Serge Audio Matrix Mixer

You can find some images of the Control Voltage Mixer here.

Update via Bakis:
"a new Serge M-odule has just been released: the 'Audio Matrix Mixer' M-odule.

it contains (from left to right):
an ac-coupled Matrix Mixer, a Dual VCA (both ac-coupled) and another Dual VCA (also both vca's ac-coupled).

price is 1600 usd.

the audio matrix mixer module includes an extra attenuator in each of its 4 inputs, to control the amount of each sonic element that is applied to ALL 4 output mixes of the matrix.

also, inputs one and two include a phase inverting and muting switch.

so, just imagine the possibilities with this new m-odule...

for example, by mixing 3 audio sources (from NTO's, PCO's, DSG's, etc...) and using the 4th matrix mixer input to create feedback (after processing one mix of these 3 audio sources with another Serge sonic mangler) and also using the 4 ac-coupled vca's to introduce organic AM into your patches (either in the inputs or outputs of various devices), the tonal complexity you could achieve will be limitless...

i can personally recommend this m-odule, as i have the dc-coupled brother of this (the 'CV Matrix Mixer' m-odule) in my system and it is simply great."

Serge gets its name from Serge Tcherepnin (pronounced "Cher - epp - nin"), a multitalented composer and electronic designer born of Russian-Chinese parents and raised in France. Self-taught in electronic design and circuit building, Serge enjoyed doing 'junk electronic' projects early on, making tape compositions using various electronic noisemakers cobbled together out of transistor radios and the like.

After studying music and physics at Harvard and Princeton, he taught music composition at the California Institute of the Arts. This was the early 70's, the heyday of Moog, ARP, and Buchla synthesizers. Calarts had a few Buchla-equipped studios. These were expensive, highly sought-after instruments, kept under lock and key. Getting studio time on one at Calarts meant being either a recognized staff composer or someone who maneuvered themselves into favor. The Buchla, ARP, and Moog synthesizers were interesting in their way, but could be improved upon. They were both expensive and bulky, a system with a decent number of functions could take up a whole wall in a small room. Serge and students Rich Gold and Randy Cohen wondered what they could do about this. After kicking around some ideas, they decided they were going to do their own synthesizer.

The first modules were designed, soldered, and built at Serge's home in what was essentially a kitchen tabletop operation. Before long, the word got out to other professors, students, and musicians about this new synthesizer. They wanted a piece of the action. Serge set up a strange sort of guerrilla manufacturing operation at Calarts on a second-story courtyard balcony. People paid $700 upfront for parts, worked on the 'assembly line' soldering and building modules, and eventually got themselves a six-panel system. Somehow, the Calarts administration either didn't find out or wasn't too bothered by this.

Another interesting player in this drama was composer Morton Subotnik, a professor at Calarts. He had a long association with instrument designer Don Buchla in the early 60's, the two of them collaborating on fundamental aspects of synthesizer design. When Mort spoke, Don listened. Serge caught on to this, and sought to woo Morton away from the Buchlas, but that was difficult. Eventually, Serge did build Mort some custom equipment.

In the 70's Serge collaborated on the design and construction of TONTO, a large polyphonic modular system. TONTO had the ancestry of many early Serge designs, some packaged behind faux-Moog front panels, including the NTO.

Serge eventually quit teaching and began to build synthesizers more seriously, using the first designs as a springboard. The Serge company was started in 1975, in the West Hollywood area, then headed north to San Francisco's Haight Street a few years later. It was always a humble bohemian concern, running more on enthusiasm and the love of making music than money and hardheaded business sense. Business tapered to a trickle in the middle 80's, and Serge, to support his family, started doing various outside electronic consulting projects. In 1992 Serge decided to move back to France. It was at this point that he sold the closely-guarded circuit designs to longtime associate Rex Probe, who then founded Sound Transform Systems. Production record keeping was pretty informal; it's estimated that "hundreds" of Serge systems were produced in the early years.

Today, Serge is again doing musical composition and is involved in helping Russian Jews move to Israel.
As Moog was a powerful East Coast influence that inspired ARP and Polyfusion, Buchla was the West Coast influence on Serge. Several Buchla designs, including the use of touch sensitive nontraditional keyboards, sequencers, random voltage generators, function generators, and matrix mixers found their way into Serge's repertoire. But that's not to say that Serge is merely a Buchla clone. Serge made many unique contributions, including the wave multiplier module, and some ideas were taken to new heights. Serge's oscillator designs have extraordinary accuracy and stability, especially considering their discrete nature. His philosophy of allowing the easy interplay of audio, control, and trigger signals, combined with the use of banana plugs, makes these systems wonderfully flexible.

There's no denying the amazing staying power of the Serge designs. Largely because of the development of convenient microprocessor-based keyboard synths, the 80's were a nasty time for analog synthesizer makers, practically all of them throwing in the towel. Serge's business slowed way down but never completely went out of production. With the recent clamoring for analog gear fueling successful production, Rex Probe and Sound Transform Systems look poised to carry the cream of analog modular music synthesis over the threshold of the 21st century, into their fourth decade of realization.

Sound Transform Systems has done a great job of continuing the analog modular lineage. Most of the traditional Serge modules are there, a few old ones were dropped, a few new ones added. The details are constantly being improved in many visible and invisible ways. They are still laboriously handmade, though the entire build process has been improved. Turnaround time has been improved from several months to 'just a couple'. All the components are top notch. The panel graphics and layout of many of the modules have been redesigned to make them more compact while keeping or improving the functionality. The circuit designs on many modules have been updated."

Introducing the Nodular Desktop Synthesizer - Two Sided Analog Monophonic Semi-Modular Synthesizer

Note: Auction links are affiliate links for which the site may be compensated.

via this auction

Update: the maker/brand name for this synth is ndlr.synths. I created a new channel label for them. We have a new synthesizer manufacturer in town.  See second "Update" at the bottom of this post for additional notes on the design.

via the auction:
"Up for sale: one monophonic analog synthesizer. I've been making analog synthesizers for about 15 years now, but this is the first I am offering up for sale to the 'general public'. I am hoping to make a business out of selling this particular model, and you could be my very first customer.

The pictures show the same unit that is up for sale. The cabinet is made from 3/4" natural cherry boards, except for the base, which is made of 3/4" MDF. Both instrument panels are made of 1/8" thick anodized aluminum. The panels have been mechanically engraved and the engravings filled with chemically hardened black enamel paint. The whole unit measures about 18" wide by 18" deep by 12" tall. It weighs about 40 pounds. This is a very well made unit, with sturdy instrument panels that'll last a lifetime.

This synthesizer has its own +15/+10/GND/-10/-15 volt power supply and will only run on 120VAC 60Hz. It consumes about 45 watts of power at full bore.

All the modules in this synthesizer have been designed to work together seamlessly, and all use the same standards: 1 volt per octave, 10 volt peak-to-peak signal voltages, and 5 volt peak-to-peak gate, trigger, and control voltages. All patches are made among the modules via banana jacks. And a few different ways of interfacing to external modules or instruments are offered via 1/4" phone jacks.

A description of the different modules follows:

(1) ring modulator

(1) white and pink noise and random voltage source

(1) sample/track & hold

(1) voltage comparator

(2) low frequency oscillators (LFOs):

(1) headphone amplifier

Both offer voltage controlled frequency, variable offset and symmetry, and sinusoidal, triangular, and pulse wave outputs. By adjusting the speed knob, the frequency can be changed from about 20Hz down to really, really, slow. This range can be extended through voltage control.

(3) voltage controlled oscillators (VCOs):

All three offer 1 volt per octave frequency control, voltage controlled pulse width modulation, ac-coupled linear frequency control, hard sync, and sine, triangle, sawtooth, and pulse wave outputs. They'll track to within .2% over at least 8 octaves with basically negligible temperature drift once the enclosure is warmed up. And they'll operate from below audio to above audio frequencies.

In addition, the first VCO offers a frequency range switch and fine tuning.

Reaktor 5: Morphing Effects as Sound Generators using Feedback Matrix

YouTube via Veqtor
"Here's something I've been playing around with recently: using effects in feedback matrices and morphing between presets. I got the idea when playing around with frequency shifted feedback in a Serge modular system. So I created a crude macro that let's you morph between the presets, but intend to improve upon it before releasing it (morphing speed modulation, snapshot lists etc). A lot of effects in Reaktor unfortunatly use non-interpolating parameters, like switches (which is good for saving cpu), thus creating clicks when morphing. I will be creating a set of effects intended for morphing like this which are completely designed for morphing (complete with polarizing mod matrices and such). In this particular setup, grainstates fx, a stereo frequency shifter with a wide range and crossfade between up and down-shift, a spacemaster reverb and an analogic filter box are being mixed using a matrix mixer. This allows for any output to be sent to any input. All of the effects are morphing randomly between presets and so is the matrix mixer. Works quite well as a proof of concept if you ask me!"

ARP 2003 Synthesizer and 3003 Keyboard Controller

Title link takes you to shots via this auction.

Actually, yes this is an ARP 2500. The 2003 is the synthesizer and the 3003 is the keyboard controller.

Details:
"This is a very rare and early version of the ARP 2500 Modular Synthesizer. It has a larger cabinet with 3 x 5 Modules (instead of 2 x 6 Modules on standard ARP 2500s) and the switch matrix in the top section has 10 positions (instead of the 20 positions on later ARP 2500s). You will probably not miss the extra 10 switch positions as most patching is done on the lower matrix.

The ARP 2500 for sale here has the serial number 014 (model 2003, serial 70 - 014).

I have been told that these very early 2500s were hand-built by the ARP/Tonus crew to the most exacting standards, they are probably better than later models (which of course are excellent as well).

The synthesizer is in technically beautiful condition with all modules working 100%. It has a very powerful and clean sound and is set up for 3 voice multitimbral operation.

I haven't been able to locate the cables for connecting the keyboard to the main cabinet, so I can't guarantee full functionality for the keyboard. Last time I used it (about 10 years ago) it worked fine though.

The ARP 2500 can produce a huge range of sounds from fat to bold to shimmering to weird modulation extravaganzas. It also makes a great companion to a sampler with the capability to filter and modify up to 3 external sound sources. Samples with FM-modulated filters? Very crunchy!
There will be no sound degradation when inserting any external sound sources, the signal path is very quiet and clean sounding.

It has 4 oscillators (2 of them with invertible waveforms), 3 excellent 24dB Filters with resonance and built-in mixers for up to 4 audio and 2 CV signals (5 CV inputs per Filter total), 3 VCAs with built-in mixer for 2 CV signals (plus another 3 fixed voltage CV inputs), 6 Envelope Generators (4 of them with Gate Delays and normal & inverted outputs. All 6 Envelope Generators have a switch for single or multiple triggering), a fixed voltage source (i.e. to shift all Oscillators at once) and a pink/white noise source with built-in filters.

There is also the rather lovely model 1027 analog sequencer with 3x10 steps and individual trigger outs for each step. Voltage controllable pulse width. The internal clock is very fast and can be driven into the audio range. You can modulate it from any source and use it as a signal generator/VCO with a user definable waveshape (by setting the 10 steps of the sequencer to different voltages).

All oscillators/filters/etc. are very stable and easy to tune, very much unlike the modular systems built by Robert Moog (even Wendy Carlos found the ARP oscillators to be far superior to the Moog ones).

I have occasionally heard the complaint that the ARP 2500 doesn't have any "special" or more "esoteric" modules as seen on other modulars. The truth is that EVERY module on the ARP 2500 is special, only that this is not so obvious. The oscillators for example first of all sound excellent, they must rank among the best oscillators ever built. They have a very rich and nuanced sound, full of harmonics. They have an extremely wide audio range, from the lowest frequencies (they can also be used as VC-LFOs) to sounds well beyond the human hearing range. They don't start to "jitter" at any frequency like many other oscillators, even ones on quite expensive modular synthesizers. When cross-modulating or using them for FM, they remain stable and powerful sounding.

Another example for the ARP sound philosophy is the 1027 sequencer. This can function as a standard analog sequencer, but also works as an audio generator by driving it up into the audio range - this can be voltage-controlled, of course.

The closest comparison to an ARP 2500 is probably the Serge 79 modular system, which was built with a similar idea of technological excellence at the service of a great sounding musical instrument.

The power supply has been profesionally modified to work with 220-240 Volts, but can be reverted to 110-120 V operation.

Modules are:

1 - Module 1004-T Oscillator
2 - Module 1004-T Oscillator
3 - Module 1023 Dual Oscillator
4 - Module 1006 FiltAmp (24dB Filter & VCA)
5 - Module 1006 FiltAmp (24dB Filter & VCA)
6 - Module 1006 FiltAmp (24dB Filter & VCA)
7 - Module 1033 Dual Envelope Generator (each with Gate Delay and inverted Outputs)
8 - Module 1046 Quad Envelope (4x Envelope, 2x with Gate Delay, 2x inverted Outputs)
9 - Module 1027 Clocked Sequential Control Module (Double width Module)
10 - Self-built Output Module w/headphone amp
11 - Self-built Pink/White Noise Generator w/Filters & fixed voltage (very useful!)
12 - Module 1002 Power Control Module

Main Cabinet for a maximum of 19 modules, 15 modules with access to modulation matrix.
Keyboard w/ 5 octaves, lower octave with inverse colored keys.

The cabinet is in good condition but has some surface marks and scratches, as can be expected on an instrument close to 40 years old. On the top of the cabinet was a small spot were the surface was damaged, but this has been fixed with antique furniture wax (the wax is fully removable). There was some other small damage to some of the corners and edges of the cabinet, but this has been also fixed in the same way and looks o.k. The previous owner had scratched his initials "RMS" in small letters into one of the Keyboard Modules and into the Power Module of the main cabinet. This is not too visible and has never bothered me.

The keyboard cabinet is in similar condition to the main cabinet, there is some surface damage to the lower left hand corner. Please have a look at the photos below. It shouldn't be too much of an effort for a good carpenter to return the cabinet to its original condition.

This instrument was used in the last 15 years in a non-smoking studio environment and has performed beautifully and flawlessly during this time. I'm sure the next owner will enjoy it for a long time to come."

Grayscale Algorhythm and Binary - Random Logic Acid

Grayscale Algorhythm and Binary - Random Logic Acid from Joseph Fraioli on Vimeo.

"A patch built around the new Grayscale Algorhythm and Binary modules.

Main clock source for this patch is the Livewire Chaos Computer. The gate out is feeding the left most Algorhythm module, which is in random mode. The top row of outs is going into the left Binary module in OR mode. The output of the Binary is then triggering the Tip Top BD808 kick drum that is then fed into the Modcan Dual Delay.

The same Chaos Computer clock source is multed to the right Algorhythm with the same process applied to the Binary. The Binary output here is triggering the Mutable Instruments Braids in Meta mode. The output of Braids is multed into a mixer as well as a VCA. By manually triggering the a pressure points pressure output, the signal is sent to the Qu-Bit Electronix RT60 for reverb throws.

The main clock source is then multed into the 4ms shuffling clock multiplier and outputted to the Cylonix Shapeshifter via the x 2 output though a channel of the Make Noise Maths v2. A synced LFO from the Modcan Quad LFO is triggering the cycle input as well as another sine LFO is modulating the fall time.

The center Algorhythm is in seq mode and clocked by a divided by 8 of the original clock source via the 4ms Rotating Clock Divider. The eight outputs are triggering eight tuned vocal samples on the Qu-Bit Electronix Nebulae in one-shot mode. The Nebulae output is then run through the Serge Resonant EQ and the Tiptop Audio Z-DSP with the Halls Of Valhalla reverb card.

The Make Noise Wogglebug, DPO, Maths and MMG provide acidy baseline.

The outputs of the Shapeshifter and DPO are put through the WMD Sequential Switch Matrix to use as a simple mute system for performance.

At around 3:17 I got a call from my cat food delivery guy.

No computers or editing were used in the making of this performance."

"The case is made of curly oak top/front and ash sides/back (they match up really well) and has a couple STG Busboards with a Power One PSU that's really overbuilt for the case size. The modules are all in decent shape save for occasional rack rash that you don't see when screws are in place or some light scratches here or there from a patch lead, which is to be expected with an instrument that's frequently patched and used and nothing out of the ordinary. This system new with a case would cost well over $7,000 so this is a serious deal. Comes with a nice pile of hosa colored patch cables in 1.5 and 3ft lengths.

All modules are professionally built, even the DIY/synthcube modules so you know you'll be getting something to depend on for years to come...
