Turnkey Vintage Synthesizer Sale


Moog System 1 custom 55/35 modular 3C - £25,000

The ultimate modular synthesizer. Originally conceived by Dr Robert A. Moog in the mid sixties as a less bulky, more affordable alternative to the famous experimental RCA Mark 2 (which filled several rooms), it became the instrument that made synthesized music popular, especially thanks to Walter Carlos' album "Switched On Bach", a massive hit in 1968. Other artists, like Tangerine Dream, Klaus Schulze and Emerson, Lake & Palmer also explored the possibilities of the Moog in mainstream music and even used it for live performances. But the modular systems were generally too complex and expensive for most musicians, designed as they were for studio composition of electronic music, and Moog went on to produce more performance oriented instruments such as the brilliant Minimoog.


System 1 consists of 2 cabinets.

Cabinet 1
# 2 x 921A Oscillator Driver

$126,508.32 Massive Vintage Rare 1974 ARP 2500 in Superb Condition for Sale

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

via this auction, priced at $126,508.32 + $1,640.77 Shipping.

This one was spotted and sent in via an anonymous MATRIXSYNTH reader. It was once for sale back in August, 2017.

Details via the listing, captured for the archives:

"Selling my beloved ARP 2500 - Model 2515 Studio Cabinet. Serial number - 74-005

I am the second owner of this fantastic piece of history and purchased this instrument from a dutch composer/violinist who in turn ordered it directly from the Arp factory around 1976. Before my ownership, it was used in a reasonably well known studio in Hilversum for a multitude of experimental recordings throughout the 70s and 80s.

It is in pristine condition and original state with only a few cosmetic blemishes. It has been used and stored in a smoke free, temperature controlled environment and is a joy just to look at, let alone play. A well laid out collection of modules that offer many many years of deep exploration, I spent almost 6months just with the 1036(Sample/Hold/Random voltage) module :).

All modules are working and sounding fantastic. The filters are especially lush, definitely nothing else sounds like a 2500 and the unique matrix switch system is ripe territory for happy/accidental patching discoveries.
The fabulous ARP 2500 was used by famous musicians like Aphex Twin, Pete Townshend, Jean-Michel Jarre, Vangelis, Jimmy Edgar, Luke Vibert, Vince Clarke, Faust, Eliane Radigue. And used in films like Logan's Run and communicating with the aliens in Spielberg's Close Encounters of the Third Kind.

Here is your chance to own an instrument capable of taking you on an intergalactic journey through time and space...

New Doepfer A-147-2 Voltage Controlled Delayed LFO


via Doepfer, via PatchPierre.Net

"Module A-147-2 is the successor of the VCLFO A-147 but offers much more features than the predecessor. The module is made of these sub-units:

VCLFO: voltage controlled low frequency oscillator

VCA: voltage controlled amplifier, switchable to voltage controlled polarizer

VC delay unit: voltage controlled linear attack envelope (only one parameter: attack) for delayed LFO operation in combination with the VCA (e.g. delayed vibrato/tremolo)

LFO: The voltage controlled LFO has the waveforms Triangle, Sine, Sawtooth and Rectangle available and features a Reset/Sync input. Triangle/Sine and Rectangle are displayed by means of dual-color LEDs (probably red/green), Sawtooth has a unicolor LED available (probably blue). The output levels are about -4V...+4V for Triangle, Sine and Rectangle. The Sawtooth level is about 0...+8V.
The CV control can be switched to attenuator or polarizer ("CV Mode" switch). In polarizer mode the CV inputs affects the frequency in the reverse manner when the CV control is left from the center position. In the center position CV has no effect and right from the center the control works like a normal attenuator. The frequency range (without external CV) is from about 0,005 Hz (i.e. about 3 minutes per periode) to 200 Hz. In addition a ultra-low mode can be activated by means of an internal jumper. When the ultra-low jumper is set a fixed voltage is connected to the switching contact of the "LFO CV" socket. In polarizer mode of the CV control that way extremely low frequencies (up to one hour period and more) are possible.

VCA: This is a linear VCA that can be switched to "normal" VCA (i.e. kind of a voltage controlled attenuator) or voltage controlled polarizer ("VCA Mode" switch). In the "normal" VCA mode amplification +1 is achieved with about +5V control voltage. In polarizer mode the amplification ranges from about -0.5 (i.e. inverted signal with about 50% level) with 0V CV to +0.5 (i.e. non-inverted signal with about 50% level) with +5V CV. With about +2.5V CV the signal is suppressed. Details about the functioning of a voltage controlled polarizer can be found in the description of the module A-133. In this mode the VCA can be treated also a DC coupled ring modulator (similar to A-114).

The VCA of the A-147-2 has three sockets available: "In" (signal input), "Out" (signal output) and "CV" (control voltage input).

The Triangle Output of the LFO is normalled to the VCA signal input by means of the switching contact of the "VCA In" socket. If another LFO waveform (or any other signal) should be processed by the VCA the corresponding signal has to be patched to the "VCA In" socket. The VCA can be used also independently from the LFO and the Delay CV. In this case the VCA sockets In, Out and CV have to be patched accordingly. The VCA can be used also as waveshaper for the LFO signals (e.g. by patching VCA In and VCA CV to different LFO signals, if necessary via attenuator A-183-1 or offset generator/attenuator A-183-2).

Attack/Delay: The third sub-unit of the module is a simple, voltage controlled envelope generator that has only the parameter "Delay" (or Attack) available. This unit generates a linear increasing voltage that starts from 0V after each Delay Reset until it reaches about +5V. Then the voltage remains at +5V until the next Delay Reset occurs. The inclination or gradient is controlled by the manual Delay control and the Delay control voltage ("Delay CV" input). The waveform is linear, the control scale is exponential. The output voltage is displayed by a unicolor LED (probably orange) and available at the "Delay Out" socket.

The manual Delay control ranges - without external "Delay CV" - from about 5ms (fully CW) up to 2 minutes (fully CCW). By means of an external voltage applied to the "Delay CV" socket this range can be extended. A rising CV shortens the delay time (behaviour like a VCO) !

The Delay output voltage ranges from about 0V to +5V. The rising edge of the gate, clock or trigger signal applied to the "Delay Reset" sockets resets the Delay output voltage to 0 V.

"Delay Out" is normalled to the VCA CV input by means of the switching contact of the "VCA CV" socket and consequently controls the Triangle level provided that no other patch is made. A typical example is the usage of a Gate signal (e.g. from a USB/Midi-to-CV/Gate interface) as Delay Reset. That way a delayed vibrato or tremolo can be realized if the VCA output is patched to the frequency CV input of a VCO (or VCF), or the CV input of a VCA.

But the Delay sub-unit can be used also independently from the LFO and VCA, e.g. as a voltage controlled waveshaper or for other applications where a linear increasing signal with voltage controlled steepness is required."

ARP 2500 Modular Analog Synthesizer for Sale

via weisma where you'll also find a 2600 and 1611 sequencer.

"In the 1960s I was one of the pioneers of contemporary electronic music in the Netherlands. In the 1970’s, when the portable ARP 2600 synthesizer was created by ARP Instruments, Inc., I decided to start my private electronic music studio “Five Roses”, using the ARP 2600 for studio compositions as well as live electro-acoustic performances. At a later stage, when the modular ARP 2500 synthesizer was introduced, I expanded the capabilities my studio step by step.

The ARP synthesizers have been the center of my work for many years, but as electronic music became mainstream, my focus shifted to acoustic contemporary music. It is therefore that I have decided to put up my now classical ARP 2500 and 2600 synthesizers for sale for the collector, or for the musician that wishes to explore the unique sound of these landmark analog synthesizers."

* led display of the 5 different current modes and one led for loop/one-shot display

* manual and voltage controlled selection (with attenuator) of the running mode. if no external control voltage is applied one of the 10 modes (5 modes x 2 loop/one-shot) is simply selected with a rotary knob. the cv input with attenuator is used to modulate the running mode with an external control voltage (digital high/low cv to switch between two modes or continuous analog cv to sweep through different modes). with the combination of manual control and cv with attenuator it is possible e.g. to use only two neighbouring modes (e.g. forward/backward) or sweep through all possible running modes

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.

Roland System 700 | Axiom


Published on Jan 24, 2020 Alex Ball

New overview video posted here.

"The System 700 from 1976 was the most expensive instrument Roland ever made. A comprehensive, semi-modular monster that was at the cutting edge at the time, the full system cost the equivalent of around £35,000 - £45,000 (around $45,000 - $50,000) and as they made so few of them; they have been known to sell for even more than that on the rare occasions that they emerge on the second hand market.

Huge thanks to the owner of this remarkable instrument for the very generous loan.

We have the main console and two of the “blocks” present but the full system has two further wing cabinets containing six additional VCOs, two further filters, three further VCAs, six further envelopes, another LFO, S/H, mixer and two further multiple jacks. In addition it has a twelve stage, three-channel sequencer that also acts as a switching mixer.

With the three blocks I borrowed I do have all of the modules present with the exception of the gate delay and I can use alternative sequencers in place of the original, so I feel this is a full representation of this marvelous instrument and what it can do.

New Pittsburgh Modular Eurorack BENDER Module


via Pittsburgh Modular

"The Bender is a dual voltage controlled low frequency oscillator built around two triangle core, wide range, low frequency waveform generators. A low frequency cousin to the Generator, this multipurpose signal generator can provide the basis of a wide range of complex modulations ideal for amplitude, frequency and timbral modulation.

The Bender module is split into two separate voltage controlled LFOs. Each LFO is controlled by a separate rate konb, range switch, control voltage input attenuator, and variable waveshape knob.

The two LFOs of the Bender module are wired together internally for frequency cross modulation. The Variable Waveform output of each LFO is wired to the Rate CV input of the other. This controlled feedback loop creates everything from rhythmic patterns to wild, chaotic modulations. The internal connections can be broken by inserting a patch cable in the Rate CV Input jack.

MSRP: $139
Available: February"

New Syntaxis Micromodular Starter Set


Krzychu1995

"!!! Available immediatelly at http://syntaxis.com.pl !!!
Today I have something very special to show. In this video you can see and hear synth made from Syntaxis Micromodular set. Instrument is assembled from basic set of micromodules (uVCO, uVCF, uVCA, uLFO and uADSR), but it sounds quite versatile. User is able to assemble synthesizer on it's own, in modular way, but much cheaper and without necessity of use dedicated multipliers - breadboard does it already! Usually building subassemblies of synths on breadboard makes circuit unreliable in longer term. But with Micromodules it works like it was soldered together - you can assemble you own synth, get plywood, drill holes for potentiometers, screw them in place and carry your own synth around for gigs."


"This is a set of components for building a basic but complete analog synthesizer on a breadboard. Although it might not have professional look, you will be surprised with its professional sound.

The set includes:

μPSU·112·A
μVCO·3340·A
μVCF·3320·LP4·A
μVCA·3360·LIN·A
μADSR·3310·A
μLFO·3340·A
