Great modifications and maintenance: Roland JD-800 "Restyling"

Great modification and fantastic result!

Efrem, from Italy have done many improvements inside that make the Roland JD-800 more robust and easy to maintenance.

A great video from a synth lover.

He turned the Roland JD-800 in a module, removed the keybed and improved it.

The video show all parts he serviced. Very good ideas.

Pay atention to details and you will be surprised. I comment only a few.

Well, he removed the damaged keybed. here in the blog you will see another modification such like this. 

The headphones output in front make it easier.

The joystick was placed apart and it is on a temporary support.

The plastic over the card place is a great idea. Protect against contact with the flat cable and prevent also agaist dust.

I say dust? Oh my god! He made a total cleanup! Dust inside is the great problem of the JDs. 

Another great idea was to improve heat dissipation in the power source. 
The connectors are no longer soldiers which greatly facilitates maintenance.

Love to see all that. Thanks Efrem, our congratulations! 


UPDATE: This one is an update from him but due restrictions you need to click at the Youtube link to see it.

    Roland JD-800 Demo - Live Pads Piano Strings Organ Bass Leads

    Some nice Roland JD-800 demos by VisceralVoids.

    Despiste the record quality sound not being so good, it is easy to feel the great sound this machine makes.

    Look the demo of interactive programming. User comment:
    At 4:40 this video shows a pad that you can create live using the JD-800's effects and sliders. I am using a Roland DP-2 footswitch to hold the chord down while I set the JD-800's phaser & delay. Then I change the cutoff and rez, and pitch with the "pitch coarse" knob. To get the "whoosing" effect you could set LFO1 on the filter. JD-800's resonance in full effect here but this is not using high settings. Other sounds in this video include crystal rhodes, strings, piano, PPG sounds, catherdral organ, of course basses and leads.

    Free CD - Music for Starry Nights - A work on the JD-800.





    This is our new CD:  Music For Starry Nights

    It was done by a sort of brazilian and european musicians.

    My music in this collection is "The Inner Side of Mirror". It was done using ONLY the Roland JD-800 without any external effect.

    It´s a nice demo of the great capabilities of this synth.

    One of The 10 greatest synthesizers of all time

    I found this article at MusicRadar, very nice comments:

    The 10 greatest synthesizers of all time

    The machines that changed music

    9. Roland JD-800


    It was a difficult decision, putting the JD-800 on the list in lieu of the massively popular D-50. The latter is arguably the classic between the two and represented a major shift in Roland's approach to instrument design and sales. Yet the JD-800 was, frankly, a far better instrument.
    Like the D-50, the JD combined sample-based oscillators with a fairly typical signal path that included a resonant filter, envelope generators and the like. However, the JD-800 offered something not available on any other sample-based synthesizer: a bucket load of sliders. Yep, the JD harkened back to the analogue era, offering scads of real-time control (that, alas, could only be transmitted via SysEx). It was big, impressive and utterly sexy, even if it was made mostly of plastic.
    More than that, it sounded out-of-this-world. At a time when manufacturers were doing their best to cram as many grainy 8-bit low-rate samples into an instruments' ROM as possible, Roland used only hi-res stuff, resulting in outstanding sound quality.
    Alas, the JD-800 was released a decade too soon. The analogue revival was still years off and sales fizzled (at least by D-50 standards). However, Roland knew what it had, and the technology behind the JD-800 would pop up again and again in its best-selling series of rack-mountable MIDI modules.

    An user review - control back to the player instead of the computer

    I found this interesting review at ihavesynth.com

    Review: Roland JD-800
    Posted by Synthattica on 10/10/2009

    I'm going to go out on a limb and say the JD-800 is one of the greatest synthesizers Roland's ever produced.  Not because it is loaded with a ton of features, but because of it's sheer design that I wish Roland would take an opportunity to produce a new line of JD series synths.

    Just the LOOK of the JD-800 gives many keyboardists a "synth boner".  While constructed of molded plastic (metal side panels would have helped keep more of these around!), it's build could be described as a bit flimsy, but they were durable enough to be road worthy.

    It's the philosophy of this synth that I love so much.

    When the JD-800 arrived in 1992, people have had enough of analog (can you actually believe that?!?!?), and digital synthesizers were now all programmed with the idea that users would edit sounds using a computer, so real-time control was sacrificed.  The JD-800 was the first one to step in and say (you know what?  alpha dials suck!  So do tiny little LCD screens and silkscreened menus and graphs to guide you through the synths parameters."

    Before close examination, it looks like an 80's pop version of an analog synth, but it's anything but.

    What you get is a 26 voice ROM-based digital synthesizer.  The is ONE DCO that controls the sound source of a multitude of sampled waveforms.  After that, the rest of the programming is very familiar to analog synths, with multiple filter choices, envelope sections, dual LFO's, etc.  While this may not sound all that interesting, each sound layers up to 4 of these individual signal paths.  In this sense, the JD-800 becomes something like a super-charged D-50, except the joystick on the D-50 would be replaced with a mixer section.  Personally, I think joystick mixing would have been a better choice when they designed this synth.  It's sound is actually based on the D-50, though updated with better wave ROM.  While 26 voices was certainly a lot for 1992, keep in mind one voice each is used for each partial, so using all 4 partials limits you to a 6 voice instrument, plus two spare voices for whatever. At the end of the signal chain is an assortment of effects that are entirely LCD-menu driven, which makes them a little complicated to edit.

    The JD-800 is fully multi-timbral, and multi-mode is where you create your keyboard splits and complex layers.  I generally avoid multi use with this instrument since this synth is really created for thick pads and power-chords, and adding multi layers kills the polyphony.  Also in multi mode is where you'll find the drum section, an editable palatte of drum sounds, many of which became nearly as identifyable as the "digitalnativedance" patch from the D-50.

    While the JD-800 was packed with a multitude of usable sounds, Roland created a set of ROM cards that added more waveforms to work with, and come with a memory card to save your specific sound sets using those waveforms.

    If you're considering one of these boards, and I HIGHLY recommend them, you should know that there is NO sequencer or appegiator, this is strictly a performance synth.  I believe the panel controls transmit midi control parameters, though I've never used it in that fashion, so I'm not completely sure.

    The best uses for the JD-800: brass pads, warm strings, percussive sounds, pan flute type sounds, FX pads.  Drum sounds are usable.NOT good for: pianos, organs, acoustic instruments like upright basses and guitars.

    My personal recommendation: slave up a JP-8080, Wavestation, or D-50 to get some truly THICK Roland pads.

    Again, this synth doesn't have every bell and whistle, but you can see Roland's intent to replace their two legendary synthesizers: The Jupiter 8 (mostly in appearance and physical analog-style control) and the D-50 (in terms of sound).  What they wound up creating was a synthesizer that took sound control back to the player instead of the computer, and paved the road for the JV series of instruments, that would evolve into the XV series, then ultimately the Fantom series.

    An Collector Item

    I found this Roland JD-800 at RolandClans:


    Forum member, synth-owner say:

    Hedegaard:

    "I purchased it new in 1994 and have the brochure, card brochure, all manuals and all the cards except Accordion card. All cards bought from new back in the day, except strings card which I got off E-bay."

    It´s really a nice synth collection.
