Roland JD-990 Super JD

Roland JD-990 Image

The JD-990 is an enhanced version of the JD-800 and was the top o' the line JD-synth. Its rack-mount design and impressive power and functionality within the studio paved way for the hugely successful JV-series rack modules which lead, ultimately, to the XV-series monster-modules! The JD-990 is a digital synth with 6MB of ROM sounds with "analog-like" edit parameters and features. These include lowpass filtering, ring modulation, osc. sync, frequency cross-mod, etc. The JD-990 is also compatible with JV80 and JD800 expansion boards.

The JD-990 has a large LCD display which makes editing very easy and intuitive, you can actually see the envelopes and LFO rates. There's an on-board multi-effects processor with Delay, Reverb, Phaser, Distortion, Chorus, and EQ. For the studio, the JD-990 has MIDI IN/OUT/THRU and eight outputs in four stereo pairs. The JD-990 can hold one internal expansion board and the best choice is to put the Vintage expansion in it because that gives you about 512 patches (Only 255 from JV-series!) of which 256 are specially programmed for the JD-990. It is used by Vangelis, The Prodigy, Apollo 440, ATB, and Mirwais.

One of our most passionate Community layout makers, popup, has made 20 separate MIDI controllers/editors for the JD-990 (for MIDI Designer for iPad only). It's one per expansion pack...

This represents a ***colossal*** amount of work and a huge gift to the Community. Check it out here:

NOTE: we make MIDI Designer, the platform, but the controllers are made and shared by passionate users. MIDI Designer comes in a Lite version (free) and a Pro version.

JD 990 one of the world's best modules. The rest Roland surpasses it far level one JV, XP, XV. unfortunately Japanese terrible the good things are recognised badly. It would have been necessary to continue to improve it JD 990, more polyphony, wave, but not, they went into an other direction (wrong) JD etalon, curiosity, interesting, intuitive, nothing which cannot be compared with something else. Filters like this, converter... simply wonderful. All starting is a joy with him.

It's an epic synth with some famous sweeps and patches such as the Pizza Hutt preset #43 used extensively in dance music (as heared on SynthMania). You can truely compose a whole tune with just a JD-990, as it features a wide variety of sounds and drum kits. I'm selling mine ( but I've have a lot of fun tinkering sounds of all sorts.

Hi. I have the JD990, JV1010, JV2080, XV5080 and had the JV1080 with almost all cards in various combinations, and what you asked is almost subjective. I did many tests comparing the same ROM sounds in all these machines, and had mixed results. Some sounds sounded better in one machine, some in another, there was clearly NO case of one machine being better in all sounds. To my ears, the JV1010 and JV1080 generally sound more retro and "gritty" while the JD990 sounds more sharp, bright and fast. The XV5080 is more lush and rounded, the JV2080 more gentle. All are great!

OK, so I have a Roland XV-5080 & a JV-1010 & I just purchased off Ebay, "Roland SR-JV80-04 Vintage Synth Expansion Board". (didn't arrive yet) Can anybody tell me how the XV-5080 sounds, with the Vintage Synth board installed, -VS- the JD-990 w/Vintage Synth board installed? Does the JD sound better in some way? I know the XV is 1 hell of a monstrous sound module. The Vintage Synth board has 256 patches that "are specially programmed for the JD-990". Can I get the same sound/quality with my XV? Does the JD have some special/better filters in it or something, compared to the XV?
