MATRIXSYNTH

"This is a sort of clone of the EMS Synthi A. Well, not a clone really, since it has none of the electronics like the EMS, nor has it the complete amount of functions. It is also smaller then the original. I wanted a synth that could do the typical effect sounds that the Synthi A is known for. At first, I designed an even smaller synth, with a minimum of modules and functions, and no pin matrix. But after a while I realized this design would be far too limited, and I also wanted the routing capability of a matrix. So this is what it turned out to be. I used a lot of stuff that I happened to have laying around in the junc box; like the 10x10 pin matrix, a small reverb tank, CEM3340:s etc."

Solar photosynth

"Synthstick circuit with resistor replacing potentiometer. Circuit powered by three solar cells. Instrument has no moving parts; "played" in manner similar to that of theremin or tannerin, regardless of vast differences between it and the other instruments."

Solar powered?

The Waldorf Wave to be exact.

Update via Till "Qwave" Kopper in the comments:
"... and it is my WAVE +16 (= 32 voice) shown here. A snapshot by someone taken during my last year's Planetarium concert of "EL-KA" (http://el-ka.synthmusic.info german only) in Bochum/Germany.
If you look to the yellow Waldorf Q in the back, you will notice the joy-stick someone added to my instrument.
Here is one from the other direction:
http://el-ka.synthmusic.info/el-ka_bochum_2006.jpg
You will see the other half of EL-KA there: HaJo Liese.
The CD recording is available at www.syngate.net and other EM music shops. And we will play at the Univercity of Eindhoven/The Netherlands next week's Saturday at the E-Day (http://e-day.groove.nl)

And by the way: I run the unofficial Waldorf WAVE pages located here:

keep on turning these knobs

KORG Poly61 Scans

Title link takes you to some scans of the KORG Poly61. Interestingly, the Poly61 had a discrete filter. I always assumed it was either an SSM or CEM filter, but I never had reason to look it up.

Update: be sure to check out the comments for more info on the filter.

"Something I made with MS Paint (and a famous kitsch painting) back in 1996."

Synton Syrinx

Click here for shots pulled via this auction. Interestingly this is the second one up for auction this month. They are extremely rare. Via the previous auction:
"There are 300 Syrinxes on this planet. 3 of them are white, 20 of them are blue, 20 of them are red and the rest is black. 2 BPFs and a LPF all with cut/peak control at the same time. also strange bending sensor and modulator. HARDWARE: 2 CEM3310 EG 2 CEM3340 VCO 2 CEM3350 Dual VCF 1 CEM3360 Dual VCA."

This one sent my way via the seller.

Starkey Hearing Laboratory Analog Modular Synthesizer

Title link takes you to more shots via this auction. Be sure to check them out. There are some great shots including a drawing of one, and a University of Illinois face plate.

Details:

"This machine was manufactured in 1972. The HSL-II has 3 sine wave generators, a square and saw wave fuzz generator (awesome!), and a pink and white noise generator. These can be seen clearly on the far left of the HSL-II. The signal path flows from left to right and is patchable with mini-banana cables (included in the auction). There are 3 filters which allow patching through hi/lo/mid pass sections. There is a phase inverter, limiter, frequency counter (with a classic red LED display) , 4 attenuators (volume), 2 mixer sections, a VU meter, and a few mystery functions that affect the sound but that I am not qualified to describe. there is also a gate sequencer, so you can basically set two different lengths of tones to trigger as you desire. The sequencer is weird and rudimentary, but functions perfectly.

Below are some long recordings of the HSL-II into a Deltalab Effectron Jr. digital delay. I ran this into a decent DJ mixer and into apple's Garageband. I clipped up the audio to make it a little shorter and give you an idea of a portion of the range that you can achieve with the HSL-II.

HSL-II sample one

Sound plays at beginning and towards the end - dead air in the middle

HSL-II sample two - plays fine

You cannot control the pitch from an external controller as of now. They were not designed for that. You can control the frequency manually, which in turn affects the perceived pitch, and believe me, with all 4 or 5 sound sources going through some delay and reverb, you have a wicked modular synth, sample source, drone machine....Silver Apples meets Aphex meets Eno.

I spoke with a synthe technologiste who thought that there would likely be a way to add c/v control to the sound source circuits...I have included a close up of a single sine sound source...it is the one circuit photo that has had the color altered and sharpened to give someone some idea what they are dealing with if they are so inclined to pursue the c/v route. Alas, there are no schematics and I have searched high and low on the internets.

The cabinet is absolutely VCS3-esque. There are a few areas of flaky veneer about the edges, as can be seen in the photos.

Also...you can run audio through the filters and even do some sort of weird sonic destruction by patching the fuzz output into the same input as the audio source. There are many many routing capabilities. These machines have provided me with plenty of inspiration. I will be moving soon, so please look out for all sorts of audio related stuff."
