Roland JD-800 – best (vintage) digital pad synthesizer?

Since we often talk about analog (or virtual-analog) keyboards, our attention to this sample & synthesis instrument might surprise you. Be that as it may, its analog surface, analog-like sonical richness and overall sound quality enables the JD-800 to fit perfectly into a modern sound & recording studio.


Personally, this is my favourite (modern) Roland synthesizer. I consider it more of an analog than a digital instrument. Strictly speaking, it IS digital, but it behaves like an analog machine … And there’s another reason for this review – the Roland JD-XA will be taking off soon:

The JD-XA is a unique crossover synth that brings together analog warmth and digital versatility in one super-creative, no-compromise instrument.” (

We are, of course, very curious about this new Roland flagship. But let’s take one last look at its grandaddy, the Roland JD-800 …


The JD-800 is nearly 25 years old, but it’s still visually and acoustically stunning – state of the art, irrespective of its age. And it sounds incredible, even in 2015. If I needed to reduce my studio equipment to just three synthesizers (unimaginable, but considering this theoretically), I’d choose the Roland JD-800, the Sequential Pro-One and the Elka Synthex. These Glorious Three could cover practically everything I’d need in terms of making electronic music.

And IF I could keep just five instruments, I’d add the ARP 2600 and GRP A8.


Well, and IF that synth family grew to ten units, I’d add the John Bowen Solaris, Roland Juno-60, Korg PS-3100 and the Yamaha CS-60. (To be honest, I’d smuggle a few other fellows into the studio: the Oberheim OB-8, Prophet-5, MFB Dominion 1, Roland SH-5, Jupiter-4, Moog Prodigy, Analogue Solutions Polymath and maybe a few others, like the COTK Model 15, but please don’t tell anybody) …

Some knobs would be great!

How it all began.

End of the 80s: musicians were tired of uncreative DX-like synthesizers with bad user-interfaces providing only a limited fun-factor when it came to programming and creating personal sounds.


Yamaha’s DX-synths, Roland’s D-serie, Korg’s M1 and many other instruments had been sold in considerable quantities, but eventually musicians felt rather attracted to those old, truly bizarre and user-friendly analog synths – a sort of “retro” took place. “Some knobs would be great …”

Roland released the JD-800 in 1991. I remember the day I first saw it. When I strolled past it my step briefly halted. What a wonderful, well-designed instrument! There were already nice (analog) synths in my small studio, among them the Jupiter-8 – but no synth design I’d seen before had attracted me like the JD did. It wasn’t easy on my analog-synth-loving heart, but the Jupiter-8 had to go! In its place, a lovely JD-800 joined my collection. That was in no way a mistake, not at all!


I guess my fascination wasn’t shared by many in the musician’s world. “Some knobs would be great” was still in the air, but when the JD hit the market, most musicians ignored it! Too many knobs? Far too “retro”..? Who knows…

Well, the presets …

Maybe musicians were simply not keyed to such a powerful and totally creative instrument. But admittedly, Roland also made some conceptional mistakes! For example, the factory presets: some of them are beautiful, showing JD’s philosophy and sonical potential. “Massive Pad”, “Killer Pad”, “Iceman”, “Invocation” – just to name a few.

But then there are sounds like “Clavinut” or “LA MIDI’ed Piano”, “MIDI Guitar” etc. and you think: “What is that for? A sort of sample-rom-player? Why do I need those lovely faders while playing a piano?”

Maybe Roland thought that implementing a stock of “all-time-standard-sample-sounds” was necessary for the instrument to be a success. People wouldn’t buy a synth without a serious piano sound, now would they …?


(That has turned out to be a stupid idea in any case, as piano sounds are extremely difficult to reproduce! Playing a Yamaha CP-70B (electric grand piano), for example, doesn’t give you more than an idea of what the “soul” of a real piano can transport. And then there’s that tremendously important “feeling” when making music on a real piano, which still gets lost with a sampler or other digital substitute.)

Unbalanced factory presets were part of the conceptional failure. Roland made an even bigger mistake by releasing sound cards such as “Guitar” or “Accordion”! Who the heck needs an accordion on the JD? The sound cards should have been called “Filmscore”, “Eeeeerie Vocals” or “Special Sound Effects”, something like that …


All together, the synth ended up with a totally confusing concept: JD with an analog surface on the one side, and (partially) ordinary sample-rom factory presets and misleading sound-cards on the other …

The following sound libraries were available:

1. SL-JD80-01 Standard Drums
2. SL-JD80-02 Dance Drums
3. SL-JD80-03 Rock Drums
4. SL-JD80-04 Strings Ensemble
5. SL-JD80-05 Brass Section
6. SL-JD80-06 Grand Piano
7. SL-JD80-07 Guitar
8. SL-JD80-08 Accordion


So what is the significance of JD? Is it simply an extended sample-rom-player with the bonus of nice faders, or is it the creative programmer’s synth, producing unbelievable pads not to be made by any other instrument?

I think it’s the Creative One …

Structure of the JD-800

First, the JD is permanently in MULTI Mode. Ok, ok – you’re right, it’s in SINGLE mode, but each sound (PATCH) consists of up to 4 individual sounds (LAYERS). So, SINGLE mode is, in reality, a 4-part MULTI mode, isn’t it?

Each LAYER features:

  • 2 LFOs (5 waveforms incl. S/H and random): LFO 1 / 2
  • 3 envelopes (for oscillator, filter and amplifier): Pitch ENV, TVF ENV, TVA ENV
  • 1 oscillator (108 waveforms to choose from): vast modulation possibilities (incl. random pitch), pitch-bender and aftertouch can be activated individually with every LAYER, key-follow function from 0 to 200 % (for microintervals, etc.)
  • 1 multimode filter (Low-Pass, Band-Pass, High-Pass): vast modulation possibilities, “dirty” filter resonance
  • 1 amplifier: vast modulation possibilities incl. aftertouch (but no pan-modulation, sadly)


“At the heart of the instrument is a bank of waveform ROM containing 108 preset samples and waves sampled at 44.1kHz. This last fact should not be glossed over, because it is one of the reasons why the JD-800 sounds as glisteningly fresh and clear as it does.

The other is the fact that the JD-800 has separate micropocessors for its synthesizer section and keyboard scanning. This makes the JD lightning-fast in touch and response and makes it feel as immediate and controllable as early synths, which were not weighed down with overloaded processing.” 

(Julian Colbeck: Keyfax – Omnibus Edition, page 101)

4 simultaneous LAYERS means that you have 4 oscillators, 8 LFOs, 12 envelopes, 4 multimode filters – and much more – at your fingertips! This vast platform guarantees for stunning, complex sounds. And then there’s an impressive selection of potent EFFECTS (superb algorithms such as chorus, delay, phaser etc.) that lets the JD sound even bigger and more complex.


“The effects section of the JD is not under slider control, but you can chop and change the order of effects (do you want reverbed chorus or chorused reverb?), which is rare, and the effects are ultra high quality.”

(Julian Colbeck: Keyfax – Omnibus Edition, page 101)

You might be starting to realize that the JD-800 is no ordinary poly-synth!

Special Setup

Now, just to confuse you: there is a proper MULTI mode as well. It boosts 5 SINGLE sounds (each with own MIDI channel) and a Special Setup (drum kit). Sadly, the JD-800’s multitimbralism is a one-at-a-time configuration only. Furthermore, only a few of the great EFFECTS are available in MULTI mode, so you could easily leave that out and concentrate on the powerful 4-part SINGLE mode.


Ok, leave it out, but with one exception: the Special Setup!

“Though one drum map of sounds exists internally, the JD’s best drum performances come off Roland PCM cards that slot in, alongside new program cards, at the back. Most are taken from the Roland S-series sample library and feature eerily accurate TR-909 and TR-808 samples. Overall, the drum sounds are live, sibilant and inspiring.”

(Julian Colbeck: Keyfax – Omnibus Edition, page 101)

Be that as it may, the Special Setup is more than a source of drum sounds. It is a unique source of creative & experimental sound possibilities.


Each single note (!) on the keyboard can play its own sound (with individual sound settings), which absolutely blows your mind! It’s a great tool to recreate wavetables / PPG-like sounds, for example …

Plusses of the JD-800

First: Its hardware. 59 sliders, dozens of buttons and lights. The JD-design is magic!

Second: Its sound architecture. As explained before: you’ve got 4 LAYERS, so you end up with a total of 4 oscillators, 4 filters, 8 LFOs and 12 envelopes for a SINGLE sound! Not bad, really! Added to that, its sonic potential is enormous. You end up with brilliant pads, some of which may consists of only two LAYERS (well, 4 LFOs and 6 envelopes should be enough modulation material to start with!).


Third: Its sound!

“The JD-800 sounds like it looks: big, impresive, complex, deep, multilayered.”
(Julian Colbeck: Keyfax – Omnibus Edition, page 100)

Take your time exploring the instrument’s sonic power, which is almost endless. The JD guarantees years of programmer’s fun … and lets you produce unique musical textures full of character. The JD behaves like an analog synth, which is why you never get bored of playing it. As on the Juno-60 or the ARP 2600, the sounds entice out lovely musical ideas, intuitive improvisations. If an instrument reaches that goal, it’s truly a musician’s instrument. If you have one: keep it in your setup – there are not too many of them around!

Fourth: Its SYS-EX capabilities. “The JD-800 sliders can be set to send MIDI messages that can be recorded into your sequencer. When adjusting a selected parameter such as cutoff, resonance, panning, etc., the JD-800 transmits a series of system exclusive messages.”



Fifth: Its user’s manual. It’s simply one of the best ever published. Roland not only explains in great detail the instrument’s philosophy, but offers ideas for creative sounds, useful programmer’s advices and a variety of background-info …

Even today, there are not many digital synths that come up to the JD-800. The John Bowen Solaris is one of those few, and there are some great softsynths on the market as well. Still, the JD’s lovely hardware is unsurpassed, and its sound quality is TOP. We really now hope that the new Roland JD-XA will follow in the footprints of its great-grandfather …

The downside of the JD-800

First, Its hardware. (Joke.) No, seriously: a few of the JD-800 parts are prone to error. Some of the triangular knobs might stop working (contact problems), dusty faders might send data without being moved, and aftertouch / velocity of the keyboard might fail. (Red glue problem > that glue eventually tends to drip with time, resulting in sticky keys).


Second: Its (true) polyphony. 24 voice polyphony sounds great. But, to be honest … that’s a little misleading! Roland’s layer-philosophy is irritating, since a layer IS de facto one voice. If the JD were 24-voice polyphon (well, it is..), you’d only have one layer at your disposal. Or, using 2 layers reduces polyphony to 12. Three layers gives you 8-voice polyphony, four layers 6-voices. So the “perfect” JD with 8 LFOs and 12 envelopes, etc., is in reality a 6-voice instrument. Not really that exciting, to be honest …

What we miss …

The “perfect” JD-800 would contain:

  • a 76-note high-quality keyboard
  • a simple sequencer and / or arpeggiator
  • possibilities for pan-modulation
  • a HOLD button


Is the JD-990 an enhanced version of the JD-800?

Well, not really. Theoretically, the JD-990 is an extended JD-800 with more oscillator waveforms, ring-modulation, pan-settings, more outputs, etc. BUT it’s missing all those sliders! And the large LCD display is no real substitute for those, to be honest. The ideal JD-990 would have come in two parts: the synth unit and the programmer unit – just like the MKS-80 (& MPG-80) way back in 1984.

In absence of all the beautiful sliders, the JD-990 is reduced to a good-sounding (but still rather dull and passionless) sample-player, while the JD-800 remains – in our assessment – the intuitive & creative programmer’s / player’s synth.

BUT … you can use the JD-800 as a PROGRAMMER for the sound module. This is good news!


“Use the following procedure to enable the Transmit Edit function:

On the JD-800:
1) Press MIDI.
2) Use the CURSOR UP/DOWN buttons to select “TX Edit Data.”
3) Press the INC (increment) button to turn this parameter ON.

On the JD-990:
1) Press SYSTEM SETUP so it is lit.
2) CURSOR to “RX Exclusive” and use the VALUE dial to select ON-2.
3) Press SYSTEM SETUP to return to the previous screen.

You will need to enable this transmit function each time you turn the JD-800 on.”



JD-800 today

If you already own a JD-800 – buy another one*! That’s what I suggest, considering risks and unreliabilities that might surface one day. Owning (and loving) this instrument means you should think in decades, not years! One day dust, dripping red glue or other influences might damage it.

So, a second JD-800 could be the guarantee that you have access to this beauty for the rest of your life. Current street prices are surprisingly low (500-700 Euros), so the JD-800 …


… is a real bargain these days. * (I just picked up my third JD-800).

Concerning the instrument’s features and power, there is no other (vintage) digital synth I could more highly recommend.

PS: we’re looking forward to playing the new Roland JD-XA Crossover Synthesizer soon. It’s supposed to be a four-part, analog giant with true analog filters AND a four-part digital engine, PLUS an impressive selection of potent effects.


Update September 2015: we’ve tested the new Roland JD-XA – that brand-new hybrid synth with the BIG sound, but with some not-to-be-ignored weaknesses (that inadvertently result in a weakened final performance).

Roland JD-XA Crossover Synthesizer

Filed under 2015, Reviews

“Es genügt, einen Ton schön zu spielen” sagte der Komponist Arvo Pärt im Jahre 2005. Diese Aussage ist ebenso einfach wie ich auch exzellent: Es braucht kein Meer an Tönen, denn entscheidend ist der Klang. Dass so mancher Vintage-Synthesizer der 70er und 80er Jahre teils unerreicht hochwertige Klänge liefert, steht außer Frage. Doch tatsächlich leben wir “heute” in einer nahezu perfekten Zeit. Einerseits hat man – mehr oder weniger – noch Zugriff auf die Vintage Analogen, andererseits wird auch bei Neugeräten die wichtige Komponente des hochwertigen Klanges wieder zunehmend berücksichtigt. Doepfer, Cwejman,, MacBeth, Moog, GRP, Studio Electronics, COTK, John Bowen und andere Hersteller bauen hervorragende Synthesizer, die den “Klassikern” in nichts nachstehen. All diesen (alten wie neuen) “großartigen” Instrumenten ist Great Synthesizers gewidmet. _________________________________________________________ In 2005 composer Arvo Pärt said: “Playing one tone really well is enough”. In other words, it is sufficient to play one tone 'beautifully'. I agree with that. All musical efforts are focused on the sound itself. Although I studied classical music (piano and drums), it’s the electronic sound that inspires me. Synthesizers are the epitome of new sounds and exciting tonal spheres. Today, many companies produce high-quality - excellent! - synthesizers: Doepfer, Cwejman, MacBeth, Moog, GRP,, COTK, Studio Electronics, John Bowen and others. It's their products I'm really interested in ... apart from Vintage Synthesizers, which I have been collecting for 20 years. Subsequent to our former websites Bluesynths and Blogasys, Peter Mahr and I have now created GreatSynthesizers. We hope you like it.


  1. Caner Ekici

    Thanks for sharings

    Turkey, Bursa City

  2. Excellent review. I’ve just managed to find one of these at a reasonable price and cannot wait to pick it up!

  3. Theo Bloderer

    … if it’s in proper working condition you should be really happy with it. One of the great (great!) classic Roland synthesizers …

  4. Greg Dolhy

    When I lived in Pittsburgh Pennsylvania, one of the best music stores in town had a fire. They moved all the surviving equipment into a temporary location to continue sales. I was very lucky to find a JD-800 standing on end against a wall for sale at a fantastic price. After thoroughly checking it out and finding the only problem was a very smoky smell, I bought it with great excitement. Because the original box was destroyed, I carried the keyboard out the store under my arm and walked down the street to my car. Along the way, an elderly man with his wife were slowly coming my way up the sidewalk. As they reached me, the old man exclaimed “Wow, what kind of accordion is that!?” I just smiled and replied, “Oh yes, a very special one”.

  5. Theo Bloderer

    … the man knew about the JD “Accordion” card. An expert :o)

  6. Gabriele

    Excellent review. Where I can dowload the sysex of the patches used in your demos? Thanks.

  7. B Money

    There should be a major recall… the red gloop is a major Boo Boo and it’s the ONLY thing that stops this as the greatest synth EVER created…. I can’t believe there has been NO FIX from the manufacturer.

  8. Theo Bloderer

    … true, the red glue issue is annoying. I need to clean and fix my JD-800 at least once a year …

  9. Hi Theo,

    I’ve been considering picking up a Quantum, or a Solaris, or maybe the Sledge 2.0. But to my ears your demos of the JD-800 just smash all the rest. Guess it’s just the sound I’m really looking for. Problem is I’m short on space and really can’t squeeze the 800 into my work space. In your experience, with perhaps a controller like the kiwi technics and some creative programming is it possible to get the 990 to sound as good?

  10. Theo Bloderer

    Hi Scott … The JD-990 has the same sound quality and also some extra features (RingModulator, to name one). So yes, the warm, indepth sound is the same. I personally couldn’t do without those JD-800 sliders, but a JD-990 with controller is basically the same. And you don’t have to worry about “red glue” (keyboard issue), which is definitely a good point. Cheers – Theo

  11. Thanks, Theo! Your reviews and demos are among the best on the web. Much appreciated!

  12. RTT112

    Surprising demo,like a blade runner piece!!!new as old city part for JD-!!!

  13. You made the JD sound amazing. Lovely music, Theo!

  14. Cannot believe I have just got one of these for free!
    I do clearances and recently cleared out the basement of an old hotel which is where I got this from, its an amazing piece of equipment.

  15. Stefan

    To all JD-800 owners with a broken keyboard due the red glue problem or something else: I have saved my JD-800 by installing the fantastic kit created by the great people at Super Synth Projects:

    The kit contains a new flexible contact PCB and keyboard connector PCB. It is a bit tricky to install but the instructions and support are great.

    Highly recommended. They have just started a new production run (January 2023)…

  16. Brian C

    …and it still sounds great in 2024. It’s actually very reliable and relatively easy to clean. Many of them don’t have the red glue keys. I had my keybed replaced years ago bought one from Roland US parts. Many did. The epoxy is black. So don’t assume the red glue is used on any you see. Also, there’s a guy who sells me brand new original factory spare keys for it on Ebay. A few years ago I bought an entire set (has all but the high C). He’s in Turkey you’ll know when you see listing. I spent about $350 on the set but if you’re serious about your JD-800 you have to do what you have to do. If you’re repairing a bad Keybed these keys are also invaluable. If you keep it nice it’s still like playing a brand new instrument. And the common praise about the strings card set is actually true in this case. Some great samples.
