Synth Miniatures

RL Music, in collaboration with Ronaldo Lopes Teixeira Rolt, are delighted to announce the launch of Vintage Synth Miniatures

Back in 2007, we had an idea to offer high-quilty hand-made scale reproductions of vintage synths, but exhaustive searches to find the right person or business that could help us came to nothing, so we shelved the whole thing but still had the ambition to realise that idea.

Winding forward to late 2019, we finally had some success as we made contact with a massive vintage synth fan who also happens to makes scale models. Talk about the perfect fit!

Ronaldo Lopes Teixeira Rolt, an Illustrator and graphic designer, although now retired, is a Prog Rock lover and vintage synth fan. He’s lives in São Paulo, Brazil, and has been producing artwork and models for many years as a hobby. However, more recently he’s been promoting his ‘vintage synth miniatures’ through attending synth related events in Brazil, so his models and skills have reached a wider audience, but he plans to keep this labour of love as a hobby. Ronaldo was very interested to work with us at RL Music due to the obvious synergy and shared passion for vintage synths, so we offered him a way to channel some business back to him, and satisfy our own need to build our own vintage synth miniatures collection to go with our original instruments in the RL Music Collection.

Ronaldo was invited by Mr Michel Geiss (Jean-Michel Jarre’s partner) to make an exhibition at Synthfest in France last June 2019.

UVI, the well known French Music Software Company, commissioned Ronaldo to produce 53 miniatures (keyboards and drum machines) for them.

Ronaldo, a huge Prog Rock fan, decided to build Rick Wakeman’s rig from 1973…

How to Order

This first PDF (vintage_synth_miniatures_gallery) is a 21Mb file. It contains 77 images that Ronaldo has supplied us of the 1/6 scale models he has previously made.


This second PDF (Ronaldo_the_builder) is a 1.8mb file that has images of Ronaldo himself at some synth events with his collection, and shots from his workshop.


This last PDF (pricing_summary) is the current price list to purchase the models as listed in the gallery PDF above.  It also covers some Q&A you may have, but please call or email Richard if you have any questions if not covered in the document.  This price list will be updated when new models become available. Ronaldo is entirely open to requests to make just about anything vintage keys (drum machines, sequencers etc.) related, so ask Richard at RL Music for a quote to make your favourite instrument if you can’t see it listed.


We hope you are as excited as we are about this launch. These beautifully hand-made replicas are so cool, and you know already that they are instant collectables, and we all know what happens with ‘collectables,’ so get your shopping list together and give Richard a call or email.

Arp Quadra

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

Came into stock: Available from RL Music as at 21st November 2019.

Servicing Status: A full service by KSR will be carried post-sale.

Remarks: A really beautiful condition example of one of the best looking and sounding hybrid analogue polysynth of its generation – The Arp Quadra.

Produced between 1978 to 1981, the Quadra was adopted by many of the great bands of that era, probably the most notable being Tony Banks of Genesis – it’s beautiful and distinctive sounds can be heard in many of their albums of that period.

As the name suggests, the Quadra is 4 instruments in one, so a Bass synth, Polysynth, Lead synth, and String synth..all of which it does exquisitely well, and the built-in phase-shifter is to die for.  This all adds up to make this ‘must-have’ vintage keyboard for any serious fan. 

Here’s an excellent demo from a friend of ours – Marko Ettlich, otherwise known as RetroSound.  Marko delivers a beautiful demo of the Quadra in this short 3:50 piece:

Here’s an operational demonstration video of this actual Quadra that Kent at KSR produced for us on 15th January 2020:

Our client has owned this Quadra for over 10 years and very well cared for in his home. They commissioned James Walker to fully operationally overhaul the Quadra in 2009, so it’s had one of the worlds best synth-techs apply his skills to bringing the Quadra up to full spec with the required re-capping, new keyboard-bushes and calibrations etc.  As mentioned above, we will ask KSR to fully health-check and apply any service actions required post-sale.

Cosmetically, this 38+ year-old vintage analogue polysynth is in fantastic conditions you can see from the photos, with only some signs of wear to the metal panel in places. The main control surface is in remarkable condition with all the controls (slider/keys) intact and all mylar membrane switches working perfectly. The leather end-cheeks are in super condition throughout, with just some light wear as you would expect for a device this age.

This Arp Quadra operates on EU 220V.  We do have a user manual (in PDF format).  As the instrument is being Brokered through RL Music, it will be sold with a full 3-month warranty and can be shipped worldwide.  

Demos are available by appointment only.

<em>As with all Brokered Sales, the synth will be fully serviced post-sale before it’s sent to its new owner.  We do this to ensure that the instrument leaves us in perfect operational condition, and it is backed up by our full warranty to give the new owner complete peace of mind.  The servicing is carried out as a priority once the sale has been completed, and although it will delay shipping/delivery by a short time, we know from experience that customers are happy to wait.</em> 

Price: £8,990 GBP.

Availability: This Arp Quadra is available for sale now and can be reserved on deposit (20%).

EML ElectroComp 101

We are Brokering this EML-101 for a UK customer.

Came into stock: October 2019.

Restoration Status: KSR has already health-checked this pre-restored instrument and gave a 100% pass, so it’s ready for sale now.

Remarks: A super condition example of a rare machine to see available for sale these days, and in the scheme of things, not all that well known either.  To any aficionado of vintage analogue synthesisers, Electronic Music Laboratories involvement with music instrument goes back to the late 1960s, and much like the British EMS products, share a similar boutique feel to them, was sold to education facilities (universities and schools etc.) and oozes charter and uniqueness.  

The EML-101 was the third product to come out of Connecticut, in the USA, from 1972 and much like the Arp 2600, is 4 x VCO, 3 x VCF semi-modular system that offers duo phonic operation and patchable break-out to really dig into the sound design possibilities.  The architecture of the EML differs from what Arp and Moog were doing in their designs at that time as it uses op-amps to deliver much from stability in tuning, and reliability in general.

This particular example has been subjected to a sympathetic restoration, having a beautifully made wood cabinet & catches/handles for the keyboard and main synth.  The main control panel was left original, so shows a natural patina for its age, retaining that vintage feel and look.  Internally, the circuits are all in outstanding condition, being well mounted internally and of course, the whole system is fully operational.  The keyboard has had new bushes fitted and plays beautifully.  The mains transformer has been upgraded to a high-quality toroidal one with a very professionally installed voltage rectifier circuit. It operates on 220~240V rather than the original US voltage – this has made the 101 very stable and it has a very low noise floor. Surprisingly so for such an old instrument (47 years at most).

Our client, the owner, did not commission the restoration, so we don’t have any information on who did the work, but it’s of the very highest standard and certainly equal to anything we could have achieved if it had been one of our own projects.

Our client purchased the EML-101 from a Swedish collector/musician about 3 years ago, so it’s not been in his possession all that long, but they told us that It is an early version as it doesn’t have the ‘SEQ IN’ socket on the patch-bay, but has the ‘CM2’ out socket.

Kent at KSR has given a full health-check of the EML-101 and told us ‘it was perfect’ so there were no service items to carry out.  This verifies what our client told us as well, so we’re confident this is ready for sale and shipping now.

As mentioned above, the EML-101 runs on 220~240V, sold with a full 3-month warranty and a copy of the owners manual will be supplied (PDF) as well.

Price: £3,600 GBP.

Availability: This EML-101 is available for sale now.

Roland VP330 Vocoder...

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

Came into stock: September 2019.

Servicing Status: KSR have already fully serviced this VP330 in October 2019, so it’s ready for sale now.

Remarks: A nice condition example of the final production version of the iconic Roland VP330 Vocoder Plus with MIDI.

The VP330 was always loved for the rich analogue strings and alone make this instrument worth having, but the vocoder section with the external mic & synth inputs can deliver some very exciting voicing effects and timbres/triggering etc.  The VP330 has been used by many great artists, including Vangelis (Blade Runner), William Orbit and many others, so it has a long and distinguished history of use and a loving fan base. 

As mentioned above, Kent at KSR has carried out a full service on this VP330, and he told us that is was a ‘very nice clean example’ so there were no significant items to address in getting the instrument ready for sale.  Everything works 100% of course, including the retrofitted Kenton MIDI kit.  The main control surfaces/keys are all still looking good, with only some normal amount of water through age and use, and all the controls are present and intact.  The faux wood cabinet is in good condition also, with just some normal wear in places.

We’ve added a small collage photo below,  just to highlight the significant cosmetic blemishes, for full disclosure.

This VP330 Vocoder Plus operates on EU 220V and is supplied with the user manuals in PDF format. As the instrument is being Brokered through RL Music, it will be sold with a full 3-month warranty and can be shipped worldwide.  

Demos are available by appointment only.

Price: £2600 GBP.

Availability: This VP330 Vocoder Plus is available for sale now.

Prophet 5 Rev 3.2 w/...

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

Came into stock: Arrived at RL Music in July 2018.

Servicing Status: A full service by KSR has already been carried out (July 2019), so this Prophet 5 is ready for sale & shipping now.

Remarks: We are delighted to offer this super condition Prophet 5 Rev 3.2 with a Kenton MIDI retrofit installed. This synth has been in the ownership of our client for at least 20 years, although they told us it was in storage for at least the last 10 years, so they commissioned Kent at KSR to give the Prophet 5 a full overhaul/service etc.

The Kenton MIDI kit works flawlessly and brings the P5 into the DAW environment nicely which keeps the synth in step with all the modern music tech.

The service included full system overhaul (re-capped/calibration etc) and clean and keyboard assembly deep-clean with new bushings. The wood case has been also been refinished by hand. All the potentiometers and micro-switches were cleaned as well so all are smooth to touch and operate. We decided to leave the patches in the Prophet 5 as they are actually really nice, but we can install the factory resent if the buyer of this prefers.

These are unique sounding instruments and don’t be fooled in thinking the Prophet 6 is an alternative…it’s not. There’s a certain punch and warmth that this vintage Curtis chipset based system delivers, and you just have to listen to a-ha, Soft Cell and Genesis etc. to appreciate how influential this synth was to musicians in the 1980s….and still is today.

Did you know that the Prophet 5 can be set up to operate in different temperaments from equal-temperament? The operating system allows you to program microtonal adjustments across the keyboard, and store this in the synth memory locations. This is not something we have tried, but the user manual goes into some depth about how to achieve it.

Kent at KSR commented that this Prophet 5 was in really great shape internally and had clearly been really well maintained throughout its life, including the current owner’s custodianship.

The operational condition is flawless, and as you can see in the high-res pictures below, the overall cosmetic condition is very good for a 35+ year-old instrument, with only minor wear from use. The rear/back panel does show some marks and wear to the factory painted surfaces, so we wouldn’t rate this is a collector grade example, but certainly 8 out of ten, and it looks beautiful where it counts.

This Prophet 5 is sold through RL Music with a 3-month warranty and can operate on US 110V or EU 220V. Also, a user manual (PDF) will be supplied with the synth plus a UK IEC power-cable if required.

Price Post-Servicing: £5290 GBP.

Availability: This Prophet 5 Rev 3.2 w/MIDI is available for sale now.

Roland MKS80 & ...

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

Came into stock: Arrived at RL Music in July 2019.

Servicing Status: A full service by KSR has already been carried out (July 2019), so this MKS80 & MPG80 are ready for sale & shipping now.

Remarks: The classic rack polysynth combo is considered by many enthusiasts to be one of the best sounding vintage analogue rack-synths ever.

The MKS80 Super Jupiter is powerful velocity and pressure sensitive 8 voice/16 VCO analogue polysynth with that big vintage Roland sound, and a stack of modulation and editing facilities.  The accompanying MPG80 controller is an essential piece of kit if you want to really dig down into the programming and open up the synth’s capabilities, and is a joy to use.

This unit is the much sought after Rev.5 version of the MKS80 (see PCB pictures below) featuring the Roland IR3R03 VCO and VCF/VCA IR3R05 chipset, amongst other architectural differences to the earlier versions. Many say the Rev.5 comes closest to sounding like the Jupiter 8, but we’ll leave that debate to the internet to continue.

Both the operating panels MKS80 & MPG80 programmer are in excellent cosmetic condition as you would expect from a rack system, and the interconnect cable for the MPG80 is present. In addition, there original Roland M-64C Memory Cartridge is also supplied with this combo, providing additional samples for the MKS80.

Both units work perfectly and contain many of their original patches, and they’re simple to set up in your studio and get to work with straight out of the box. This combo has come to us from a private owner who is downsizing his synth collection, which is all in fantastic condition, so home use only for many years, which the overall condition verifies.

This combo sounds and operates like all MKS80 should, so if the sound is more important than looks, then this instrument will make a good studio workhorse for your vintage analogue poly needs.

The MKS80 is a EU220V machine, and as mentioned above, is supplied with the MPG80 interconnect cable and an IEC cable with UK-plug fitted. We will supply a copy of the user manual on PDF.

As the instrument is being Brokered through RL Music, it will be sold with a full 3-month warranty and can be shipped worldwide.

Demos are available by appointment only.

Price: £2990 GBP.

Availability: This MKS80/MPG80 combo is available for sale now.

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

Came into stock: June 2019.

Service Status: A full service by KSR has already been carried out (June 2019), so this Multimoog is ready for sale now.

Remarks: We are delighted to offer quite a rare machine to find in the UK these days, a Moog Multimoog.

This particular example has been in the ownership, and cared for, by Jessica Lauren (our client), for many years, and has been one of her main ‘go-to’ synths for all her live & studio work. Jessica is a very talented Jazz musician and highly skilled keyboard player. Her Multimoog can be heard on many of HER albums over the years, but she has decided it was time to let the Moog go to a new home.

It’s a brilliant mono-synth that has a sound character all of its own, boasting a punchy 24dB Moog Filter and some complex routing and performance options. In the right hands (like Jessica’s hands), this is a highly capable & versatile synthesizer.

Jessica posted a status update on your Facebook page about letting her faithful Moog go and said we could use it here, as it has some photos that will be of interest, plus it adds some provenance to the instrument – click the link below:

This Multimoog has been meticulously maintained over the years by KSR, so we can confirm it’s a perfectly working instrument, and used as an old Moog should be…for making music. It’s fair to say that the Multimoog is not a collector’s piece, but it’s in average cosmetic condition for its age and in pretty good shape. This is an honest machine with a fabulous provenance and will serve the right buyer for many more years to come.

The price for this Multimoog has been set to reflect it’s the condition, but looking at global prices for these models, it represents an absolute bargain, a steal, at the advertised price below, so we don’t think it will be available for long.

This Multimoog is sold through RL Music with a 3-month warranty and operates on EU 220V.

Price: £1,690 GBP.

Availability: This Multimoog is available for sale now.

EMS Synthi Mk2

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

Came into stock: Available from RL Music as at 9th January 2019.

Servicing Status: A full health-check by KSR will be carried out post-sale but this Synthi was fully serviced by EMS in October 2016.

Remarks: A fabulous opportunity to own a vintage EMS Synthi, and this example is in super all original condition throughout.

This Synthi (serial #4656KS so a Mk2 version) was purchased brand new by our client in 1973 so they are the original and only owner of this instrument. When purchased, this was a (complete) Synthi AKS model and therefore had the Keyboard Sequencer (KS) controller, but our client sold that some decades ago so it no longer comes included with this, hence it’s been advertised as only a Synthi, or Synthi A. There have not been any modifications made to this Synthi so it’s factory spec. One advantage to it being an ex-AKS model is that the PSU is rated to easily run external devices like the KS or DK series controllers.

Since 1973, this Synthi has been in regular home use only, and the owner decided to have a detailed service carried out by Robin at EMS in late 2016. We have the original EMS service receipt which we have scanned and made available to view below so you can see what was carried out.

The cosmetic condition is very good indeed, with only some wear to the screen-print along the matrix, which is not unusual. Both Spartanite cases are in excellent condition. The nickel latches & hinges show signs of oxidisation, which again is normal to see on a 45+ year-old synth, although they easily could be improved with some light restorative work if needed. In all, the instrument shows normal signs of ageing and has not any overt cosmetic restoration carried out, which we know for many people is important in terms of retaining authenticity.

Included in the sale (pictured), is a nearly-new Kenton Pro-Solo Mk2 with PSU and required cables to carry CV/Gate/Filter (cinch-jones connector) to operate this Synthi via MIDI. These are all included in the price, and worth around £200 GBP if purchased new/separately.

These iconic and truly amazing pure analogue music instruments are in great demand by professional users, and prices are being driven up fast on the second-hand market around the world, so now might be a good time to invest in one before they become ‘Vintage Buchla or RA Moog Modular’ prices.

We can’t think of a more iconic, truly portable synthesizer ever being made, and even today the design of the Synthi is considered a triumph of feature and form…incredible.

This EMS Synthi comes with way more than a full set of matrix pins, 35 in total, and 16 of them are brand new (all red), so the pin situation is covered.

KSR will give this Synthi a full health-check post-sale, but we have tested it extensively and can confirm it’s working perfectly, as it should really as Robin did all the refurbishment work only a couple of years ago.

This Synthi is set to operate on EU 220V~240V (front-panel setting). We were also supplied with the original EMS ‘Education manual’ for this model and the proprietary EMS power-cable (with UK 3-pin plug fitted).

As the instrument is being Brokered through RL Music, it will be sold with a full 3-month warranty and we can ship worldwide.

Demos are available by appointment only.

As with all Brokered Sales, the synth will be fully health-checked post-sale, before it’s sent to its new owner. We do this to ensure that the instrument leaves us in perfect operational condition, and it is backed up by our full warranty to give the new owner complete peace of mind. The work is carried out as a priority once the sale has been completed, and although it will delay shipping/delivery by a short time, we know from experience that customers are happy to wait.

Sales Price: £10,370 GBP.

Availability: This EMS Synthi is available for sale now and can be reserved on deposit (20%).

Moog System 12

‘Rare’ doesn’t come close to describing how few and far between these vintage original Moog Modulars are these days, and owners are simply hanging on to them whilst all the reissues from the new Moog company are making their transition into the market. The fact remains that savvy owners truly appreciate the historic value of these genuine ‘Bob Moog’ manufactured instruments, and why this lineage is what really counts at the end of the day, both emotionally, historically and commercially speaking – certainly in investment terms.

So why are we selling this beautiful Moog Modular System 12?

Well, this example comes from the RL Music private collection and has been fully professionally restored in 2015. We are releasing this for sale as we already own 3 other vintage Moog Modulars, and would like to raise some capital for some new vintage modular projects we have planned for this year, so here is a golden opportunity for someone looking to own a genuine piece of synthesizer history.

There is a considerable volume of material written about the amazing Bob Moog and his groundbreaking synthesizer designs from the 60s and 70s. Also, we all appreciate the outstanding sonic capabilities of these amazing instruments and why Bob Moog’s synthesizers changed the world, but to cut to the chase, here are the facts about this System 12 we have for sale.

Background history that we have:

The Moog System 12 unit has serial # 1039 and features some early ‘RA Moog’ modules from the time the Moog factory was located in Trumansburg, NY, and some modules with the later ‘Moog Music used after the move to Williamsburg. This is actually quite normal for these models as the assembly/manufacture date was around the early 1970s, so there would have been some RA Moog modules still available to use when assembling these systems. This puts an approximate age on this System 12 at 44 years old…not bad!

In the 1970s this System 12 belonged to the synthesist Jan Ternald of the Swedish psychedelic rock band Älgarnas Trädgård. After that, it ended up for unknown reasons in a small demo studio in Stockholm where it was left unused and forgotten until it was found and purchased by the last owner in 1984 (of whom RL Music purchased it from in 2015). It was mounted in custom-made flight cases in 1989 to allow touring and live performances. The original live setup also included two Mini Moogs, both stripped of the keyboards and mounted as rack modules, and an oscilloscope + a guitar tuner.

The system was then located in a recording studio in Stockholm, Sweden, and used in numerous productions until 1999. The last owner bought the System 12 to London In 2010 where it was located in the studio of an audio design company – it was continuous use (and professionally maintained) until it was sold to RL Music in 2015.

Modifications of note:

The two 921B oscillator modules have at some time prior to 1984 been modified by replacement of the original potentiometers with 10-round precision pots.

An IEC socket was fitted sometime during the lifetime of the System 12 to enable the system to be used in the EU. The power supply is rated to 220V, so it’s possible it was produced for the EU market by Moog, but we’re fairly sure that these systems were supplied with the standard 3-pin US power-socket from the factory back in the early 70s, so the IEC socket is more useful for EU users.

The System 12 arrived at RL Music without its original lid (lost over the years), so we have had a new one manufactured by Lamond Design, and then the whole system has been re-tolexed, with new nickel-plated hardware fitted by KSR in the UK to finish off.

All the 1/4 inch jack-sockets have been replaced with high-quality Switchcraft® panel mount sockets to improve connectivity. We decided to implement this upgrade as 44-year-old sockets can be very intermittent in connection, regardless of cleaning, and this can be very frustrating for users of voltage controlled/audio systems like these.

Restoration notes:

Our vintage Moog restoration expert, Kent Spong of KSR, undertook an extensive ground-up restoration on the System 12 during 2015. Other than the items noted above in the ‘modifications’ paragraph, no components that affected the sound character of the Moog were replaced (or needed to be in fact). We retained the original knobs though as these are a major cosmetic component to the aesthetic of this authentic vintage instrument.

We will service this System 12 prior to shipping to the new owner, so please expect a short delay of up to 2 weeks post-sale before it can be shipped out.

This Moog Modular System 12 is sold with a 3-month warranty and mentioned above, runs on EU 220V. We will include a selection of (used) 1/4 inch jacks with the sale if needed, but we do not have any spare cinch-jones cables, although can supply these from new here –

We will ship this Moog worldwide, so please ask us for a packaging & shipping quote for your preferred destination address.

Price: £13,990 GBP.
