ARP Omni-2 with Aftertouch + S&H Mod

Note: Auction links are affiliate links for which the site may be compensated.
video upload by New England Analog Archives

Note this demo is from 7 years ago.

"This video features an ARP Omni 2 synthesizer that has been modified with a custom LFO expander daughterboard. The PCB comes assembled and measures 2.7 x 3.2 cm.
This upgrade is simple to install, and it provides the LFO with 2 additional waveforms. A 3-position toggle switch controls the waveform selection. An adhesive-backed overlay decal is provided with the kit. The switch will allow sine, square, and random LFO waveforms to be selected. Kit includes instructions for expanding the range of Omni 2 VCF so that it can self-oscillate. This modification greatly expands the sonic possibilities of the ARP Omni. This kit will work on ARP Omni 1 as well. It can also be used to add an auxiliary sample and hold waveform to ARP Axxe, Odyssey, and Quadra LFOs."

"The unit has been well maintained and has had the following work/mods done:

Replaced the noisy ARP power supply with a Power One linear supply

Unit was completely recapped in 2015.

All analog ICs and digital ICs were replaced

All sliders removed and restored. All now move smoothly.

Slider caps replaced with new ones.

Pratt Read keyboard bushings replaced in 2015.

Aftertouch added to the keyboard.

Aftertouch amount is routed to the ACC/PEDAL slider. The aftertouch affects the VCF cutoff. Additional waveforms added to the LFO. Originally only had sine LFO. Added square and sample & hold LFO. Sample & hold is the same circuit as ARP Odyssey MK1 S&H. Sounds great. 4075 VCF module recapped and had the cutoff frequency design error corrected. (Originally there was a design error, keeping the cutoff from fully opening up)

The finish on this Omni is not pristine. When I got it, it had been neglected for years after being in storage. Cosmetically, this is a 6/10 as there is evidence of lots of use on the powder coating.

I've attached a video deomonstrating the LFO mod I did to this Omni. The unit in the video is actually this Omni, but I have since removed the LED sliders, since I thought they were annoying."

ARP Pro-Soloist Monophonic Analog Synthesizer SN 173865

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


via this listing

"Rare ARP Pro Soloist Restored by Custom Vintage Keyboards in Los Angeles. Nothing else sounds like it.

Even after restoration, this synth is fragile, temperamental and needs a long warm up, so should only be used in the studio. The original flimsy particleboard bottom has been replaced with a real wood one and all the aftertouch has been gone through and feels excellent. A previous owner scratched some letters near the output jack, and one of the end cheeks has a square mark from a sticker, but otherwise this is in good cosmetic condition."

Korg SR-120 Analog Drum Machine One-of-A-Kind PROTOTYPE Made in Japan

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


via this listing

"This is the original, one-of-kind prototype for an upgraded version of the Korg SR-120 analog drum machine. An engineer decided that the tempo dial on the SR-120 was too limited with regard to the beats per minute choices, so he designed this prototype, employing a dual-dial configuration, which gives the user infinitesimally more control over the BPM. While well-received by the Korg creative team, the suits decided that the production costs would be too high. It remains a singular gem.

The machine is contained in a super-protective case that makes it highly portable. You simply unlatch the top to expose the unit’s panel. It’s in superb condition and perfect working order."

It is all in great condition save for a broken toggle shaft/arm on the “Sweep Up” lever. Lever still functions and would probably be easily remedied with a replacement plastic rod and some super glue. I will leave that to the new owner. (see pics)"

Completely Overhauled Original Lyricon Wind Synthesizer

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


via this listing

"classic, early 1970s Lyricon I analog wind synthesizer made by Computone, in the USA.

It was completely overhauled ($850) less than two years ago and everything works perfectly.

This is an analog synth that is keyed for sax, clarinet, and flute players, offering an extra set of sound dynamics through the mouthpiece.

You do need to experiment with the controls; the manual explains how to get started, and then you have a wide range of analog controls to work through to create sounds. There is no storage of sounds.

Comes as pictured, including a photocopy of the manual, original document, and an original magazine advertisement."

The Human Comparator 73-75 Serge Homebuilt w/ Custom Expander

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


via this listing

"This instrument is tons of fun, and also is a seriously customised build. I bought this kit years ago and have been slowly assembling it. It works in full, and unlike many specimen out there, is very compact while being equipped with a spring reverb tank. I recorded two albums on it in its unfinished state, then had it dust up for a bit, but now it's fully finished.

It received the following customisations:

A halfpanel expander (the black strip) has a DC offset generator, noise source, inverter and an output summator - 3.5mm mono output on the right side. This expander implements some functions that are not there or will save you an entire voltage processor half.
As a finishing touch, there's a fully powered breadboard for you to try out some stuff on. It has +-12v and ground broken out to it, so active circuitry is a possibility.
I built a custom linear power supply for it - its regulators are short-circuit protected, so the breadboard is somewhat foolproof.
There's a long ass bank of decoupling capacitors on the lower panel, ensuring smooth and quiet operation. So far it has been remarkably fine, and has greatly reduced the voltage processor bleedthrough that many people on the 73-75 group have experienced.
The reverb and preamp circuits have been replaced by entirely custom circuitry attached to the upper panel; the original ones were too noisy for my liking.
The jack color scheme is a standard Serge one instead of the THC-proposed faded old-styler colouring
The 3.5mm~banana converter banana jacks output ground if the 3.5mm part is not used, making them ground references.
Will ship more or less anywhere via Estonian standard post double-boxed and with tons of filler; other carriers = add'l cash. I will throw in some shorter banana cables, too. This unit runs on 15v AC (not DC!) - i can help figuring out a suitable brick for you to buy in place, as mine is european standard and my only one, so i'd like to keep it.

My camera is not of best quality, so a hi-res reference can be found on the kit producer's website (73-75.com) to see which exact modules are there."
