Differences between JD-800 and JD-990

 The Roland JD-990 is the Supermodule of the JD-800. It have extended capabilities and is a "big plus" to any setup.I have seen many setups with more than one JD-990 in the rack. 

1. Expanded wave ROM (6MB vs. 4MB)
2. Ability to use a 8MB expansion board
3. 4 additional outs
4. True stereo engine
5. Osc sync
6. Cross-mod (FXM)
7. Osc structures that allow ring mod and serial dual filters
8. Additional LFO waveforms
9. MIDI CC control of parameters
10. Tempo-sync delay
11. Polyphonic portamento
12. Performance memories
13. Additional multi-timbral slots
14. One patch can keep full effects in multi mode

The Original Internal Sound Demos

Here’s how to hear the “ROM Play” demo songs built into the JD-800.


Each mode (Single/Multi) has one demo song.


Select Single mode Or Multi mode.
While holding EXIT, press INC/YES.

Press YNC/YES and playback will begin.
Press DEC/NO and playback will stop.


Press EXIT once again to return to Single mode.


* During ROM Play in the Single mode, the informations of phrases are appeared in the display.

The JD-800 have two good internal demos, one for each mode (single or multi-timbral).

Mode			Server 2  (Ok, at Google Docs)	Size	Time
Single Mode			Part 0	977 Kb	1:02
Single Mode			Part 1	707 Kb	0:45
Single Mode			Part 2	1097 Kb	1:10
Single Mode			Part 3	641 Kb	0:40
Single Mode			Part 4	566 Kb	0:36
Single Mode			Part 5	533 Kb	0:33
Multi Mode			Multi Demo	660 Kb	1:36

Note: This are 128kbps mp3 files, so I reduced the overall quality. I want upload better quality sound files, but have been short in time. Anyways, the sounds are great.

See the movies in the other posts. They have great samples of what great sounds this synth is capable.


Edited:


SynthMania posted a nice video with the the 64 classic factory patches! Thanks!
