikira!

Details (not sure about that first sentence):
"It's probably the rarest, strangest, best-looking vintage synth ever mass-produced. At a time when Moog and ARP were selling synths the size of wardrobes that looked like lab equipment and cost tens of thousands of dollars, the Muse was the size of a typewriter. It cost $300 and looked like something Dieter Rams would have designed for Braun in the sixties.It had impeccable geek credentials. It was designed by two MIT professors, Marvin Minsky and Edward Fredkin. So what was the Muse? Well, not really a synth. It was a digital sequencer, which played melodic-sounding bleepy music through the internal speaker, based on a baffling set of algorithms. As you moved the sliders, the algorithms changed, and the music changed.The Muse even had an even rarer accessory, the ‘Light Show’, which flashed coloured lights in time to the music. Inevitably, the Muse was a commercial disaster. Only 280 units were ever manufactured.In 2004 1 of these received a bid of $1799.00 on Ebay. AOL search (TRIADEX MUSE) what I have for sale is 3 individual pcs., THE MUSE, THE LIGHT ORGAN and THE EXTERIOR AMPLIFIER, all 3 pieces have only been out of their boxes to be photographed, are these the only ones in this incredible condition? all cords are still wrapped up and all paperwork is still in the boxes, heres a chance to own the best examples of these RARE music boxes from TRIADEX. I believe this is a modest starting price for something of this caliber.Any questions please e-mail me.Buyer to pay shipping & handling USPS.Payment must be received within 10 days or item will be re-listed." This one started at $1600 US.

It is digital. More on the Muse here.

"In this auction you will receive both the Triadex muse and the accompanying amplifier. They are both "MIB’ as seen in the pictures. One of the boxes got a little wet as seen in the pictures. This in no way affected the contents of the box as the amplifier was wrapped in plastic. For some reason these "rare" Muses seem to show up here in the Boston area more frequently than anywhere else in the country. This may be due to their close proximity to MIT and Brookline, MA. where they were manufactured. Even though they were ahead of their time and somewhat of a technical marvel they ended up being somewhat of a commercial flop. This may explain why they never crept far beyond their backyard from which they were created. The cosmetic condition of the units are in excellent condition as seen in the pictures. The original instruction manual and tags are included with the Muse and not the amplifier.

We have included a 20 second movie [at end of post] in the listing (located just below the pics of the receiver) to give you a tease as to how this Muse works and sounds. The hand you see in the video in no way represents the Muses current owner and is merely a prop "hired hand" to assist in the demonstration. The Muse in the movie is the actual Muse that you will receive if you are the winner of this action. We do not have the patch cords that go from the Muse to the amplifier to test the operation of the amplifier. So the amplifier was not tested and is being sold along with the Muse in "as is" condition. This is truly a rare opportunity to own both the Muse and the amplifier. We have started the auction at what we believe, is a reasonable starting price. This would make a wonderful Christmas present for yourself or the "techno-geek" in your life. The Muse had an even rarer accessory, the "Light Show", which flashed colored lights in time to the music. In all of my travels I have only seen one of these. It was a very simple circuit and was constructed of, believe it or not, G.E. colored Christmas lights.

Triadex Muse - 1972 Vintage Digital Music Sequencer

via this auction

"History
The Triadex Muse is the first digital musical composition instrument. It is a sequencer based tone synthesizer and it was first produced in 1972. Essentially, the Muse is a deterministic algorithmic event generator that uses early digital integrated logic circuits to generate an audio output that produces a sequence of notes based on the settings of various parameters. In the 1970's when most synthesized music makers were huge and cost thousands, the Triadex Muse was a reasonably sized tabletop model and cost $300. Only a few hundred (we think around 300) were produced and they were never made available in stores. The Muse was designed by two famed MIT professors, Marvin Minsky and Edward Fredkin. At the time, Minsky was moonlighting on the movie set of '2001 A Space Odyssey', teaching Stanley Kubrick about Artificial Intelligence as he created Hal. Isaac Asimov described Minsky as one of only two people he would admit were more intelligent than he was, the other being Carl Sagan. Ed Fredkin was an early pioneer of digital physics. In 1980, Carnegie Mellon U. created the Fredkin Prize, to be awarded to the creators of the first computer to win the World Chess Championship. The Muse was designed to replace a radio - why listen to old music when this neat-o box can make new music?

How it Works
The front panel sliders, which control the melodies that are generated, allow for the possibility of 14 trillion musical note combinations. The four small sliders in the lower-left control Volume, Tempo, Pitch, and Fine Pitch. The switches to either side of the sliders are used to start and stop the sequence, or to step through it note-by-note. Of the eight larger sliders on the right, four control the musical intervals used (labeled A, B, C, and D), and four control the theme (labeled W, X, Y, and Z). There is also a "Rest" toggle switch at the lower right which acts as a "lowest note".

Details
The musical computer is housed in a sleek mid-century modern wedge shaped finished wood and brushed aluminum case. Located at the upper left of the unit panel is the internal speaker.
It measures 10 inches high x 11 inches deep x 13-1/2 inches wide.
The cosmetic condition of this Muse is good, but it has seen some use and it is almost 40 years old. It is missing the on/off switch, however the switch is in the ON position, so when you plug it in, it works. There is a scratch in the brushed aluminum above the tempo slider, and the wood has warped a little bit and has some surface scratching here and there around the case. The electrical cord has also been cut at some point, not all the way through but enough to expose the copper inside. It has been repaired with some electrical tape and hasn't had any issues since.

"This is an incredible opportunity to purchase a rare piece of history.

According to synthmuseum.com, "This unique machine [Triadex Muse] is regarded by some as the first digital musical instrument. Designed by Edward Fredkin and Marvin Minsky at MIT, the Muse is an algorithmic music generator."

Engadget writes "[The Triadex Muse] had impeccable geek credentials. It was designed by two MIT professors, Marvin Minsky and Edward Fredkin. At the time, Minsky was moonlighting on the set of 2001 A Space Odyssey, teaching Stanley Kubrick about Artificial Intelligence as he created Hal."

"The Muse even had an even rarer accessory, the Light Show, which flashed coloured lights in time to the music... Only 280 units were ever manufactured. Unlike vintage analog synths, a Muse won't generate a fat bassline for a hip hop record, but they are very collectable."

This particular Tridex Muse is in good condition. There is a small scuff mark on the stainless steel front near the Muse logo. A control toggle switch is imperfect and loose, and will not stay in the 'down' position. Besides these issues, the wood is in superb condition, as are the stainless steel face and sides. The sound works perfectly as does the light show.

"From the hometown in which it was designed, we are offering a beautifully preserved TRIADEX MUSE sythesizer. A very historic item, as the sequencer in the MUSE is considered the very first digital instrument ever!, designed by two engineers from MIT, Marvin Minsky and Edward Friedkin. An extremely rare piece only about 240 of these were ever made, and not typically available for commercial sale. This piece is in excellent working condition. The woodwork is also in excellent shape. As you can see from the photos, the faceplate, writing and original lights have all been very well preserved also. The unit also comes with a detailed manual. The synth has a great sound, which can be monitored both through a built-in speaker, as well as an external speaker that can be easily connected through the back. The sequencer for this item is very unique and unusual. Controlled by sliders in the front of the unit, the MUSE was designed to have the capacity to actually select notes and invent themes, as an early experiment in artificial intelligence. By adjusting the sliders, one controls how these themes develop. A very interesting compositional tool! Great for anyone with an interest in electronic music. What more, the synth has a classic, haunting and musical sound. -the Smithsonian Institute selected the MUSE for display in their musical instrument show\ -among other musicians, film composer Tony Lusis featured the MUSE in the theme for the movie "The Call of the Spirit." -featured in the TV show "The Wonderful World of Popular Science," in which the MUSE is used to compose a two-part invention. A very special piece for any synth enthusiast, or electronic composer."

Triadex Muse - (Link to VSTi of Muse)

It's funny how some things come in waves. I was reading the new issue of Future Music magazine and the "Back to the Future" feature item is the Triadex Muse. It's a rare and interesting piece of gear known as the first digital musical instrument. It came out in 1971. It's basically a sequencer with built in speakers and tone module. I thought how cool it would be if you could midi it up and use it to control other synths. Well, I catch up on email and there's a thread from Cikira on AH on just that. The owner of the Muse below converts the output to MIDI. Also, there is a software simulation of the Muse that transmits midi. Pretty cool.

From the email thread, "We agreed that a good word for these things is "inscrutable". It's tough to figure out how the sliders interrelate, but sure enough you get repeating, evolving patterns, and as it plays you start to identify recurring motifs. Its internal speaker puts out a decent level, and it does a little light show that reflects what it's doing, only it doesn't really help you figure it out. "

1972 Triadex The Muse– World’s First Digital Instrument

via this auction

"The Triadex Muse is the first digital musical instrument ever made. The Muse is a music composer machine or digital synthesizer and melody composer, involving early logic modules in a unique circuit that allows the
 possibility of 14 trillion musical note combinations.

It was made in 1972 by Triadex Inc., Brookline, Mass. It was designed by Edward Fredkin and Marvin Minsky at MIT. The first Muse was designed by MIT graduates Edward Fredkin and Marvin Minsky in the late 1960’s. Minsky was on the set of “2001 A Space Odyssey”, and taught Stanley Kubrick about Artificial Intelligence as he created Hal.

The Muse is an algorithmic music generator that uses digital logic circuits to produce a sequence of notes (through a 4-inch built-in speaker or external speaker) based on the settings of various controls on the front panel: four small sliders that control Volume, Tempo, Pitch, and Fine Pitch. The switches to either side are used to start and stop the sequence, or to step through it note-by-note. Of the eight larger sliders on the right, four control the musical intervals used (labeled A, B, C, and D), and four control the theme (labeled W, X, Y, and Z). A rest can be substituted for the lowest note by flipping a toggle switch.

The exact logic behind the composition engine is rather technical, and not exactly intuitive. The tempo clock can be slaved to that of another Muse, allowing for multi-part compositions. These connections are on the underside (see photo).

It is not known for certain how many were made, but they are considered extremely rare. Estimate stated by Tom Whitwell, of the now defunct blog spot, Music Thing, was that only 280 were made.

The Muse is the subject of U. S. Patent 3610801. For years, the Muse was a featured exhibit at the Museum of Science, Boston. The signage explained the device's algorithmic (and deterministic) approach to the creation of its seemingly-random music. Far from being random, its preset "song" played continuously -- and was even given a name, "Museum Musings," by the staff."
