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.

Like it is already mentioned in the manual, one of the the 8MB SR-JV-Boards (19 available) fits into the JD990. IMHO the "Vintage Synth"board would suit best, because it expands this synth with a lot of raw synth only waveforms (who would use a JD for pianos/orchestra etc anyway)..
The available WaveformCards for the JDseries aren't very interesting (Drums, Piano etc)..

Some extra information need for possibilities to expand ROM and BANKs memory.

There is only:
Oscillators - 6MB of ROM waveform data (expandable to 16MB), 4 osc. per patch
Memory - 3 banks x 64 patches (expandable), 3 drum kits with 61 sounds

Will be glad to get some useful opinion about, after good experience with them.
Thank you!
