“Up for your consideration is this vintage Triadex Muse synthesizer and amplifier set.
They’re both “New Unused In The Box” and below you’ll find a demo video along with the photos.
We don’t have the patch cords that connect the Muse to the amplifier to test the operation of the amplifier,
so the amp wasn’t tested and is being sold along with the Muse in “as is” condition.

These rarely seen Muses seem to show up here in the Boston area more frequently than anywhere else in the country, due to their close proximity to
MIT and Brookline, MA. where they were manufactured.
The Muse is probably the rarest, strangest, best-looking vintage synth ever mass-produced; it cost $300 in its and looks like something
Dieter Rams would have designed for Braun in the sixties.

The Muse had, in its day, impeccable geek credentials; It 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.
Ten years later, Edward Fredkin would create the Fredkin Prize, to be awarded to the creators of the first computer to win the
World Chess Championship.
He paid out the award to IBM’s Deep Blue in 1997.

The Triadex Muse is the first digital musical instrument and was produced in 1972.
It is an algorithmic music generator: it uses digital logic circuits to produce a sequence of notes based on the settings of various parameters.
Since the Muse was designed as a composition tool, not a synthesizer, there is no control over the timbre of the sound;
rather, the front panel controls affect the melodies that are generated.
The exact logic behind the composition engine is rather technical, and not exactly intuitive, but the manual explains it all in depth.
The four small sliders in the lower-left 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 tempo clock can be slaved to that of another Muse, allowing for multi-part compositions.

The cosmetic condition of the units are in excellent condition as they’ve only been taken out for this demonstration.
The original instruction manual, papers, & tags are included with the Muse and amplifier.” Click here to visit listing on eBay

“Triadex Muse, rare algorithmic sequencer and tone generator. Produces a million possibilities for melodies by making various selections with the control sliders. Fun and easy to use.

This unit is fully functioning, however one LED is not lighting in the matrix (which has no effect on the sequences or sound). Wood base is slightly warped, and there is some wear to the finish on one edge of the wood as seen in the photos. ” Click here to visit listing on eBay

“…… This auction is for a rare, investment quality, 1970s Triadex Muse Synthesizer along with its original Light Show Module and Amplifier Speaker Module! Unfortunately, we are missing the original wire to connect the speaker to the other two units however, we did hook up the light show to the synthesizer and will be posting a video of these units working down at the bottom of this auction. (I apologize for my lack of knowledge when it comes to making this thing sound good…I flipped as many switched and levers as I could, to show you what it does.) We do not have the equipment or knowledge to fully test this unit, but we guarantee that all of the internal parts are original and complete! (We did find a fantastic video of all three of these units up and running on Youtube which you can find by searching “Triadex Muse Light Show”.) All three units measure 11” by 11” by 13 ½” and, as you can see in our photographs, they are all in excellent cosmetic condition! There are a couple of minor rubs and light scratches but all of the knobs and switches are original and function properly and the wiring is original.” Click here to visit listing on eBay

“This auction is for an extremely rare Muse digital sequencer synthesizer made by the Triadex Corporation in 1972. The Muse was created by MIT professors Marvin Minsky and Edward Fredkin and is considered to be one of the first electronic musical instruments. The Muse uses a series of 14 sliders to control tempo, pitch, etc., and can create trillions of possible musical variations. This auction also includes a Triadex light show that links with The Muse . The Muse is extremely rare, less than 300 were believed to have been made, and only 50 of the light show! This unit is in very good working condition, the bottom wood panel of The Muse is warped and has a shrinkage crack. There is also some slight warping to the wood on the light show and a small crack. There is some light wear and few spots to the faceplate. The Muse and light show both appear to be in good working order, the sliders move smoothly, switches are good, and it sounds great. This is an incredibly rare piece and I can’t begin to detail it’s history here. ” Click here to visit listing on eBay

“It looks like it’s missing a couple of switches and will need a small amount of work to be fully functional. You will need to source the parts which is the hardest part since there were less than 300 made, but if you already have one and need parts, this could be your ticket!

Luckily, you can play with this bad boy as is, as shown in my youtube video I put up. Look up: Super Rare Triadex Muse Digital Synth For Sale to see the unit in action.”

“This auction is for an used Ultra rare early Syntesizer Triadex model MUSE

From the estate of a local Audio collector

The Muse was designed by two famed MIT professors, Marvin Minsky and Edward Fredkin

The item need a external clean to look excellent again, this was not clean, to avoid any damage by using improper cleaning.
Two knobs are missing,they are here in some place but are easy to replace and if you want i could replace it before sending

Turn ON , but not other test was made , this item may need lubrications and/or some work .” Click here to visit listing on eBay

” This item was purchased as a weekend project, but I’ve no time to finish the repairs. It powers up, but needs servicing. I don’t have schematics for the unit, and I haven’t been able to specifically diagnose the issue(s). It’s not currently making sound, but other than a missing speaker and a volume selector switch, it’s believed to have all the necessary parts.

If you’ve got a multimeter and the necessary time to evaluate the board, then this is your chance to have a partially-working unit at about 1/3 the cost of a working unit. I used and later sold another Muse in 2003, which sold for $1200. This unit has no back panel and the bracketing of the unit is different from other models. I do not know if this was an early production or a later model.” Link

“TRIADEX MUSE SYNTHESIZER NOT WORKING

SCHEMATICS INCLUDED

FREE SHIPPING

You are bidding on the incredibly rare Muse synthesizer manufactured by Triadex of Watertown, MA. The item does not work properly, but does power up. The internal speaker appears to be blown, and has partially separated from the inner chassis. This is a fairly generic 3″ 8 ohm speaker that should be easy to locate. However, the external speaker connection reveals that the oscillator is working, but just delivers a single tone. The sequencer lights appear to be working, and will change configuration to match the position of the control sliders. The top section of green gel filter has slipped down between the front panel and the circuit board, so just bare white bulbs are visible on the very top section of lights. All of the lights appear to be working properly. The volume slider handle is broken off below the front panel. It is operable, and will control the volume. Schematics will be provided to the winning bidder. For someone with the technical ability to troubleshoot logic and analog audio circuitry to the component level could repair this item.” Click here to visit listing on eBay

“This is the famous Triadex Muse, regarded as the first digital sequencer /synthesizer. You can find numerous interesting writeups on the Internet. In a nutshell, the sequencer is unique in its approach leading to long, patterns that are often serendipitous, a useful aid to composition.

This unit is fully functional, completely cleaned, inside and out. the sliders have been cleaned and lubricated. The front panel is in excellent condition, you may note a small ding in the photos.
All the colored sequencer lights work too as it steps though the sequences (fun to watch too)

The wood cabinet is in good condition, no major issues, a little warping on the bottom piece, a few minor scratches on the wood that disappear with fresh furniture polish. this is over 40 years old but a great piece to use, or simply add to your collection. ” Click here to visit listing on eBay

“Muse Triadex Synth. Very rare, this one is number 51 out of less than 300 made, the exact number is unknown. It was made in MIT, Massachusetts Institution of Technology, and is said to be one of the first digital synthesizer/sequencer. Works 100%, just missing 1 button as shown, but does not affect the functionality. It’s in excellent shape for its age, and you probably will not find many for sale, but from what I’ve seen, they usually go for around $2,000 in similar condition. Original manual is in good shape, and has some notes in it about songs and whatnot. ” Auction ended. Click here to browse on eBay.

The circa 1972 Triadex Muse was the first digital musical sequencer based synthesizer composition tool and deterministic algorithmic event generator
It used early digital integrated logic circuits to generate an audio output that produces a sequence of notes based on the settings of various parameters.
Only a few hundred Muses were produced and they were never made available in stores. ” Auction ended. Click here to browse on eBay.

“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.

“Appears to be in very good WORKING Condition. The Built in speaker Sound is good. Start ON-OFF, auto hold and step, the tempo, volume, pitch, fine pitch sliders all work for sure. The other 4 “interval” & 4 “theme” program sliders seem to “click” as they should to change the pattern etc. The vertical lights on the right seem to function as designed. I did not test the “rest normal” & “external normal” speaker switchs or any the jacks on the underside.

Cleaning the sliders to sliders more smoothly is up to you, I’m not messing with them as they seem to work ok. (I do not have a manual)

Cool Original circuit-bent type sound manipulator.

This unit is sold as is, but guaranteed not to be DOA.” Auction ended. Click here to browse on eBay.

“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 (light show refers to the Muse’s built-in lights that run up and down with the musical beats).” Auction ended. Click here to browse on eBay.
