Oberheim Xpander

Restored, Professionally Owned & in Excellent Condition

Overview

We are delighted to present this Oberheim Xpander, a superb example of one of the most sophisticated analogue polysynths ever created.
Designed by Tom Oberheim’s team during the golden era of American analogue innovation, the Xpander represents the pinnacle of Oberheim engineering — a true hybrid masterpiece that marries the lush, organic depth of analogue oscillators with one of the most flexible modulation architectures ever implemented in a MIDI-equipped synthesizer.

Released in 1984, the Xpander was a technological tour de force, featuring six discrete voices, each effectively a complete monosynth, coupled to an extensive modulation matrix and multi-mode filters. Its sound palette remains legendary — capable of producing rich, evolving textures, weighty basses, and intricate soundscapes that continue to inspire composers, producers, and collectors alike.

Equally admired by collectors, studio professionals, musicians, and synth enthusiasts, the Xpander endures as one of the most musically rewarding and technically advanced analogue synthesizers ever made.

This example has been professionally owned and carefully preserved for nearly three decades.

Condition

This Oberheim Xpander is presented in excellent condition, graded 9/10 under RL Music’s in-house professional evaluation system, applied to all collector-grade instruments to ensure transparency and confidence for discerning buyers.
The control surface, panel graphics, and end cheeks all remain in outstanding shape with only the lightest evidence of use. The display is bright, the encoder actions smooth, and all functions perform exactly as they should.
Internally, this unit is pristine — a testament to its low-use studio life and careful custodianship. The wood end-cheeks do have some marks on them in places, which we would consider to be normal wear for a 40+ year old portable synthesizer.

Servicing & Restoration

This instrument was fully serviced by Ben Rossborough at Cyberwave EMS in March 2025, ensuring optimal calibration and long-term reliability.
Upon its arrival at RL Music in April 2025, the Xpander underwent a comprehensive inspection and assessment by Kent Spong at KSR (Kent Spong Restorations), who confirmed its exceptional internal condition and flawless operational status.

This Xpander requires no further work and is presented in ready-to-play, collector-grade condition.

Provenance

Our client, a professional musician best known as the live programmer for The Chemical Brothers, acquired this Xpander from a specialist dealer in Tokyo in 1997, while on tour with the band.
The instrument was never taken on the road and has remained in our client’s private studio ever since — a stable, climate-controlled environment where it has been lovingly maintained and occasionally featured in studio productions.

Notably, this particular Xpander can be heard on several releases from the Mancunian house label Ten Lovers Music, giving it an appealing musical provenance for those who value authentic studio lineage.

Accessories

This Xpander is supplied with:

  • A custom-made aluminium flight-case
  • The original Japanese and English user manuals
  • The original factory patch sheet

Waldorf Wave – 16-Vo...

Professionally Serviced, Rare Shadow Edition Example in Very Good Condition

Overview

We are delighted to present this Waldorf Wave – 16-Voice Shadow Black Edition, a magnificent example of Waldorf’s flagship hybrid wavetable polysynth and one of the most ambitious electronic instruments ever produced.

Representing the culmination of the PPG/Waldorf lineage, the Wave combined deep digital synthesis with true analogue filtering to create a sound that remains as inspiring today as when it first appeared in 1993. Its vast, hands-on interface and powerful modulation system made it a studio centrepiece for artists seeking uncompromising creative depth.

Equally prized by musicians, producers, collectors, and investors, the Wave endures as both a remarkable creative instrument and a testament to early-1990s German engineering excellence.

This Shadow Black Edition example, configured with 16 voices, is offered through the RL Music Brokering Serviceon behalf of a long-term UK owner and is one of only a small number of these special-finish units ever built.

Condition

This Waldorf Wave is presented in very good overall condition, graded 8.5/10 under RL Music’s in-house professional evaluation system, applied to all collector-grade instruments to ensure transparency and confidence for discerning buyers.

There are some light signs of age-related wear visible in areas of the panel finish, entirely consistent with a 30-year-old instrument, but nothing that detracts from its inspiring presentation or function. The control surface, display, and hardware all perform exactly as intended, and the instrument remains very visually impressive — clearly well cared for and maintained throughout its life.

1. Keybed and Key Discolouration
The key surfaces exhibit an ivory discolouration from age. We believe the Wave employs the Fatar TP/8S keybed. All keys operate perfectly and there is no functional issue, but for buyers who prefer a brighter appearance, there are potential cosmetic restoration options — either through careful whitening treatment or replacement of the key-tops. Both routes would involve some effort and cost and are entirely optional, as the instrument performs flawlessly. If you are interested in exploring these cosmetic possibilities, please contact us prior to purchase.

2. Display Brightness
The back-lit LED display functions perfectly with no segment loss, but its fixed brightness level is relatively low. There is no user adjustment for display intensity, so the Wave is best viewed in a softly lit environment for comfortable editing and navigation.

Servicing & Restoration

The instrument was evaluated and bench-tested by KSR in October 2025, confirming full operational status ahead of sale.
Following purchase, a comprehensive post-sale service will be carried out by KSR, including PSU re-capping, power-conditioning, calibration, and other preventive maintenance to ensure long-term reliability.

During recent maintenance, a new set of front-panel struts was fitted — a known improvement over the original design — providing greater stability and a fully adjustable playing angle.

This post-sale service is included in the price, ensuring that the instrument leaves RL Music performing at its absolute best.

Provenance

Brokered on behalf of a UK client, this Wave has remained in the UK since 2009, when the current owner acquired it from another UK seller. It has spent the last sixteen years in a private home-studio environment and has been meticulously cared for throughout.

Technical Overview

  • Polyphony: 16 voices (expandable to 48)
  • Oscillators: 2 digital wavetable oscillators + noise source per voice, with user-editable waves and FM-assisted UPAWs
  • Filters/VCAs: Per-voice CEM3387 analogue section — 24 dB/oct low-pass + 12 dB/oct high-pass (BP configuration possible)
  • Modulation: 2 LFOs + 4 multi-stage envelopes per voice for extensive modulation and wavescanning
  • Multitimbrality: Up to 8 parts simultaneously
  • Operating System: OS 1.8 – 1.911
  • I/O: Standard factory MIDI and audio configuration

These specifications confirm the Wave’s position as one of the most flexible and sonically distinctive hybrid synthesizers ever made.

Unique Features

HxC Floppy-Drive Emulator — Installed in 2022, this modern SD-card-based replacement for the original 3.5″ floppy mechanism preserves the Wave’s appearance while vastly improving reliability. The supplied SD card includes multiple sound banks — notably the Drew Neumann set — and can be managed easily on any computer.

Shadow Black Edition Finish — Produced toward the end of Waldorf’s manufacturing run circa 1995, the Shadow Edition features a rare anthracite-black finish applied to only a small number of hand-built units. Functionally identical to the standard model, this version’s understated aesthetic underscores the Wave’s industrial design elegance and makes it particularly desirable among enthusiasts of high-end hybrid synthesis.

Accessories

This Waldorf Wave is supplied with:

  • a Brand new IEC Power-Cable (UK 3-pin plug type)
  • SD card with sound banks for the HxC system

Oxford Synthesiser C...

Professionally Serviced British Classic in Excellent Working Order

Overview

We are delighted to present this Oxford Synthesiser Company OSCar – w/MIDI, a beautifully preserved example of one of the most distinctive and forward-thinking British synthesizers ever built.

Designed by Chris Huggett, the OSCar embodied a unique fusion of digital precision and analogue warmth — combining digitally controlled oscillators with a true analogue filter and amplifier path. Released in the early 1980s, it stood apart for its bold industrial design and its adventurous sonic architecture, which offered both subtractive and additive synthesis capabilities long before such hybrid flexibility became commonplace.

Equally admired by musicians, producers, studios, and collectors, the OSCar remains a landmark in British synthesizer design — unmistakable in both sound and style.

This particular example is an original UK/EU production model, factory-fitted with MIDI, and offered through the RL Music Brokering Service on behalf of a long-term UK owner.

Condition

This OSCar is presented in very good overall condition, graded 9/10 under RL Music’s in-house professional evaluation system, applied to all collector-grade instruments to ensure transparency and confidence for discerning buyers.
There are light signs of age and use visible on the casing and control surfaces, consistent with a carefully used 1980s instrument. The screen-printing around the high-usage Volume potentiometer shows the most noticeable wear, but again, this is quite consistent with many other OSCars we have seen over the years. The distinctive moulded ABS body remains clean and intact, and all controls and keys function exactly as intended. Overall, this OSCar presents as a well-maintained and cherished example.

Servicing & Restoration

This OSCar was evaluated and bench-tested by KSR in October 2025, confirming full operational status ahead of sale.
Following purchase, it will undergo a comprehensive post-sale service by KSR, including:

  • Full power-supply re-cap and conditioning
  • Calibration and general health check
  • Minor preventive maintenance for long-term stability

This post-sale service is included in the purchase price to ensure the instrument is delivered performing at its very best, fully meeting RL Music standards.

Provenance

This OSCar has been in the possession of its current owner for around 20 years, having originally been purchased via eBay from a seller in Italy. The instrument was serviced in the mid-2000s by the well-known UK synth technician James Walker, who performed a general overhaul that included re-capping (extent unknown) and hard-wiring the two main PCBs together with jumper wires to improve reliability. Since then, the synth has performed flawlessly and has not required any further technical attention.

This particular OSCar left the Oxford Synthesiser Company factory with the factory-fitted MIDI interface, rather than having it retrofitted later.

Technical Overview

  • Oscillators: 2 digitally controlled oscillators with multiple waveforms, additive synthesis capability, and oscillator sync
  • Filter: Dual 12dB filters switchable to 24dB ladder mode, with low-pass, band-pass, and high-pass configurations and self-oscillation
  • Modulation: Single LFO with multiple destinations, plus an envelope generator for both filter and amplifier
  • Memory & Control: 24 patch memories, duophonic operation, factory-fitted MIDI
  • Output: Mono audio output with external input for filter processing
  • Power: UK/EU 220–240V model with hard-wired UK 3-pin mains cable

This combination of digital control, analogue signal path, and additive waveform design gives the OSCar its unmistakable sonic personality — from deep basses to rich, harmonic textures.

Korg Trident Mk1 w/M...

We are Brokering this instrument for and on behalf of our UK customer

Servicing Status: A full service was carried out by Kent Spong at KSR in December 2024. A health-check will be included as a parts of our post-sale quality assurance practice.

Remarks: 

This Korg Trident Mk1 has been in our client’s ownership for many years and they had a MIDI retrofit kit added, so this example does have MIDI. The Trident had been unused and stored for a while so KSR were commissioned to fully service it, which was only completed within the last couple of weeks so it’s fresh out of the workshop and ready for a new owner to enjoy it.

The cosmetic condition is excellent, and although not quite as pristine as the other Mk1 Trident we are offering for sale right now, it’s certainly another rare opportunity to find such a nice-looking example, and with MIDI.

Why Buy a Vintage Korg Trident MK1?

The Korg Trident Mk1 is celebrated for several reasons that make it a beloved instrument among synthesizer enthusiasts and musicians:

1. Triple Synthesis Sections

The Trident Mk1 combines three distinct sections:

  • Synthesizer Section: Offers a classic analogue subtractive synthesis engine with rich, warm tones.
  • Brass Section: Features ensemble-style brass sounds with a lush character.
  • Strings Section: Known for its silky, lush string ensemble tones, enhanced by onboard modulation options.

This versatility allows for complex layering and sound design possibilities that were groundbreaking at its release.

2. Polyphony and Layering

The Trident Mk1 provides an 8-voice polyphony in its synth section and 16-voice polyphony in its string section. The ability to split and layer sounds across the keyboard is a major draw, enabling deep, evolving textures.

3. Analog Warmth

The instrument’s fully analogue signal path delivers a warm, organic sound characteristic of vintage synthesizers. This analogue warmth is particularly cherished in modern music production, where such a character is often emulated digitally.

4. Onboard Ensemble Effects

The built-in ensemble effect is a standout feature, adding depth and lushness to the sound, especially in the strings and brass sections. This effect is integral to the Trident’s iconic sound.

5. Intuitive Interface

The Trident Mk1 has a straightforward, hands-on interface with dedicated sliders and controls for each section. This makes it easy to shape and blend sounds in real-time, a significant advantage for live performance and spontaneous creativity.

6. Build Quality and Aesthetics

The Korg Trident Mk1 has a robust build with a vintage aesthetic that appeals to collectors and musicians alike. Its wooden end panels and tactile controls exude a sense of quality and craftsmanship.

7. Historical Significance

Released in 1980, the Trident Mk1 represents a pivotal moment in synthesizer history, bridging the gap between fully analogue machines and more complex hybrid systems. Its sound palette was a staple in many genres, including progressive rock, new wave, and early electronic music.

8. Cult Following

Its relative rarity and unique features have given it a cult following. Musicians and producers who own one often praise its distinctive sound and character.

In short, the Trident Mk1 is a versatile, beautifully designed instrument that combines the best elements of early 1980s analogue synthesis, making it both a nostalgic and practical choice for sound enthusiasts.

Roland Jupiter 6 Eur...

We are Brokering this instrument for and on behalf of our UK customer

Coming into stock: February 2024.

Servicing Status: Serviced Feb 2024.

Remarks: This Jupiter 6 (serial # 333020) was purchased by our client some years ago and is only ever used in the home.  The cosmetic condition is excellent, and the whole synth only shows light indications of use with some marks to the panels, which we hope the photos provided will show, but this is a high-quality 40 years old vintage instrument.

The Jupiter 6 has been a hugely popular polysynth since it arrived in 1983. It offers aficionados that beautiful vintage polyphonic analogue Roland sound for a very reasonable cost compared to its sibling, the Jupiter 8.  Prices for these models in recent years have seen a significant uplift as vintage polysynths are getting rarer and rarer to find in good condition.

Our client, the owner of the synth, purchased it in 2005 from a UK seller, and this being a 240V machine would suggest it’s always been in the UK, so not an import. The JP6 has never been gigged, and the cosmetic condition stands as a testament to it being exceptionally well cared for throughout its 40 years since manufacture. 

This JP6 has the hugely popular Europa Modification implemented, which expands the capability of this already superb vintage polysynth; we also have printed copies of the Europa User manuals, which we will supply upon sale to the new owner. Additionally, the original aluminium end-cheeks have been overlayed with retro-style hardwood wood pieces, which are in excellent shape.  This ‘bolt-on’ cosmetic mod can be removed if unwanted, but it’s something we have seen on a few JP6, and it either adds or subtracts to the synth, which depends on your viewpoint. 

The Jupiter 6 is a professional-grade vintage instrument that’s only ever going to become more sought after and rarer, so here is your opportunity to buy a beautiful condition example, fresh from the hands of a master synth-tech (Kent Spong) and fully guaranteed by RL Music.

This Jupiter 6 is sold through RL Music with a 3-month warranty and operates on EU 220V~240V, and is supplied with an IEC power cable (UK 3-pin type) and the flight case pictured.

Packing & Shipping: 

We can ship this JP6 worldwide, although the packing, shipping & insurance costs are not included in the sale price below, so they are subject to quotation.  The synth s located with us in Reading, so you are welcome to collect if from us if you prefer.

There may be short delays in getting the packaging materials produced for shipping as they are custom ordered for the specific dimensions of each instrument.  We are happy to discuss your requirements, so please email us if you have any questions about the logistics and/or need a quote.

Price: £5,900 GBP

As this is a brokered sale, VAT does not apply to UK buyers. However, packing & shipping/insurance is subject to VAT @ 20% should you need the goods shipped.

SCI Prophet 10

We are Brokering this instrument for and on behalf of our UK customer

Servicing Status: Full service by KSR will be carried out post-sale,

Remarks: A very rare opportunity to own what has to be one of the most impressive looking synths of its era (1980), the mighty Prophet 10 and this example comes with a MIDI retrofit.

We could never have imagined that we would have to say this, but this Prophet 10 is the vintage original model (there’s a clue in the pictures), so not the 2020 Dave Smith re-issue Prophet 5 with extra voicing.

Who wouldn’t have had their mind completely blown away when this came to the market in 1980, a twin keyboard mega-polysynth…just wow!  And, to add the cherry on top, it was a Prophet 5 (CEM based version) with 10 voices, and stackable.  So yes, it’s huge in every respect; footprint and that fabled Prophet sound.

One of our dear customers, a well-known vintage synth user and very successful musician, MrFirechild, produced a brilliant demo of (just) the Prophet 10, in 2015.  You can see/hear the 3:34 music video on his YouTube Channel, or you can just click the link below:

https://www.youtube.com/user/MrFirechild

The current owner, our client, has only owned this for a short time, having purchased it in the UK from a specialist vintage keys dealer in 2019 (not us) – it was sold to our client as a  fully serviced unit. KSR has fully health-checked the Prophet 10 for us and it all checks out fine (it was serviced properly), although the original micro-cassette that would have been used to store and recall the poly-sequences on those tiny magnetic tape cartridges, no longer works (very common). 

Cosmetic Appraisal:

Overall, this Prophet 10 is in very good condition but does show some normal signs of use and its age.  We have taken some septic pictures that highlight the most obvious blemishes, but we think it’s a nice example that would make anyone a very proud owner.

This Prophet 10 operates on 240V or US 110V (switchable). It’s sold with a 3-month warranty. We will include an IEC power cable and a copy of the user manual (PDF only).

Packing & Shipping: We can ship this worldwide, although the packing & shipping cost is not included in the sale price below, and is subject to quotation.  We are happy to discuss your requirements so please email us if you have any questions on the logistics.

Sales Price: £9,800 GBP

As this is a brokered sale, VAT is not applicable on the sale of this LAMM to UK buyers, however, the packing & shipping/insurance costs are subject to VAT @ 20%, should you need the goods shipped to you.  The Prophet 10 can be available for collection from us directly in the South of England (Reading, Berkshire).

Availability: This Prophet 10 is available for sale now.

Pictures: Click on the thumbnail for a higher resolution photo of the actual Prophet 10 for sale.  Kent at KST produced these pictures the Prophet 10 at his premises in Surrey, so these photos come straight from him using the best photo equipment he has available.

If you require specific pictures not already featured of the instrument then please contact us so we can request that Kent at KSR can accommodate your request, but there may be a short delay in getting this done for us/you.

KSR has undertaken an extensive cosmetic and operational restoration of this PS-3200, a project spanning several years but largely completed by the end of 2024 — thanks to the exceptional work of Kent Spong of KSR. The Korg has been held in our secure facility throughout 2025, so post-sale, we will have the instrument and all accessories fully checked before shipping or delivering to the new owner. This process will add approximately 10 to 14 days to the post-sale completion time.

Remarks

We have decided to offer for sale our complete Korg PS-3200 System, which forms part of the RL Music Vintage Synthesizer Collection. Over the last 22 years, we’ve retained a small number of the finest vintage synthesizers to pass through our hands — instruments we found particularly inspiring or significant. This PS-3200 is one such example and has been the subject of a full and detailed cosmetic and operational restoration by our trusted vintage synth technician, Kent Spong of KSR.

It is generally accepted that Korg produced only around 200 units of the PS-3200, although the exact number is difficult to verify. Whether 100 or 500 were made, production was certainly very limited, making this an exceptionally rare, hand-built instrument by any measure.

Due to the rarity and individual nature of instruments like this, we’ve taken great care to provide a comprehensive and honest description of this PS-3200. We encourage any prospective buyer to ensure they have all the information needed to make an informed purchase decision — and of course, we are happy to answer any questions directly.

Provenance

We purchased this PS-3200 from a UK seller (an experienced user) in 2015 and collected it personally from their studio in the South of England. At the time, the instrument was fully working but had not been professionally serviced, so we decided to retain it within our PS-series collection — completing the full lineup — and plan its restoration later.

The overall condition was original and very good but showing signs of cosmetic age typical for a 35+-year-old synthesizer. We therefore elected to undertake a full operational and cosmetic restoration. While the market for highly restored vintage synths has cooled in recent years — as values for unrestored examples have climbed — our motivation for this restoration was personal rather than commercial, as the PS-3200 has always been part of our private collection.

System Configuration

  • PS-3200 Main Frame
  • PS-3010 Keyboard Controller
  • PS-3001 Interconnect Cable
  • PS-3030 Remote
  • PS-3001 Interconnect Cable (second)
  • PS-3040 Dual Pedal
  • Kenton MIDI Retrofit Kit fitted

This particular PS-3200 includes the extremely rare PS-3030 Remote, a unique device allowing live performers access to the patch memories — a groundbreaking feature for 1978.

The PS-3040 and second PS-3001 cable were sourced later from private collections, completing the top-spec configuration that Korg could have supplied in the late 1970s.

A brand-new Kenton MIDI retrofit kit was purchased and professionally installed by KSR during restoration.

Historical Context

The Korg PS-3200 is a landmark in the evolution of analogue polyphonic synthesizers. Released in 1978 as part of Korg’s PS (Polyphonic Synthesizer) series — alongside the PS-3100 and PS-3300 — it combined 48-note polyphony, programmable presets, and unison detuning, placing it among the most technologically advanced synths of its era.

Built entirely by hand in very limited numbers, the PS-3200 was aimed at professional musicians and studios, and its cost placed it firmly in the high-end market. Its rich, layered analogue tone made it a favourite among those who could afford it, and today it remains one of the most collectible and musically significant instruments in Korg’s history.

About Restoration & Servicing

This PS-3200 has undergone what we term a Total Restoration — a complete operational and cosmetic overhaul. New solid-walnut cabinets were crafted by Ross Lamond (Lamond Design) for the mainframe, PS-3010 Keyboard Controller, and PS-3030 Remote. The original faux-wood cabinets were provided to Ross as reference for accurate reproduction. The result is visually stunning and structurally far superior to the original.

Restoration work undertaken includes

  • Complete disassembly of all control surfaces; all potentiometers and jack sockets removed and replaced.
  • Mainframe, PS-3010, and PS-3030 panels professionally powder-coated.
  • Custom screen printing using artwork commissioned and funded by RL Music.
  • New Switchcraft ¼-inch jack sockets throughout.
  • New power socket on the mainframe control panel.
  • Complete re-capping of the PS-3200, including PSU.
  • Cleaning and treatment of all PCB edge connectors.
  • Installation of Kenton MIDI Retrofit Kit.
  • Full system testing, calibration, and final assembly by KSR.

The edge connectors were found to be in excellent condition and were retained.

While KSR does not issue formal restoration reports, the scale and quality of this work are exceptional — the instrument now presents and performs closer to a brand-new PS-3200 than any unrestored example we’ve encountered. The project spanned several years, with hundreds of hours of expert labour and thousands of pounds invested.

This PS-3200 features the factory switchable power supply (100V / 110V / 220V) and is currently configured for 220V UK operation.

Packing & Shipping

We can ship worldwide. Packing, shipping, and insurance are not included in the sale price and are quoted separately.

Our intention is to have the PS-3200 system professionally packaged in custom-sized, export-grade boxes designed specifically for its components (minimum two boxes). Palletisation is not expected to be necessary. All consignments are fully insured for the sale value, and insurance documentation will be provided.

If requested, PCBs can be removed and packed separately, though this adds labour and material costs and may affect warranty terms.

UK buyers are welcome to collect the instrument from us in Reading, Berkshire, or we may be able to arrange personal delivery subject to location and quotation.

Sales Price

£25,000 GBP

As this Korg PS-3200 is owned by RL Music, VAT is applicable on the sale to UK buyers. Packing and shipping are also subject to VAT at 20% if required.

Arp Omni Mk2 #2471

We are Brokering this instrument for and on behalf of our UK client.

Service Status: 

A full service was carried out by Jim McKenna of Singing Cat Services in May 2023.

www.singingcatservices.co.uk

Remarks: 

The Omni Mk2 has becomes a difficult instrument to find in 2023, and to reveal one that’s in such beautiful condition as this example is, has to be a very rare opportunity. 

Background:

Our client purchased this Arp Omni Mk2 new from Chase Music in Manchester on 3rd September 1980 – we have the original sales receipt, although will not publish this as it contains personal data, but it will be provided to the buyer of this Arp. The provenance is therefore perfect for this 43+ year old Omni Mk2, 

Our client had assembled a modest & much valued vintage synth collection over the years, all of which we have the honour for selling for him as he has made the difficult decision to let these instruments pass to new owners/custodians. The Arp Omni Mk2 has been cherished, played & enjoyed only ever at home, during his 43 years of ownership.

Servicing:

As mentioned in the introduction, this Omni Mk2, went through a complete professional service by Jim McKenna Singing Cat Services in May 2023, as part of the pre-sale diligence in getting it ready for sale and in top operational condition for the new owner. We have been provided with a service report against the works carried out at Singing Cat Services, so please clock the link below so you can open up the PDF:

Singing Cat Services Serve Report – Arp Omni Mk2 #2471 PDF.

Also, our client had James Walker at Synth Repair Services carry out a service on the Omni Mk2 on 20th February 2008. We have the original receipt so will provide this to the new owner pos-sale but again, we will not publish this online as it contains personal data,

Condition:

Well, we would rate this as excellent condition, but you can decide yourself by looking at the pictures below. The final production date of the Arp Omni Mk2 was in 1981, so this example may be 46 years old, and it’s a completely original machine, so no mods, a true survivor and highly collectable like this.

Documents:

Our client had retained all the original documents since he purchased the Arp in 1980, so the following documents will be provided with the synth (see picture below):

The cosmetic condition of the front-panel is excellent, and tolex covering in good shape overall with the normal wear and tear that these have, and the metal catches and hinges are all present although the chrome on these are showing patina.

This CS-50 is sold through RL Music with a 3-month warranty. It operates on EU220~UK240V and is fitted with a UK type 3-pin plug. We can supply the user manual in PDF format.

Moog 16-Channel Voco...

Description

We’re delighted to present this beautiful example of the Moog 16-Channel Vocoder MBVO, manufactured in 1979 — one of the most revered and capable analogue vocoders ever produced.

As one of the very few full-spec Moog Vocoders to emerge onto the collector’s market, this 16-channel version delivers the unmistakable warmth, intelligibility, and tonal depth that made it the studio standard for professional voice synthesis and sound design in the late 1970s and early 1980s.

This example has been carefully maintained throughout its life, having spent its time in a private studio environment. It remains in excellent cosmetic condition, with only minor signs of age appropriate to a 45-year-old instrument. The construction quality of the Moog Vocoder is substantial, and the overall presentation reflects that heritage perfectly — a serious studio tool, engineered for professional use and longevity.

So good they built it twice!

In 2020, Moog Music reissued the original 16-Channel Vocoder design after more than four decades of absence from production. The decision to recreate such a complex and specialist piece of analogue equipment was a remarkable statement of intent — a tribute to the enduring reputation and relevance of the original 1979 model.

Moog’s reissue was built to the same circuit topology as the MBVO, retaining its fully analogue signal path, 16 filter bands, and iconic control layout. This was not a reinterpretation, but a faithful recreation — evidence of how well the original concept still stood the test of time. For collectors and musicians alike, it reaffirmed what those who have used the vintage units already knew: the Moog Vocoder is a benchmark in musical signal processing, and its sonic character remains as inspiring today as it was when first released.

Technical Specification

The Moog 16-Channel Vocoder MBVO is a fully analogue signal processor designed to analyse and resynthesise the spectral characteristics of one signal (the “modulator”) and impose them upon another (the “carrier”). This model, developed by Moog Music in the late 1970s, represents the pinnacle of classic analogue vocoding design.

The MBVO offers 16 independent filter bands spanning the full audio range, each with precision band-pass characteristics for exceptionally clear speech intelligibility and musical timbral control. The wide channel count, coupled with Moog’s high-quality VCF and VCA topology, delivers a uniquely natural and articulate sound compared to lower-band vocoders of the era.

Input and output routing is fully professional, with balanced line-level connections for both modulator and carrier paths, along with front-panel patch points enabling external filtering, envelope following, and formant shaping. A built-in voiced/unvoiced detector automatically controls sibilant articulation, and a pitch-tracking oscillator allows for synthetic speech or musical tone generation without an external carrier.

The unit is housed in a robust 6U 19-inch rack chassis, featuring high-quality illuminated switches and precision pots throughout — a testament to Moog’s engineering standards of the period.

Power is supplied via standard IEC mains input, suitable for UK and European voltage operation.

Servicing & Condition

This unit was fully serviced by Kent Spong at KSR in April 2025, ensuring it is performing to factory specification and ready for immediate use in any high-end studio environment.

Aside from this comprehensive KSR service, there are no prior maintenance or service records available for this example.

Cosmetically, the instrument presents really well — the front panel, controls, and chassis are all in excellent condition. These vocoders were typically rack-mounted and used in controlled environments, and this example is consistent with that history.

Provenance

This Moog Vocoder was inherited by our client from their father, meaning it has remained within the same family for over 40 years — a rare and reassuring provenance that adds further authenticity to this already exceptional example.

Accessories

No original accessories or documentation were provided with this item, but RL Music will supply a brand new IEC mains cable with the unit.

A PDF of the original Moog Vocoder Owner’s Manual is available from our archive (see Handy Links below).
