"Synthesizer Specifications:

* Voltage Controlled Oscillators - they go Low Frequency too!
* Featuring Saw/Square (PW/PWM)/Triangular and Sine waveforms.
* Frequency control of the Oscillators is by Octave Switching (5 Octaves) a Course Frequency Control slider and by a Fine Frequency Control slider and by +-1V/Octave, ie positive or negative polarity so that you can 'play the keyboard backwards' should you want to.
* There is a four input CV mixer as well as a Voltage Controlled Pulse width input.
* Prepatched into the oscillators are the two LFO's, as is Oscillator 2 to Oscillators 1 and 3. (Most of this synth is pre-patched in a very similar way to the 2600 synth. There is Oscillator Synch between Oscillators 1 and 2, Oscillator 3 features a 'Stability' potentiometer to cause drift inherant of older analogue synths, circa 1970, this control is very subtle, but fattens the sounds up greatly!)
* 2 LFOs with separate Rate controls as well as a Master Rate control, the Dual VC LFO's also include Sample and Hold and Lag/Slew Processors.
* 2 Voltage Controlled Filters - The main filter is of the 24dB/Octave
Self-Oscillating Transistor Ladder type and the second, 'Utility' Filter is a 12dB/Octave State Variable type that features Low pass, High Pass, Band Pass and Notch responses.
* The 24db/Octave Voltage Controlled Filter/Oscillator features a five input Audio Mixer and a five input CV mixer!

Again many sources are pre-patched for both Audio and CV. As with the Oscillators, Filter Control can be both positive and negative in it's polarity! The Filter features Both Course and Fine tuning sliders as well as a logarythmic Resonance slider that brings the Filter to oscillating a pure Sine wave!"

"This really an electrical and mechanical wonder. First, it has a motor which moves across a field of contacts at a speed set by the tempo control. there are a few dozen neon lamps which trigger to (I guess) give that percussive sound. This is quite a light show - It might be fun to mod this to make these visible during use."

Update via Loscha in the comments: "One of the finest, most innovative things Yamaha ever made.
It's a Tx81z with a basic effects unit, a sequencer, and a clock. Effects have a great gated reverse reverb. Think the "Silent Shout" album by The Knife (a few tracks have a horn-type sound that fades in with rev reverb, you can get that sound down pat easily).

The sound editing on it is intuitive, but, not complete. You can't edit everything, but, it's got a lot of useful Easy Edit parameters. Most useful for quick editing and tone optimization is the ability to change the waveforms of the 4 operators from the panel.

The sequencer has a metronome mode which is quite loud and pervasive. It is added to the mix post volume control. This can be routed to a jack on the side very easily, so that when you put something in the jack it mutes it, or you can route it to another channel. Timing is pretty good the sequencer.

The effects chip has a digital stream in and out, and is thus glitchable, although, I've only done this to mine once or twice. It's too precious to lose to a circuit bending disaster.

I have service manual if anyone needs any questions asker. Although, I should take some internal photos and include instructions on clock out for y'all one day!

Did I mention it has a clock and a calender on it?

Korg X-911 synth - MS-20 style audio processing

via this auction
"this is a bit of a rare and strange one. For a start, it has no keyboard, because it's designed to be controlled by other sounds - it's known as a pitch-voltage synth.

What this means is you plug in your signal source (a guitar would be your standard thing this was designed for - but you can plug in anything you want - drum machines, a microphone, the latest britney single) and the X-911 tracks the pitch of what you are playing into it, and then plays that pitch with its built in synth.

which brings us to the other weird part of the X-911 - the synth part.. you have 2 separate sections. one is a basic subtractive synthesiser, and the other half is a bunch of presets. the really nuts thing is, all these presets can be stacked up, and mixed with the synth, to create a massive wall of noise. If you get into the guts of this thing there's some serious electronics packed into it - according to this site this is all the synth bits and pieces contained in this tiny little MS-20 era box

* 1 pre-amp, dist unit, P-V converter and envelope follower/trig detector
* 1 multi-waveform, multi-octave output MS-20-style VCO with both lin and log CV
* 1 MS-20-style VCF
* 3 MS-10-style VCF:s (discrete KORG35) used by the Bass, Tuba and Trumpet presets.
* 8 VCA:s
* 9 simple EG:s

of course, if all this is a bit much for you, the X-911 has CV and trigger jacks in and out, so you can control it from a midi-cv converter, or use it to control a synth with a more vanilla architecture."
