"Silent Rage" - Rhodes Chroma Compositions
Via Chris Ryan on the Rhodes Chroma list:
"I've posted a couple of recordings contributed by Chris Smalt [21010280+], who recently rejoined us after an absence of many years. An original composition, 'Silent Rage,' is '13 tracks of Chroma, [Update via Chris: "Just to be clear, it's not 13 tracks in the sense of separate compositions or audio files; it's 13 tracks in the sense of multitrack. Worth hearing! "] all mono, no chorus, just reverb and some delay added. Some rhythm provided by rubbing hands, snapping fingers and tapping the mic stand with my foot. The sounds are a mix of factory presets and custom patches. The track was originally published in 1999 on a 7-CD compilation called 'Bohemian R.A.P. CD', that included tracks recorded by various contributors to the rec.audio.pro usenet group.'
Also an audience recording, possibly of Peter Vettese, from the 1984 Musicom trade show. Chris writes, 'almost 20 minutes of non-stop live playing two Chromas and a Polaris (and briefly a Rhodes), straight into the PA, no effects, no sequencing. ... At a time when everyone was looking to sound digital and sequenced, here was someone improvising live, just hopping through some presets, retuning the instrument by ear, using a musical idiom and sounds that weren't hip at all. What he showed off in particular was the flexibility of the Chroma when played live.'"

Oberheim SEM Modded
images via this auction"Oberheim Synthesizer Expander Module model CPS-1, S/N 508. The SEM was Oberheim's first official analog synthesizer. It was conceived with the notion of being used as a backup synth connected to a sequencer for layering or beefing up your existing monophonic analog synths. The SEM itself is a keyboard-less module with two analog oscillators, a 2-pole filter, ADR envelopes, and an LFO. Each of the two oscillators offer triangle or rectangular waveforms."

EChucK Miniature Module Synth
via Inventor on this electro-music.com thread:
"Hi, I get positive responses when I mention this project so I thought it would be worth doing. It is a simple, inexpensive, miniature synthesizer. Instead of being rack-mounted with panels and jacks and cables, it exists as little bitty circuit boards that get hooked together by wire.
Circuits will be very simple one-chip dealies, classic opamp and 555 type circuits, passive and active filters. Pots are thumbwheel type and switches are DIP switches or similar. Interconnect is with mini-screw terminals or to save cost, soldered wire.
The boards may be arranged in any configuration physically. If you want to make a ring of three oscillators, well, that would look like a ring. You could make a BuckyBall or a Christmas Tree with LED modules that responded to microphone input, flashing the lights in response for example. So the system is it's own block diagram, physically in 3D space.
In exchange for super low-cost and 3D structure, we give up precision and quality. This is not the synth that you create your masterpiece on, it is the synth that you play with your kids on. Or make a gift for your loved ones. It's a poor man's synth, so to speak.
So I was advised to write this post to evaluate interest in the project. I've just created two of the initial modules and I am having fun with it, but the real fun is in collaboration and working as a team. I really enjoy the community spirit of electro-music.com and I'd like to participate in this way. Oh, the boards would be sold through electro-music.com just like the klee, etc.
So what do you think?"
Followed by:
"I have just thrown together a quick and slightly humorous little web page with a description of EChucK plus links to the first two boards: a 9V power board and a microphone input board. The page is here:
http://www.freedomodds.com/music/echuck/index.html
Have a look, have a laugh, and enjoy thinking about the concept, whether you are interested enough to participate or not. Oh, and thanks for clicking on the poll above, that helps."
Excerpt for the archives:
"EChucK is Born!
Conceived in the mind of a genius paranoid schizophrenic (that's me), EChucK was born in mid 2008. EChucK is a very inexpensive modular synthesizer that breaks all the traditional synthesizer rules!
Rather than mount expensive, super-accurate circuits in a rack and patch it together with connectors and cables, in EChucK we connect little bitty circuit boards with classic analog and digital circuits together using stripped wires. Instead of paying hundreds of dollars US for each module, EChucK modules will tend to be around ten dollars US or so each.
Because of the distributed nature of EChucK modules, we can build geometric structures like chains, rings, BuckyBalls, or Christmas trees - the possibilities are endless. In addition to having a life of its own, EChucK modules can connect to the audio i/o of your computer for interfacing to any software you like including ChucK, iTunes, and Audacity. You can even send out audio to a guitar amp or stereo for loud jammin' tunes - or your studio equipment for that matter.
EChucK is also inexpensive enough to be sold as a toy for young teens and older kids, plus it brings out the kid in adults as well. This is the main page for EChucK, see below for links to the open source hardware and software that fun-loving enthusiasts have contributed for you to enjoy. It's all free (protected by the GNU General Public License) except the hardware, which is low in cost. So read on and enjoy EChucK, it's a blast!"

Custom Printed Moog Stickers and a Polymoog Case
via Elhardt on AH:
"Since I'm going to be parting out my Polymoog, I figured my lid which is in almost new condition might be something somebody would want to buy to make their Polymoog look new. However, since day one that back Moog sticker was all scraped up (this was Moog's NAMM demo) making that part not look new.
So I spent several hours in Corel Draw, measuring and drawing up a new Polymoog sticker to replace the one there. Since the print shop has a minimum order cost, I had to print a bunch of extras including different sizes and colors, plus I went with the additional high-gloss laminated coating over the top which looks beautiful. Printed on Orajet vinyl stickers. So if anybody needs Moog stickers to replace damaged or missing ones on either a Polymoog, the back of a Multimoog or to replace the missing plastic logo on the front of a Multimoog, or if you just want a Moog bumper sticker, or to put Moog stickers on other manufacturer's gear to increase its value to Moog vintage prices, or for any other reason, then here's pricing and sticker details below. Note, if for some reason there's more of a demand than I expected, I can always have more printed up, including other sizes too, and even possibly with user requested text put right in the sticker, such as your name, synth SN#, etc.
Minimum order $6 Paypal, free mailing to US (and probably free to Canada and
Europe assuming mailing a letter isn't outrageous)
(1) $6, Polymoog Sticker 7" x 2-3/8" with the rounded rectangle around the edge. I have several in black, and one each in the colors at picture below. (2) $6, Polymoog Sized Sticker but without the white rectagular boarder. White logo, black backgrount. Looks stately without being pretentious.
(3) $4, Multimoog Back Side Sticker, Moog text is 4-3/16". Black background, White logo.
(4) $2, Multimoog Front Logo Plate Sticker Replacement, Moog text is 2-1/2" wide. Black background, White logo.
If your interested in purchasing, email me what you want so I can see if I still have any left.

The Poor Man's Memorymoog - adamstan's DIY Polysynth
via adamstan in this VSE thread. Be sure to check out the thread for follow up posts. The following is the first post in entirety. The reason why I captured it in entirety is so that we do not lose this. When I first started MATRIXSYNTH I linked to VSE threads only to find out they expired and dissapeared over time. That info is lost forever. That said, enjoy this one. It is pretty amazing. Be sure to listen to some of the sound samples below. I found this gem on Sequence 15.
"After almost 2 years of work, I've finished my DIY polysynth :D :D It is based on various module designs available on the net. I consider it to be a "Poor mans Memorymoog" with a little bit of Prophet 5 thrown in ;-). It features:
- 5 voices
- 2xVCO per voice
- 3xEG per voice (hardwired to pitch, cutoff and volume)
- 3xLFO (pitch, cutoff and PWM)
- Moog ladder VCF
- Noise source
- Ring Modulator
- Patch memory (128 user patches)
- MIDI
- Mono mode with selectable note priority (High/Low) and triggering (single/multi) and with portamento
- unison with adjustable detuning
VCO A offers sawtooth, square and triangle. VCO B offers sawtooth and square waves. Having triangle wave available is essential if you want to obtain some nice fm-like sounds from RingMod.
It's built using only standard off-the-shelf components - no CEM or SSM or similar chips inside - only typical opamps, switches, transistors etc.
Case (together with keyboard) was salvaged from some crappy 70's combo organ.
Here it is sitting on a stand (photo made with phone - sorry ):
With front panel lifted up:
With keyboard lifted up (showing voicecards):
Main digital board (keyboard scan, voice assignement and patch memory):
Voicecards close-up:
Front panel close-up [I love the rever keys for bass]:

It is noisy and tuning drifts a little bit, but hey, isn't that what we love vintage synths for?"

Oakley Voltage Controlled 'Cascaded OTA' Filter
"This is a four pole multimode filter capable of -24dB/octave low pass, -12dB/octave low pass and +/-6dB/octave bandpass outputs simultaneously. The filter core is based on four identical cascaded current controlled integrators. This is similar to the topology found on the filters in the SH series of monosynths as well as the CEM3320, IR3109 and SSM2040 filters of the classic polyphonics.At high resonance, we call it 'feedback', the COTA VCF will oscillate well over the whole of the audio band with a clean sinewave. Its temperature compensated too. The module also features a feedback input. This is similar to the one we introduced in the groundbreaking Multiladder module. In conjunction with the 24dB/octave output this input allows the resonance signal path to be split. This means that additional modules can process the resonance loop independentally. This allows a large variety of new timbres to be created. And it also allows for voltage controlled resonance with the use of an extra single VCA module.
The design is intended to fit into a 1U wide 'filter-core' module or a more fully featured 2U wide panel with seven control pots."

Doepfer 3 x A180 multiples for portable suitecase
Hielo Patagonia Sounds has a post up on a small DIY project to modify the Doepfer portable suitecase with multiples along the top.
The top strip outlined in blue is where the multiples will go."The trick will be to use 3 Doepfer A-180 modules and unscrew them from theirs faceplates. Then, use a square aluminium tube (20 x 20 mm - thickness 1 mm), drill some holes in it and screw again the Doepfer modules inside the tube. At the end, just drill two holes in the top wood part of a portable suitcase and screw the new 'Doepfer 3 x A180 multiples in a tube'."
