About the patch banks e some of old material here.

The old classic 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.  

 

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.
