Octave CAT SRM II
Title link takes you to shots via this auction."The Cat is similar to the ARP Odyssey, but not as similar as some people think. Things that make this synthesizer unique are: The 2-voice keyboard, which has a second sample-and-hold for the second voice, so both notes die out when you let go of the keys. Each oscillator has a sub-octave output allowing you to get 4 separate notes from the machine at once (although two must be octaves of the other two). VCO 1 also has a triangle wave output, which ARP left off of the Odyssey. Finally, the keyboard is switchable between 2-voice (poly) and 1-voice (mono) modes, allowing you to work monophonically if you want to. The ARP can't do that, so if you're using the ARP's ring modulator you will get random timbres if you aren't careful to release each key before pressing the next one.------ Dave Wilson from synthmuseum.com"
Also see this post for a video demonstration including differnces of the SRM 1 and 2.

Update via the comments:
"No..no..no, this picture is definitely not from the original Halloween session back in June 1978*. I'm pretty sure it was taken during the Halloween III sessions at Alan Howarth's Pi West Electronic Music Studio, Glendale CA, ca. June/July 1982.
* the music for the original Halloween movie was recorded at Sound Arts, Los Angeles and featured Moog modular programming by Dan Wyman."

YouTube via DrSqu
"Casio VL-1 is a cult of the mini synthesizers. Monophon, build between 1981 and 1984. It inclouds a synthesizer, sequencer and a calculator. In this demo is show some funny things about it. Do you remember the song "Da da da" by "Trio" in 1982? Here, 25 years after, you'll see how to play it right. And with yout hands you also have a wah-wah ;) Interessting is the synthesis with some waveforms, ADSSR and 2 LFOs."

An XR-2206 Non-Hint
via Thomas Henry on electromusic-com:
"In my VCO Chip Cookbook, I mention that the four quadrant multiplier in the XR-2206 would be lousy as a VCA. In fact, I had a chance to find out just how bad it is this past week.
I've developed a rather unusual electronic percussion synthesizer with no commercial equivalent, and among the chips in it is the XR-2206. Somewhere along the way in the design cycle I thought I might use the internal multiplier as a VCA and save a chip or two. I figured, even as bad as I knew it to be, it would be okay for percussive sounds.
In a nutshell, no way! Even for simple VCA applications, this chip stinks. There are several problems. First, "off" means down -55dB which is still very audible. Second, it's hard to find "off" in the first place---it corresponds to a control voltage around 1/2V+, meaning that a trimmer will be needed. Third, even in the "off" position, the amount of background hiss is quite objectionable.
Like I say, I thought I might get away with it in this situation, but it's clear the unit is abysmal even as a simple VCA for percussion.
However, the story has a good ending. I wound up using the multiplier as a ring modulator, and in this context it's great! I probably wouldn't have considered that option before, but didn't want to waste part of the chip.
So again, in the XR-2206: VCA no, ring modulator yes. I hope this saves someone else a wasted evening pursuing that which doesn't exist! By the way, the new circuit is the most difficult one I've ever pulled off. It took a solid 14 twelve-hour days to get it right. See what I do for summer vacations!
Finally, I figured out another way to put the XR-2206 under exponential control. (There's one version in the VCO Chip Cookbook that is particularly powerful, but this new method is ideal for non-critical applications like tuning the drums via a keyboard). When I get a chance, I'll draw it up and share it here.
Thomas Henry"

"A slow, strong piece, thoughtful and beautifully performed. This is a Jackson guitar using a Roland GR-20 guitar synthesizer, one of Tedd's best works. The audio can be downloaded here. The footage is taken from "A Trip Down Market Street 1905", also from the Internet Archive, I urge you to view that version, as I ended up clipping off several minutes of it for this purpose. This is San Francisco before the earthquakes."

PAiA 2720
Click here for shots via this auction
"This auction is for a 1974 Paia model 2720 Modular Synthesizer. The synth includes 13 patch cables and 5 audio cables and a complete set of manuals for every module as well as the assembly instructions, patch diagrams, and a user manual.
The 2720 was sold as a kit of parts and was the first synth to incorporate, in one unit, its own power supply, all electronic analog music modules and an integral keyboard controller. As opposed to earlier models, it can literally be moved to any location and simply plugged in. The synth was designed by John Simonton, Paia founder. The synth is completely operational and like new with the following flaws noted:A rubber foot on the front right corner has disintegrated.
The low 'B' key on the controller sticks a little.
Keyboard calibration is off and needs to be re-aligned (a periodic task)
The synth has not been used for many years, but was recently activated to record some vintage sounds. The synth has a lot of historical value and is extremely educational since it uses very basic components to electronically generate sounds. I am the original owner and builder and now need the space for some more equipment. Here are the components of the 2720:
Power Supply - with variable outputs
VCO - Voltage Controlled Oscillator w/3 wave shapes
ASD - forerunner to the ADSR called a Function Generator
LFO - Low Frequency Oscillator w/ 3 bands and variable frequency
Noise generator
Band Pass Filter w/Q control
Low Pass Filter w/control
VCA - Voltage Control Amplifier w/ control
Keyboard Controller
Variable Pitch and Trigger shapes for the Keyboard Controller
More info on this synth can be found at JohnnyPumphandle.com Shipping weight is about 20 pounds"

Korg Mono/Poly
via this auction. Note this one is from Ben of Korg Kornucopia. More pics. "Click here to hear some mp3 audio files of the actual instrument I am auctioning (you may need to click on the 'MP4' icon that appears). I kind of threw these together without a great deal of forward planning but they hopefully go some way to demonstrate what a capable and FUN synth the Monopoly is.The audio tracks described :
* 1.mp3 :- the Monopoly arpeggiator in full swing. I have attempted to cram as many different arpeggio modes and routing modulations as possible into 4 minutes, including portamento, FM, sync and cross modulation, VCF and pulsewidth modulations and pitch effects, as well as effects with switching off VCOs and piling them up in unison. I told you this synth is fun!
* 2.mp3 :- analogue sequencer control of the Monopoly via Trig and CV inputs (by a Frostwave Fat Controller)
* 3.mp3 :- Monopoly arpeggiator external clock control by Korg KR-55 rhythm machine. The KR-55 has various output trigger resolutions which give the different effects.
* mp4.mp3 :- More arpeggiator hell ;-) The Monopoly is fed into a Korg SE-300 tape delay and reverberation (right channel) for extra dimension."

"Here's another Roland RE201 we're just about ready to put up for sale. This no-frills clip demonstrates a 1 bar bell sequence from a Yamaha QY series mini workstation / paperweight being effected by the tape delay section of the Space Echo. Kind of brings me back to a nightmare I had where the icecream truck just wouldn't go away. :) But anyway, the first few seconds are without effect, then echo modes are manually switched and tape speed's tweaked a couple times too. We love Space Echos! Enjoy. Email us anytime at minime123@onebox.com"

Image-Line Morphine Additive Soft Synth
Title link takes you to more including a downloadable demo and samples on the top right. Also check out their other soft synths to the left when you get there."Morphine’s 128 harmonic oscillator engine is fully optimized for producing a high quality, warm sound, with ground shaking bass and crystal clear high frequencies. Based on complex, full 32 bit mathematics, with no internal sampling to avoid interpolation noises so Morphine retains that 'analog' quality.
The oscillators are also optimized for fast amplitude and frequency modulation response for accurate tone reproduction.
The oscillator engine is not only thing that makes Morphine sound so great. With an infinite number of harmonic snapshots 'per-spectrum', and the ability to map a unique spectra for each note, you can generate a realistic and balanced sound over the entire keyboard range.
Additionally, the four generator sources can be morphed via the in-built mix/morph envelope or from an external MIDI controller. Combined with the four independent multipoint modulation envelopes, assignable to many internal parameters, you can achieve any sound, just like you imagined it.
As an ‘Easter-egg’ for the sound designers among you, Morphine provides unison and comb/pulse width filter modulation of the harmonics directly, adding even more motion to the sound.
Resynthesis
Be inspired. Resynthesis allows you to capture a complete spectrum from any audio sample, for accurate emulation of real instruments, or as a starting point for something completely new, using the in-built editing tools. Unlike the resynthesis of other additive synthesizers, Morphine provides total control so the resynthesized sounds are as close to the original sample as possible."

banana frac
Click here for more shots. Note this is for sale via david[AT]davidrothbaum.com
WIARD:
1) noise ring (the chance input jack does not work as designed. since this was one of my first banana conversions i was unsure of how to deal with switching jacks! and so since the chance input is/was switching i simply did not convert it properly and it is just connected to the main output, which of course is totally silly. the proper conversion can be done by rewiring it with a switch as i did on quite a few modules after this one. I just never got around to completing this one).
2) boogie filter
3) borg filter
BLACET:
4) oscillator
5) oscillator
6) time machine
7) quad vca
(this one is probably the funkiest. First of all the main output has been converted to a 1/4" jack. secondly none of the CV jacks are connected and the alt output had been changed to work as a banana to 1/8" converter. So this module now functions as a basic 4 to1 mixer with gain on the 4th channel).
8) micro lfo
(the rate & gate inputs as well as the two outputs at the bottom left of the
module were not converted to banana jacks -- this is because the plugs are mounted to
the boards)
MOTM:
9) ladder filter
BANANALOGUE
10) 3-P
TELLUN:
11) neural agonizer (this is a custom built module i built myself. The panel i designed using front panel express to fit the frac format. there were a few switching jacks that i did not convert for the sake of simplicity. as with the noise ring, one could add switches to these to make them banana if you want to. Another important thing with this module is that the boards were designed to work with a MOTM sized system so they are quite large (there are two for this module). and so the way i did it was to NOT mount the boards to the panel at all but simply screw it to the bottom of the case. You can do this to one of the Blacet frac racks if you want using standoffs which is how i did it before i made the wood case. The module uses the two very large 3 spring accutronics reverb tanks that are mounted on the back of the case.

MOOG Multimoog
Title link takes you to shots via this auction."one of the most rare Moog synths-less than 1,000 were ever manufactured. (They were made in the late 1970's, maybe until 1980 or 81 at the latest.) It's an awesome sounding synth , with that unmistakabley rich warm analog sound you get from Moog oscillators and filters. This synth has 2 oscillators, and tons of routing possibilities for the modulation and ribbon controller. The ribbon is a very cool feature, as are the touch sensitive keys which allow you to vary the amount of modulation you bring in depending on how hard you depress the key. This model was loaded with a surprising amount of features for a synth this size, and some of them, such as the keyboard touch feature or the ability to morph from one waveform into another, are definitely unique to the Multimoog."
