intellijel Dixie II

“Intellijel Dixie 2 Plus Triangle Core VCO. 8HP. Used but in excellent condition. A very handy and popular VCO for Eurorack with an octave switch, fine tune control and PW control for the square wave. It has hard sync, flip sync (soft sync), linear and exponential FM, PWM and switch for LFO mode.

I’ve always found it very stable and reliable, excellent quality. I’m just wanting to create some space in my case for a new module.” Click here to visit listing on eBay

Mutable Instruments Marbles

“Selling a used Mutable Instruments Marbles module. I bought this when they were released and unfortunately haven’t used it all that much. I should note up front, this is NOT an audio sampler like an akai or something for making beats, it is a random sampler in that it produces random gates and triggers for your eurorack system/synthesizer. I’ve used it to make interesting rhythms and pitches for a sound or drum source. Condition of the module is great, with the exception of a bit of rack rash on both the top and bottom of the plate, otherwise like new! I don’t have the original box, but will ship in a sturdy container.” Click here to visit listing on eBay

Physical condition good, as shown in pics. Keys move freely.
Note that I do not know how to operate it and have not tried to turn it on.
Therefore, it is listed as not working. I do know that it was assembled professionally and worked when built. Will probably need some restoration. ” Click here to visit listing on eBay

Lot of PAiA Modular Synthesizer Modules

“PAIA Synth Modules from the ’70’s. VCA,VCO,Envelope Generator. Sold AS-IS. Condition is “Used”.

These worked perfectly…40 years ago!!! So have to sell them as-is because I couldn’t test them.
Everything looks good but ya know, after so many years you might be replacing some capacitors. Who knows.
I had a whole PAIA rig that these came from, all in a custom wooden enclosure and used the synth playing out.” Click here to visit listing on eBay

PAiA Function Generator

Made by Paia Electronics
Circa 1983
This is a module that can generate Shepard Tones, also known as Barber pole tones. These are tones that appear to continously go up or down. It is an audio illusion. Look it up on youtube or google.
It requires a number of hook ups to a cv controlled synth.
Also look up Paia ek-9 to get the instructions and article by John Simonton (RIP John).
Great for you more adventurous modular synth guys out there.” Click here to visit listing on eBay

PAiA Fatman

“Paia Fatman Desktop Synth. Condition is “Used”.

I bought this on here from the original owner about a year ago before I knew very much about what kind of synth setup I want.

This unit is for someone who likes old school equipment and knows how to work on synths,etc.
I’m wanting something a bit more modern and automatic.

It has all the original paperwork and plans,I had it serviced with Thesis Audio over Christmas.”

Pittsburgh Modular Voltage Research Laboratory

“Pittsburgh Modular Synthesizers – Voltage Research Laboratory – Open Box.

This is basically a museum piece. It has a Frank Lloyd Wright / Stanley Kubrick vibe to it, and it’s so rare you can still launch your own YouTube channel with it.

Full Buchla-style analog voice with a dual complex oscillator, a dual function generator, two vactrol-less VCA/LPG/MMF dynamics controllers, and a very rich-sounding analog BBD delay. You can fold square waves and make all kinds of animal-like and organic sounding patches with this thing. It’s super rare, an undisclosed number were ever sold about a year an a half ago. Pittsburgh is making a VRL 2, but it will be substantially different to this. In addition to the VRL module, you get a the Lifeforms Touch controller, the Output Utility Module, and a walnut and steel 96 HP eurorack case. I’m selling this rare and inspiring instrument which has been played for under 10 hours. The rubber feet and many of the patch cables have not even been used. It will come shipped in the original box.” Click here to visit listing on eBay

Plan B Model 17 Triple Event Timer

“This is a Plan B Model 17 Triple Event Timer Eurorack Module PCB And Parts. Condition is “For parts or not working”.

This is the main PCB which is populated minus the ICs, a jack board, and a switch board for the module as well as some LEDs and Jacks. I built the board in 2006 while working at Plan B but never finished assembly due to parts shortages. Someone willing to DIY the rest could make a working module out of it. Sold as is.” < Click here to search for synths on eBay

SynthTech E355 Morphing Dual LFO

“The E355 is a 14hp Eurorack module with two LFOs that use our unique morphing algorithm to create over 10,000 different waveforms. the two outputs can vary from one cycle in 12 minutes to 1000Hz, with high and low ranges available. The use of a 24 MHz 32-bit ARM processor means virtually no frequency drift.

The E355 has features to make it useful in both live and in the studio. The two LFOs are “locked” to each other in one of three ways, chosen by a panel switch:

LFO1 and LFO2 have independent rates and the same waveshape and phase
LFO2 has independent waveshape but the same rate and phase as LFO1
LFO1 and LFO2 have the same rate/waveshape but variable phase from 0-360°

LFO1 can be thought of as the “master” LFO as it always has independent rate, FM, and morphing. Each LFO tracks 1v/Oct and all parameters are under voltage control. There are two leds that vary in brightness based on output amplitude in 128 levels.

The E355 uses the same morphing engine as the E350 Morphing Terrarium. The transition from one stored wavetable to another is broken down into 4096 calculated waves. There are 3 banks of waves to select from:

I use the module for percussion using bank B and C as well as normal LFO duties. Slight scratch at top of module (see picture).” Click here to search for synths on eBay

The Harvestman Polivoks VCF

“Harvestman Polivoks VCF Eurorack module in excellent condition, a few small marks on the faceplate but great overall.

One of the dirtier filters going, an exact clone of the filter from the Soviet Polivoks synth with new old stock soviet ICs, made in collaboration with the original designer.

Dual input with low pass and bandpass outputs. Sounds amazing but I have too many filters!” Click here to search for synths on eBay

PAiA 4700 Series Modular Synthesizer

” You’re bidding on an analog “patch cord” monophonic synthesizer that contains all of the fundamental modules needed for music synthesis. I assembled this synthesizer in 1980 using 4700-series kits from the legendary PAiA Electronics, Inc. in Oklahoma.

This synthesizer was in “working” condition before I stored it away. I was already an experienced electronic kit assembler at age 18 when I assembled all of the modules. I used terminal strips to create “bus bars” inside the module cabinets to conveniently provide the three supply voltages (plus ground) to all of the modules. Once I got to college at PSU I begged an Electrical Engineering professor let me use a frequency meter in a lab to calibrate each key of the keyboard to the proper pitch. I recently applied power to the cabinets and proved that the power supplies are working, but their output voltages will need to be recalibrated according to the manuals. I say that this unit is “working”, but I never really got it to make the sounds I was hoping for…” Click here to search for synths on eBay
