"This collection of vintage synthesizers has grown with me for years. Most all of these instruments have been used on many projects, including VeggieTales, a variety of remixes, and many PlayStation video games and marketing and promotional discs. Most recently they were used on the Mass Effect Andromeda video games soundtrack. They have also been sampled and are part of the SoundVault Collection and the Kurzweil Analog Collection for the K2000 series samplers.
VEMIA note: to forestall many inquiries, The seller’s idea is that he wants to sell it as a whole. That may or may not work out in this auction. If it doesn’t, obviously he’ll be free to do whatever he wants after the auction finishes.

It all works. Everything has been kept in a clean, smoke-free, climate-controlled studio. I have always fixed things myself, so everything is operational and sounding great. I have repair notes on the synths that received attention, though most of them have worked great over the years, without much need for repairs. There are also several MIDI to CV converters so they can all be controlled by computer, plus cables if desired. And a few have cases and manuals.

"Vintage 1978 Arp Avatar analog synth module, with Arturia Keystep keyboard controller w/ built in sequencer and midi to cv. Basically a vintage late 70s odyssey mkIII in a module format.

"In proper fully working order all around. Fat rich wild & crazy sounds abound for endless exploration and creative real time variations.

Has typical wear/marks being 45yrs old. Bigger & heavier than an odyssey...all solid steel case, no plastic or aluminum like ody's."

"This is a really cool and very rare synth. It's an ARP Avatar, which has been converted from its original guitar-synth form to basically be an Odyssey without keys (but with the addition of a very cool fuzz mode!). It sounds absolutely amazing, and is a very unusual instrument. It's controlled via CV. I'll throw in an Arturia Beatstep and some cables to get you started."

Synth Chaser Serviced Vintage ARP Omni 2 Analog Synthesizer Keyboard

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

via this auction, also on Reverb

"This synthesizer has just been fully serviced by Synthchaser, the leading ARP specialist - recapped, new key bushings, sliders disassembled and refurbished, clean, fully functional, calibrated, in tune and sounding great. This keyboard is the sound of Joy Division and is all over The Cars' "Moving In Stereo", and many other late 70's/early 80's albums. It produces the lush Solina/String Ensemble sounds plus has a polyphonic synthesizer section with a voltage controlled filter, LFO, and ADSR, and a dedicated bass synthesizer section.

Good condition, scratches on the top as is common for these, see photos. This is an early model Omni 2 with the black buttons, power indicator LED, enameled ARP badge, and wood side panels. Left panel has some red sticker/tape residue on it and a chip on the bottom. See photos for condition.

Sliders refurbished - It's rare that Synthchaser will agree to restore the original sliders in these synthesizers, but when he does, he does it right! The sliders have been desoldered, disassembled, ultrasonically cleaned, lubricated, reassembled, tested and reinstalled. All original slider caps are present!
Power supply rebuilt - All tantalum and electrolytic capacitors in the power supply have been replaced, and high quality, high temperature 105 deg C capacitors have been used for the power supply filter capacitors.
All tantalum capacitors replaced - The tantalum capacitors in ARP synths are ticking time bombs. All of the over 100 tantalum capacitors in this synth, including the power supply and filter submodule, have been replaced with electrolytics to help provide stable operation for years to come.
Synthchaser 4075 Filter Enhancement Kit Installed - The ARP Omni uses the same 4075 filter submodule found in the Odyssey, Quadra, Avatar, and Pro DGX. This has been recapped, and enhanced to provide superior frequency response.
Keyboard rebuild - New key bushings installed, buss bar & key contacts cleaned and adjusted, keybed leveled, keys ultrasonically cleaned
Oscilloscope calibration - Fully calibrated to factory spec using oscilloscope and frequency counter."

Restored Vintage ARP Quadra Synthesizer Keyboard with MIDI

"This ARP Quadra has just been professionally overhauled by Synthchaser, the foremost expert on ARP Quadras! Work done included new orange LED sliders (illumination can be disabled before shipping at buyer's request), recap of all tantalum and electrolytic capacitors, new touch sensor, keyboard refurbishment, new IC chips, reliability enhancements, and perhaps most unique of all... this may be the world's first ARP Quadra with MIDI!

While many synths are listed as "serviced" or "fully serviced", they are usually devoid of any details of what was actually done. Those that do provide details or service invoices often reveal that the synth was merely superficially serviced, and not genuinely "future-proofed". I have not only serviced this Quadra, I've taken it down to the chassis and overhauled it. Work done included:

Has a some scratches on the case, which is common to these synths, see photos. However, the keyboard sounds great and has been completely overhauled inside with hundreds of dollars of new parts and many of hours of labor, including:

Synthchaser Precision LED slider upgrade. All 15 of the old original sliders have been replaced with new, smooth, high precision LED illuminated sliders. The difference in the way these sliders feel and perform compared to the originals is a huge improvement. The LED colors match the color scheme of the panel graphics.

Illuminated slider caps - Slider caps with a translucent plastic stripe that allows the LED illumination to shine through, while giving you something substantial to grip onto. I just started using these caps, and they look and feel awesome!

Synthchaser replacement pushbutton switches - All 10 of the original pushbutton switches (which are notorious for having the mechanical latches break) have been replaced with retrofits. The original switch caps are still installed so they look the same from the outside.

Power supply rebuilt - All tantalum and electrolytic capacitors in the power supply have been replaced, and high quality, high temperature 105 deg C capacitors have been used for the power supply filter capacitors.

Ex-Jefferson Starship ARP Quadra Synthesizer Serviced w/LED Sliders New Membrane

via this auction

"This ARP Quadra was owned by Pete Sears and toured with Jefferson Starship in the 1980s! It has just been professionally overhauled by Synthchaser, the foremost expert on ARP Quadras! Work done included a new membrane panel, new blue LED sliders, recap of all tantalum and electrolytic capacitors, new touch sensor, keyboard rebuild, dozens of new IC chips, and more!

While many synths are listed as "serviced" or "fully serviced", they are usually devoid of any details of what was actually done. Those that do provide details or service invoices often reveal that the synth was merely superficially serviced, and not genuinely "future-proofed". I have not only serviced this Quadra, I've taken it down to the chassis and overhauled it. Work done included:

New membrane panel - The membrane panel with the switches that enable the various features and pull up the presets is a known weak spot of the ARP Quadra, and many otherwise good Quadras have been turned into expensive doorstops due to failed membrane panels. A brand new (manufactured in 2020!) Synthchaser membrane panel has been installed. It looks just like the original! Have other "future-proofed" Quadras had this part replaced? I think not!

Synthchaser Precision LED slider upgrade. All 35 of the old original sliders have been replaced with new, smooth, high precision LED illuminated sliders. The difference in the way these sliders feel and perform compared to the originals is a huge improvement.

"Works great. Obvious wear and tear from its birth in 1977. Some sliders are missing the little plastic caps. Works awesome when paired with a modular system via cv and gate ins / outs. Awesome for guitar players with the guitar pickup (sold separate). Comes with power cable . Fun synth!"

Arp Avatar - Modularized by CMS

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

via this auction

"Letting go of this Arp Avatar which was “modularized” by Phil Cirocco at CMS in 1995. Only 300 of the original units were produced, so I’m assuming the number of “modular” Avatars is less than that, although they they pop-up occasionally. I’m trying to scale down my studio and this synth is literally the biggest obstacle in this goal.

This is what it has:
It has many features of the Arp Odyssey: Two oscillators, and features such as oscillator sync, ring modulator, sample and hold, portamento, envelope follower and more. It is almost identical programming and interface. I read somewhere that the added patch points supposedly give the modded Avatar approximately 75% of the functionality of an Arp2600, but I really can’t say for sure.

Polyphony - Monophonic
Oscillators - 2 VCOs: Sawtooth, Square, Pulse
LFO - Sine, Square
Filter - Model 4075 4-pole, 24dB Low Pass Filter
VCA - Env 1: ADSR, Env 2: AR
Keyboard - None
Memory - None
Control - CV / Gate
Date Produced - 1977 - 78

This is what it doesn’t have:
- The top of the slider for String CV. It got broken off. The slider works but it’s tricky to move. See photos. It could be hacked with a fader cap or something. The ideal would be to replace the fader and those can be found fairly easily.
- The guitar synth functionality. The work done by CMS neutralized the Avatar’s guitar synth circuits. If this feature is important to you, this is not the Avatar you want.
- It does not have MIDI. The Avatar was produced in 1977/78 and MIDI didn’t come around until 1983, so you’ll need an MIDI to CV converter or a MIDI synth that has CV/Gate outputs. I triggered it via Doepfer MAQ 16/3 or a Roland MPU-101."
