I've got some news for you. I programmed 303 sounds for KAWAI K4 and K4r, and I would highly appreciate if you included this information in your page. The sounds (303 and some more techno stuff) are available at HOTOP MUSIKSOFTWARE, Osnabrueck, Germany. Hotop has got an own sub-page in my Music Page, that you already visited.
Check the ULR http://www.dom.de/FreiRaum/ths for infos.
