MATRIXSYNTH

The Impossibilitron

YouTube via x9spaceman — January 19, 2008 — "Yes, I have too much time on my hands.
Don't ask why I built this, I really don't know.

I got this box at a yard sale for 5 bucks, and stuck all this stuff & parts all over it.

6 Guitar strings, a bass string, a ship whistle, a jaw harp, 2 Morse code tappers, and a big knob & phone rotary that do nothing."

MARDIS ORAC speech synth / communication aid

via this auction

"This is for a MARDIS ORAC speech synth / communications aid. I think it was designed as a tool for disabled people to communicate by pressing buttons in a stephen hawkins kind of manner, and i do know that these things are obscenely expensive to buy, but i have no idea if this one is working properly or even at all. This could possibly be down to the fact that i have no idea how it should operate but all i know is that you plug in an external 9v power supply, one of the keyboard LED's lights up and some blocks appear on the screen. Other than that its a mystery to me, maybe you need some kind of overlay in the front before it'll do anything, or possibly you need to charge an internal bettery.

Theres a lot more information on this thing at the Mardis website here http://www.lancs.ac.uk/depts/mardis/products/orac.html"

circuit bent kawai k1m vector synth by spunkytoofers

via this auction

"-module in excellent cosmetic and functional conditon

-all connectors and moving parts in audio path cleaned and relubricated

-internal battery has been replaced with a battery clip and new battery. the clip allows easy replacement of internal lithium battery by the user. battery should last 10-15 years.

-1 getlofi precision oscillator to control sample rate via added fluted tophat knob

-1 switch selects precision oscillator or original clock

-1/4" trs jack for expression pedals or midi control via spunkytoofers midi modules

-vintage red pilot lens with chrome base

-24 point banana jack patchbay. all bends have been carefully selected for stability and responsiveness to sound design

-8 point jack bay for switching with 4 switches. for on/off of bends. all points are color coded for ease of use

-8 stackable banana cords provided

-pdf manual, bend diagram, and k1m sound banks emailed to winner

-power supply provided for those in north american countries. those in other countries will need to supply their own 12 volt, 500ma adapter negative tip

the kawai k1m is a hybrid synthesizer that relies on pcm sampling and additive synthesis based on harmonics. it's sound can be morphed via the vector joystick. this blend of synthesis along with circuit bending makes for a truly special and unique synthesizer that would be impossible to achieve otherwise.

under midi you have multi-timbral control, aftertouch, modulation, pitchbend, split points and other features that make this a musical instrument. this puts this in a league beyond circuit bent toys. truly a circuit bent musical instrument.

all bends have been carefully selected and are completely stable.

in the video demo below you'll notice i've setup all the bends under midi. the k1m's bends are open ended and can be controlled under midi with spunkytoofers midi modules. all instruments by spunkytoofers have been redesigned to be a modular system which can be controlled or intermodulated with one another. the k1m gives you complete manual, analog controls over the bends but all instruments are designed to be controlled under midi. on the k1m the bends can be modulated by sequencing or triggering over midi and the sample rate control can be modulated either by footcontroller or outputs from a spunkytoofers midi module freely assignable from midi cc's, notes, etc.

along with the instruments ability to be fully controlled under a midi modular system all instruments are also supported. i will back my work for free warranty work and will assist customers with any instrument they purchase from me as they are instruments i work with in my music performance and sound programming.

the video below demonstrates very simple setup under midi. the pads on a akai keyboard controller are used to toggle bends on and off under midi. this would be the same as manual control over bends except that it's easier for me to trigger the bends all from one controller. the banana cords are routed from spunkytoofers midi matrix module to the k1m's banana jacks. the midi module is also sending potentiometer control over midi to the k1m at the 1/4" trs jack with a sequence from the dave smith evolver and via midi mod wheel on the keyboard for more variation. please note i choose to modulate the module under 10k control. this can accept any value foot controller or potentiometer value beyond 10k and is capable of a much larger range of control. no effects are applied and the k1m is recorded direct from the module's output."

EMS VCS 3 studio synthesizer

via this auction

"A very nice EMS VCS3 studio modular synthesizer in fully working condition !! cosmetics just some marks on the wood case (see pictures) otherwise perfect ! all patchpins are presented.

this is a piece of history synthesizers , made in the UK in small examples ,to create a sound you have to use the patch system , you have to know how to work with it ! very complex sound creation possible and with the joystick to vector a way thru the sound field , this one has a update like sync OSC's and the filter selecter 24 db/18 db ! 220 volts !!"

Vintage Octave Plateau Voyetra Eight 08

via this auction

"Here's a rare chance to grab one of the best polyphonic 8 voices midi analog synth on the planet: A Vintage synthesiser Octave plateau Voyetra 8 rev 4.

I place it in the same league as a Jupiter 8, except that the V8 is midi, doesn't take so much space and is much harder to source.

Less than 800 ever built, many of them are malfunctioning ( early revision without the black fan at the back never worked properly) and not many were upgraded to the latest revision 4 ( barely a few hundreds).

Rev4 offers more midi capabilities like control over velocity, modwheel and pitchbend.

Rev 4 is also the only revision that you can control using the midi editor Midiquest Xl or via the V8 app for the Mackie controller C4 .

Voyetra-8 - Wikipedia, the free encyclopedia

It's been fully serviced 3 years ago by Peter Lanzillotta . This baby tunes & works perfectly but will have Peter look at it again at my expense when it's sold for your peace of mind. The waiting time won't be more than 1 week after i receive your payment. Peter and I live in the same city, i know him well as he has serviced all 7 Voyetra's i've owned in my life.

I didn't list the VKP5 in this auction but it's available. If you're interested in the keyboard as well let me know and we'll work out a deal."

Sold For: US $5,300.00

Welson Syntex Ultra Rarer analoger Italo Synthesizer

via this auction

(English translation below)
"Biete hier an , einen Welson Synthesizer Typ Syntex .

Der Syntex funktioniert voll und lässt sich spielen aber in Anbetracht des Alters krachen die Schalter und knistern die Potis ,...wie halt von den meißten italo Synthis dieser Zeit gewohnt :-))

Natürlich hat er auch altersbedingte Gebrauchsspuren

Ungewöhnlich guter Filter , eindeutig einer der besten , diskret aufgebauten , in einem Italo mono Synth !

Total verrückte Sample und Hold Funktion :-) , volle ADSR Hüllkurve , LFO Modulation auf die 2 Osc , Filter und VCA

Wird mit Schaltplan als pdf geliefert

Zu sehen auf youtube in einem Grobschnitt - anywhere Video aus den 70'gern ,.........verdammt lang her :-(

Am liebsten Abholung , da dieser Synth doch sehr empfindlich ist ....Versand aber auf eigenes Risiko auch möglich

Ich hatte drei von denen .......hatten sich die letzten 20Jahre hier so angesammelt :-))

Hatte letztens schon mal einen hier versteigert , dies ist der 2.

Den letzten werde ich behalten

Und wie immer ..........

Leider keine Garantie , da Privatverkauf aus Sammlung

Da ich selbst Techniker bin , garantiere ich aber das der Syntex voll funktioniert

Up for sale here we have a full working Welson Syntex synthesizer .

Due its age = noisy slider and switches and signs of usage....but full working"

via Florian who provided this translation:

"I offer a Welson synthesizer of type Syntex. The Syntex is completely functional and can be played, but regarding its age some switches and potentiometers crackle - as most of the italian synths from this age.

Also there are optical traces of usage - corresponding to its age.

Exceptional good filter, definitely one of the best discrete built filters in an italian synth.

Totally crazy Sample and Hold function ;-), full ADSR envelope, LFO modulation on both of the two Oscillators, VCF and VCA.

Schematics will be delivered as pdf.

You can see this synth on youtube in a Grobschnitt - anyware video [remark: Grobschnitt is a mid to late seventies Krautrockband] ... damn' long ago.

I'd favour local pickup, since this synth is quite delicate ... shipping is possible but definitely on the risk of the buyer.

I had three of those ... they accumulated here somehow ;-))
Recently I sold one here. This one is the second I am selling. The last one I will keep.

As usual...
No Warrenty, since this is a private sale [remark: this is a legally required disclaimer in the EU]

Since my profession is technician I can confirm that the Syntex works completely."
