Someone told you Roland JD-800 and JD-990 are great for pads? Yes, but there are more than pads there.

Meanwhile, enjoy this samples from the factory sounds.

Gandalf - The Roland JD-800 Custom White Synth

This is a very nice customization.

Jeff Toman of Customsynth.co.uk artistically created a beautiful new all-white look for Dave´s Roland JD-800, in the style of a classic '80s SH-101 synth.

You can see it at Dave´s site.

Also see the 29-image Flickr set showing Randel's synth barn in Essex, CT, adding custom parts onto an otherwise stock synth..


There´s a video of the Gandalf in action: a must see!

Software and Patches for the JD-800 and JD-990

There are very good professional software supporting  the Roland JD-800 and JD-990, but if you want a non-pay choice, these are the best.

The JD-800 Patch Organizer created by Laurent Lecatelier-Dudec (France), was released as freeware in 24/04/1999 (date in original author´s site) and is no more available from the programmer´s site.

In more recent years, Gwydion Elderwin (Australia) created a JD-800 Randon Bank Creator and a Jd-800 to JD-990 Bank Converter.

About the patch banks here.

The first I found many years ago, was compiled by Stephen Drake, the guy who kept most of JD material available for years. This site is proud to pay him our tribute. Thanks Stephen!
The first internet banks are so-so grouped, thus makes some sense.

Gwydion also have done a strong work removing duplicates from hundreds of patches, adding lots more and creating a library for each synth. Still is missing time to classify all that stuff into categories.

Missing all you my friends, I know business and daily life take time, but I would be happy to receive some news. 

The bank files are in .rar format. You need Winrar or compatible to extract it.

Roland JD-800 SE Especial Edition Patches (a Brazilian version not in the factory presets). This was an interesting remarkable work from great Brazilian musicians with new exclusive patches. Most people forgot to save that and lose the patches made by Roland's Brazil people. Some (few) requires the Strings card.

Keep Your JD-800 Clean

Just be careful with the Roland JD-800, clean it very often. 

Dust in the sliders, button and circuits can provoke a typical JD-800 berzerk (auto-programming...). 

This effect is like a ghost acting in the synth. If you don´t use to change program while playing, turn off the banks edit mode. (just press bank A-b-C-D to light off and then save the patch.


You will also note, when some parameter is changed because dust, a "point" will light in the painel, like if you have done it.

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
