anyone have the Roland Prelude KB factory styles download link
American or European versions ?

Hey Donny, long time no hear! I had a Prelude (Latin collection) back in the day. I'm not sure that Roland ever provided the factory content as a zip file. I believe that someone would have to export each one from the board's internal memory. I never did that, but perhaps someone else has them.

After the G70/E80 the ROM files weren’t visible to a computer, only the user files. So yes, the Prelude styles (all 130 plus however many ‘World’ styles there were) would have had to be saved individually…

I certainly don’t have that, and I’ve got most pre-Prelude styles and most from the EA7. It was a huge task for anyone, and in all honesty I’ve never even SEEN one!

Best of luck…
