ARP 2500 Modular Synthesizer w/ Pair of Fully Loaded Wing Cabinets

This one was spotted and sent in via
M Me.

"Vintage ARP 2500 Modular Synthesizer system. Accompanying the ARP 2500 main cabinet is a pair of fully loaded wing cabinets. The main cabinet and keyboard were fully restored by Phil Cirocco (CMS) around 2011 as well were most of the modules in the wing cabinets. However the system has not been powered up or played since 2018 when I moved from Los Angeles to Tucson Arizona. It was working perfectly in 2018. Since sitting for 7 years the system will most likely need some small service to get it back to perfect. IT IS UNTESTED AND WILL NOT BE TESTED. IT IS BEING SOLD AS IS.

The previous service was meticulously done to satisfy my serious demand for the system to remain as original as possible. No modifications were done and all parts replaced with original or appropriate parts. The system is hyper clean in person and was clearly babied. It was used on notable lp's. You may live a 100 more years but will likely never find a better more complete ARP 2500 for sale. This system is priceless and was the most expensive new instrument when it was produced in the early 1970's.

I collected and played many Moog, ARP and Buchla modular systems. However owning so many systems became a burden. As well, switching between using Moog, ARP and Buchla took too much bandwidth. I sold all of my Buchla systems and this is my last and best ARP piece from my massive collection. Time for someone else to own it

CAN BE PICKED UP IN TUCSON AZ OR I CAN DELIVER TO LOS ANGELES CA"

Analogue Solutions Introduces the TC5000 - ARP 2500 Inspired Synthesizer

video upload by sonicstate

"Tom's stand is hard to miss, always something massive and/or impressive to catch your attention ;-]

This year it's the turn of the TC5000, a synthesizer drawing inspiration from the ARP2500 with a patch matrix system along the lines of those he has developed since the Vostok. The TC5000 has a unique mix of circuits - compiled from years of development in products like the Fusebox and Colossus - and its user interface, for ease of patching across upper and lower matrices.

With a host of modules, including oscillators, filters, sequencers, and dual spring reverbs, Tom plans to provide a comprehensive package, with potential expansions through additional "wings" or systems.

Price is expected to be in the £22K range, available towards the end of the year"

"ANALOGUE PATCH PIN MATRIX SYNTH

This product is so new, we haven’t even finished this web page!

The selection of modules that will be configured in the final system will differ from the pre-production unit features in the current photographs.

WE ARE TAKING PRE-ORDERS NOW (DEPOSIT REQUIRED).
ETA TOWARDS THE END OF THE YEAR.

This is not an ARP2500 clone! TC5000 ustilises Analogue Solutions’ own circuits. Some are adapted from our other stunning synthesizers, like Leipzig, Telemark and Fusebox. Plus some new designs especially for this synthesizer.

TC5000 features two full width patch pin matrix panels that provide the same kind of UI experience that made the ARP2500 so incredible.

Using TC5000 for sounds design will give you a similar experience to the ARP. User interface is a very important aspect of sound design. It really isn’t all about the filter. How you interact with a synth is equally important. Different UI and working approaches means you will come up with patches you might otherwise not have come across using say, patch leads."

"EXPERIMENTAL ELECTRONIC MUSIC EXPERIENCE" - PIOTR GARBACZONEK (FULL LIVE PERFORMANCE AT BERKLEE)

video upload by Piotr Garbaczonek

"Thank you all so much for watching my performance!
Date: December 14th, 2021
Location: B54 at Berklee College Of Music, EPD Labs
(Electronic Production and Design)

This show was my showcase as part of my EP-491's final project for my major. Aside from finishing a 5-track EP in a semester, I also was preparing this set for a very long time along with all the music. I decided to pull in a few songs from my previous EP: Experimental EP, Vol. 01, to spice up the performance a bit. The songs included were: Conformity, as the first song after the modular-only section; Time, which was the song at the end of the set with the QR code to my social media links. Everything else was songs from the past 4 months.

All the visuals were edited beat by beat, a song by song in Adobe Premiere Pro, and then rendered and then put into an Ableton Session to be played in a specific earlier-defined order.

I divided the show into 2 sections: Ambient Experimental, and Glitch Experimental.

The first part included rhythm-free elements only and primarily played on various modular synths, up until the 13th minute, where modular synths were supporting all the songs played in order.

The second part included various drum elements, as well as glitch music and frequency spectrum bending polyrhythms.

In terms of gear used, I used my Zoom L-12 Multitrack Mixer, to record all of the individual inputs directly into Ableton. Ableton had different effects in the effects chain of each track depending on what was necessary for each one.

For all the weird clock-driven, laser-sounding fast atonal sounds, I used the CMS MR-15 Modular System based off of the ARP 2500. For some chords and mild sawtooth progressions, I used the Blue Marvin 2600, which is based on the ARP 2600 with built-in Spring Reverb. The Blue Marvin was sequenced by one of my Qu-Bit Bloom Sequencers running in the minor key.
The master clock for everything was the ALM Pamela's New Workout, and it was clocking the CMS, Blue Marvin, 2x Qu-Bit Bloom, Qu-Bit Chance, Moog Subharmonicon (which was doing all the background pads), and Mutable Instruments Rings.
There were various other sequenced sounds, including Mutable Instruments Plaits as a 32-step arpeggio in minor, as well as Mutable Instruments Rings, going through Clouds as a textured effect.
Cwejman VCO-2RM was running through Qu-Bit Tone's LPF, and directly out as a very low analog sub.
The E340 Cloud Generator was my analog Wavetable synth, which I played directly on the Arturia Keystep MIDI-Controller, by sending it pitch information only, and running it through MI Ripples, and out.
The Instruo Arbhar was running in stereo mode, and that one was doing all of the tapping and scratching noises in left and right channels. It has a built-in condenser mic, so I was tapping it on the spot to fill up some space in transitions for some ASMR effects haha.
That's pretty much it in terms of gear used.
If you have any questions about anything, please don't hesitate to ask in the comments. I will happily answer.

Again a huge thank you to Wiggz for doing some cool action shots while I was playing.
This is his YouTube channel: https://www.youtube.com/channel/UCItL...

And thank you to Dr.B for being an amazing professor, and leading me through the last stretch of my EPD Journey, as well as opening new doors for me for the future.

"Thanks for watching!

EXTREMELY RARE!!! C.M.S. MR-15 ModRack Modular System at Berklee (Piece showing its possibilities) Every sound in this piece was recorded using the C.M.S. MR-15 ModRack Modular System, including drums and bass. It is not a performance, I recorded individual layers using different patches and only recorded one layer performed. All the other videos you see are of different patches as well as angles of this beautiful synth for your viewing pleasure.

If you want to find out more about the maker of the synth as well as his company, I will have both listed below. Phil's instruments are crafted with utmost precision, and it was so much fun to be able to use it for a few hours.

Vintage ARP Odyssey 1972 Mk. I + Full Patch Points + Cirocco Mods!

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

via this auction

"Arp Odyssey Mk. I 1972, full patch points + Cirocco (C.M.S.) mods

Mods too many to list, but include (highlights):
Full patch points -- all main section outputs and all slider inputs
"Turbo" envelope switch, for true snappy (2600 style) envelopes
LFO free run
Back panel CV/gate controls
External audio input
A full set of mods can be seen from the picture. Mods were performed by #1 worldwide Arp tech Phil Cirocco (the guy who fixes/restores 2500's).

I should mention that another design quirk of the original Odyssey -- the delay between VCA and VCF gate times, has been eliminated!

Without this critical fix, no matter how fast the envelope times, it would have sounded slow due to the VCF gate delay. Not so here, the envelope is ultra-fast with the "Turbo" setting, and also sounds better and cleaner with the normal setting. This is what is meant by "true 2600 style envelopes" -- multiple coordinated modifications here really take this synth into a completely different category.

What you get is the 'best of both worlds'. You get additional features and sound of the early 1970's Mk. I Odyssey (much warmer early 1970’s oscillators, sweet filter resonance, hard sync), with the back-end snappiness and sonic character of the Arp 2600. On many patches the result actually sounds better than the stock 2600."

An ARP 2500 in Eurorack Format?

CMS 1004 demo - The Pearlman Oscillator and T-mixer Published on Sep 24, 2018 Phil Cirocco

"This is a quick preliminary demo of the new CMS 1004 Pearlman Oscillator. This VCO is a faithful reproduction of the massive VCO circuit from the ARP 2500, shrunk down to euro rack format. An analog CRT oscilloscope shows some of the unique and interesting waveform combinations available. discretesynthesizers.com"

CMS is going eurorack with the CMS 1004T (ARP 2500) - Pearlman Oscillator and T-mixer

This is huge news. Not only the ARP 2500 1004T oscillator in eurorack format, but CMS entering the eurorack market as well. Phil Cirocco of CMS is known as the ARP specialist in the US. He works on vintage ARPs as well as designing his own synths, most recently the CMS 2607. Be sure to see the CMS label at the bottom of this post for more.

Pearlman, of course refers to ARP's founder Alan R. Pearlman.

Curious if CMS plans a full blown ARP 2500 in eurorack format. Imagine that. :)

CMS 2607 music video, interesting ARP photos

Published on Oct 27, 2016 Phil Cirocco

"This is a promotional video for the CMS 2607 synthesizer. There are also some interesting and rare photos of some landmark ARP instruments and some significant CMS 2500 restorations. The music is a live stereo mix of the sequence I am presently having fun with. Phil Cirocco"

Introducing THE CMS 2607 - An ARP 2600 on Steroids

As you know, CMS (Cirocco Music Systems) is Phil Cirocco's synth company. He is not only the world's most renown ARP tech (BTW, see my CMS Lumina upgraded Odyssey here!), but also a manufacturer. THE CMS 2607 is his latest creation. Knowing it comes from him, you know this is going to be one great synth.

The following are some details via CMS:

"THE CMS 2607 6U RACK MOUNT INTEGRATED SYNTHESIZER

CMS is proud to unveil for the first time, our new synthesizer, the CMS 2607. We took all the features of the original ARP 2600, combined them with our world famous upgrades, added more cool stuff and then squeezed it all into a 6 space rack mount heavy duty enclosure. This particular incarnation is the '2500 version' that features a beautiful heavy duty brushed aluminum front panel. We are also currently making standard versions using grey and blue paint similar to the original ARP 2600 factory color schemes.

Initially, a very small quantity of special issue handmade 2607s will be made available to the general public until the factory produced models are available. These will be priced higher than the factory made mass produced units.

Price for one of the hand-made limited edition $8699.00. (9,499.00 for units with early type VCOs) plus packing and shipping charges.

Target price for the standard version 2607 will be 4999.00 USD . The standard version is not available at this time but we will soon be taking orders on the standard version. This price is subject to change. Check back with this page if you are interested in the standard version and can wait.

If you are interested in ordering one of the special issue limited edition 2607s now, send a paypal deposit of $3000.00 USD to filter@discretesynthesizers.com to register your order or mail us a personal check. Delivery guaranteed to be no longer than 4 months from the date of deposit. There is a limit on how many of these special order units that will be available for 2016, so contact us now if you are seriously interested.."

ARP Odyssey 2800 with CMS Lumina Upgrade & Raggedy Ann for Christmas

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

via this auction

I don't think Raggedy Ann comes with the listing.  She looks happy though.

"This auction is for an ARP Odyssey model 2800 in very good condition that has been recently restored to ARP factory specs by Phil Cirocco at CMS / Discrete Synthesizers. It features the Lumina slider upgrade (special 4 color edition), just in time to brighten up the under-tree display on Christmas morning! Here is the complete List: Lumina Slider Upgrade - special 4 color edition – see photos 34 high quality illuminated slide pots. The main focus of this upgrade is to install high quality sliders in an ARP Odyssey. The Odyssey and Avatar have similar circuitry to the 2600, however they used cheap, unreliable, plastic on plastic sliders. These brand new, high quality sliders from CMS feature a superior tactile feel and greatly improved accuracy. It basically transforms an unreliable old doorstop into a precision instrument, on par with the ARP 2600 and ARP 2500. The difference in reliability and accuracy is astonishing! The upgrade also features a blinking LFO slider indicating the LFO rate. The ADSR and AR sliders now feature dynamic LED readout of the envelope generator voltage levels. All Keyboard rubber bushings replaced with new and keyboard detailing. All key contacts cleaned and adjusted. Power supply rebuilt to factory. Separate power supply for slider LEDs. Audio Path Upgrade. Highpass filter bypass switch – Adds sub-bass to the output signal. LFO free run switch. ADSR time range switch – 3 position toggle features extra long time mode.

1976 ARP 2600 with Original Leather Cases & ARP's Old Number

Note: Auction links are affiliate links for which the site may be compensated.
Published on Dec 14, 2012 by MechHandlingSystems

via this auction

"Along with the owner's manual and Patch Book, it has a copy of a 2-page hand-written note detailing setup, trim, VCO and VCF calibration and keyboard calibration. The best part of this is the sloppy market notation at the bottom of page 2,

"IF YOU GET IN TROUBLE, CALL:
CLARK FERGUSON OR PHILIP DODDS
965-9700"

Clark Ferguson was ARP's service department manager, and Philip Dodds was VP of engineering. These notes are likely written in Philip Dodds' hand. He was an interesting guy that ended up having a featured role in "Close Encounters of the Third Kind" after Spielberg saw him setting up a 2500 to do the big "dum dum dum DUM DAAAAA" thing.

MECHANICS

It is the 2601 V1.0, with the improved jacks that won't flake out and the better sliders. It is the most mechanically advanced ARP 2600 model that still contains the legendary 4012 ladder-type filter that was built too close to Moog's patents for their comfort (an actual lawsuit was never filed)

It comes with the duo phonic 3620 keyboard. Serial numbers match and are in the low 300s.

There is a broken slider at the bottom center of the main panel, although it works and can be adjusted by hand. I am looking for the replacement slider and knob I purchased and hope to include it in the auction. See pictures for detail.

A few of the sliders have scratch. See the video for an example of that.

ELECTRONICS

As just mentioned, it has the 4012 filter. Now, some of these are epoxied and gross. Some of them are copper clad but with sloppy brazing. But some … well, some glow like a beating heart pumping astounding signals through its soldered veins and arteries. This one is like that.

It also has the UN-encapsulated 4027-1 VCOs, which are necessary if you plan to do certain mods.

It also has a mod for a Mediamix Joystick, which I just learned thanks to Phil at CMS and have never looked for one. I have a picture of one for the winner. Owning a Synthi AK I can tell you joysticks are pretty nice to have on your synthesizer!

The capacitors on the power supply are 35 years old and should be replaced soon, according to a bunch of people that seem to feel very strongly about it. CMS sells a power supply you can install yourself, if you're into that kind of thing, for $169."

ARP 2500 modular synthesizer

via this auction
"Rare, early ARP 2500 modular synthesizer in very good cosmetic condition and working 100%. A friend of mine bought this one from Phil Cirocco of CMS/Discrete Synthesizers in late 2007 and it's still working solid. As you can see, this is an earlier 2002 cabinet with a 3000 series keyboard.

It includes the following modules-
1002 Power Control
1003 Dual Envelope Generator
1004T VCO
1005 Ring Mod / VCA
1006 Lowpass filter / VCA
1016 Noise / Random Voltage
1023 Dual VCO
1027 3 x 10 Sequencer
1033 Dual EG with delay
1036 Dual S/H, Clock
1047 Multimode Filter"

Cosmetically- The veneer on the cabinet does have some chipping here and there, but overall it still looks very good. Some of the modules have a former owners name and the serial # etched in on the corners.

Internally- According to Phil's description when he sold it, the power supply had been upgraded about 2 years prior to my friend buying it to a 1.5 Amp, low noise high performance unit. The separate 12v lamp power supply had also been rebuilt around that time.

The keyboard works great as well as all of the knobs, switches, matrix sliders, etc. No scratchy pots whatsoever! Phil obviously took care of this thing. I did notice that one of the LEDs on the sequencer has since burned out, but if this is an issue I can have it replaced.

This is not a plug in and play unit like an Arp 2600. Patching is required if you want sound. Please be aware of this."
