Due to unforeseen circumstances I’m selling my brand new( just several weeks old) hand made Mos Lab system. Price reflects what I paid for it minus the shipping cost and import duties. Not looking to make a profit on this.
Only 30 cabinets were made and these are the last two."
"The Moog modular was one of the first commercially available synthesizers. Sold in different configurations, the Moog IIIP consisted of 3 portable cabinets. Containing ten (!) 901 series oscillators, the best lowpass and highpass filters in the biz, and a magical spring reverb that makes things sound more organic, we can't think of any other synth that matches the warmth and fatness of this genuine 1969 vintage Moog modular. Wendy Carlos’s classic album Switched on Bach and I Feel Love by Donna Summer were recorded on similar Moog modular systems. We just finished refurbishing this gorgeous example (assuming we don’t find any problems as we continue to test it). Restoration was done in stages and took many months to complete. Total tech time spent was around 85 hours. We hit a snag when some parts we ordered turned out to be fakes - a sadly common occurrence these days - but we eventually managed to track down some legit replacements. We originally planned to sell this system, but after spending some time patching it, we don’t know if we can let this one go! If this system was set up in a commercial studio here in New York City where it was available for use, would you be interested? If so, please email us. Or, make us a serious offer and if it's tempting enough, maybe we'll sell it. We'd also consider trades for similar vintage modular systems (Roland System 700, Buchla 200, Polyfusion, Emu Modular, ARP 2500, etc). We have a smaller (single cabinet) real vintage Moog Model 15 that's ready for sale.
We buy sell trade refurbish vintage synths and electronic musical instruments.

ALAN R. PEARLMAN FOUNDATION ANNOUNCES INAUGURAL CELEBRATION OF THE CENTENNIAL BIRTHDAY OF ARP SYNTHESIZER FOUNDER, ALAN R. PEARLMAN, JUNE 7 AT THE MUSEUM OF MUSIC TECHNOLOGY
Kingston, NY - May 20, 2025 - This year marks the 100th birthday of the late inventor of the ARP synthesizer, Alan R. Pearlman. In honor of his pioneering innovations in electronic music, the Alan R. Pearlman Foundation will launch ARP@100: A Centennial Celebration of Alan R. Pearlman’s Legacy with EMEAPP at the Museum of Music Technology. A gala event kicks off a year’s worth of commemorative ARP centennial activities and takes place at EMEAPP, located in Harleysville, Pennsylvania, from 7 -10 pm.
June 7th Centennial activities at the museum include:
A live interview with the ARP Foundation’s director, Dina Pearlman-Ifil
Video excerpts from musicians, former ARP employees, and filmmaker Alex Ball’s celebrated ARP films
Performances on vintage ARP instruments by music pioneer Don Slepian and modular synthesist Ombient
The ability to try out a variety of synths
EMEAPP will unveil, at its Museum of Music Technology, a haven of vintage ARP history in which visitors will encounter an epic collection of ARP synthesizers, including the majestic ARP 2500 and a rare, early ARP 2502 with a cherry drop matrix. The iconic ARP 2600 Blue Meanie will be proudly displayed alongside an array of other ARP classics: the versatile Quadra, the expressive Soloist series, multiple iterations of the legendary Odyssey, the innovative Avatar, the powerful Chroma, the punchy Axxe, the compact Little Brother, and even a remarkable 16-Voice Electronic Piano – many of which will be playable!
Countless composers, musicians, and filmmakers worldwide have incorporated the ARP 2500 and ARP 2600 into their work, including early adopters Pete Townsend (in the “Who’s Next” album) and Elton John (in “Funeral for a Friend”). Stevie Wonder, an early adopter of the 2600, had his control panels labeled in Braille. The ARP 2600 was also responsible for the voice of R2-D2 in Star Wars films, and the 2500 was used to communicate with aliens in Close Encounters of the Third Kind.
Alan R. Pearlman’s legacy as an engineer and inventor began at an early age. A fascination with sound occupied his interest, and he spent time as a child building amateur radios. In 1948, as a student at Worcester Polytechnic Institute, he wrote, “The electronic instrument’s value is chiefly as a novelty. With greater attention on the part of the engineer to the needs of the musician, the day may not be too remote when the electronic instrument may take its place as a versatile, powerful, and expressive instrument.”
Attendees may reserve a spot at this exclusive celebration and fundraising event with a tax-deductible donation of $150 per ticket. The contribution includes complimentary wine/beer/other beverages, a selection of snacks, and a swag bag. Parking is Free.
The Museum of Music Technology/EMEAPP is located at 45 Mainland Road, Harleysville, PA 19438, just a short drive from the PA Turnpike Lansdale exits."
"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"

48:26 Conclusion
Oberheim Legacy: In 1974, Tom Oberheim imagined a small synth as an accessory to his DS-2A digital sequencer. But it was Dennis P Collins, a gifted ARP engineer, who designed the multimode filter of the Synth Expander Module (SEM). This unique filter is a 12 db filter that cannot deny its lineage with the ARP 1047 (ARP 2500) and ARP 2023 (white Odyssey MK1) filters, 12 db filters also designed by Dennis P Collins. With two very fat VCOs and a devastating sync (also close to the Odyssey VCOs), the small SEM offers a powerful sound, very present in the mix and very different from Moog and other synths with 24 db filters. So despite its simplicity and a filter that does not enter self-oscillation, we can get a lot of sounds out of it. Accessible and easy to use, the SEM is a success. In 1975, Tom paired first two, then four, into a huge keyboard case, creating the first "true" polyphonic instrument in history, the "Four Voices." In 1976, the SEM was even expanded to eight. Nicknamed the "White Elephant," its sound was as enormous as the instrument itself! But in 1978, the brilliant Prophet-5 made it obsolete, and Tom designed the OB-X, whose channel cards were also clones of the SEM. Subsequently, the OB-XA and OB-8 used Curtis chipsets and no longer had quite the same sound. In 2010, Oberheim reissued the SEM identically, but with all surface-mount components. In 2011, the SEM PRO added just a MIDI interface.
NRsynth "Solo": This is an "extended" version of the SEM, handcrafted with traditional through-hole components. Only the envelopes have been modified for a punchier result; the rest is identical to the original synth. Additionally, the Solo features a sub-oscillator, a glide, white noise, and many more modulation options than the SEM. MIDI velocity is also supported. Finally, the white metal case gives way to a luxurious, classically crafted cabinet with waxed oak sides and black tolex, similar to a Marshall amp.
VCO: Two discrete VCOs with hard sync, saw, pulse + PW (same as SEM)
Sub-oscillator: Pulse wave – 1 octave below VCO1.
Noise: 100% analog white noise
Multimode 12 dB filter: Same as SEM with LPF, HPF, notch, and bandpass mode. VCA: Analog (same as SEM)
LFO: Analog, triangle wave (same as SEM)
Envelopes: Analog (same as Pro-1) with deactivatable "Release".
Digital LFO: 8 waveforms + tilt, 3 frequency ranges, sync.
Sample and Hold: Analog, sync.
Glide: Analog portamento circuit at the input.
Patchbay: 15 I/O points on 3.5mm jacks (Eurorack compatible).
Rear Connections: Audio I/O and sync on 6.35mm jacks. Reset button.
Dimensions: 30x24x15 cm
"Alan R Pearlman was responsible for some of the greatest sounding and most intuitive synthesizers of the modern age, many of which are still highly sought after or emulated to this day. Inspired, as so many were, by hearing Wendy Carlos’s 'Switched on Bach', he founded Tonus in 1969, a company that would soon become ARP Instruments, and began producing synthesizers such as the legendary ARP 2500, 2600 and Odyssey.
Since his passing in 2019 at the age of 93, his daughter, Dina, has been building the Alan R Pearlman Foundation, an organisation that seeks to preserve her father’s legacy and enable as many people as possible to get hands-on with his inventions.
As with all not-for-profits, Dina has faced numerous challenges, but with the help of the likes of Jean Michel Jarre, Herbie Hancock and many other fans of Alan’s work, the Foundation is beginning to realise its objectives with great success.

Dina Pearlman Biog
Dina is the only child of Alan and Buena Pearlman and grew up with ARP Synthesizers as a backdrop for her childhood, travelling extensively and being exposed to innovative and cutting-edge technology. In her early years, she spent time playing in rock and roll bands, as well as dance and theatre. For the past thirty years, she has worked as a versatile visual arts and design professional, creative director, and educator. She has also worked extensively in photography, graphics and web design for several decades, and has a broad understanding of visual communications media.
In the last few years before his illness, Alan Pearlman started to re-examine the brave new world of synthesizers that exists today, many decades after his iconic and groundbreaking 12 years as the inventor and founder of ARP Synthesizers. During this time, he brought his daughter into the conversation. After his death in January 2019, Dina realised the need of keeping his legacy and passion alive, and with the help and encouragement of many of his former colleagues as well as the wonderful Michelle Moog-Koussa, she started the Alan R. Pearlman Foundation and ARP Archives.
ALAN R. PEARLMAN FOUNDATION ANNOUNCES NEW BOARD MEMBER
The ARP Foundation Continues to Strengthen its Mission
Kingston, NY, JANUARY 24, 2025 – The Alan R. Pearlman Foundation has welcomed a new appointee to its Board of Directors: Stephen DeJesus
Stephen DeJesus is a professional engineer and long time synthesizer enthusiast located in Boston, MA. First introduced to synthesizers in a tiny electronic music studio at Boston University in the 80's, the Arp 2500 and Arp 2600 synthesizers encountered there launched a lifelong interest in performing and producing electronic music on a broad assortment of synthesizers. Current musical efforts are focused on sequenced and generative music created on modular synthesizers in the Eurorack environment. Steve is an active participant and performer in the Boston synth community and volunteers his time for the ARP Foundation as the local curator for the Arps For All program, providing unprecedented public access to vintage ARP synthesizers, including the recently acquired ARP 2500.
"We’re very excited to welcome this talented professional into our Board of Directors," said Dina Pearlman-Ifil, founder and Executive Director of the ARP Foundation and daughter of Alan R. Pearlman. "Stephen has been working boots on the ground at our project ARPs for All at Boston’s TRC, and has been invaluable in working with our educational resources”
The ARP Foundation continues its work with contributors, collaborators, vendors, manufacturers, venues, and synthesizer owners to provide music students with access to vintage ARP synthesizers to explore the endless possibilities of electronic music. The Foundation relies on donors to continue its mission, and encourages everyyone who understands the importance of music education to visit www.alanrpearlmanfoundation.com to learn more and pledge their support.
"What a fantastic year! From our ARP 2500 wing cabinet coming to Boston, to Stevie Wonder, Pete Townshend, Patrick Moraz, Jon Batiste, Greg Phillinganes and Anthony Marinelli playing and displaying ARPs for the world to see. We have summarized all of it in this video... music by the immensely talented Chicago musician Rick Reger, used with his permission.
Thank you to all of our supporters, partners, volunteers, sponsors, friends and donors. We are literally nothing without you and. your ARP Love. A Very Happy New Year!
This video examines the AMSynths AM1031 Multipurpose Filter. This state variable filter was created by Dennis Collin who also created the ARP 1047 Multimode Filter. The two filters are similar, but the 1031 includes an addition response called Peak.

"This is a simple demonstration of the AT-327 Multimode Filter from Triangulum Research.
The AT-327 is a multimode filter based on the Aries AR-327; a filter designed by Dennis Colin in 1975 for Aries Inc. in Massachusetts. Dennis Colin designed many important filters for ARP, Aries, and Oberheim, but the Aries filters are hard to come by. Their design is similar to that of the ARP 1047, but was simplified to reduce cost and make use of newer components that had come on the market as of 1975.
I have a particular fondness for the rich and sometimes gristly analog timbres produced by the Aries System 300 modules, and as challenge to myself, decided to adapt their designs to the very popular eurorack standard.
This is the first character in the series."
"Focusing on Filter/Resonator 1047. As usual I record the session with the modular, not focusing on musicality or composition. Simply enjoying frequencies. It sounds pretty good on the Neumann monitors, now that its in a nice walnut case ;)"
"The Townshend Studio was unveiled on Thursday 10 October at the University’s Ealing site. The new studio arose from Pete Townshend looking for a home for his synthesisers, leaving a legacy for the next generation and a catalyst for creativity.
The collection includes some of the most influential instruments in the development of electronic music. It comprises 12 principal synthesisers including the ARP Model 2500 (1970), used on 'Quadrophenia', and the rare and sought-after Yamaha GX-1 (1975), one of only 10 made with a retail price of over 60,000 USD on release, plus many other instruments played by Townshend throughout his career.
'It’s my hope that the studio will be a creative space for learning, collaboration, experimentation and play, inspired by the musical and artistic legacy of Ealing, an area integral to the development of British music in the 1960s,'
said Pete Townshend."

One more "Synth Museum" to add to my destination list. :)
"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"
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."
