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.

Combined with an expansion card, this unit offers a fantastic array of beautiful sounding waveforms. The programming is intuitive and flexible and the most of the presets are great starting points. I use mine for recording so the polyphony isn't a problem, though I can imagine that it would for some in other settings. I haven't heard a better sounding digital synth and I paid $350 for mine with the orchestra expansion card (looking for a vintage synth card if anyone has one for sale) and some additional memory. Whenever someone compliments a patch in one of my tracks, it's almost always the JD

Yes, the JD-990 can be directly programmed from the JD-800 - nice if you have both!!! The JD-990 is more powerful but more button pushing, rotating the knob and menus. Having both really is having it al:-)

Some one has mentioned that you can program the JD 990 from a JD 800 keyboard unit. Does anyone know if this is true.

Just bought a JD-990. I used to have a JD-800 back in the early 90's and always really liked it. Still getting used to the 990 and it really reminds me of my old Roland S-760, similar programming etc. It came with a Vintage Synth Expansion board. Most of the presets on this expansion board are [beep] e but whats good about it is that it provides extra waveforms for programming. To be honest I'd say around 80% of the waveforms on offer are pretty [beep] e.. slap basses..ewwww! Thats why this is a programmers synths, you need to ignore those dodgy waveforms and make use of the excellent proramming available.
